Change Log

Overview

To configure SAML on Unified Access Gateway (UAG) you must have the following versions:

  • UAG 3.8 or newer
  • Connection Servers 7.11 or newer
  • For Windows 10 version 2004, deploy Horizon 2103 (8.2) or newer.

True SSO is optional.

  • SAML does not provide the user’s password to Horizon, which means that Horizon cannot perform single sign-on to the Horizon Agent machine and thus the Horizon Agent machine will prompt the user to login again. This usually means the user has to login twice.
  • To eliminate the second logon on the Horizon Agent machine, implement True SSO, which generates certificates for each user and then uses those certificates to automatically sign into the Horizon Agent machine.

Horizon Enrollment Servers ask Microsoft Certificate Authority servers to generate the SSO certificates for each user. This is an identity operation and thus the Horizon Enrollment Servers should be treated like Domain Controllers.

When you use Horizon Client to connect to a UAG that is SAML-enabled:

  1. It opens the default browser and prompts the user to sign into your SAML Identity Provider. If the user is already signed in then the user won’t see any sign-in prompt.
  2. After sign-in, the browser will then prompt the user to open Horizon Client.
  3. If the user locks the desktop then the user will need to know the local Active Directory password to unlock it.

Certificate Authority

Horizon Enrollment Servers can use a Microsoft Certificate Authority that already exists. Or you can install Microsoft Certificate Authority on the Horizon Enrollment Servers. If you have two Enrollment Servers, then install Microsoft Certificate Authority on both of the servers.

  1. Install Microsoft Certificate Authority from Server Manager > Manage > Add Roles and Features.
  2. Select Active Directory Certificate Services.
  3. The only Role Service needed for True SSO is Certification Authority.

The Microsoft Certificate Authority must be an Enterprise CA.

  1. After role installation, click the flag icon and then click the link to Configure Active Directory Certificate Services.
  2. In the Setup Type page, select Enterprise CA.
  3. In the CA Type page, if you already have a Root CA, then you can select Subordinate CA. Otherwise, you need at least one Root CA in your environment.

After Microsoft CA is installed, run the following commands:

certutil -setreg DBFlags +DBFLAGS_ENABLEVOLATILEREQUESTS
certutil -setreg ca\CRLFlags +CRLF_REVCHECK_IGNORE_OFFLINE
sc stop certsvc
sc start certsvc

If you just built a new Certificate Authority server then True SSO won’t work until you run gpupdate /force on all of your Domain Controllers and Horizon Agent machines. Or wait several hours for group policy to update.

Certificate Template

  1. On the Certificate Authority machine, from Start Menu, run Certification Authority.
  2. Right-click the Certificate Templates node and click Manage.
  3. Right-click the Smartcard Logon template and click Duplicate Template.
  4. On the Compatibility tab, change the drop-down for Certification Authority to Windows Server 2008 R2.
  5. Change the drop-down for Certificate recipient to Windows 7 / Server 2008 R2.
  6. On the General tab, name it True SSO or similar.
  7. Change the Validity Period to 1 day or similar.
  8. On the Request Handling tab, change the drop-down for Purpose to Signature and smartcard logon.
  9. Check the box next to For automatic renewal of smart card certificates, use the existing key if a new key cannot be created.
  10. On the Cryptography tab, change the drop-down for Provider Category to Key Storage Provider.
  11. On the Server tab, check the top box for Do not store certificates and requests in the CA database.
  12. Uncheck the bottom box for Do not include revocation information in issued certificates.
  13. On the Issuance Requirements tab, check the box next to This number of authorized signatures and enter 1 as the value.
  14. Change the drop-down for Policy type required in signature to Application policy.
  15. Change the drop-down for Application policy to Certificate Request Agent.
  16. At the bottom, change the selection to Valid existing certificate.
  17. On the Security tab, add your Horizon Enrollment Servers computer objects. This can be an AD group instead of individual servers.
  18. For each Enrollment Server computer object, on the bottom, check the Allow box for the Enroll permission. Click OK when done.
  19. Back in the Certificate Templates Console, right-click the Enrollment Agent (Computer) template and click Properties.
  20. On the Security tab, add your Horizon Enrollment Servers computer objects. This can be an AD group instead of individual servers.
  21. For each Enrollment Server computer object, on the bottom, check the Allow box for the Enroll permission. Click OK when done.
  22. Close the Certificate Templates Console.
  23. Back in the Certification Authority Console, with Certificate Templates highlighted on the left, if your environment has multiple CAs but this CA is dedicated to True SSO, then delete all templates from the right. Note: Domain Controllers must have certificates installed so make sure you have at least one other CA that is issuing Domain Controller certificates.
  24. Right-click Certificate Templates and click New > Certificate Template to Issue.
  25. Select Enrollment Agent (Computer) and click OK.
  26. Issue another certificate template but this time select the True SSO template.
  27. Your CA should now show the two templates.
  28. If you have a second CA, and if it is dedicated to True SSO, then delete all templates from that CA. Then configure it to issue the same two templates.

Enrollment Server

Horizon Enrollment Server must be installed on dedicated machine(s) that don’t have any other Horizon components installed.

  35. In Horizon Console, if you go to Monitor > Dashboard and then click VIEW in the System Health section.
  36. On the left go to Other Components. On the right go to the tab named SAML 2.0. You should see your SAML Authenticator.

Enable True SSO

Login to one of the Connection Servers and open a Command Prompt as administrator. The commands in this section have case sensitive parameter names. These commands are vdmutil, not vdmadmin.

Run the following command to add each Enrollment Server. Notes:

  • For the --authPassword fields, you enter "*" (with quotes) to be prompted to enter the password instead of specifying it at the command line.
  • --authAs fields do not include the domain name since domain is a different field.
vdmUtil --authAs admin-username --authDomain domain-name --authPassword admin-user-password --truesso --environment --add --enrollmentServer enroll-server1-fqdn,enroll-server2-fqdn

Run the following command to see the available certificate authorities and certificate templates for a particular domain.

vdmUtil --authAs admin-username --authDomain domain-name --authPassword admin-user-password --truesso --environment --list --enrollmentServer enroll-server-fqdn --domain domain-fqdn

Run the following command to enable the Enrollment Servers for a particular domain. This syntax configures the Enrollment Servers as active/passive (failover). Note: certificateServer is the CA name from the previous command and not the server’s FQDN.

vdmUtil --authAs admin-username --authDomain domain-name --authPassword admin-user-password --truesso --create --connector --domain domain-fqdn --template TrueSSO-template-name --primaryEnrollmentServer enroll-server-fqdn --secondaryEnrollmentServer enroll-server-fqdn --certificateServer ca1-common-name1,ca2-common-name --mode enabled

Run the following command to see the SAML Authenticators configured in Horizon Console.

vdmUtil --authAs admin-username --authDomain domain-name --authPassword admin-user-password --truesso --list --authenticator

Run the following command to enable True SSO for a particular SAML Authenticator. Enter either ENALBED or ALWAYS.

vdmUtil --authAs admin-username --authDomain domain-name --authPassword admin-user-password --truesso --authenticator --edit --name authenticator-name --truessoMode {ENABLED|ALWAYS}

For more info, see Command-line Reference for Configuring True SSO at Omnissa Docs.

If you prefer to load balance your Enrollment Servers instead of active/passive, do the following:

  1. On a Connection Server, run adsiedit.msc.
  2. Change the Connection Point to dc=vdi,dc=vmware,dc=int.
  3. Change the Computer to localhost and then click OK.
  4. On the left, expand Properties, and then click Global.
  5. On the right, double-click Common.
  6. Find pae-NameValuePair in the list and Edit it.
  7. Enter cs-view-certsso-enable-es-loadbalance=true and then click Add.
  8. Click OK a couple times to close everything.

You can view the status of True SSO in Horizon Console.

  1. In Horizon Console, go to Monitor > Dashboard and on the right, in the System Health section, click VIEW.
  2. With Components selected on the left, on the right is a tab named TrueSSO.

This article applies to all Horizon versions 2006 (8.0) and newer.

Change Log

Planning

Cloud Pod Architecture lets you publish a single icon that load balances connections across multiple pools in multiple pods in multiple sites (datacenters).

  • Global Entitlements – Entitlements are the same thing as published icons. When you create an entitlement (local or global), you are publishing an icon from a pool.
    • For local entitlement, the icon is only published from one pool.
    • For global entitlement, the icon can be published from multiple pools. The pools can be in one pod or from multiple pods.
    • Don’t configure both global and local entitlements for the same pool.
    • A single pool can only belong to one global entitlement.
    • For applications, only one application per global entitlement.
  • Pod Federation – Global entitlements can’t be created until a Pod Federation is created. This federation could be one pod or multiple pods.
    • The pods can be separated into sites. Each site can contain multiple pods.
  • Global Load Balancing – Use NetScaler GSLB or F5 GTM to connect Horizon Clients to a globally available Horizon Connection Server. The connected Horizon Connection Server then uses Global Entitlements to select a site/pod/pool.
    • When a user launches a Global Entitlement, the Connection Server selects a pod based on the Global Entitlement Scoping, which can be All Sites, Within site, or Within Pod. This is from the perspective of the Connection Server the user is currently connected to. Horizon will prefer the local pod if possible.
    • Users or groups can be assigned to Home Sites. Global Entitlements can be configured to prefer Home Sites over the normal site/pod selection criteria.
  • Dedicated Assignment – For Dedicated Assignment pools, global entitlement only helps with the initial connection. Once the user is assigned to a desktop then that desktop is always selected. Users are not automatically provided with a desktop from another site if the site containing their dedicated desktop has gone down. The desktop request will fail because the dedicated desktop isn’t available. The administrator could configure a separate Global Entitlement for the users to provide a floating desktop until such time the original site recovers. That floating entitlement should be arranged to deliver desktops from other sites as required.
  • Firewall Ports – The Horizon Connection Servers participating in Cloud Pod Architecture communicate with each other over TCP 135, TCP 22389, TCP 22636, and TCP 8472. Make sure these ports are open. More info at Ray Heffer VMware Horizon 7.4 Network Ports for Cloud Pod Architecture. 

  • RBAC – Horizon Console includes a new administrator privilege: Manage Global Sessions. The regular Administrators role has access to multiple pods. The new Local Administrators role can only manage the local pod.

Cloud Pod Architecture Topology Limits Horizon 8 at Omnissa Docs:

  • Max users = 250,000
  • Max Pods = 50
  • Max Sessions per Pod = 12,000
  • Max Sites = 15
  • Max Connection Servers per Pod = 7
  • Max Horizon Connection Server Instances = 350

Traffic flow (Rob Beekmans – VMware Horizon View Cloud Pod – unwanted routing?):

  • Use F5 GTM or NetScaler GSLB to connect users to a Horizon Connection Server in any pod. If active/active, use proximity load balancing to control which pod is initially accessed.
  • The Horizon Connection Server looks up the Global Entitlements to determine the destination pod for the Pool.
  • User’s PCoIP session goes through the initially connected Horizon Connection Server and across the DCI (Datacenter Interconnect) circuit to the remote pod. There’s no way to re-route Blast/PCoIP through a Horizon Connection Server in the remote pod. In fact, the Horizon Connection Servers in the remote pod are never accessed. You need sufficient DCI bandwidth to handle this Blast/PCoIP traffic.
  • Note: Horizon Cloud Universal Broker doesn’t have this problem.

  • Omnissa Access
  • App Volumes
  • Horizon Cloud Pod Architecture

  • Global Load Balancing

Initialize First Pod

  1. In Horizon Console, expand Settings and click Cloud Pod Architecture.
  2. On the right, click Initialize the Cloud Pod Architecture feature.
  3. Click OK to initialize.
  4. A status page is displayed.
  5. On the right, feel free to rename the federation by clicking the Edit button. This is the Federation, not the Pod.

    • Enter a new name.
  6. On the left, expand Settings, and click Sites.
  7. On the right, in the top half, highlight the first site, and then click the Edit button to rename the Default First Site to be more descriptive. Sites can contain multiple pods. Site is typically a geo location or data center.

    • Enter a Site name.
    • Site URL is a feature in 2406 and newer. It lets you specify a datacenter-specific FQDN that Blast is redirected to when Cloud Pod Architecture chooses a Horizon Agent machine in that site. This avoids sending the Blast connection across the datacenter interconnect. UAG 2406 and newer supports the feature.
  8. Click the Site to highlight it to reveal the Pods on the bottom half of the window.
  9. Highlight the pod on the bottom and click Edit to make the name more descriptive.

    • Enter a Pod name.
  10. See Omnissa 2080522 Restoring View Connection Server instances in a Cloud Pod Architecture pod federation.

Additional Pods – Join Federation

  1. Connect to Horizon Console in the second pod.
  2. On the left, expand Settings, and click Cloud Pod Architecture.
  3. On the right, click Join the pod federation.
  4. Enter the name of an existing Horizon Connection Server that is already joined to the federation.
  5. Enter credentials and click OK.
  6. The Join status is displayed.
  7. On the left, expand Settings, and click Sites.
  8. If this pod is in a different site, then in the top half of the window click Add to create a new site.
  9. Give the site a name and click OK.

    • Site URL is a feature in 2406 and newer. It lets you specify a datacenter-specific FQDN that Blast is redirected to when Cloud Pod Architecture chooses a Horizon Agent machine in that site. This avoids sending the Blast connection across the datacenter interconnect. UAG 2406 and newer supports the feature.
  10. Highlight the first site.
  11. On the bottom, highlight the new pod, and click Edit.
  12. Rename the pod and put it in the 2nd site. Click OK.
  13. The top of Horizon Console shows you which Pod you are administering. You might have to refresh the page to see the correct Pod name after it was renamed.

Global Entitlements

Global Entitlements contain one or more Local Pools from one or more pods. Connections to the Global Entitlement can be load balanced across the member pods and pools.

Do not create both Global Entitlements and Local Entitlements for the same pool otherwise users might see two icons. Create the local pool, but don’t entitle it (i.e. don’t assign users). Instead, create a Global Entitlement and add the local pool to it.

  1. Before creating a Global Entitlement go to Inventory > Desktops or Inventory > Applications, click a pool name, scroll down to the Pool Settings section and record the settings. Your Global Entitlement must have the same settings.
  2. In Horizon Console, on the left, expand Inventory, and click Global Entitlements.
  3. On the right, click Add.
  4. In the Type page, select Desktop Entitlement or Application Entitlement, and click Next.
  5. In the Name and Policies page, give the entitlement (icon) a name. For Application Entitlements, it’s one Global Entitlement per application so include the application name.
    • Horizon 2006 and newer can specify a Display Name that is different than the name of the entitlement.
    • Horizon 2103 and newer can set a Federation Access Group to restrict administrator access to this Global Entitlement. You can create Federation Access Groups in the Horizon Console at Settings > Administrators, and on the right is a tab named Federation Access Groups. You can edit the Global Entitlement later to specify a Federation Access Group.
  6. Scroll down.
  7. Scroll down for more settings:
    1. You can configure tag restrictions (Connection Server restrictions) from this wizard.
    2. You can select a Category Folder where the published icon will be placed on the client’s Start Menu or Desktop. This feature requires Horizon Client 4.6 and newer.
    3. Configure Category Folder. You can type in a new folder or select an existing one. Specify whether the shortcut should appear on the Start Menu, Desktop, or both.
  8. Scroll down to the Policies section and configure the following. Note: these settings must match the Local Pool or you won’t be able to add the Local Pool to the Global Entitlement. Some of these settings can’t be changed without deleting the Global Entitlement and recreating it.
    1. For Desktop Entitlements, the User Assignment field (Floating or Dedicated) must match the Local Pools.
    2. Scope determines from which which site/pod the Local Pool is selected. Users connect to a specific Connection Server. Scope specifies if the Local Pool can be selected from any any pod in any site, from any pod in the same site as the Connection Server that the user connected to, or from the same pod as the Connection Server that the user connected to. For Dedicated Assignment pools, the user always connects to the assigned desktop no matter which Connection Server the user initially connected to.
    3. The Use home site checkbox tells the global entitlement to respect user home sites. When you assign a user to a home site, when the user launches the global entitlement, it tries to find a Local Pod in the same site as the user’s home site. This helps keep the user’s session close to the user’s data (e.g. home directory, roaming profile).
    4. Change the Default display protocol to VMware Blast. These settings must match the Local Pools.
    5. Horizon 2306 (8.10) and newer have a Session Distribution Policy to distribute sessions across the local resources in the Global Entitlement. Horizon 2309 (8.11) supports either Session Count or Load Index.
    6. For Desktop entitlements, you can allow users to Restart their machines or use Session Collaboration, or initiate separate sessions from different client devices. These settings must match the Local Pools.
    7. For Application entitlements, there’s a Pre-launch checkbox. If you need the Pre-launch feature, then enable the Pre-launch checkbox on at least one application, and entitle the application to the users that need the Pre-launch feature. These settings must match the Local Pools.
    8. There’s a checkbox named Client Restrictions. When this is enabled, you can add Client Computer Accounts to an AD Group and entitle the published icon to that computer AD group. The published icon can then only be accessed from the client computers in the AD group.

      Notes:

    9. For Application Entitlements, there’s a selection for Multi-Session Mode. Pre-launch must be disabled to enable this setting.
    10. Make other selections.
  9. Click Next when done.
  10. In the Users and Groups page, add users that can see the icon associated with the Global Entitlement. Click Next.
  11. In the Ready to Complete page, click Finish.
  12. Global Entitlements won’t work until you add some Local Pools to it. Make sure your Horizon Console is connected to the Pod that has the Local Pool.
  13. On the left, expand Inventory and click Global Entitlements.
  14. On the right, click the link for the name of the Global Entitlement. Global Entitlements are synced to every pod.
  15. Switch to the Local Pools tab and click Add.
  16. Select the local pools you want to add and click Add. Remember, only add one app per Global Entitlement. Also, you can only add pools from the local pod. To add pools from a different pod, you must point your Horizon Console browser to the other pod and edit the Global Entitlement from there.
  17. If the GUI won’t let you add the local pool then try it from the command line to see the actual problem. lmvutil parameter names are case sensitive. Some settings can only be changed by deleting the Global Entitlement and recreating it.
  18. Point your Horizon Console to another pod and view the Global Entitlements.
  19. On the right, click the hyperlink for the name of the Global Entitlement and follow the same procedure to add Local Pools. Horizon will automatically load balance user connections across all local pools based on the Scope policy (All Sites, Within Site, or Within Pod) in the Global Entitlement and Home Sites.
  20. A backup global entitlement delivers remote desktops or published applications when the primary global entitlement fails to start a session because of problems such as insufficient pool capacity or unavailable pods.
    1. Create a new Global Entitlement containing the backup pools.
      • The new Global Entitlement for backup should have the same settings as the production Global Entitlement.
      • You don’t have to assign anybody to the new Global Entitlement that will be the backup.
    2. Add Local Pools to the new Global Entitlement that will be the backup for when prod is down.
    3. Edit the production Global Entitlement.
    4. Scroll down to Backup Global Entitlement and click Browse.
    5. Change the selection to Backup Global Entitlement, select the Global Entitlement that will backup this one. Click Submit.
  21. Horizon Console, at Inventory > Desktops can show if a Local Pool is a member of a Global Entitlement. Scroll to the right to see the Global Entitlement column. This column doesn’t seem to be visible for Applications.

Monitoring

  1. Once Global Entitlements are enabled, a new Search Sessions node is added, which allows you to search for sessions across federated pods. Brokering Pod is the pod containing the Connection Sever that the user initially connected to to get the list of icons as opposed to the pod that contains the Local Pool that the session is actually launched from.
  2. The Monitor > Dashboard in Horizon Console shows the health of remote pods.

Home Sites

The Home Sites feature causes Global Entitlements to prefer local pools in the user’s Home Site before looking for pools in remote sites.

  1. Configure your Cloud Pod Architecture with multiple Sites and at least one Pod per Site.
  2. In Horizon Console, on the left, click Users and Groups.
  3. On the right, switch to the Home Site Assignment tab and click Add.
  4. Find a user or group for this home site, and click Next.
  5. Select the site to assign the users to and click Finish. This list of sites comes from your Cloud Pod Sites configuration.
  6. Home Sites can be assigned to both users and groups. User assignments override group assignments.
  7. Edit your Global Entitlement and ensure that Use Home Site is checked. You can optionally require that each user has a Home Site.
  8. Each Global Entitlement can have its own Home Site configuration that overrides the global Home Site configuration.
    • In Horizon Console, click the hyperlink for the Global Entitlement’s name, switch to the tab named Home Site Override, and then click Add.

  9. Since you could have a combination of default Home Site for user, default Home Site for group, and Global Entitlement-specific Home Sites, it’s helpful to know which Home Site is effective for each user and Entitlement.
    • In Horizon Console, in the Users and Groups node, switch to the Home Site Resolution tab. Find a user, and it will show you the Home Site Resolution for a specific Global Entitlement.

Before you can publish applications or RDS desktops, you must create an RDS Farm. An RDS Farm is a collection of identical (cloned) Remote Desktop Session Hosts. Applications must be installed identically on every machine in the farm. If you have different applications on different Remote Desktop Session Hosts, then these are different RDS Farms.

Once the RDS Farms are created, you publish icons from them by either creating a Desktop Pool or an Application Pool or both. When creating a Desktop Pool or Application Pool, all members of the RDS Farm are selected. It is not possible to select a subset of Farm members.

RDS Farms – Instant Clones

For a description of Instant Clones, see Instant Clones for RDSH in VMware Horizon 7.1 YouTube video.

  1. You select a snapshot from a master image.
  2. Horizon creates a template VM that boots from the master snapshot. After some prep, the template VM shuts down and creates a new snapshot.
  3. The template snapshot is copied to a Replica VM on every LUN (datastore) that will host RDS Farm VMs.
  4. For each datastore, Horizon creates a Parent VM on every host in the cluster. This parent VM is powered on and running at all times.
    • Horizon 2306 (8.10) and newer now default to no longer creating parent virtual machines.
  5. The linked clones can finally be created by forking the parent VM to new linked clone VMs. Notes:
    1. Once the Parent VMs are created, creating/recreating linked clones is fast. But it takes time to create all of the Parent VMs.
    2. And the Parent VMs consume RAM on every host. If you have multiple datastores and/or multiple pools, then there are multiple Parent VMs per host, all of them consuming RAM.
  6. You can schedule a periodic reboot of the Instant Clones, which causes the Instant Clone machines to refresh (revert) from the parent VM.
  7. Instant Clones require Distributed vSwitch and Distributed Port Group with Static Binding and Fixed Allocation. Standard vSwitch is not supported. Multi VLAN and vGPU for Instant Clones in VMware Horizon 7.1 YouTube video.

Create an Automatic RDS Farm

Instant Clones in Horizon 2303 and newer require vSphere 7 or newer. vSphere 6.7 and older will not work.

Master Image Preparation

  1. Make sure your RDS gold Agent has the VMware Horizon Instant Clone Agent feature installed.
  2. Make sure your RDS master Agent is configured for DHCP.
  3. Computer Group Policy – Make sure the Master VM is in the same OU as the Instant Clones so the Master VM will get the computer-level GPO settings. Run gpupdate on the master after moving the VM to the correct OU. New Instant Clones do not immediately refresh group policy so the group policy settings must already be applied to the master VM. See Omnissa 2150495 Computer-based Global Policy Objects (GPOs) that require a reboot to take effect are not applied on instant clones.
  4. Shut down the master image.
  5. Edit the specs of the master VM to match the specs you want the linked clones to have.
  6. Take a snapshot of the master image.
  7. In Horizon Console, on the left, expand Inventory, and click Farms.
  8. On the right, click Add.
  9. In the Type page, select Automated Farm, and click Next.
  10. In the vCenter Server page, select Instant Clone, select the vCenter Server, and then click Next. Notice that Composer is no longer an option.
  11. In the Storage Optimization page, click Next.
  12. In the Identification and Settings page:
    1. Enter a name for the Farm. A VM folder with the same name will be created in vCenter.
    2. Note: There’s no place to set the Display Name here. You do that later when creating a Desktop Pool.
    3. Scroll down to the Farm Settings section.
    4. Horizon supports Pre-launch. If pre-launch is enabled on a published app, when the user logs into Horizon Client, an empty RDS Session is immediately established. When the user double clicks an icon, the program launches quickly since there’s already a pre-launched session. When the user closes Horizon Client, the pre-launch session is disconnected for the duration specified here. The minimum duration is 10 minutes.
    5. For Empty session timeout, set it to 1 minute. For When timeout occurs, set it to Log off. You usually want the session to end when users close all of their applications.
    6. For Log off disconnected sessions, specify a disconnect timer. This is in addition to the idle timer configured in Global Settings.
    7. There’s a Allow Session Collaboration checkbox, which adds a VMware Horizon Collaboration icon in the system tray of the remote desktop, which lets you invite users to collaborate. See Session Collaboration for details.
    8. Max sessions per RDS Host will block connections if this number is exceeded. You can leave it set to Unlimited.
  13. Click Next.
  14. The Load Balancing Settings page lets you configure what metrics are used for even distribution of users across the farm. By default, only Session Count is considered. You can add other metrics like CPU or Memory. Click Next.
  15. In the Provisioning Settings page:
    1. Enter a Naming Pattern. Make sure the name includes {n:fixed=3} or something like that. Computer names must be 15 characters or less.
    2. In Farm Sizing, enter the number of machines to create.
  16. Click Next.
  17. In the vCenter Settings page, click Browse next to each option and make a selection. These are self-explanatory. Make sure VM Folder Location doesn’t have any spaces in it. Scroll down to see all options. Then click Next.
  18. In the Guest Customization page:
    1. Select an OU to place the new virtual machines. This should be an OU that is configured with group polices for the RDSH machines.
    2. Consider the Allow reuse of pre-existing computer accounts check box.
  19. Click Next.
  20. In the Ready to Complete page, click Submit.

To view the status of RDS Farm creation:

  1. Click the farm name.
  2. The bottom of the Summary tab shows you the State of the Publishing progress.

  3. You can watch the progress in vSphere Client. It goes through a couple longer tasks, including cloning the snapshot, and creating a digest file.
  4. Eventually the tab named RDS Hosts will show the new virtual machines.
  5. Once the RDS Hosts are created, you publish resources from them by either creating a Desktop Pool, or an Application Pool, or both.

Add more RDS Hosts to an Automatic Farm

To add RDS hosts to an existing RDS Automatic Farm.

  1. On the left, expand Inventory, and click Farms.
  2. Click the link for an automated farm.
  3. On the right, click Edit.
  4. Switch to the Provisioning Settings tab and change the Max number of machines. Then click OK.
  5. It should not take long to add the new VM.
  6. The RDS Hosts tab of the RDS farm shows the new RDS host(s).

Update an Automatic Farm

Master Image Preparation

  1. Power on the master session host.
  2. Login and make changes.
  3. After making your changes, shut down the master session host.
  4. Right-click the virtual machine, and take snapshot. You must create a new snapshot.
  5. Name the snapshot, and click OK.
  6. You’ll need to periodically delete the older snapshots. Right-click the master VM, and click Manage Snapshots.
  7. Delete one or more of the snapshots.
  8. In Horizon Console, go to Inventory > Farms.
  9. Click the farm name’s link.
  10. On the Summary tab, click Maintain, and then click Schedule.
  11. One option is to schedule Recurring reboots, which revert the RDS Hosts to a clean state.
  12. To push out an updated Master Image, change the Schedule to Immediate.
  13. Select Start Now, or select Start at a future date/time. Click Next.
  14. In the Image page, uncheck the box next to Use current golden image, select the new snapshot, and click Next.
  15. In the Scheduling page, decide if the reboot should wait for users to logoff or force them off and then click Next.
  16. In the Ready to Complete page, click Finish.
  17. The RDS Farm’s Summary tab (scroll down) shows you that it’s publishing the new image.

  18. After the image is published, on the RDS Hosts tab, you can check on the status of the maintenance task.

Instant Clones Maintenance

To perform Instant Clone Maintenance:

  1. If you click an Instant Clones RDS Farm name…
  2. And switch to the RDS Hosts tab, you can select a machine, and then click Recover, this causes the VM to be deleted and recreated, thus reverting to the master image snapshot.

  3. On the Summary tab of the RDS Farm, you can click Maintain > Schedule to schedule a reboot of every VM in the RDS Farm. Rebooting causes the VMs to revert to the master image snapshot.
  4. Specify how often you want the reboot to occur, and then click Next.
  5. In the Image page, you don’t have to change the snapshot. Click Next.
  6. Decide what to do about logged on users, and click Next.
  7. In the Ready to Complete page, click Finish.
  8. If you click the Maintain menu again, you can click Reschedule to change when the reboots are scheduled. Or click Cancel.
  9. If you click Schedule again, you can only schedule a one-time update, typically to replace the master image snapshot used by the RDS Farm.
  10. ESXi hosts running Instant Clones can be placed into maintenance mode without any special instructions.

RDS Farms – Manual

If you are building your RDSH Machines manually (e.g. cloned manually in vCenter; no Instant Clones), then add the manually created machines to a Manual Farm.

  • All RDS machines added to a single Manual Farm should be identical because Horizon will load balance across the servers in the farm.

To create a manual RDS Farm:

  1. Make sure the Instant Clone Agent is not installed on your manual RDS servers, and make sure you saw the screen to register the Agent with a Horizon Connection Server.

    • Verify registration at Settings > Registered Machines.
  2. On the left, expand Inventory, and click Farms.
  3. On the right, click Add.
  4. In the Type page, select Manual Farm, and click Next.
  5. In the Identification and Settings page, enter a name for the Farm. Scroll down.
  6. Scroll down to the Farm Settings section.
    1. There is a pre-launch option. If pre-launch is enabled on a published app, when the user logs into Horizon Client, an empty RDS Session is immediately established. When the user double clicks an icon, the program launches quickly since there’s already a pre-launched session. When the user closes Horizon Client, the pre-launch session is disconnected for the duration specified here. The minimum duration is 10 minutes.
    2. For Empty session timeout, set it to 1 minute. For When timeout occurs, set it to Log off. You usually want the session to end when users close all of their applications.
    3. For Log off disconnect sessions, specify a disconnect timer. This is in addition to the idle timer configured in Configuration > Global Settings.
    4. There is an Allow Session Collaboration checkbox, which adds a VMware Horizon Collaboration icon in the system tray of the remote desktop, which lets you invite users to collaborate. See Session Collaboration for details.
  7. Click Next.
  8. The Load Balancing Settings page lets you configure what metrics are used for even distribution of users across the farm. By default, only Session Count is considered. You can add other metrics like CPU or Memory. Click Next.
  9. In the Select RDS Hosts, select one or more identical Remote Desktop Session Hosts that are registered with Horizon Console. Click Next.
  10. In the Ready to Complete page, click Submit.
  11. If you click the farm name…
  12. On the RDS Hosts tab, you can click Add to add more registered RDS Hosts. Make sure every Host in the RDS Farm is identical.

Publish Desktop

To publish a desktop from a load balanced RDS Farm (Automatic Farm or Manual Farm):

  1. In Horizon Console, on the left, expand Inventory, and click Desktops.
  2. On the right, click Add.
  3. In the Type page, select RDS Desktop Pool, and click Next.
  4. In the Desktop Pool ID page, enter an ID and name. They can be different. The ID cannot contain spaces. Click Next.
  5. In the Desktop Pool Settings page:
    1. You can select a Category Folder where the published icon will be placed on the client’s Start Menu.
    2. You can type in a new category folder name or select an existing one. Also select Shortcut Locations.
    3. There is a checkbox named Client Restrictions. When this is enabled, you can add Client Computer Accounts to an AD Group and entitle the published desktop to that computer AD group. The published desktop can then only be accessed from the client computers in the AD group.
    4. Notes on Client Restrictions:
  6. Click Next.
  7. In the Select an RDS farm page, select a farm, and click Next. The farm can be either Instant Clone or Manual.
  8. In the Ready to Complete page, check the box next to Entitle users after this wizard finishes, and click Submit.
  9. In the Entitlements window, click Add.
  10. Browse to an Active Directory group, and click OK.
  11. Then click Close.
  12. If you go to Inventory > Farms, click your farm name, there will be a RDS Pools tab, where you can see which Desktop Pool is associated with this farm. An RDS Farm can only belong to one Desktop Pool.

Publish Applications

To publish apps from an RDS Farm (automatic farm or manual farm):

  1. In Horizon Console, on the left, expand Inventory, and click Applications.
  2. On the right, click Add, and then click Add from Installed Applications.
  3. In the Select Applications page, select a RDS Farm.
  4. The purpose of this wizard is to publish applications from an RDS Farm and then assign them to users (aka entitlement). The entitlements (aka user assignments) will apply to all of the applications you select on this page. If you want different entitlements for different applications, run this wizard multiple times and select different applications. Once the applications are published, you can change their entitlements individually.
  5. Select one or more applications. Notice that File Explorer is not one of the options. You can manually add that application later. Scroll down.
  6. There are additional options at the bottom of the Select Applications page. Notice the Entitle users box is checked by default.

    1. There’s a Pre-launch option for published applications. You can optionally enable it on at least one application, and then entitle the pre-launch application to the users that need the Pre-launch feature.
    2. Horizon 2309 and newer let you restrict applications to a Single Application Launch Limit.
    3. You can assign tags for Connection Server restrictions, which lets you control visibility of icons for internal users vs external users.
    4. You can select a Category Folder where the published icon will be placed on the client’s Start Menu and/or Desktop.
    5. There’s a checkbox named Client Restrictions. When this is enabled, you can add Client Computer Accounts to an AD Group and entitle the published application to that computer AD group. The published application can then only be accessed from the client computers in the AD group. Notes on Client Restriction:
  7. Click Next when done.
  8. The Edit Applications page lets you rename (Display name) the published icons. Click Submit when done.
  9. Click Add to select a group that can see all of the applications that you selected. This is the normal entitlement process.

    1. There is an option for Unauthenticated users, which is detailed at Entitle Unauthenticated Access Users to Published Applications at Omnissa Docs.
    2. Before you can configure Uauthenticated Access on published applications, you must add a Domain Account that will be used for anonymous access at Users and Groups > Unauthenticated Access.
    3. Then go to Settings > Servers and Edit a Connection Server.
    4. On the Authentication tab…
    5. …enable Unauthenticated Access, and select the Default unauthenticated access user account.
    6. Back in your entitlement, you select Unauthenticated Users, and entitle it to the Domain User that is your anonymous account.
  10. You can run the Add Application Pool wizard again to publish more applications with different entitlements (aka user assignments).
  11. If you click the name one of the application pools…
  12. …on the Entitlements tab, you can change the entitlements

Manual Application Publishing

Instead of publishing an existing application from the Start Menu, you can add an application manually:

  1. Go to Inventory > Applications, click Add, and select Add Manually.
  2. File Explorer is an application that has to be added manually. Select an RDS Farm and then enter the path to the application.

  3. When publishing Explorer, add the /separate switch. This prevents the full desktop from appearing when launching published Explorer through HTML Blast.
  4. There are more settings at the bottom of the page.

Icon for Published Application

  1. You can select an Application Pool, then open the Application Icon menu and click Associate Application Icon.

Published App Monitoring

If you click a Farm name, you can view Sessions connected to that Farm and the published application each user is running. Monitor > Sessions does not show published application information, but RDS Farm > Sessions does.

  1. In Horizon Console, on the left, expand Inventory and click Farms.
  2. On the the right, click the link for one of the farms.
  3. Switch to the tab named Sessions.
  4. As you scroll down the table you’ll see sessions with Type = Application.
  5. If you scroll to the right, you’ll see the Application Name in the far-right column.

Show application pools associated with RDS Farm

  1. If you go to Inventory > Farms, click your farm name…
  2. …and switch to the RDS Pools tab, you can see which Application Pools (published applications) are associated with this farm. You can click the link for a pool to be taken to the pool’s property pages.

Disable Application

Horizon 2012 (8.1) and newer let you disable an application pool. Go to Inventory > Applications, select one or more applications, click the More menu, and click Disable Application Pool.

When the application is disabled, the application icon is removed from Horizon Client at next refresh. If the user tries to launch the icon before it has been removed, then the message is “This application is currently not available”.

Anti-affinity

You can configure Horizon to restrict the number of instances of an application running on a particular RDS host. Here are some limitations:

  • If the user already has a session, then anti-affinity is ignored.
  • If the application is launched from within an RDS Desktop, then anti-affinity is ignored.
  • Not recommended for Horizon Mobile clients.

See Configure an Anti-Affinity Rule for an Application Pool in Horizon Console at Omnissa Docs.

Do the following to configure Anti-Affinity in Horizon Console:

  1. On the left, go to Inventory > Applications.
  2. On the right, edit an existing application pool.
  3. Scroll down. In the Anti-Affinity Patterns field, enter process names to match. Wildcards are supported. Each match is counted.
  4. In the Anti-Affinity Count field, enter the maximum number of process name matches that can run on a single RDS Host.

Use this post to build a Windows Server Remote Desktop Session Host (RDSH) that will be used as the source image for additional cloned Remote Desktop Session Hosts. Or you can build each Remote Desktop Session Host manually using the steps detailed in this post. Virtual Desktop is detailed in a separate article.

This post applies to all Horizon versions 2006 (aka 8.0) and newer.

Change Log

Hardware

  • The session host pools will use the same hardware specs (e.g., vCPUs, memory size, network label) specified on the master session host. Adjust accordingly.
  • Set the vCPUs to 8. Two is the minimum.
  • Typical memory for an 8-vCPU session host is 24 – 48 GB (e.g., 32 GB).
  • For New Hard disk, consider setting Thin provision. And increase the size so it can store the locally cached profiles (C:\Users).
  • The session host should be configured with a VMXNET 3 network adapter.
  • When building the master session host, you will probably boot from an ISO. When you are ready to create the pool (RDS farm), ensure the CD/DVD drive points to Client Device, and is not Connected. The important part is to make sure ISO file is not configured.
  • There’s no need for the Floppy drive so remove it.
  • If you have any Serial ports, remove them.

NIC Hotplug – Disable

  1. Users could use the systray icon to Eject the Ethernet Adapter. Obviously this is bad.
  2. To disable this functionality, power off the virtual machine.
  3. Once powered off, right-click the virtual machine, and click Edit Settings.
  4. On the VM Options tab, expand Advanced, and then click Edit Configuration.
  5. Click Add Configuration Params.
  6. On the left, enter devices.hotplug. On the right, enter false.
  7. Then click OK a couple times to close the windows.
  8. The VM can then be powered on.

VMware Tools

See Omnissa Product Interoperability Matrices for supported versions of VMware Tools with different versions of Horizon Agent.

The latest versions of VMware Tools resolve security vulnerabilities.

VMware Tools includes the Shared Folders feature, which prevents roaming profiles from being deleted properly. When installing VMware Tools, make sure you deselect Shared Folders so it is not installed.

After installing VMware Tools, open Registry Editor and go to HKLM\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order. Look in the ProviderOrder value on the right, and ensure that vmhgfs is not listed. If it is, remove it.

Install/Upgrade Dynamic Environment Manager (DEM) Agent

All editions of Horizon 2006 (8.0) and newer are entitled to Dynamic Environment Management (DEM).

  • Horizon Standard Edition and Horizon Advanced Edition are entitled to DEM Standard Edition, which only has personalization features that replace Persona. If you are using FSLogix Profile Containers for profiles, they you probably don’t need DEM Standard Edition.
  • Horizon Enterprise Edition is entitled to DEM Enterprise Edition, which has all DEM features, including Smart Policies, Privilege Elevation, etc.

DEM 2006 and newer Agents (FlexEngines) require additional configuration to enable DEM Computer Settings. You can either configure registry settings on each DEM Agent machine, or in DEM Agent 2103 and newer you can use an installer command-line switch. Both are detailed at Perform Installation with Computer Environment Settings Support at Omnissa Docs.

  • Group Policy Preferences can push these registry keys to the Horizon Agent machines. Or you can manually modify the registry in your master images. The minimum registry values are Enabled and ConfigFilePath as detailed at Perform Installation with Computer Environment Settings Support at Omnissa Docs. For the list of additional registry values, see FlexEngine Configuration for Computer Environment Settings at Omnissa Docs.
  • Command line install looks something like below. The command line installer switch sets the same ConfigFilePath and Enabled registry values as shown above. 
    msiexec /i "\\fs01\bin\VMware\DEM\VMware-DEM-Enterprise-2406-10.13-GA\VMware Dynamic Environment Manager Enterprise 2406 10.13 x64.msi" /qn COMPENVCONFIGFILEPATH=\\fs01\DEMConfig\general

To install DEM Agent:

  1. Make sure Prevent access to registry editing tools is not enabled in any GPO since this setting prevents the FlexEngine from operating properly.
  2. DEM 2406 (10.13) is the latest release.
    1. Horizon 2312 (8.12) ESB release comes with DEM 2312 (10.12).
    2. Horizon 2212 (8.8) ESB release comes with DEM 2212 (10.8).
  3. Based on your entitlement, download either DEM 2406 (10.13) Enterprise Edition, or DEM 2406 (10.13) Standard Edition. For ESB Horizon, download the DEM version included with your ESB version of Horizon.

  4. Run the extracted VMware Dynamic Environment Manager Enterprise 2406 10.13 x64.msi.
  5. In the Welcome to the VMware Dynamic Environment Manager Enterprise Setup Wizard page, check the box next to I accept and click Next.
  6. In the Destination Folder page, click Next.
  7. In Choose Setup Type page, click Custom.
  8. In the Custom Setup page, click Next. Note: the DEM Management Console is typically installed on an administrator’s machine.
  9. In DEM 2111 and older, in the Choose License File page, if installing on a Horizon Agent, then no license file is needed. DEM 2203 and newer no longer ask for licenses since DEM Console installs the license in the DEM Configuration Share. Click Next.
  10. In the Ready to install VMware Dynamic Environment Manager Enterprise page, click Install.
  11. In the Completed the VMware Dynamic Environment Manager Enterprise Setup Wizard page, click Finish.
  12. DEM is enabled using Group Policy and configured using the DEM Management Console.

Logon Monitoring

See Omnissa 93158 Information about changes in logon timing data format in Horizon form Horizon 8 2111 and Later.

By default, in services.msc, the VMware Horizon View Logon Monitor service is not running. Set it to Automatic and start it.

The logon logs are stored at C:\programdata\VMware\VMware Logon Monitor\Logs on each Horizon Agent.

Inside each session log file are logon time statistics.

Remote Desktop Users

In Computer Management (compmgmt.msc), at Local Users and Groups > Groups, edit Remote Desktop Users and add a group like Domain Users. Users can’t login to RDSH unless they are members of this local group. Instead of configuring this group manually on each parent image, you can also use Group Policy to configure it.

Remote Desktop Licensing Configuration

The only way to configure Remote Desktop Licensing in Windows Server 2012 and newer is using group policy (local group policy or domain group policy).

  1. For local group policy, run gpedit.msc.
  2. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing.
  3. Double-click Use the specified Remote Desktop license servers. Change it to Enabled, and enter the names of the Remote Desktop Licensing Servers. Click OK.
  4. Double-click Set the Remote Desktop licensing mode. Change it to Enabled, and select Per User. Click OK.
  5. In Server Manager, open the Tools menu, expand Remote Desktop Services, and click RD Licensing Diagnoser. If you don’t see this option, then install it as a Windows Feature under RSAT.
  6. The Diagnoser should find the license server and indicate the licensing mode. It’s OK if there are no licenses installed on the Remote Desktop License Server.

Microsoft FSLogix

Why FSLogix?

Microsoft FSLogix has two major features:

  • Profile Container is an alternative to DEM Personalization.
  • App Masking is an alternative to Omnissa App Volumes.

DEM has three categories of features: Personalization, User Settings, and Computer Settings. FSLogix Profile Container only replaces the Personalization feature set. You typically do FSLogix Profile Container for profiles and use DEM for User Settings and Computer Settings. Here are some advantages of DEM Profile Container over DEM Personalization:

  • FSLogix Profile Container saves the entire profile but DEM Personalization requires you to specify each setting location that you want to save. FSLogix is “set and forget” while DEM Personalization requires tweaking for each application.
  • At logon, DEM Personalization must download and unzip each application’s profile settings, which takes time. FSLogix simply mounts the user’s profile disk, which is faster than DEM Personalization.
  • FSLogix Profile Container has special support for roaming caches and search indexes produced by Microsoft Office products (e.g. Outlook .ost file).
  • FSLogix is owned, developed and supported by Microsoft.

Here are some FSLogix Challenges as compared to DEM Personalization:

  • FSLogix Profile disk consumes significant disk space. The default maximum size for a FSLogix profile disk is 30 GB per user.
  • High Availability for FSLogix Profile disks file share is challenging. The file server High Availability capability must be able to handle .vhdx files that are always open. DFS Replication is not an acceptable HA solution. One option is Microsoft Scale Out File Server (SOFS) cluster. Another option is Nutanix Files.

Omnissa App Volumes has some drawbacks, including the following:

  • Completely separate infrastructure that must be built, maintained, and troubleshooted.
  • Introduces delays during logon as AppStacks are mounted.
  • AppStacks can sometimes conflict with the base image or other AppStacks.

An alternative approach is to install all apps on the base image and use FSLogix App Masking to hide unauthorized apps from unauthorized users. No delays during logon.

Microsoft FSLogix is free for all Microsoft RDS CALs, Microsoft Virtual Desktop Access per-user CALs, and all Microsoft Enterprise E3/E5 per-user licenses. Notice that per-device licenses are excluded. See Eligibility Requirements at Microsoft Docs.

FSLogix Installation

Do the following to install Microsoft FSLogix on the Horizon Agent machine:

  1. Go to https://learn.microsoft.com/en-us/fslogix/how-to-install-fslogix#download-fslogix and click the download link.
  2. Extract the downloaded .zip file.
  3. In the FSLogix \x64\Release folder, run FSLogixAppsSetup.exe.
  4. Check the box next to I agree to the license terms and conditions and click Install.
  5. In the Setup Successful page, click Restart.
  6. Make sure the Windows Search service is set to Automatic and Running.
  7. If Office is already installed, then repair the Office installation after installing and starting the Windows Search Service.

FSLogix is configured through Group Policy or by editing registry values on each FSLogix Agent machine.

Windows OS Optimization Tool

  1. See Windows Operating System Optimization Tool Guide at Omnissa Tech Zone for details on this tool.
  2. Download the Windows OS Optimization Tool.
  3. Run VMwareOSOptimizationTool-x86_64.exe.
  4. On the Optimize tab, choose a template.
  5. Then click Analyze on the bottom of the window.
  6. Near the top of the window click the Common Options button and make your selections on each of the pages. Click OK when done.

  7. The top right box named Analysis Summary shows the number of optimizations not yet applied.
  8. Review the optimizations and make changes as desired. Then on the bottom right, click Optimize.
  9. The History tab lets you rollback the optimizations.
  10. The Finalize tab contains tasks that should be run every time you seal your parent image.
  11. The Update tab lets you re-enable Windows Update so you can update the parent image.

Seal and Snapshot

  1. Make sure the parent session host is configured for DHCP.
  2. Session hosts commonly have DHCP reservations.

  3. The VMware OS Optimization Tool has a Finalize tab that contains tasks that should be run every time you seal your parent image.
  4. Go to the properties of the C: drive, and on the Tools tab, click Optimize to defrag the drive.
  5. Run Delprof2 to clean up local profiles. Get it from http://helgeklein.com/download/.
  6. Run antivirus sealing tasks. For example:
    1. Symantec: Run a full scan and then run the Virtual Image Exception tool
    2. Symantec: run the ClientSideClonePrepTool
  7. Base Image Script Framework (BIS-F) automates many image sealing tasks. The script is configurable using Group Policy.
  8. Shutdown the parent session host.
  9. Edit the Settings of the parent virtual machine and disconnect the CD-ROM. Make sure no ISO is configured in the virtual machine.
  10. If Instant Clones, take a snapshot of the master session host.

  11. Use can now use Horizon Console to create RDS Farms.

Full Clone Post-Cloning Tasks

If you use vCenter to clone the machine instead of using Horizon Instant Clones, then after the machine is cloned, do the following on the cloned machine:

  1. Static IP – Configure a static IP address (or DHCP reservation).
  2. Windows Update – Run Windows Update. SysPrep disables Windows Update so you must run it at least once to re-enable it.
  3. Join domain – Join the machine to the domain if SysPrep didn’t do it for you.
  4. Active Directory OU – Move the Active Directory computer object to the correct OU.
  5. Horizon Agent – for manual farms, uninstall the Horizon Agent and reinstall it so it registers with a Horizon Connection Server.
  6. Antivirus – Re-configure antivirus. Instructions vary based for each product. Go to the antivirus vendor’s website and search for a cloning procedure.
  7. Firewall rules – Add the new machine to any firewall rules (PCoIP, Blast) between the Horizon Security Server and Horizon Agents.
  8. Horizon Console – In Horizon Console, add the new machine to a Remote Desktop Services farm.

Omnissa Horizon 2406: Virtual Desktop Pools

Last Modified: Jul 30, 2024 @ 5:18 am

This article details Horizon pool configuration for Virtual Desktops. RDS Farms and pools are detailed in a separate article at https://www.carlstalhood.com/vmware-horizon-8-rds-farms-pools/.

Navigation

This post applies to all Horizon versions 2006 (8.0) and newer.

Change Log

Non-Persistent – Instant Clones

All editions of Horizon 2006 and newer include Instant Clones so there is no need to use Composer. Composer is deprecated in Horizon 2006. Composer was removed from Horizon 2012 (8.1) and newer.

Notes on Instant Clones:

  • The master VM snapshot is copied to every LUN containing instant clones. Composer does the same.
  • If you deploy 12+ VMs per host of the same pool, then “Parent” machines are created on each ESXi host for each datastore. These “parent” machines are powered on and consume CPU/Memory/Disk resources. If you have six hosts and three datastores containing instant clones, then Horizon creates 18 parent virtual machines. Composer does not need parent virtual machines.
    • For lower density, Horizon 2006 and newer support Smart Provisioning, which eliminates the need for “Parent” machines. See the Smart Provisioning YouTube video for an overview.
    • Horizon 2306 (8.10) and newer now default to no longer creating parent virtual machines.
  • Horizon 2306 (8.10) and newer support Persistent Disks with dedicated Instant Clones. See Omnissa 93091 Guidelines for Persistent Disk Migration from Horizon 7 Environments to Horizon 8.
    • An alternative is Microsoft FSLogix, or App Volumes Writable Volumes
  • See Instant-Clone Desktop Pools at Omnissa Docs.

Infrastructure Prep

  • Instant Clones in Horizon 2303 and newer require vSphere 7 or newer. vSphere 6.7 and older will not work.
  • Each desktop pool points to one vSphere cluster.
  • Ensure vSwitch has sufficient ports for the new virtual desktops.
    • Instant Clones in Horizon 8.1 and newer support all port bindings, including ephemeral. Older versions of Horizon, including Horizon 7.x, require static port binding.
  • Ensure the VLAN has enough DHCP addresses for the desktop pool.
  • KMS Licensing is required, preferably using Active Directory-based activation – MAK licensing (Omnissa Docs) is not supported until Horizon 2212 and newer.
  • The virtual desktop pools will use the same hardware specs (e.g., vCPUs, memory size, network label, GPU) specified on the master virtual desktop. Adjust accordingly.
  • The master image should be in the same vSphere cluster where the instant clone virtual desktops will be created.
  • ESXi must be version 6 update 1 or newer
  • Master VM must be version hardware version 11 or newer
  • In Horizon Console, add Instant Clone Domain Accounts
  • In Horizon Console, enable View Storage Accelerator on your vCenter connection.
  • If you upgrade vCenter from version 6.5 or older to version 6.7 or later, then you must upgrade your ESXi hosts to version 6.7 or later at the same time. Afterwards, take a new snapshot of the master image and perform a push operation.
  • Windows 11 – Omnissa says don’t add vTPM to the gold image. Instead add the vTPM when creating the Instant Clone pool or Full Clone pool. There are various methods of installing Windows 11 without a vTPM. See Omnissa KB article 85960 Horizon and Horizon Cloud readiness for Microsoft Windows 11.
  • vTPM requires a Key Provider. vSphere 7 has a Native Key Provider that does not need any additional servers or licenses.
    1. In vSphere Client, in Inventory, click the vCenter object. On the right, on the Configure tab, scroll down to Key Providers and add a Native Key Provider.
    2. After it’s added, select it and then click Back-up to activate it.

Disk space

  • One or more LUNs (datastores) for storage of the virtual desktops.
  • By default, Replicas are copied to each LUN that contains virtual desktops.
    • It’s possible to place the Replica and the instant clones on separate LUNs. If you use a dedicated Replica LUN, then there is only one copy of the Replica no matter how many LUNs are used for storing virtual desktops.
    • Note: NFS VAAI requires the Replica to be copied to each virtual desktop LUN.
  • .vswp files – Plan for disk space for memory swap and graphics memory overhead. If the master virtual desktop has 4 GB of RAM configured and if none of its memory is reserved then each linked clone will have a 4 GB .vswp file.
    • To reduce the size of the .vswp files, edit each virtual desktop and reserve its memory. Whatever memory is reserved will be subtracted from the .vswp file size.
  • Instant Clone Delta disks – Delta disks start small whenever the virtual desktop boots and grow until the user logs off of the virtual desktop and it reboots.

Non-Persistent, Floating, Automatic, Instant Clone Desktop Pool

Master Image Preparation

Do the following on the master image that the virtual desktops will link to:

  1. Video Memory – shut down the master, Edit Settings (hardware) in vSphere client, expand Video card, and set video memory. More video memory means more client monitors. The maximum number of displays and maximum resolution of client monitors depends on the ESXi version, the Horizon version, and the Windows version with newest versions providing the greatest number of client monitors.
  2. DHCP – Make sure the master VM is configured for DHCP.
  3. Join domain – Join the master VM to the domain.
  4. Computer Group Policy – Make sure the Master VM is in the same OU as the Instant Clones so the Master VM will get the computer-level GPO settings. Run gpupdate on the master after moving the VM to the correct OU. New Instant Clones do not immediately refresh group policy so the group policy settings must already be applied to the master VM. See Omnissa 2150495 Computer-based Global Policy Objects (GPOs) that require a reboot to take effect are not applied on instant clones.
  5. KMS Licensing or Active Directory-Based Activation (recommended) is required.
  6. Snapshot – Shut down the master image and take a new snapshot.

Floating Pool

Use Horizon Console to create an Instant Clone pool:

  1. Login to Horizon Console.
  2. On the left, under Inventory, click Desktops.
  3. On the right, if you select an existing pool, you can click Duplicate to copy the settings to a new pool.
  4. On the right, click Add.
  5. In the Type page, select Automated desktop pool.
  6. In the vCenter Server page, select Instant Clone, select a vCenter server, and click Next. Notice that Composer is no longer an option.
  7. In the User Assignment page, select Floating, and click Next.
  8. In the Storage Optimization page, if you want to use storage tiering, check the box for Select separate datastores for replica and OS disk. Click Next.
  9. In the Desktop Pool Identification page, do the following:
    1. Give the pool a unique ID, which is not shown to the users. Horizon creates a vCenter VM folder with the same name as the Pool ID.
    2. Enter a Display name, which is shown to the users.
    3.  If you intend to use Omnissa Access, then leave Access group set to /. Otherwise, if you intend to delegate administration of this pool, then select an Access group that the delegated administrators have been assigned to.
  10. Click Next.
  11. In the Provisioning Settings page, do the following:
    • In Virtual Machine Naming, enter a Naming Pattern. You can use {n:fixed=3} to specify the location for incremented numerals in the machine names. Make sure the naming pattern does not conflict with any existing machines. Remember, the maximum computer name length is 15 characters.
      • Horizon 2103 (8.2) and newer let you Specify Names Manually instead of using a naming pattern.
    • In Desktop Pool Sizing, enter the maximum number of desktops to create. Ensure that the DHCP scope has enough addresses for the Max number of desktops specified here. If your desktop pool size exceeds a single VLAN, then you can create multiple pools and combine them into a Cloud Pod Global Entitlement.
    • Select Provision all machines up-front to create all of the machines now.
    • Or select Provision machines on demand, which tells Horizon to create the machines (up to the maximum) as users connect.
    • If you’re not creating all machines up-front, then specify the Number of spare (powered on) machines. As users connect, Horizon creates more machines to try to keep this number of spare machines running and waiting for a new connection.
  12. If Windows 11, consider checking the box to Add vTPM Device to VMs.
  13. Click Next.
  14. In the vCenter Settings page, most of these are self-explanatory. Click Browse next to each option and make your selection.

    • If the Golden Image VM (aka Parent VM or Master VM) is not showing up in the list, then check the box next to Show all parent VMs and click the … next to the VM to see the issue.
    • Instant Clones monitors/resolution – the number of monitors configured on the Master Image (snapshot) is displayed. If not correct, delete the snapshot, edit the master VM’s Hardware Settings, expand video card, make your desired changes, and take another snapshot.
    • Scroll down for more settings.
    • VM Folder Location – Horizon will create a folder under the location (e.g., datacenter) you choose. Make sure the folder names don’t have any spaces in them.
    • Datastores – select one or more datastores on which the virtual desktops will be placed.
    • If you selected to put Replica on a different datastore, then you’ll have another Browse button for Replica disk datastores.
    • When selecting Networks, you can use the Network from the parent image, or uncheck the box and select a different network.
  15. In Horizon 2206 and newer, in the VM Compute Profile Settings section, you can change the CPU, RAM, and Cores per socket assigned to each new virtual desktop.
  16. Click Next when done.
  17. In the Desktop Pool Settings page:
    1. You can select a Category Folder where the published icon will be placed on the client’s Start Menu and/or Desktop.

      1. Change the selection to Select a category folder from the folder list.
      2. You can type in a new category, or select an existing one.
      3. Then click Submit.
    2. In the Desktop Pool Settings page, Horizon Enterprise Edition lets you select a Session Type, which means you can optionally publish applications from virtual desktops.
    3. Change the selection for Logoff after disconnect to After, and specify a disconnect timer.

      • You can also use Group Policy to configure this. The GPO overrides the pool setting. Install the Horizon GPO Templates if you haven’t already. Edit a GPO that applies to the Horizon Agents. Find the Disconnect Session Time Limit (VDI) setting at VMware View Agent Configuration > Agent Configuration.
      • Horizon also has an Idle Time Until Disconnect (VDI) for virtual desktops. Note: RDSH idle timer is configured using Microsoft RDSH GPO settings, not Horizon GPO settings.
    4. You can allow users to restart their machines.
    5. If you choose Dedicated assignment instead of Floating assignment, there’s an option for Refresh OS disk after logoff. Leaving it set to Always is strongly recommended. The other options cause the delta disk to grow, and will cause data loss surprise for the users when you later push a new image. Instant Clones floating assignment pools always refresh on logoff.
    6. Reclaim VM disk space is also an option for Dedicated assignment pools. Floating assignment pools always refresh on logoff so there’s no need to reclaim disk space.
  18. Click Next.
  19. In the Remote Display Settings page:
    1. In 3D Renderer, there’s an option for NVIDIA GRID VGPU if you have GPUs installed.
    2. There’s an Allow Session Collaboration checkbox, which adds a VMware Horizon Collaboration icon in the system tray of the remote desktop, which lets you invite users to collaborate.  See Session Collaboration for details.
  20. Click Next.
  21. In the Guest Customization page,
    1. Next to AD container, click Browse, and select the OU where virtual desktop computer objects will be placed. You can type (paste) into the AD container field.
    2. Consider checking the box next to Allow reuse of pre-existing computer accounts.
  22. Click Next.
  23. In the Ready to Complete page, you may entitle users now, or leave it unchecked and do it later. Click Submit.

If you opted to add entitlements now:

  1. In the Add Entitlements window, click Add.
  2. Find a group that will have permission to log into these desktops, and click OK.
  3. Then click OK.

To check the status of the virtual desktops:

  1. Go to Inventory > Desktops.
  2. You might have to click the refresh icon on the top right to see the new pool.
  3. Click the link for the pool name.
  4. On the Summary page, if you scroll down, the vCenter Server section has a State field where you can see the status of the pool creation process.  It takes several minutes to publish the master image snapshot. After the snapshot is copied to the Replica, vSphere creates a digest file for View Storage Accelerator, which takes a few more minutes.
  5. Horizon Console has a Pending Image progress bar that doesn’t update automatically. To refresh it, scroll up and click the refresh icon.

  6. You can watch the progress in vSphere Client’s Recent Tasks list. In high-density pools, Instant Clones are forked from the cp-parent machine. In low-density pools, Instant Clones are cloned from the cp-replica.


  7. Eventually the pool’s tabs named Machines and Machines (InstantClone Details) will show the new machines.
  8. iccleanup.cmd can show you (list) the structure of the Instant Clones. For higher-density pools, there is a cp-parent at the bottom of the hierarchy. For Smart Provisioning of lower-density pools, there is no cp-parent.

If you wish to automate the creation of the pool, Aresh Sarkari at Automating Desktop Pool creation using PowerCLI – VMware Horizon 7.x explains New-HVPool -spec 'C:\temp\DesktopPool\LinkedClone.json' and the contents of the JSON file.

Entitle Virtual Desktops

To make a pool accessible by a user, it must be entitled.

  1. In Horizon Console, go to Inventory > Desktops.
  2. Click the link for a pool name.
  3. Switch to the Entitlements tab to see the existing entitlements.
  4. Click Add entitlements.
  5. In the Add Entitlements window, click Add.
  6. Find a group that will have permission to log into these desktops, and click OK.
  7. Then click OK.

Add Machine to Pool

  1. In Horizon Console, on the left, expand Inventory, and click Desktops.
  2. On the right, click the link for an existing Desktop Pool.
  3. At the top, click Edit.
  4. Switch to the Provisioning Settings tab, scroll down, and change the Max number of machines. Then click OK.
  5. With Instant Clones, this won’t take very long. In high-density pools, the new machine is forked from the cp-parent. In low-density pools, the new machine is cloned from the cp-replica.

  6. If you open the pool, the tabs named Machines and Machines (InstantClone Details) show the new machines.

Update a Pool

Master Image Preparation

  1. Power on the master/parent virtual desktop.
  2. After making your changes, shut down the master virtual desktop.
  3. Right-click the virtual machine and take snapshot. You must create a new snapshot.
  4. You’ll need to periodically delete the older snapshots. Right-click the master VM, and click Manage Snapshots.
  5. Delete one or more of the snapshots.
  6. In Horizon Console, go to Inventory > Desktops.
  7. Click the link for a pool name.
  8. On the Summary tab, click Maintain, and then click Schedule.
  9. In the Image page, select the new snapshot. Notice the snapshot’s monitor/resolution settings. Click Next.
  10. In the Scheduling page, decide when to apply this new image. If you select Force users to log off, notice you can customize the logoff message in Global Settings. Click Next.
  11. In the Ready to Complete page, click Finish.
  12. The pool’s Summary tab, near the bottom, indicates that the image is being pushed.

  13. You can click the tab named Machines (InstantClone Details) to check on the status of the push task. Notice the Pending Image.
  14. The snapshot is copied to each datastore.
  15. The snapshot is attached to a Replica, powered on, then powered off. Digest is then computed.
  16. Then the Replica is attached to a parent, and the parent is powered on. This all takes a bit of time. But the existing Instant Clones remain accessible until the Replica preparation is complete.
  17. Once Replicas are prepared, each machine is rebooted once.
  18. Eventually the Pending Image field will be cleared and the desktops are available again.

Host Maintenance – Instant Clones

Horizon 2012 (8.1) and newer have an option to Disable ParentVMs so vSphere Update Manager can put the hosts into maintenance mode. This uses the parentless Smart Provisioning technology. Find the option at Settings > Servers, select a vCenter server, click the More menu, and select Disable ParentVMs.

ESXi hosts running Instant Clones can be placed into maintenance mode without any special instructions.

Instant-Clone Maintenance Utilities at Omnissa Docs:

  • IcCleanup.cmd – use this utility to unprotect and delete some or all of the internal VMs created by instant clones. This is the easiest method of cleaning up Instant Clone internal machines.
  • IcUnprotect.cmd – use this utility to unprotect folders and VMs, delete VMs, and detect VMs whose master image or snapshot is deleted.
  • IcMaint.cmd – This command deletes the master images, which are the parent VMs in vCenter Server, from the ESXi host, so that the host can be put into maintenance mode. This utility generally isn’t needed. Also see Omnissa 2144808 Entering and exiting maintenance mode for an ESXi host that has Horizon instant clones.

Persistent Full Clones – Automated

Horizon can clone your Template machine to a specified number of Full Clones. Once Full Clones are created, you’ll need a Software Deployment tool, like Microsoft SCCM, to manage the Full Clones.

Customization Specification

Horizon uses a Customization Specification to specialize each machine cloned from the template:

  1. In vSphere Client, open the Menu and click Policies and Profiles.
  2. Make sure you have a Customization Specification with the settings detailed in the next few steps. You can create a new Customization Specification.
  3. In the Computer name page, set it to Use the virtual machine name.
  4. In the Windows license page, you can optionally set it to Include server license information but change it to Per seat.
  5. In the Network page, make sure the networks are set to DHCP. Once the machines are created you can manually set them to Static or configure DHCP reservations.
  6. In the Workgroup or domain page, enter credentials to join the new Full Clones to the domain.

Gold Image Template

  1. On the gold image machine, in sysdm.cpl > Advanced > User Profiles > Settings, make sure there are no local profiles other than your administrator profile and the Default Profile. Delete all others. Sysprep frequently fails if there is more than one profile on the template.
  2. If you have SCCM Client installed on your Gold Image, then see Prepare the client computer for imaging.
  3. Shut down the Gold Image.
  4. Right-click the gold image, expand Template, and then click Convert to Template.
  5. Before creating a pool, test deploying a new machine from the template to make sure SysPrep is successful.
    1. Right-click the Template and click New VM from This Template.
    2. In the Select clone options page, check the boxes next to Customize the operating system and Power on virtual machine after creation.
    3. In the Customize guest OS page, select the Customization Specification you created earlier.
    4. If cloning fails, then see Broadcom 2001932 Locations of sysprep log files. Store apps (aka UWP apps) are a frequent cause of SysPrep failures. You can convert your Template back to a Virtual Machine, power it on, fix the problem, power it off, and then convert it to a Template again.

Automated Full Clone Pool

  1. In Horizon Console, in the left menu, expand Inventory and then click Desktops.
  2. On the right, click Add.
  3. In the Type page, select Automated Desktop Pool and click Next.
  4. In the vCenter Server page, select Full Virtual Machines. Select your vCenter Server and then click Next.
  5. In the User Assignment page, you usually want Dedicated assignment.
  6. Automatic Assignment is an optional feature that avoids you having to manually assign users to each full clone desktop. But manual assignments give you more control over capacity planning. Click Next.
  7. In the Storage Optimization page, click Next.
  8. In the Desktop Pool Identification page, give the pool an ID (no spaces) and a Display Name that is shown to users. Horizon creates a vCenter virtual machine folder with the same name as the ID. Click Next.
  9. In the Provisioning Settings page, specify a Naming Pattern. You can hover your mouse over the information icon to see the syntax. Then scroll down.
  10. After scrolling down, specify the number of machines to create. If you specify All Machines Up-Front, then Horizon will create the Maximum Machines. If you specify Spare (Powered On) Machines, then Horizon will try to preserve this specified number of unassigned machines. Click Next.
  11. In the vCenter Settings page, click Browse next to Template and select the template you created earlier.
  12. Click Browse next to the other fields and specify where you want the new machines to be created. Make sure VM Folder Location doesn’t have any spaces in it. Click Next.
  13. In the Desktop Pool Settings page, these settings are the same as Instant Clones, but Remote Machine Power Policy might be different. Scroll down.
  14. After scrolling down, notice the option for Show Assigned Machine Name instead of the pool name. Hover your mouse over the information icons. Click Next when done.
  15. In the Remote Display Settings page, specify video settings and then click Next. Horizon 2106 (8.3) and newer let you choose 5K and 8K monitors for Blast only.
  16. In the Advanced Storage Options page, note that View Storage Accelerator is just a read cache (no write caching). If your storage can handle the reads then enabling this feature probably isn’t necessary. Click Next.
  17. In the Guest Customization page, select the Customization Specification that you created earlier. Consider checking the box next to Allow Reuse of Existing Computer Accounts.
  18. Horizon 2212 (8.8) and newer let you specify the OU for the new machines. Otherwise, they are created in the Computers container unless you pre-create the computer accounts in your desired OU. Click Next.

  19. In the Ready to Complete page, you can optionally Entitle users After Adding Pool. Click Submit. Note: users must both be entitled to the pool and assigned to an individual machine.

Machine Administration

  1. Cloning progress – Use vSphere Client Recent Tasks to watch the progress of the cloning. It will take time for the cloning to complete plus time for SysPrep to complete.
  2. If you click the Pool name link and then switch to the Machines tab, you should eventually see the new machines.
  3. Assign User to Machine – You can select a machine, click the drop-down for More Commands, and then Assign User.
  4. Machine alias – By default, the pool’s Display name is displayed to each user. You can instead change it to the individual Machine Name, or to an administrator-specified machine alias.
    1. Go to the pool’s Summary tab and click Edit.
    2. Switch to the tab named Desktop Pool Settings.
    3. Scroll down and find the checkboxes for Show Assigned Machine Name and Show Machine Alias Name. If you select Alias Name, then an additional command appears on the Machines page.
    4. After editing the pool and enabling Show Machine Alias Name, On the Machines tab, select a machine, and then click the drop-down for Update Machine Aliases. The Alias is shown to the user instead of the pool’s Display Name or the actual machine name.
  5. Add Machines – To create more Full Clone machines from the same template:
    1. Click the name (link) of the pool.
    2. On the Summary tab, click Edit.
    3. On the Provisioning Settings tab, scroll down and enter a larger Maximum Machines.

  6. Update Template – If you plan to create more Full Clone machines in the next few months, then you should update your Template by converting it to a virtual machine, update the virtual machine, and then convert it back to a Template. Note that the updated Template only applies to new Full Clones and has no effect on existing Full Clones. To update existing Full Clones, use a Software Deployment tool like Microsoft SCCM.

Virtual Hardware

Omnissa Tech Zone Manually Creating Optimized Windows Images for Horizon VMs

  1. The virtual desktop pools will use the same hardware specs (e.g., vCPUs, memory size, network label) specified on the master virtual desktop. Adjust accordingly.
  2. For New Hard disk, consider setting Thin provision.
  3. Make sure the virtual desktop is using a SCSI controller.
  4. The master virtual desktop should be configured with a VMXNET 3 network adapter.
  5. When building the master virtual desktop, you will probably boot from an ISO.
  6. Before using Horizon Console to create a pool based off of this master image, ensure the CD/DVD drive points to Client Device and is not Connected. The important part is to make sure that ISO file is not configured.
  7. There’s no need for the Floppy drive so remove it.
  8. If you have any Serial ports, remove them.

Windows

Omnissa TechZone Manually Creating Optimized Windows Images for Horizon VMs

Preparation

  • Windows 11 Versions – Windows 11 is supported with Horizon 2111 (8.4) and newer.
    • Windows 11 22H2 is supported with Horizon Agent 2209 (8.7) and DEM Agent 2209 (10.7) and newer.
    • Omnissa says don’t add vTPM to the gold image. Instead add the vTPM when creating the Instant Clone pool or Full Clone pool. There are various methods of installing Windows 11 without a vTPM. See Omnissa KB article 85960 VMware Horizon and Horizon Cloud readiness for Microsoft Windows 11.
    • vTPM requires a Key Provider. vSphere 7 and newer have a Native Key Provider that does not need any additional servers or licenses.
      1. In vSphere Client, in Inventory, click the vCenter object. On the right, on the Configure tab, scroll down to Key Providers and add a Native Key Provider.
      2. After it’s added, select it and then click Back-up to activate it.

  • Windows 10 Versions
  • VMware Tools. Install the latest version of VMware Tools and Guest Introspection (formerly known as vShield Endpoint) Driver prior to installing the Horizon Agent.
  • For the AppVolumes Agent and Imprivata OneSign agent (if applicable), don’t install them until Horizon Agent is installed.

Power Options

  1. Run Power Options. Right-click the Start Menu to access Power Options.
  2. Click Additional power settings.
  3. Select Ultimate Performance, or click the arrow to show more plans, and select High performance.
  4. Next to the power plan, click Change plan settings.
  5. Change the selection for Turn off the display to Never and click Save changes.
  6. You can also configure these setting using group policy.

System Settings

  1. Domain Join. Use sysdm.cpl to join the machine to the domain. Also see Omnissa 2150495 Computer-based Global Policy Objects (GPOs) that require reboot are not applied on instant clones.
  2. In System control panel applet (sysdm.cpl), on the Remote tab, enable Remote Desktop.
  3. Activate Windows with a KMS license if not already activated. Note: only KMS is supported with Instant Clones.

Install Applications

Install applications locally if you want them to be available on all virtual desktops created based on this master virtual desktop.

Or you can use a Layering product (e.g. Omnissa App Volumes, Microsoft MSI-X App Attach, Liquidware FlexApp) or App Streaming (e.g. ThinApp, Microsoft App-V). Note: logins are fastest if apps are installed in the master image. All app layering/streaming technologies introduce a logon delay. You can use Microsoft FSLogix App Masking to hide applications and Start Menu shortcuts that users should not see.

Antivirus

Omnissa Tech Zone Antivirus Considerations in a Horizon Environment contains exclusions for Horizon, App Volumes, Dynamic Environment Manager, ThinApp, etc.

Horizon Agent

Horizon Agent Installation/Upgrade

Install Horizon Agent on the master virtual desktop. Upgrades are performed in-place.

  1. Latency – In Horizon 2111 (8.4) and newer, maximum latency between the Horizon Agent machine and Connection Server is 120ms. Older versions of Horizon have lower maximum latencies.
  2. VMware Tools – Only install Horizon Agent after you install VMware Tools.
    1. The latest versions of VMware Tools resolve security vulnerabilities.
    2. If you need to update VMware Tools, uninstall Horizon Agent, upgrade VMware Tools, and then reinstall Horizon Agent.
    3. See Omnissa Product Interoperability Matrices for supported versions of VMware Tools with different versions of Horizon Agent.
  3. Horizon 2406 (8.13) is the latest version.
  4. Horizon 2312.1 (8.12.1) is an Extended Service Branch, which is supported for three years from its January 2024 release date.
  5. Horizon 2212 (8.8) is an Extended Service Branch, which is supported for three years from its January 2023 release date. The Agent was not updated for version 8.8.1.
  6. Download Horizon Agent 2406 (8.13) ESB, or Horizon Agent 2312.1 (8.12) ESB.

  7. Run the downloaded VMware-Horizon-Agent-x86_64-2406-8.13.0.exe.
  8. If you want the URL Content Redirection feature, then you must run the Agent installer with the following switches: /v URL_FILTERING_ENABLED=1
  9. If you want the UNC Path Redirection feature in 8.7 and newer, then you must run the Agent installer with the following switches: /v ENABLE_UNC_REDIRECTION=1. You can combine the two switches.
  10. In the Welcome to the Installation Wizard for VMware Horizon Agent page, click Next.
  11. In the Network protocol configuration page, select IPv4, and click Next.
  12. In the Custom Setup page, there are several features not enabled by default. Horizon Smart Policies in Dynamic Environment Manager (DEM) can control some of these features but only if the features are installed.
    1. If you want USB Redirection, then enable that feature.
    2. Horizon Agent 2006 (8.0) and newer does not include Persona.
    3. If you want Scanner Redirection, then enable that feature. Note: Scanner Redirection will impact host density.
    4. Horizon Performance Tracker adds a program to the Agent that can show the user performance of the remote session. You can publish the Tracker.

    5. Horizon 2006 (8.0) and newer no longer include ThinPrint (aka Virtual Printing). VMware Integrated Printing is the replacement for ThinPrint and requires Horizon Client 4.10 or newer.
    6. In Horizon 2206 and newer, Storage Drive Redirection provides faster performance than Client Drive Redirection.
  13. Click Next when done making selections.
  14. If you see the Remote Desktop Protocol Configuration screen, then select Enable and click Next.

  17. Click Yes when asked to restart.
  18. If you want to know what features were selected during installation, look in HKLM\Software\VMware, Inc.\Installer\Features_HorizonAgent. Or look in the installation log files as detailed at Paul Grevink View Agent, what is installed?

  19. To verify installation of the URL Content Redirection feature, check for the presence of C:\Program Files\VMware\VMware View\Agent\bin\UrlRedirection.
  20. There’s also an IE add-on.
  21. URL Content Redirection is configured using group policy.
  22. To verify installation of the UNC Content Redirection feature, check for the presence of C:\Program Files\VMware\VMware View\Agent\bin\UncRedirection.

Install/Upgrade Dynamic Environment Manager (DEM) Agent

All editions of Horizon 2006 (8.0) and newer are entitled to Dynamic Environment Management (DEM).

  • Horizon Standard Edition and Horizon Advanced Edition are entitled to DEM Standard Edition, which only has personalization features that replace Persona. If you are using FSLogix Profile Containers for profiles, then you probably don’t need DEM Standard Edition.
  • Horizon Enterprise Edition is entitled to DEM Enterprise Edition, which has all DEM features, including Smart Policies, Privilege Elevation, etc.

DEM 2006 and newer Agents (FlexEngines) require additional configuration to enable DEM Computer Settings. You can either configure registry settings on each DEM Agent machine, or in DEM Agent 2103 and newer you can use an installer command-line switch. Both are detailed at Perform Installation with Computer Environment Settings Support at Omnissa Docs.

  • Group Policy Preferences can push these registry keys to the Horizon Agent machines. Or you can manually modify the registry in your master images. The minimum registry values are Enabled and ConfigFilePath as detailed at Perform Installation with Computer Environment Settings Support at Omnissa Docs. For the list of additional registry values, see FlexEngine Configuration for Computer Environment Settings at Omnissa Docs.
  • Command line install looks something like below. The command line installer switch sets the same ConfigFilePath and Enabled registry values as shown above. 
    msiexec /i "\\fs01\bin\VMware\DEM\VMware-DEM-Enterprise-2406-10.13-GA\VMware Dynamic Environment Manager Enterprise 2406 10.13 x64.msi" /qn COMPENVCONFIGFILEPATH=\\fs01\DEMConfig\general

To install DEM Agent:

  1. Windows 10 Compatibility – See VMware 57386 VMware Dynamic Environment Manager and Windows 10 Versions Support Matrix
  2. Make sure Prevent access to registry editing tools is not enabled in any GPO since this setting prevents the FlexEngine from operating properly.
  3. DEM 2406 (10.13) is the latest release.
    1. Horizon 2312 (8.12) ESB release comes with DEM 2312 (10.12).
    2. Horizon 2212 (8.8) ESB release comes with DEM 2212 (10.8).
  4. Based on your entitlement, download either DEM 2406 (10.13) Enterprise Edition, or DEM 2406 (10.13) Standard Edition. For ESB Horizon, download the DEM version included with your ESB version of Horizon.

  5. Run the extracted VMware Dynamic Environment Manager Enterprise 2406 10.13 x64.msi.
  6. In the Welcome to the VMware Dynamic Environment Manager Enterprise Setup Wizard page, check the box next to I accept and click Next.
  7. In the Destination Folder page, click Next.
  8. In Choose Setup Type page, click Custom.
  9. In the Custom Setup page, click Next. Note: the DEM Management Console is typically installed on an administrator’s machine.
  10. In DEM 2111 and older, in the Choose License File page, if installing on a Horizon Agent, then no license file is needed. DEM 2203 and newer no longer ask for licenses since DEM Console installs the DEM license in the DEM Configuration Share. Click Next.
  11. In the Ready to install VMware Dynamic Environment Manager Enterprise page, click Install.
  12. In the Completed the VMware Dynamic Environment Manager Enterprise Setup Wizard page, click Finish.
  13. If you have PCoIP Zero Clients that map USB devices (e.g. USB drives), then you might have to set the following registry value:
    • HKLM\Software\VMware, Inc.\VMware VDM\Agent\USB
      • UemFlags (DWORD) = 1
  14. DEM is enabled using Group Policy and configured using the DEM Management Console.

Logon Monitoring

See Omnissa 93158 Information about changes in logon timing data format in Horizon form Horizon 8 2111 and Later.

By default, in services.msc, the VMware Horizon View Logon Monitor service is not running. Set it to Automatic and start it.

The logon logs are stored at C:\programdata\VMware\VMware Logon Monitor\Logs on each Horizon Agent.

Inside each session log file are logon time statistics.

Unity Touch

With the Unity Touch feature, tablet and smart phone users can quickly navigate to a Horizon View desktop application or file from a Unity Touch sidebar. Although end users can specify which favorite applications appear in the sidebar, for added convenience, administrators can configure a default list of favorite applications.

In the Unity Touch sidebar, the favorite applications and favorite files that users specify are stored in the user’s profile. For non-persistent pools, enable Roaming Profiles.

To set the default list of favorite applications:

  1. Navigate to HKLM\Software\Wow6432Node\VMware, Inc.\VMware Unity
  2. Create a string value called FavAppList.
  3. Specify the default favorite applications using format: path-to-app-1|path-to-app-2|path-to-app-3|…. For example:
Programs/Accessories/Accessibility/Speech Recognition.lnk|Programs/VMware/VMware vSphere Client.lnk|Programs/Microsoft Office/Microsoft Office 2010 Tools/Microsoft Office 2010 Language Preferences.lnk

Unity Touch can be disabled by setting HKEY_LOCAL_MACHINE\Software\VMware,Inc.\VMware Unity\enabled to 0.

For more information, see Configure Favorite Applications Displayed by Unity Touch at Omnissa Docs.

ClonePrep – Rearm

By default, when Horizon creates Instant Clones, one of the tasks that ClonePrep performs is to rearm licensing. You can prevent rearm by setting the following registry key:

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vmware-viewcomposer-ga
    • SkipLicenseActivation  (DWORD) = 0x1

Dynamic PCoIP Policies

If you wish to change PCoIP Policies (e.g., clipboard redirection, client printers, etc.) based on how the user connects, see Managing VMware Horizon View Secret Weapon with Puppet Enterprise. The article describes using Puppet to change PCoIP settings. You can also configure VMware Horizon View Script Host service to run a script to change PCoIP configuration based on the Connection Server that the user connected through.

Microsoft FSLogix

Why FSLogix?

Microsoft FSLogix has two major features:

  • Profile Container is an alternative to DEM Personalization.
  • App Masking is an alternative to App Volumes.

DEM has three categories of features: Personalization, User Settings, and Computer Settings. FSLogix Profile Container only replaces the Personalization feature set. You typically do FSLogix Profile Container for profiles and use DEM for User Settings and Computer Settings. Here are some advantages of FSLogix Profile Container over DEM Personalization:

  • FSLogix Profile Container saves the entire profile but DEM Personalization requires you to specify each setting location that you want to save. FSLogix is “set and forget” while DEM Personalization requires tweaking for each application.
  • At logon, DEM Personalization must download and unzip each application’s profile settings, which takes time. FSLogix simply mounts the user’s profile disk, which is faster than DEM Personalization.
  • FSLogix Profile Container has special support for roaming caches and search indexes produced by Microsoft Office products (e.g. Outlook .ost file).
  • FSLogix is owned, developed and supported by Microsoft.

Here are some FSLogix Challenges as compared to DEM Personalization:

  • FSLogix Profile disk consumes significant disk space. The default maximum size for a FSLogix profile disk is 30 GB per user.
  • High Availability for FSLogix Profile disks file share is challenging. The file server High Availability capability must be able to handle .vhdx files that are always open. DFS Replication is not an acceptable HA solution. One option is Microsoft Scale Out File Server (SOFS) cluster. Another option is Nutanix Files.

Omnissa App Volumes has some drawbacks, including the following:

  • Completely separate infrastructure that must be built, maintained, and troubleshooted.
  • Introduces delays during logon as AppStacks are mounted.
  • AppStacks can sometimes conflict with the base image or other AppStacks.

An alternative approach is to install all apps on the base image and use FSLogix App Masking to hide unauthorized apps from unauthorized users. No delays during logon.

Microsoft FSLogix is free for all Microsoft RDS CALs, Microsoft Virtual Desktop Access per-user CALs, and all Microsoft Enterprise E3/E5 per-user licenses. Notice that per-device licenses are excluded. See Eligibility Requirements at Microsoft Docs.

FSLogix Installation

Do the following to install Microsoft FSLogix on the Horizon Agent machine:

  1. Go to https://docs.microsoft.com/en-us/fslogix/install-ht and click the download link.
  2. Extract the downloaded .zip file.
  3. In the FSLogix \x64\Release folder, run FSLogixAppsSetup.exe.
  4. Check the box next to I agree to the license terms and conditions and click Install.
  5. In the Setup Successful page, click Restart.
  6. Make sure the Windows Search service is set to Automatic and Running.
  7. If Office is already installed, then repair the Office installation after installing and starting the Windows Search Service.

FSLogix is configured through Group Policy or by editing registry values on each FSLogix Agent machine.

Windows OS Optimization Tool

  1. See Windows OS Optimization Tool for Horizon Guide at Omnissa Tech Zone for details on this tool.
  2. Download the Windows OS Optimization Tool. Versions 1.2 and newer support Windows 11 22H2.
  3. Run VMwareOSOptimizationTool-x86_64.exe.
  4. On the Optimize tab, choose a template.
  5. Then click Analyze on the bottom of the window.
  6. Near the top of the window click the Common Options button and make your selections on each of the pages. Click OK when done.

  7. The top right box named Analysis Summary shows the number of optimizations not yet applied.
  8. Review the optimizations and make changes as desired. Then on the bottom right, click Optimize.
  9. The History tab lets you rollback the optimizations.
  10. The Finalize tab contains tasks that should be run every time you seal your parent image.
  11. The Update tab lets you re-enable Windows Update so you can update the parent image.

Additional Optimizations

Additional Windows 10 Optimizations

Snapshot

  1. Make sure the master virtual desktop is configured for DHCP.
  2. If connected to the console, run ipconfig /release.
  3. Run antivirus sealing tasks. For example:
  4. Base Image Script Framework (BIS-F) automates many image sealing tasks. The script is configurable using Group Policy.

  5. Shutdown the master virtual desktop.
  6. Edit the Settings of the master virtual machine and disconnect the CD-ROM. Make sure no ISO is configured in the virtual machine.
  7. Take a snapshot of the master virtual desktop. Instant Clones requires a snapshot.

The URL entered in the browser must either be https://127.0.0.1/admin, or the Secure Tunnel URL (Horizon Console > Settings > Servers > Connection Servers tab > Edit). By default, the Secure Tunnel URL is the FQDN of the Connection Server.

If you don’t use one of these URLs then you’ll see a Login Failed message.

If you want to use a different URL than the Secure Tunnel URL (e.g., short name instead of FQDN, or load balanced name instead of server name), then go to C:\Program Files\VMware\VMware View\Server\sslgateway\conf, edit or create locked.properties file, and enter the following:

allowUnexpectedHost=true
checkOrigin=false
enableCORS=false

More details at Omnissa 2144768 Accessing the Horizon View Administrator page displays a blank error window in Horizon and 85801 Cross-Origin Resource Sharing (CORS) with Horizon 8 and loadbalanced HTML5 access. allowUnexpectedHost defaults to false in Horizon 2306 and Horizon 2212.1 and newer. Another option is to add portalHost entries as detailed at Allow HTML Access Through a Gateway at Omnissa Docs.

Licensing

Horizon Licenses are available either as product keys or as cloud subscription licenses. For cloud subscription licenses, Horizon 2406 and newer can activate the license without needing an Edge Gateway. For older versions of Horizon, download the Edge Gateway from the Horizon Cloud next-gen control plane and connect it to a Connection Server. See Deploying a Horizon Edge Gateway for Horizon 8 Environments at Omnissa Tech Zone.

In the Horizon Console:

  1. Open Horizon Console.
  2. Login using a Horizon administrator account.
  3. On the left, expand Settings and click Product Licensing and Usage.
  4. You’ll be asked to activate SaaS or Term/Perpetual license. Term and Perpetual are license keys.
  5. If SaaS subscription, then login to Horizon Cloud and complete the wizard.
  6. If Term or Perpetual, then enter your license key.
  7. If Term or Perpetual, then licensing information is displayed:
    • License expiration is shown.
    • Instant Clones are available in all editions.
    • Application Remoting (published applications) requires Horizon Advanced Edition.
    • Teams Optimization requires Horizon Advanced Edition.

Horizon Administrators

To configure Horizon Administrators:

  1. In Horizon Console, expand Settings, and click Administrators.
  2. On the right, near the top, click Add User or Group.
  3. In the Select administrators or groups page, click Add.
  4. Enter the name of a group that you want to grant Horizon Administrator permissions to, and click Find.
  5. After the group is found, check the box next to the group (or highlight the group), and then click OK.
  6. Continue adding groups, or just click Next.
    Note: This wizard only lets you select one role; so, only add groups that will have the same role assigned. You can run the wizard multiple times.
  7. In the Select a role page, select the role (e.g. Administrators or Help Desk Administrators, which grants access to the Help Desk tool). Then click Next.
  8. Select an Access Group to which the permission will be applied and then click Finish.
    • Access Groups let you designate permissions to specific pools instead of to all pools.
    • Federation Access Groups are available in Horizon 2103 (8.2) and newer and let you restrict admin permissions to specific Global Entitlements (Cloud Pod Architecture).
    • In Horizon 2206 and newer, Help Desk role can be assigned to Access Groups.

Help Desk Website

Horizon has a web-based Help Desk tool built into Horizon Connection Server.

  • In Horizon Console, simply enter a user name in the search box at the top of the page.

The Desktops and Applications tabs let you see what the user is entitled to. You can even export these lists.

On the Sessions tab, click a session to see more details.

On the Details tab, scroll down to find action buttons like Remote Assistance. These buttons are kind of hidden.

Keep scrolling down and you’ll see Logon Segments.

The Processes tab lets you end processes in the user’s session.

Notes on the Help Desk feature:

  • Enterprise Licensing – Help Desk tool requires Horizon Enterprise edition license, or Horizon Apps Advanced edition license. Horizon Standard Edition licenses do not include this tool. The Product Licensing page indicates if Help Desk is licensed or not.
  • Horizon has a built-in Help Desk Administrators role that enables members to use the Help Desk tool.

    • Add Help Desk users to the Administrators and Groups tab, and assign them one of the Help Desk roles.
  • 15 minutes of History – There’s only 15 minutes of collected metric data.

See Using Horizon Help Desk Tool in Horizon Console at Omnissa Docs.

vCenter Connection

Horizon must connect to vCenter for several reasons:

  • Power manage the virtual machines
  • Create new virtual machines using Instant Clones
  • Update virtual machines using Instant Clones

See the Product Interoperability Matrix for supported vCenter versions.

If you are adding multiple vCenter servers to Horizon, make sure each vCenter Server has a Unique ID. In vSphere Client, go to the vCenter Server > Configure > Settings > General > Edit > Runtime Settings, and confirm that the ID is unique for each vCenter server.

To add the vCenter connection:

  1. In Horizon Console expand Settings, and click Servers.
  2. In the right pane, in the vCenter Servers tab, click Add.
  3. In the VC Information page, do the following:
    1. In the Server address field, enter the FQDN of the vCenter server.
    2. In the User Name field, enter the previously created Active Directory account (domainname\username) that Horizon will use to login to vCenter.
    3. Also enter the service account’s password.
    4. Horizon 2106 (8.3) and newer have a Deployment Type drop-down. If on-premises, leave it set to General.
  4. Click Next.
  5. If you see a message regarding invalid certificate, click View Certificate. Then click Accept.

  6. In Horizon 2012 and newer, View Composer is no longer an option.
    1. In Horizon 2006, in the View Composer page, select Do not use View Composer. There’s no need to use Composer since all editions of Horizon 2006 and newer include Instant Clones. Click Next.
  7. In the Storage page, do the following:
    1. Reclaim VM disk space requires IOPS during its operation. It’s only useful for the rare persistent Instant Clones use case and thus is generally unchecked.
    2. Check the box to Enable View Storage Accelerator and increase the host cache size up to 32768. Notes:
      • View Storage Accelerator is required for Instant Clones replica disks.
      • The cache size value is removed from RAM and that RAM is no longer accessible to virtual machines.
      • Higher host cache sizes should speed up Instant Clone Smart Provisioning (without parent image).
  8. Click Next.
  9. In the Ready to Complete page, click Submit.

Instant Clone Domain Accounts

If you plan to use Instant-Clone to create non-persistent virtual desktops, then add an administrator account that can join machines to the domain.

  1. In Horizon Console 2012 and newer, on the left expand Settings, and click Domains.

    1. In Horizon Console 2006, on the left, expand Settings and click Instant Clone Domain Accounts.
  2. On the right, the Connection Server tab shows the domains that the Connection Servers see.
  3. On the tab named Instant Clone Engine Domain Accounts, click Add.
  4. Select the domain.
  5. Enter credentials of a service account that can join machines to the domain. Click OK.

Restrict Remote Access

The Users and Groups node has a Remote Access tab. If you add groups or users to this tab, then only these groups and users can login through Unified Access Gateway (UAG).

Users not in the list can’t login through Unified Access Gateway (UAG).

Disable Secure Tunnel

By default, internal Horizon Clients connect to Horizon Agents by tunneling (proxying) Blast or PCoIP through a Horizon Connection Server. It would be more efficient if the internal Horizon Clients connect directly to the Horizon Agents instead of going through a Connection Server.

  • If the tunnels are enabled, and if you reboot the Connection Server, then user connections will drop.
  • If the tunnels are disabled, then rebooting the Connection Server will not affect existing connections.

To disable the tunnels:

  1. In Horizon Console, on the left, expand Settings, and click Servers.
  2. On the right, switch to the Connection Servers tab.
  3. Click the Connection Server to highlight it, and click Edit.
  4. On the General tab, uncheck the boxes next to HTTP(S) Secure Tunnel and the PCoIP Secure Gateway.
  5. For Blast Secure Gateway, change it to Use Blast Secure Gateway for only HTML Access connections to machine. Click OK.

Event Database and Syslog

To add the Events Database:

  1. In Horizon Console, on the left, expand Settings and click Event Configuration.
  2. On the right, under Event Database, click Edit.
  3. In the Edit Event Database dialog box, do the following:
    1. Enter the name of the SQL server.
    2. Select Microsoft SQL Server as the Database type. Note: Horizon 2103 (8.2) and newer have an option for PostgreSQL.
    3. Enter the name of the database.
    4. Enter the SQL account credentials (no Windows authentication).
    5. Optionally, enter HE_ (or similar) for the Table prefix. This allows you to use the same Events database for multiple Horizon installations.
  4. Click OK.
  5. Horizon 2106 (8.3) and newer support SSL to the events database. See SSL Connection to Event Database at Omnissa Docs.
  6. On the right, in the Event Settings section, you can click Edit to change the age of events shown in Horizon Console or Horizon Administrator.
  7. To add a Syslog server, look on the right side of the page.
  8. There are configuration options for logging to a file (Events to File System).
  9. You can go to Monitor > Events to view the events in the database.

Event Queries

Omnissa utility – Horizon View Event Notifier: collects and sends the alerts via email (SMTP) to users that are specified during the configuration process. It allows aggregation of alerts across multiple Horizon View Pods and for near real-time alerting of Horizon View alerts that are otherwise very difficult to be notified on.

Chris Halstead – Horizon View Events Database Export Utility: this utility allows administrators to easily apply very detailed filtering to the data and export it to .csv. You can filter on time range,  event severity, event source, session type (Application or Desktop), Usernames and Event Types.  The application allows for extremely granular export of data.   The exported columns can also be customized and the application will export data from both the live and the historical tables in the View Events Database.

To retrieve the top 50 maximum number of concurrent desktop sessions over a period time from the event_historical table, run this query:

select Count, Time from(select top 50 DOB.<prefix>_data_historical.IntValue as 'Count', DOB.<prefix>_historical.Time as 'Time' from DOB.<prefix>_historical.DOB.<prefix>_data_historical where DOB.<prefix>_historical.EventID = DOB.<prefix>_data_historical.EventID and DOB.<prefix>_data_historical.Name = 'UserCount' and DOB.<prefix>_historical.EventType='BROKER_DAILY_MAX_DESKTOP order by DOB.<prefix>_historical.Time DESC) A Order by Time

Where <prefix> is the prefix for the event table. You can find the prefix that you must use by examining other view definitions, such as user_events.

Global Settings

  1. In Horizon Console, on the left, expand Settings and click Global Settings.
  2. On the right, under Global Settings, in the General Settings tab, click Edit.
  3. Set the Horizon Console session timeout. 4320 minutes (72 hours) is the maximum.
  4. Forcibly disconnect users is an active session timeout. It is not an idle timeout in that it doesn’t care if the user is working or not. The default is 10 hours so consider increasing it. Note: this timer does not log the user out of Windows. Instead it merely disconnects the user and requires the user to logon to Horizon Connection Server again.

    • Horizon 2206 and newer let you configure messages shown to users before the forcible timeout occurs.
  5. Under Client-dependent settings you can set an idle timeout. This is a disconnect, not logoff.

    • In a pool’s Desktop Pool Settings, you can configure Log Off After Disconnect.
  6. Other methods of configuring an idle timeout for desktop sessions:
  7. Enable automatic status updates enables automatic updating of the table displayed in the top-left corner of Horizon Console.
  8. The Send domain list option is unchecked by default, which means users must enter a domain name instead of picking one from a list. Check this box (and uncheck Hide domain list) to restore functionality from Horizon 7.7 and earlier. See VMware Blog Post Changes in Logon for VMware Horizon.
  9. Make other changes as desired. Click OK when done.
  10. Horizon 2306 (8.10) and newer let you restrict which versions of Horizon Agent that users can connect to. Find it at Settings > Global Settings > Horizon Agent Restrictions.

Log On as Current User is also disabled by default. To enable this client feature:

  1. In Horizon Console, on the left, expand Settings, and click Servers.
  2. On the right, switch to the Connection Servers tab.
  3. Highlight a Connection Server and click Edit.
  4. Switch to the Authentication tab.
  5. Scroll down. Check the box next to Accept logon as current user. Click OK.

Client Version Restrictions

Horizon can restrict connections to a minimum version of Horizon Client.

  1. In Horizon Console, on the left, expand Settings, and click Global Settings.
  2. On the right, switch to the tab named Client Restriction Settings.
  3. Click Edit.
  4. For each client type, enter a minimum version number. Additional options are available if you scroll down.
  5. Block Additional Clients blocks all clients other than the ones you selected. One use case is to block HTML Access.
  6. You can customize the message that users see if their client is too old. This feature requires Horizon Client 2006 (aka 8.0) or newer.
  7. Click OK when done.
  8. The client version is enforced when you try to launch an icon.

Global Policies

By default, Multimedia Redirection is disabled. You can enable it in Global Policies.

  1. In Horizon Console, go to Settings > Global Policies.
  2. On the right, click Edit Policies.
  3. Set Multimedia redirection (MMR) to Allow, and click OK. Notice that Multimedia redirection is not encrypted.

Backups

Connection Server LDAP Backup can be configured in Horizon Console.

  1. in Horizon Console, on the left, expand Settings and click Servers.
  2. On the right, switch to the Connection Servers tab.
  3. Select a Horizon Connection Server, and click Backup Now. Backups can be found in C:\ProgramData\VMware\VDM\backups.
  4. To change automatic backup settings, Edit the Horizon Connection Server, and switch to the Backup tab.
  5. You can schedule automatic backups. See Omnissa 1008046 Performing an end-to-end backup and restore for Horizon.

Horizon Connection Server Certificate

Horizon Console Certificate Management

Horizon 2212 and newer have a Certificate Management section in the Horizon Console under Settings. Horizon 2312 and newer can manage cluster certificates in addition to machine certificates.

    1. The Administrators role in Horizon does not include the Certificate Management permission. Go to Settings > Administrators. On the right, switch to the tab named Role Privileges. Click Add.
    2. Name the role CertificateManagement or similar. Select the Manage Certificates privilege, which might be on page 2. Click OK.
    3. Switch to the tab named Administrators and Groups. Select your Horizon Admins group and click Add Permissions.
    4. Select your new CertificateManagement role and click Finish.
    5. If you log out, log back in, and then go to Settings > Certificate Management, the buttons should no longer be grayed out. You can either import an existing cert, or click Generate CSR to create a new cert. If you click Generate CSR, then there’s no way to use this interface to combine the signed certificate with the key, so it’s probably better to use some other method of creating a certificate and export it as a .pfx file.
    6. Click Import to upload a PFX file to the Connection Server that you are currently connected to. For Machine Identity, you’ll have to repeat this process on each Connection Server.
    7. In certlm.msc on the Connection Server, notice that it sets the vdm friendly name on the imported cert, but it doesn’t remove the vdm friendly name from the old cert. You’ll need to manually remove the vdm friendly name from the old cert.
    8. Then open services.msc and restart the VMware Horizon View Security Gateway Component.
    9. Repeat this process on the other Connection Servers.

Install Cert Manually

Alternatively, install a certificate without using Horizon Console:

  1. Run certlm.msc. Or run mmc, add the Certificates snap-in, and point it to Computer > Local Machine.
  2. Request a new certificate with a common name that matches the FQDN of the Connection Server or import a wildcard certificate.
  3. Note: the private key must be exportable. If using the Computer template, click Details, and then click Properties.
  4. On the Private Key tab, click Key options to expand it, and check the box next to Mark private key as exportable.
  5. In the list of certificates, look for the one that is self-signed. The Issuer will be the local computer name instead of a Certificate Authority. Right-click it, and click Properties.
  6. On the General tab, clear the Friendly name field, and click OK.
  7. Right-click your Certificate Authority-signed certificate, and try to export it.
  8. On the Export Private Key page, make sure Yes, export the private key is selectable. If the option to export the private key is grayed out, then this certificate will not work. Click Cancel.
  9. Right-click your Certificate Authority-signed certificate, and click Properties.
  10. On the General tab, in the Friendly name field, enter the text vdm, and click OK. Note: only one certificate can have vdm as the Friendly name.
  11. Then restart the VMware Horizon View Connection Server service. It will take several minutes before you can connect to Horizon Administrator Console.
  12. Horizon Console > Monitor > Dashboard > System Health > View > Components > Connection Servers should show the TLS Certificate as Valid.

Horizon Portal – Client Installation Link

If you point your browser to the Horizon Connection Server (without /admin in the path), the Install VMware Horizon Client link redirects to the Omnissa.com site for downloading of Horizon Clients. You can change it so that the Horizon Clients can be downloaded directly from the Horizon Connection Server.

  1. These instructions changed in Connection Server 2406.
  2. On the Horizon Connection Server, go to C:\Program Files\VMware\VMware View\Server\broker\webapps\portal.
  3. Create a new folder called downloads.
  4. Copy the downloaded Horizon Client 2406 for Windows to the new C:\Program Files\VMware\VMware View\Server\broker\webapps\portal\downloads folder.
  5. Run Notepad as administrator.
  6. Open the file C:\ProgramData\VMware\VDM\portal\portal-links-html-access.properties file with a text editor (as Administrator).
  7. Go back to the downloads folder and copy the Horizon Client filename.
  8. In Notepad, modify link.win32 and link.win64 by specifying the relative path to the Horizon Client executable under /downloads. There’s only one Horizon client for both 32-bit and 64-bit. The following example shows a link for the Horizon win64 client. 
    link.win64=/portal/downloads/VMware-Horizon-Client-2406-8.13.0-9986028157.exe
  9. Then Save the file.
  10. Restart the VMware Horizon View Web Component service or restart the entire Connection Server.
  11. It will take a few seconds for the ws_TomcatService process to start, so be patient. If you get a 503 error, then the service is not done starting.
  12. Now when you click the link to download the client, it will grab the file directly from the Horizon Connection Server.
  13. Repeat these steps on each Connection Server.

Portal Branding

Paolo Valsecchi at VMware Horizon 8: customize the login page details how to brand the Horizon portal page.

VMware vRealize Operations for Horizon 6.7.0

Last Modified: Nov 7, 2020 @ 6:34 am

💡 = Recently Updated

Change Log

Planning

vRealize Operations for Horizon is composed of several components:

  • vRealize Operations Manager appliance – this is the same vROps appliance deployed for monitoring of vSphere infrastructures, and hence it can monitor the vSphere clusters that are hosting the Horizon Agents.
  • Horizon Adapter for vRealize Operations – this is a .pak file installed on a vROps appliance. The Horizon Adapter receives data from one or more Broker Agents.
    • Broker Agent is installed on top of a Horizon Collection Server in each Horizon pod. The Broker Agent collects information from Horizon Connection Servers (e.g. events database), and feeds the data to the Horizon Adapter running on a vRealize Operations Manager appliance. The Broker Agent can also collect data from Unified Access Gateway, and App Volumes.
  • vROps Dashboards, Reports, and Alerts for Horizon – these display the information collected by the Horizon Adapter. Installation of the Horizon Adapter .pak file automatically imports the Dashboards, Reports, and Alerts.

The Horizon Adapter and Broker Agent should be the same version.

The vROps Horizon monitoring solution components have different versions:

vRealize Operations Manager 6.6 and newer has a new HTML5 user interface that looks quite different from vRealize Operations Manager 6.5 and older, thus necessitating a new post. See the post vRealize Operations for Horizon 6.4 for the older vROps user interface, and older Horizon Adapters.

vRealize Operations for Horizon comes with two licenses:

  • vRealize Operations Manager Enterprise license – enables vSphere monitoring for Horizon workloads. The license does not entitle vSphere monitoring of non-Horizon workloads.
  • vRealize Operations for Horizon Adapter license – enables the Horizon Adapter to collect data from the Horizon Broker Agent for a specific number of Horizon Agent machines. The Horizon 7 Enterprise License can also be used to license the Adapter.

Deploy New vROps Appliance

If you are upgrading an existing vROps appliance, skip ahead to the Patch/Upgrade Appliance section.

For new installations of vROps, download the following:

  1. See VMware’s Product Interoperability Matrix to determine which combinations of vROPs and Horizon Adapter are compatible with your version of Horizon. Also see the 6.7.1 Adapter Release Notes.
    • 6.7.1 Adapter supports VMware Horizon 7.7 or later
    • 6.7.1 Adapter requires vRealize Operations Manager 8.0 or later
    • 6.7.1 Adapter supports VMware App Volumes 2.14.8 to 2.18
    • 6.7.1 Adapter supports VMware Unified Access Gateway 3.6 and later
  2. If vRealize Operations Manager for Horizon 6.7.1, then download vRealize Operations Manager 8.0 from the vRealize Operations Manager for Horizon 6.7.0 download page.
