Navigation

This page details creation of session profiles and session policies for NetScaler Gateway 11.1 where ICA Only is checked.

Partly based on Citrix Knowledgebase Article CTX139963 – How to Configure NetScaler Gateway with StoreFront

Session Profiles/Policies CLI Commands

The CLI commands are shown below:

add vpn sessionAction "Receiver Self-Service" -transparentInterception OFF -defaultAuthorizationAction ALLOW -SSO ON -icaProxy ON -wihome "https://storefront.corp.com" -ntDomain Corp -clientlessVpnMode OFF -storefronturl "https://storefront.corp.com"

add vpn sessionAction "Receiver for Web" -transparentInterception OFF -defaultAuthorizationAction ALLOW -SSO ON -icaProxy ON -wihome "https://storefront.corp.com/Citrix/StoreWeb" -ntDomain Corp -clientlessVpnMode OFF

add vpn sessionPolicy "Receiver Self-Service" "REQ.HTTP.HEADER User-Agent CONTAINS CitrixReceiver" "Receiver Self-Service"

add vpn sessionPolicy "Receiver for Web" "REQ.HTTP.HEADER User-Agent NOTCONTAINS CitrixReceiver" "Receiver for Web"

Session Profiles

Or use the GUI to create the policies/profiles:

  1. On the left, expand NetScaler Gateway, expand Policies and click Session.
  2. On the right, switch to the Session Profiles tab, and click Add.
  3. Name the first one ReceiverSelfService or similar. This is for Receiver Self-Service (not in a web browser).
  4. Switch to the Client Experience tab.
  5. On the Client Experience tab, check the Override Global box next to Clientless Access and set it to Allow. Scroll down.
  6. Check the Override Global box next to Plug-in Type and set it to Java.
  7. Check the Override Global box next to Single Sign-on to Web Applications and enable it. Scroll up.
  8. If you need two-factor authentication, the session policy for Receiver Self-Service needs to be adjusted to indicate which authentication field contains the Active Directory password. On the Client Experience tab is Credential Index. This needs to be changed to SECONDARY. Leave the session policy for Web Browsers set to PRIMARY.
  9. On the Security tab, check the Override Global box next to Default Authorization Action and set it to Allow.
  10. On the Published Applications tab, check the Override Global box next to ICA Proxy and set it to ON.
  11. Check the Override Global box next to Web Interface Address and enter the load balanced URL to the StoreFront servers. You can use an IP address. Don’t add any path to the end of the URL.
  12. If you only have one domain, then check the Override Global box next to Single Sign-on Domain and enter the name of your Active Directory domain. StoreFront needs to accept this domain name (Configure Trusted Domains).
  13. If you have multiple domains, then leave Single Sign-on Domain field blank, and ensure the LDAP authentication servers have userPrincipalName in the SSO Name Attribute field.
  14. For Account Services Address, enter the Base URL for StoreFront. NetScaler needs to be able to resolve this DNS name.
  15. Click Create.
  16. Click the ellipsis next to the existing session profile and click Add. This copies the settings from the existing profile into the new one.
  17. Change the name of the second Session Profile to ReceiverForWeb or similar.
  18. On the Client Experience tab, Clientless Access should be set to Allow. Scroll down.
  19. Plug-in Type should still be set to Java.
  20. Single Sign-on to Web Applications should be enabled.
  21. If you need two-factor authentication, the session policy for Receiver for Web needs Credential Index set to PRIMARY. Only the Receiver Self-Service policy needs SECONDARY as detailed earlier.
  22. On the Security tab, the Default Authorization Action should still be Allow.
  23. On the Published Applications page, for the Web Interface Address field, add the path to your Receiver for Web site (e.g. /Citrix/StoreWeb).
  24. Everything else should be the same. If you only have one domain, then check the Override Global box next to Single Sign-on Domain and enter the name of your Active Directory domain. If you have multiple domains, then leave this field blank and ensure the LDAP authentication servers have userPrincipalName in the SSO Name Attribute field.
  25. Account Services Address is not needed in this profile but there’s no harm in leaving it.
  26. Click Create.

Session Policies

  1. On the right, switch to the Session Policies tab, and click Add.
  2. Name the Policy ReceiverSelfService or similar.
  3. Change the Request Profile to ReceiverSelfService.
  4. In the Expression box, either type in the following, or use the Expression Editor link to build the following expression: 
    REQ.HTTP.HEADER User-Agent CONTAINS CitrixReceiver

  5. Then click Create.
  6. Add another policy, and name it ReceiverForWeb or similar.
  7. Change the Action to ReceiverForWeb.
  8. In the Expression box, either type in the following, or use the Expression Editor. It’s the same as the previous expression, except it’s NOTCONTAINS instead of CONTAINS. 
    REQ.HTTP.HEADER User-Agent NOTCONTAINS CitrixReceiver
  9. Click Create.

VMware Horizon 7 – Cloud Pod Architecture

Last Modified: Oct 24, 2020 @ 6:29 am

This post applies to all VMware Horizon 7 versions including 7.13 (ESB) and 7.10.3 (ESB).

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 – View Administrator 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 Limits in Horizon 7.11 and newer:

  • 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

Cloud Pod Limits in Horizon 7.8 and newer:

  • Max users = 250,000
  • Max Pods = 50
  • Max Sessions per Pod = 10,000
  • Max Sites = 15
  • Max Connection Servers per Pod = 7
  • Max Horizon Connection Server Instances = 350

Cloud Pod Limits in Horizon 7.6:

  • Max users = 200,000
  • Max Pods = 25
  • Max Sessions per Pod = 10,000
  • Max Sites = 10
  • Max Connection Servers per Pod = 7
  • Max Horizon Connection Server Instances = 175

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.

For more information on multi-datacenter design for Horizon 7, see VMware Horizon 7 Enterprise Edition Multi-Site Reference Architecture, which is an 88-page document that includes the following:

  • Identity Manager
  • App Volumes
  • Horizon 7 Cloud Pod Architecture
  • User Environment Manager
  • SQL AlwaysOn Availability Groups
  • Nnetworking
  • Storage (e.g vSAN)
  • Active Directory
  • Distributed File System
  • Global Load Balancing

Initialize First Pod

As of Horizon 7.8, Cloud Pod can be configured in Horizon Console (https://myConnectionServer/newadmin).

  1. In Horizon Console, expand Settings and click Cloud Pod Architecture. Or in View Administrator, on the left, expand View Configuration, 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. If prompted, click OK to reload the client.

    • Then on the left, expand View Configuration, and click Cloud Pod Architecture.
  6. On the right, feel free to rename the federation by clicking the Edit button.

    1. Enter a new name.

  7. On the left, expand Settings (or View Configuration), and click Sites.

  8. 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.

    1. Enter a Site name.

  9. Click the Site to highlight it to reveal the Pods on the bottom half of the window.
  10. Highlight the pod and click Edit to make the name more descriptive.

    1. Enter a Pod name.

  11. See VMware 2080522 Restoring View Connection Server instances in a Cloud Pod Architecture pod federation.

Additional Pods – Join Federation

  1. Connect to View Administrator or Horizon Console in the second pod.
  2. On the left, expand Settings (or View Configuration), 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. If prompted, click OK to reload the client.
  8. On the left, expand Settings (or View Configuration, and click Sites.

  9. If this pod is in a different site, then in the top half of the window click Add to create a new site.

  10. Give the site a name, and click OK.

  11. Highlight the first site.
  12. On the bottom, highlight the new pod, and click Edit.

  13. Rename the pod and put it in the 2nd site. Click OK.

  14. In Horizon 7.7 and newer, the top of Horizon Administrator 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

Pools and Entitlements are two different things. You can create a pool without entitling anybody to the pool.

Local Entitlements and Global Entitlements are two different things. Global Entitlements are created separately, and then you assign pools from multiple pods to the Global Entitlement.

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. Instead, create a Global Entitlement and add the local pool to it.

  1. In Horizon Console (or View Administrator), on the left, expand Inventory (or Catalog), and click Global Entitlements.

  2. On the right, click Add.

  3. In the Type page, select Desktop Entitlement or Application Entitlement, and click Next.

  4. In the Name and Policies page, give the entitlement (icon) a name. For Application Entitlements, it’s one entitlement per application so include the application name.
  5. Horizon 7.2 and newer lets you configure tag restrictions (Connection Server restrictions) from this wizard.
  6. Horizon 7.3 and newer lets you select a Category Folder where the published icon will be placed on the client’s Start Menu. This feature requires Horizon Client 4.6 and newer.
  7. Horizon 7.5 and newer let you put the published icon on the endpoint’s desktop too. See Create Shortcuts for a Desktop Pool at VMware Docs.

    1. Configure Category Folder.

  8. Scroll down to the Policies section and configure the following:
    1. The Use home site checkbox tells the global entitlement to respect user home sites.
    2. Change the Default display protocol to VMware Blast.

    3. In newer versions of Horizon, you can allow users to reset/restart their machines.
    4. Check the box next to HTML Access.
    5. Horizon 7.2 adds 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.
    6. Horizon 7.3 adds 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:

      • Windows clients only. If the this feature is enabled, then all non-Windows clients are blocked.
      • Horizon Client 4.6 and newer. All other versions are blocked.
      • In Horizon 7.8 and newer, the Active Directory security group can contain client computers that belong to any AD Organizational Units (OUs) or default Computer container. For older versions of Horizon, the computers must be in the Computer container.
      • See Implementing Client Restrictions for Desktop and Application Pools at VMware Docs.
    7. Horizon 7.7 and newer have a selection for Multi-Session Mode. Pre-launch must be disabled to enable this setting.
    8. 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. Double-click the new global entitlement or click the link for the name of the Global Entitlement.

  13. Switch to the Local Pools tab.
  14. On the Local Pools tab, click Add.

  15. 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 Administrator or Horizon Console to the other pod and edit the Global Entitlement from there.

  16. Go to another pod and view the Global Entitlements.
  17. On the right, double-click the Global Entitlement or click the hyperlink for the name of the Global Entitlement.

  18. On the Local Pools tab, click Add to add pools from this pod.

  19. Horizon Console 7.11 and newer can configure backup global entitlements. 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 Backup Global Entitlement containing the backup pools. You don’t have to assign anybody to the Backup Global Entitlement.
    2. Edit the production Global Entitlement.
    3. Under Backup Global Entitlement, click Browse.
    4. Change the selection to Backup Global Entitlement, select the Backup Global Entitlement and click Submit.
  20. Horizon Console 7.11 and newer at Inventory > Desktops can show if a Local Pool is a member of a Global Entitlement.

Monitoring

  1. Once Global Entitlements are enabled, a new Search Sessions node is added, which allows you to search for sessions across federated pods. The Search Sessions node is available in Horizon Console 7.9.

  2. The Dashboard in Horizon Administrator shows the health of remote pods. The Dashboard has not yet been added to Horizon Console.

Home Sites

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

Horizon 7 lets you configure Home Sites for users from within Horizon Administrator. Horizon 7.8 lets you configure Home Sites for users from within Horizon Console.

  1. Configure your Cloud Pod Architecture with multiple Sites and at least one Pod per Site.
  2. In Horizon Console or Horizon Administrator, on the left, click Users and Groups.

  3. On the right, switch to the Home Site tab (or Home Site Assignment tab).
  4. Click Add.

  5. Find a user or group for this home site, and click Next.

  6. Select the site to assign the users to and click Finish.

  7. Home Sites can be assigned to both users and groups. User assignments override group assignments.

  8. Edit your Global Entitlement and ensure that Use Home Site is checked. You can optionally require that each user has a Home Site.
  9. 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.

    • In Horizon Administrator, double-click a Global Entitlement, switch to the Home Site Override tab, and click Add.
  10. 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.
    • In Horizon Administrator, on the Users and Groups page, on the Home Site tab, if you switch to the Resolution sub-tab, you can find a user name, click Look Up and see which Home Site is assigned to the user for each entitlement.

VMware Horizon 7 – RDS Farms/Pools

Last Modified: Nov 11, 2020 @ 1:18 pm

Navigation

This post applies to all VMware Horizon 7 versions including 7.13 (ESB) and 7.10.3 (ESB).

Change Log

Overview

This post details VMware Horizon configuration for Remote Desktop Session Host (RDS) Horizon Agents. Virtual Desktops are detailed at Master Virtual Desktop and Virtual Desktop Pools.

Before following this procedure, build a master RDS Session Host.

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.

Horizon 7.7 and newer support up to 200 RDS farms, and each farm with up to 500 RDS hosts.

  • Horizon 7.6 and older support up to 200 RDS farms, and each farm with up to 200 RDS hosts.

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.

VMware Tech Paper Best Practices For Published Applications And Desktops in VMware Horizon 7:

  • vSphere Best Practices – Hardware, Network Adapters, ESXi BIOS Settings, ESXi Power Management
  • Core Services Best Practices – Active Directory, DNS, DHCP, NTP, KMS, RDS Licensing
  • ESXi Host Sizing Best Practices
  • RDSH Configuration Best Practices – Optimization
  • Horizon 7 Best Practices – Instant Clones, Load Balancing
  • User Environment Management Best Practices – Horizon Smart Policies, Folder Redirection, User Profiles, Printers, Hardware Graphics Acceleration
  • App Volumes Best Practices – dedicated AppStacks
  • Antivirus Best Practices
  • Maintenance Operations Best Practices – scheduled reboots

RDS Farms – Instant Clones and Composer Linked Clones

Horizon 7.1 and newer offers two methods of creating RDS Farm linked clones:

  • Instant Clones
  • Composer Linked Clones

Instant Clones are the preferred method. Here is the process: 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.
  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.

The other RDS Linked Clone option is Horizon Composer. Here are some notes:

  • When Composer creates Linked Clones, Composer uses SysPrep with Customization Specifications. SysPrep is slow.
  • SysPrep is also used whenever the RDS farm is updated with a new master image snapshot.
  • No View Storage Accelerator.
  • No Rebalance.
  • No Refresh. The machines are persistent until you Recompose the farm.
    • The delta disks continue to grow until you Recompose the farm.
    • You can enable Space Reclamation to shrink the delta disks as files are deleted.

Customization Specification – Composer Linked Clones only

If you are using Instant Clones (7.1 and newer), then skip to creating the RDS farm. Customization Specifications are only needed for Composer Linked Clones.

  1. In vCenter, from the Home page, click Customization Specification Manager.
  2. Click the icon to create a new Customization Specification.
  3. In the Specify Properties page, give the spec a name and click Next.
  4. In the Set Registration Information page, enter your normal settings and click Next.
  5. In the Set Computer Name page, select Use the virtual machine name and click Next.
  6. In the Enter Windows License page, select Per seat and click Next.
  7. In the Set Administrator Password page, enter the local administrator password and click Next.
  8. In the Time Zone page, select the time zone and click Next.
  9. In the Run Once page, click Next.
  10. In the Configure Network page, leave it set to Use standard network settings. Horizon requires the VMs to be configured for DHCP. Click Next.
  11. In the Set Workgroup or Domain page, enter credentials that can join the machines to the domain, and click Next.
  12. In the Set Operating System Options page, leave the box checked, and click Next.
  13. In the Ready to complete page, click Finish.

Create an Automatic RDS Farm

If you upgrade vCenter to 6.7, then you must upgrade your ESXi hosts to 6.7 at the same time. Afterwards, take a new snapshot of the master image and perform a push operation. See Upgrade Instant-Clone Desktop Pools at VMware Docs.

Master Image Preparation

  1. Make sure your RDS master Agent has the VMware Horizon Instant Clone Agent feature, or the VMware Horizon View Composer Agent feature installed. You can install one or the other, but not both. Instant Clone Agent is the preferred option.
  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 Linked 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 VMware 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.

Horizon Console

This section uses Horizon Console (https://<View_Connection_Server>/newadmin) to create a new RDS Farm. If you prefer Horizon Administrator, or if your Horizon isn’t 7.5 or newer, then skip to the next section.

  1. In Horizon Console, on the left, expand Inventory, and click Farms.
  2. On the right, click Add.
  3. In the Type page, select Automated Farm, and click Next.
  4. In the vCenter Server page, select Instant Clone, select the vCenter Server, and then click Next.
  5. In the Storage Optimization page, click Next.
  6. 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. In the Identification and Settings page, in Horizon 7.3.1 and newer, if you set the Default display protocol to PCoIP, then HTML5 Blast won’t work unless Allow users to choose protocol is set to Yes. See VMware Communities Upgraded from 7.0.1 to 7.3.1, getting “You cannot access your applications or desktops”… error.
    5. Horizon 7.2 and newer support 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.
    6. 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.
    7. For Log off disconnected sessions, specify a disconnect timer. This is in addition to the idle timer configured in Global Settings.
    8. To access the Pools/Farm from a web browser using HTML Blast, check the Enabled box next to Allow HTML Access.
    9. 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.
    10. Max sessions per RDS Host will block connections if this number is exceeded.
  7. Click Next.
  8. In the Provisioning Settings page:
    1. Enter a Naming Pattern. Make sure the name includes {n:fixed=3} or something like that.
    2. In Farm Sizing, enter the number of machines to create.
  9. Click Next.
  10. In the vCenter Settings page, click Browse next to each option and make a selection. These are self-explanatory. Then click Next.
  11. Horizon Administrator 7.8 and newer let you configure Load Balancing Settings for the RDS Farm. You cannot yet configure these settings in Horizon Console. After the RDS Farm is created, you can use Horizon Administrator to edit these settings.
  12. 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.
  13. Click Next.
  14. 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.

Horizon Administrator

  1. In Horizon Administrator, on the left, expand Resources, and click Farms.
  2. On the right, click Add.
  3. In the Type page, select Automated Farm, and click Next.
  4. In the vCenter Server page, select Instant clones or View Composer linked clones depending on which agent you have installed on your RDS master Agent machine.
  5. Select the vCenter Server, and click Next.
  6. In the Identification and Settings page, enter a name for the Farm. A VM folder with the same name will be created in vCenter.
  7. In the Farm Settings section, set Default Display protocol to VMware Blast.
  8. In Horizon 7.3.1 and newer, if you set the Default display protocol to PCoIP, then HTML5 Blast won’t work unless Allow users to choose protocol is set to Yes. See VMware Communities Upgraded from 7.0.1 to 7.3.1, getting “You cannot access your applications or desktops”… error.
  9. Horizon 7.2 and newer support 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.
  10. 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.
  11. For Log off disconnected sessions, specify a disconnect timer. This is in addition to the idle timer configured in View Configuration > Global Settings.
  12. To access the Pools/Farm from a web browser using HTML Blast, check the Enabled box next to Allow HTML Access.
  13. Horizon 7.4 adds a new 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.
  14. Click Next.
  15. Horizon 7.8 and later have a Load Balancing Settings page that lets you configure the load evaluator rules without having to modify any script. In general, use stable, non-fluctuating rules like session count and Memory usage. Note that CPU usage tends to wildly fluctuate and can prematurely disable connections to an RDS Host. Click Next when done configuring rules.
  16. In the Provisioning Settings page, enter a naming pattern. Make sure the name includes {n:fixed=3} or something like that.
  17. Enter the number of machines to create, and click Next.
  18. In the Storage Optimization page, click Next.
  19. In the vCenter Settings page, click Browse next to each option, and make a selection.
  20. When selecting a datastore, Instant Clones sets the Storage Overcommit to Unbounded automatically. For Composer Linked Clones, set it to Unbounded. Click OK, and then click Next.

  21. If Composer, in the Advanced Storage Options page, decide if you want space reclamation or not. Space reclamation does reduce disk space but increases IOPS while the operation is occurring. If space reclamation is enabled, also configure a Blackout window so the increased IOPS does not affect production usage. Scroll down.
  22. If you scroll down, you’ll see an option for Transparent Page Sharing. By default it is disabled. You can enable it by setting it to Global. This should reduce some memory consumption. Click Next.
  23. For both Instant Clones and Composer, in the Guest Customization page, select an OU.
  24. Consider the Allow reuse of pre-existing computer accounts check box.
  25. For Composer Linked Clones, select a customization specification, and click Next.
  26. In the Ready to Complete page, click Finish.
  27. If you double-click the farm, on the RDS Hosts tab, you can see the progress of the farm creation operation.
  28. Horizon 7.7 and newer show you the status of RDS Drain Mode, which can be enabled on the RDS Host by running change logon /drain.
  29. If Composer, since RDS Farms use SysPrep, it will take some time before they become available.
  30. Once the RDS Hosts are created, you publish resources from them by either creating a Desktop Pool, or an Application Pool, or both.

  • Windows Server 2019 is supported for Horizon Agents 7.7 and newer.
  • Windows Server 2016 is supported for Horizon View Agents 7.0.3 and newer.
  • For 2012 R2 or newer, set the vCPUs to 8. For 2008 R2, set the vCPUs to 4. Two is the minimum. See VMware whitepaper for more information.
  • 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 Controller. Obviously this is bad.

Install/Upgrade Dynamic Environment Manager (DEM) Agent

Dynamic Environment Manager (DEM) is the new name for User Environment Manager (UEM).

If you are licensed for Dynamic Environment Manager (Horizon Enterprise Edition), install the Dynamic Environment Manager (DEM) Enterprise Agent.

  • DEM Enterprise has the same or more features that has always been included in Horizon Enterprise. DEM Standard is a reduced-feature version for Horizon 8 Standard Edition.
  • Note: UEM 9.1 and newer can also work without Active Directory (Group Policy); see VMware 2148324 Configuring advanced UEM settings in NoAD mode for details.

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 VMware 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 VMware Docs. For the list of additional registry values, see FlexEngine Configuration for Computer Environment Settings at VMware 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-2212-10.8-GA\VMware Dynamic Environment Manager Enterprise 2106 10.3 x64.msi" /qn COMPENVCONFIGFILEPATH=\\fs01\DEMConfig\general

UEM 9.6 and newer are supported on Windows Server 2019.

To install the DEM Enterprise Agent:

  1. Make sure Prevent access to registry editing tools is not enabled in any GPO. This setting prevents the FlexEngine from operating properly.
  2. Based on your entitlement, download either DEM 2212 (10.8) Enterprise Edition, or DEM 2212 (10.8) Standard Edition.

  3. Run the extracted VMware Dynamic Environment Manager Enterprise 2212 10.8 x64.msi.
  4. In the Welcome to the VMware Dynamic Environment Manager Enterprise Setup Wizard page, click Next.
  5. In the End-User License Agreement page, check the box next to I accept the terms, and click Next.
  6. In the Destination Folder page, click Next.
  7. The Choose Setup Type page appears. By default, the installer only installs the engine. You can click Custom or Complete to also install the Management Console. The Management Console is typically installed on an administrator workstation, not on a master image.

  8. In the Choose License File page, if installing on a Horizon Agent, then no license file is needed. Click Next.
  9. In the Ready to install VMware Dynamic Environment Manager Enterprise page, click Install.
  10. In the Completed the VMware Dynamic Environment Manager Enterprise Setup Wizard page, click Finish.
  11. If you have PCoIP Zero Clients that map USB devices (e.g. USB drives), then you might have to set the following registry value: (Source = VMware 2151440 Smart card SSO fails when you use User Environment Manager with a zero client)
    • HKLM\Software\VMware, Inc.\VMware VDM\Agent\USB
      • UemFlags (DWORD) = 1

Horizon Agent Load Balancing Script

If you have multiple identical Remote Desktop Services Hosts in a single RDS Farm, by default, VMware Horizon uses a least connections Load Balancing algorithm.

In Horizon 7.8 and newer, you can edit Load Balancing rules directly in Horizon Administrator. You cannot yet configure these settings in Horizon Console. For existing RDS Farms, edit the RDS Farm to see the new settings. Or when creating a new RDS Farm a new page asks you for these settings.

In Horizon 7.7 and older, you can change the load balancing algorithm to be performance-based by configuring scripts on each RDS Host. See Configuring Load Balancing for RDS Hosts at VMware Docs.

There are only three levels of load: HIGH, MED, and LOW. Within a load level, Horizon selects an RDS server at random.

Do the following to configure the Load Balancing script:

  1. The script must be placed at C:\Program Files\VMware\VMware View\Agent\scripts on every RDS Host. VMware provided a couple sample scripts that you can use. One script only looks at CPU and the other script only looks at Memory. If you write your own script, make sure it exists in this folder on every RDS Host in the RDS Farm.
  2. Open Services, and configure the VMware Horizon View Script Host service to run automatically.

  3. Then start the service.
  4. In regedit, go to HKLM\Software\VMware, Inc.\VMware VDM\ScriptEvents\RdshLoad.
  5. Create a new String Value. It doesn’t matter what you name it but the script name is recommended.
  6. Modify the String Value and enter cscript.exe “PathToScript”. For example: cscript.exe "C:\Program Files\VMware\VMware View\Agent\scripts\cpuutilisation.vbs"
  7. After setting the registry value, restart the VMware Horizon View Agent service.
  8. After you later add this RDS Host to a RDS Farm in Horizon Administrator, click the Dashboard view.
  9. Expand RDS Farms, expand the farm, and click the RDS Host.
  10. Make sure the Server load is reported.

Microsoft FSLogix

Why FSLogix?

Microsoft FSLogix has two major features:

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

VMware 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 Licensing 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.

VMware OS Optimization Tool

  1. See VMware Windows Operating System Optimization Tool Guide for details on this tool.
  2. Download the VMware OS Optimization Tool VMware fling.
  3. Run the extracted VMwareOSOptimizationTool.exe.
  4. On the Optimize tab, choose a template.
  5. Then click Analyze on the bottom of the window.
  6. On the Optimize tab, review the optimizations, and make changes as desired. Then on the bottom left, click Optimize.
  7. The History tab lets you rollback the optimizations.

Seal and Snapshot

  1. Go to the properties of the C: drive, and run Disk Cleanup.
  2. On the Tools tab, click Optimize to defrag the drive.
  3. Run slmgr.vbs /dlv and make sure it is licensed with KMS and has at least one rearm remaining.
  4. Run Delprof2 to clean up local profiles. Get it from http://helgeklein.com/download/.
  5. Make sure the master session host is configured for DHCP.
  6. Session hosts commonly have DHCP reservations.

  7. Run antivirus sealing tasks:
    1. Symantec: Run a full scan and then run the Virtual Image Exception tool – http://www.symantec.com/business/support/index?page=content&id=TECH173650
    2. Symantec: run the ClientSideClonePrepTool –http://www.symantec.com/business/support/index?page=content&id=HOWTO54706
  8. Base Image Script Framework (BIS-F) automates many image sealing tasks. The script is configurable using Group Policy.
  9. Shutdown the master session host.
  10. Edit the Settings of the master virtual machine, and disconnect the CD-ROM. Make sure no ISO is configured in the virtual machine.
  11. Take a snapshot of the master session host. View Composer and Instant Clone require a snapshot.

  12. Use can now use Horizon View Administrator to create RDS Farms.

Full Clone Post-Cloning Tasks

If you used vCenter to clone the machine instead of using Horizon Composer, 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 always 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 – 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. View Administrator – In View Administrator, add the new machine to a Remote Desktop Services farm.

VMware Horizon 7 – Virtual Desktop Pools

Last Modified: Mar 8, 2022 @ 8:04 am

56 Comments

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-7-rds-farmspools/.

Navigation

This post applies to all VMware Horizon 7 versions including 7.13 (ESB) and 7.10.3 (ESB).

Change Log

Non-Persistent – Instant Clone vs Composer

In general, use Instant Clone, if possible. Here are some advantages of Instant Clone over Composer:

  • No Composer server needed.
  • Faster provisioning and recompose, and lower IOPS during these operations.
  • If multiple datastores, rebalance is automatic.
    • With Composer, rebalance is a manual operation.
  • Composer features like Disposable Disks and disk space reclamation are not needed with Instant Clones.

Requirements for Instant Clones:

  • Horizon Enterprise licenses
    • All editions of Horizon 7.13 includes Instant Clone licensing. Since Composer was removed from Horizon 8, start migrating to Instant Clones.
  • ESXi 6 Update 1 or newer
  • Virtual Machine hardware version 11 or newer
  • View Storage Accelerator must be enabled

Notes on Instant Clones:

  • Horizon 7.9 and newer support delaying desktop refresh (not recommended), just like you can with Composer.
  • Horizon 7.3 and newer support dedicated desktop pools.
  • Horizon 7.1 and newer support Linked Clones for RDS Pools.
  • The master VM snapshot is copied to every LUN containing instant clones. Composer does the same.
  • Instant Clone pools create “Parent” machines 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.
    • For lower density pools, Horizon 7.13 supports Smart Provisioning, which eliminates the need for “Parent” machines when there are less than 12 single-pool VMs per host. See the Smart Provisioning YouTube video for an overview.
    • Prior to Horizon 7.13, Instant Clone pools always create Parent machines no matter the size of the Instant Clone pool.
    • Composer does not need parent virtual machines.
  • Persistent disks are not supported with Instant Clones
    • An alternative is VMware App Volumes Writable Volumes
  • Persona is not supported with Instant Clones.
  • See Instant-Clone Desktop Pools at VMware Docs.
  • Also see VMware Technical White Paper VMware Horizon 7 Instant-Clone Desktops and RDSH Servers

Infrastructure Prep

  • Each desktop pool points to one vSphere cluster.
  • Ensure vSwitch has sufficient ports for the new virtual desktops.
    • Instant clones require static port binding with the elastic port allocation. Do not change the port binding to ephemeral.
  • Ensure the VLAN has enough DHCP addresses for the desktop pool.
  • KMS Licensing is required – MAK licensing is not supported
  • 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 linked clone virtual desktops will be created.
  • If Instant Clone:
    • ESXi must be version 6 update 1 or newer
    • Master VM must be version hardware version 11 or newer
    • In Horizon Administrator, add Instant Clone Domain Accounts
    • In Horizon Administrator, enable View Storage Accelerator on your vCenter connection.
    • If you upgrade vCenter to 6.7, then you must upgrade your ESXi hosts to 6.7 at the same time. Afterwards, take a new snapshot of the master image and perform a push operation. See Upgrade Instant-Clone Desktop Pools at VMware Docs.

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 linked 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.
  • Linked clone Delta disks – Delta disks start small whenever the virtual desktop boots and grow until the virtual desktop is refreshed. To keep delta disks small, refresh the virtual desktops immediately after the user logs off. Otherwise, the delta disk could potentially grow to the same size as the C: drive.
  • If Composer:
    • Persistent disks can be used to store the user’s profile (but not user-installed applications). To enable Persistent disks, the pool must be Dedicated Assignment. You can place the persistent disks on a LUN that is separate from the linked clones LUN. How do you back up the persistent disks? A better option is to use VMware User Environment Manager instead of Persistent disks.
    • Disposable disks. In Dedicated Assignment pools, you have the option of creating Disposable Disks. These disks are always stored with the virtual desktop (you can’t choose a dedicated disposable disk LUN). If you’re planning to frequently refresh the desktops, there’s no point in using Disposable disks.

Floating (Non-Persistent) Automatic Linked Clone Desktop Pool

Master Image Preparation

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

  1. Video Memory – if Instant Clones, 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 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. For example, Horizon 7.9 supports six monitors in Windows 10 version 1803 and later.
  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 Linked 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 VMware 2150495 Computer-based Global Policy Objects (GPOs) that require a reboot to take effect are not applied on instant clones.
  5. KMS Licensing is required.
  6. Provisioning Agent – When installing Horizon Agent, select the imaging component you intend to use. You can install Instant Clone, or Composer, but not both.
    • All editions of Horizon 7.13 includes Instant Clone licensing. Since Composer was removed from Horizon 8, start migrating to Instant Clones.
  7. If Instant Clone, Persona must be disabled.
  8. Snapshot – Shut down the master image and take a new snapshot.

Floating Pool – Horizon Console

In Horizon 7.5 and newer, you can use the new Horizon Console (https://ConnectionServerFQDN/newadmin) to create an Instant Clone pool.

In Horizon 7.8 and newer, you can use the new Horizon Console (https://ConnectionServerFQDN/newadmin) to create a Composer pool, including Persistent Disks.

If prefer to use Horizon Administrator, then skip ahead to Floating Pool – Horizon Administrator.

  1. Login to Horizon Console (https://ConnectionServerFQDN/newadmin)
  2. On the left, under Inventory, click Desktops.
  3. In Horizon Console 7.10 and newer, 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.
  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 Identity Manager, 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:
    1. 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.
    2. 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.
    3. Select Provision all machines up-front to create all of the machines now.
    4. Or select Provision machines on demand, which tells Horizon to create the machines (up to the maximum) as users connect.
    5. 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. Click Next.
  13. In the vCenter Settings page, most of these are self-explanatory. Click Browse next to each option, and make your selection.
  14. If the Parent VM (aka 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.
  15. Instant Clones monitors/resolution – If Instant Clones, 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.
  16. Scroll down for more settings.
  17. 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.
  18. When selecting Networks, you can use the Network from the parent image, or uncheck the box and select a different network.
  19. Click Next when done.
  20. 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. This applies to Horizon Client 4.6 and newer. See Create Shortcuts for a Desktop Pool at VMware Docs.

      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. Newer versions of Horizon have an option to put the icon on desktop or Start Menu.
      4. Then click Submit.
    2. In the Desktop Pool Settings page, Horizon 7.9 and newer let you select a Session Type, which means you can optionally publish applications from virtual desktops.
    3. Change the selection for Automatically logoff after disconnect to After, and specify a disconnect timer.

      • Note: In Horizon 7.10 or newer, you can also use Group Policy to configure this. The GPO overrides the pool setting. Install the Horizon 7.10 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 7.10 also has an Idle Time Until Disconnect (VDI) for virtual desktops. 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.
  21. Click Next.
  22. In the Remote Display Settings page:
    1. In 3D Renderer, there’s an option for NVIDIA GRID VGPU if you have GPUs installed.
    2. Check the box next to HTML Access.
    3. 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.
  23. Click Next.
  24. 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.
  25. Click Next.
  26. In the Ready to Complete page, you may entitle users now, or leave it unchecked and to 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 7.11 and newer 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.


  7. Eventually the pool’s tabs named Machines and Machines (InstantClone Details) will show the new machines.

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.

Floating Pool – Horizon Administrator

  1. In View Administrator, on the left, expand Catalog, and click Desktop Pools.
  2. On the right, you can clone an existing pool. This action copies many of the settings from the existing pool into the new pool.
  3. Or just click Add.
  4. In the Type page, select Automated Desktop Pool, and click Next.
  5. In the User Assignment page, select Floating, and click Next.
  6. In the vCenter Server page, select either Instant clones, or View Composer linked clones.
    • All editions of Horizon 7.13 includes Instant Clone licensing. Since Composer was removed from Horizon 8, start migrating to Instant Clones.
  7. Select the vCenter server, and click Next.

  8. Pool name – In the Desktop Pool Identification page, enter a name for the pool. Horizon creates a vCenter VM folder with the same name as the Pool ID.
  9. Display name is the name of the icon displayed in Horizon Client.
  10. Access Group – Assign the pool to an Access group to restrict delegated administration. Note: If you intend to integrate with VMware Identity Manager (aka Workspace ONE), then make sure you select the root (/) Access group. Other Access Groups won’t work. Click Next.
  11. In the Pool Settings page, do the following:
    1. Horizon 7.3 lets you select a Category Folder where the published icon will be placed on the client’s Start Menu. This applies to Horizon Client 4.6 and newer. See Create Shortcuts for a Desktop Pool at VMware Docs.
    2. Horizon 7.5 adds an option to put the shortcut on the endpoint’s Desktop.
    3. Change the selection for Automatically logoff after disconnect to After, and specify a disconnect timer.
    4. If View Composer, change the selection for Delete or refresh desktop on logoff to Refresh Immediately. Instant Clones always refresh after logoff.
    5. Horizon 7.1 and newer allows users to restart machines gracefully, instead of a reset.
    6. Scroll down.
    7. In the Remote Display Protocol section, select a Default display protocol. New in Horizon 7 is VMware Blast.
    8. In Horizon 7.3.1 and newer, if you set the Default display protocol to PCoIP, then HTML5 Blast won’t work unless Allow users to choose protocol is set to Yes. See VMware Communities Upgraded from 7.0.1 to 7.3.1, getting “You cannot access your applications or desktops”… error.
    9. Composer and Instant Clone have different options for 3D Renderer. Horizon 7.1 adds an option for NVIDIA GRID VGPU when creating Instant Clones.

      • Monitors/Resolution – If Composer, increase the number of monitors and resolution. This causes more video memory to be allocated to the VMs. If Instant Clone, these settings are configured on the Master VM’s settings in vSphere Client.
    10. Check the box next to HTML Access.
    11. Horizon 7.4 adds the 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.
    12. Click Next.
  12. In the Provisioning Settings page, enter a naming pattern. You can use {n:fixed=3} to specify the location for the incremented numerals. Make sure the naming pattern does not conflict with any existing machines. Note: Instant Clones does not support manual machine names.
  13. Enter the maximum number of desktops to create. You can create all of them now or wait to create them as users connect. When a user connects to one of these desktops, Horizon immediately creates another desktop (up to the maximum) and powers it on.
    1. In Horizon 6.2 and newer, the maximum number of desktops per pool is 2,000. Ensure that the DHCP scope has enough addresses for the Max number of desktops specified here.
  14. Enter the number of spare (idle, unassigned, unused) desktops you want powered on. Horizon maintains this number up to the maximum number of desktops.
  15. Click Next.

  16. If Horizon Composer, in the Disposable File Redirection page, select Do not redirect disposable files, and click Next. Since we’re refreshing the desktops on logoff, there’s no need for a separate disposable disk.
  17. 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.
  18. In the vCenter Settings page, most of these are self-explanatory. Click Browse next to each option, and make your selection.
  19. Horizon 7.1 adds the ability to select multiple Networks for the Instant Clones.
  20. If the Parent 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.
  21. Instant Clones monitors/resolution – If Instant Clones, 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.
  22. Datastores – select one or more datastores on which the virtual desktops will be placed.
  23. If Composer – select your Storage Overcommit preference. Since you are refreshing desktops on every logoff, they should stay small, so Unbounded is probably acceptable. VMware recommends no more than 140 virtual desktops per VAAI-enabled LUN. If the LUN is not VAAI enabled, 64 is the maximum. If Instant Clone, Unbounded is the only option. Click OK when done.

  24. For Select Replica Disk Datastores, select one datastore for the replica, and then click OK.
  25. Then click Next.
  26. If Instant Clone, View Storage Accelerator and Transparent Page Sharing are enabled by default and can’t be disabled. Storage reclamation doesn’t make sense for Instant Clone.
  27. If Composer, in the Advanced Storage Options page, be aware of the following:
    • View Storage Accelerator creates digest files, which consumes disk space. Creation of the digest files requires IOPS. Make sure to set the blackout times so that this digest creation does not happen during peak hours.
    • Reclaim VM disk space is not useful for non-persistent desktops.
  28. If you scroll down, there’s a new Transparent Page Sharing Scope. The default is no sharing. Use one of the other options to enable sharing. Click Next.
  29. In the Guest Customization page, next to AD container, click Browse, and select the OU where virtual desktop computer objects will be placed. Horizon 7.3 lets you type (paste) into the AD container field.
  30. Consider checking the box next to Allow reuse of pre-existing computer accounts. Click Next.

  31. In the Ready to Complete page, you may entitle users now or later. Click Finish.
  32. To check the status of the virtual desktops, go to Catalog > Desktop Pools.
  33. Double-click the pool name.
  34. If you scroll down, the vCenter Server section has a State field.
  35. vSphere Client shows recent tasks.
  36. On the Inventory tab, click Machines (View Composer or InstantClone Details). There’s a refresh button.
  37. You can also view the status of the desktops by looking at the Dashboard.
  38. Your VMs should eventually have a status of Available.
  39. If you encounter issues with View Composer, see VMware 2087379 VMware Horizon View Composer help center
  40. If Instant Clone, the Master VM and the snapshot used by the Instant Clones must not be deleted.

  5. With Composer, it might take a few minutes for the machine to boot a couple times while running QuickPrep.
  6. The pool now has 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.

Horizon Console

This section uses Horizon Console. If you prefer Horizon Administrator, then skip to the next section.

  1. In Horizon Console, go to Inventory > Desktops.
  2. Click the link for a pool name.
  3. For Instant Clones, on the Summary tab, click Maintain, and then click Schedule.
  4. In the Image page, select the new snapshot. Notice the snapshot’s monitor/resolution settings. Click Next.
  5. 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.
  6. In the Ready to Complete page, click Finish.
  7. The pool’s Summary tab, near the bottom, indicates that the image is being pushed.

  8. You can click the tab named Machines (InstantClone Details) to check on the status of the push task. Notice the Pending Image.
  9. The snapshot is copied to each datastore.
  10. The snapshot is attached to a Replica, powered on, then powered off. Digest is then computed.
  11. 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.
  12. Once Replicas are prepared, each machine is rebooted once.
  13. Eventually the Pending Image field will be cleared and the desktops are available again.

Horizon Administrator

  1. In View Administrator, go to Inventory > Pools.
  2. Double-click a pool name.
  3. For Instant Clones, on the Summary tab, click Push Image, and then click Schedule.
  4. Or if Composer, click View Composer, and then click Recompose.
  5. In the Image page, select the new snapshot. Notice the snapshot’s monitor/resolution settings. Click Next.
  6. In the Scheduling page, decide when to apply this new image, and then click Next.
  7. In the Ready to Complete page, click Finish.
  8. On the Inventory tab, you can click Machines (InstantClone Details) or Desktops (View Composer Details) to check on the status of the push/recompose task. Notice the Pending Image.
  9. For both provisioning methods, the snapshot is copied to each datastore.
  10. For Instant Clone, the snapshot is attached to a Replica, powered on, then powered off. Digest is then computed. Then the Replica is attached to a parent, and the parent is powered on. This takes a bit of time. But the Instant Clones remain accessible until the Replica preparation is complete.
  11. Once Replicas are prepared, for Instant Clones, each machine is rebooted once. While with Composer, each virtual machine is rebooted three times, which can be painful. Composer consumes considerable IOPS and time during Recompose operation. To speed up Recompose, switch to Instant Clones.
  12. Eventually the Pending Image field will be cleared and the desktops are available again.

Host Maintenance – Instant Clones

In Horizon 7.1 and newer, ESXi hosts running Instant Clones can be placed into maintenance mode without any special instructions.

Instant-Clone Maintenance Utilities at VMware Docs:

  • 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. In Horizon 7.0.3, this utility is the only method to prepare a Instant Clone ESXi host for maintenance mode. Also see VMware 2144808 Entering and exiting maintenance mode for an ESXi host that has Horizon instant clones.
  • IcCleanup.cmd – use this utility to unprotect and delete some or all of the internal VMs created by instant clones. This command is available in Horizon 7.10 and newer.

Virtual Hardware

Lieven D’hoore has a desktop VM build checklist at VMware Horizon View – Windows 10 Golden Image Creation

  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 View Administrator to create a pool, 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.
  7. There’s no need for the Floppy drive so remove it.
  8. If you have any Serial ports, remove them.
  9. In Device Manager, after installing VMware Tools, make sure the video driver is VMware SVGA 3D.
  10. If not, you can use the driver at C:\Program Files\Common Files\VMware\Drivers\video_wddm.

Roaming user profiles are tied to the operating system version so profiles on Windows 8.1-based, Windows 10-based, or Windows Server 2012 R2-based computers are incompatible with roaming user profiles in earlier versions of Windows.

Profiles are compatible only between the following client and server operating system pairs:

  • v6 = Windows 10 1607 and newer, Windows Server 2016, Windows Server 2019
  • v5 = Windows 10 1511 and older
  • v4 = Windows 8.1 and Windows Server 2012 R2
  • v3 = Windows 8 and Windows Server 2012
  • v2 = Windows 7 and Windows Server 2008 R2

If Windows 8, install hotfix http://support.microsoft.com/kb/2887239.

If Windows 8.1, ensure update rollup 2887595 is installed. http://support.microsoft.com/kb/2890783

After you apply this update, you must create a registry key before you restart the computer.

  1. Run regedit.
  2. Locate and then tap or click the following registry subkey:
    HKEY_LOCAL_MACHINE\System\CurrentControlset\Services\ProfSvc\Parameters
  3. On the Edit menu, point to New, and then tap or click DWORD Value.
  4. Type UseProfilePathExtensionVersion.
  5. Press and hold or right-click UseProfilePathExtensionVersion, and then tap or click Modify.
  6. In the Value data box, type 1, and then tap or click OK.
  7. Exit Registry Editor.

After you configure the UseProfilePathExtensionVersion registry entry, you have to restart the computer. Then, Windows 8.1 creates a user profile and appends the suffix “.v4” to the profile folder name to differentiate it from version 2 of the profile in Windows 7 and version 3 of the profile in Windows 8. Then, Windows 8.1-based computers that have update rollup 2887595 installed and the UseProfilePathExtensionVersion registry entry configured use version 4 of the profile.

Windows 8 creates a new copy of the user profile and appends the suffix “.v3” in the profile folder name to differentiate it from the original version 2 profile for Windows 7. After that, Windows 8-based computers that have this hotfix installed and the UseProfilePathExtensionVersion registry entry configured use the version 3 profile for users.

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. VMware App Volumes, Unidesk) or App Streaming (e.g. ThinApp, Microsoft App-V).

Trend Micro Slow login on Citrix environment after installing OfficeScan (OSCE): The following registries can be used to troubleshoot the issue. These registries will allow a delay on the startup procedure of OSCE until the system has launched successfully. This avoids deadlock situations during login.

Citrix CTX136680 – Slow Server Performance After Trend Micro Installation. Citrix session hosts experience slow response and performance more noticeable while users try to log in to the servers. At some point the performance of the servers is affected, resulting in issues with users logging on and requiring the server to be restarted. This issue is more noticeable on mid to large session host infrastructures.

Trend Micro has provided a registry fix for this type of issue. Create the following registry on all the affected servers. Add new DWORD Value as:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TmFilterParameters] “DisableCtProcCheck”=dword:00000001

Install/Upgrade Dynamic Environment Manager (DEM) Agent

Dynamic Environment Manager (DEM) is the new name for User Environment Manager (UEM).

If you are licensed for Dynamic Environment Manager (Horizon Enterprise Edition), install the Dynamic Environment Manager (DEM) Enterprise Agent.

  • DEM Enterprise has the same or more features that has always been included in Horizon Enterprise. DEM Standard is a reduced-feature version for Horizon 8 Standard Edition.
  • Note: UEM 9.1 and newer can also work without Active Directory (Group Policy); see VMware 2148324 Configuring advanced UEM settings in NoAD mode for details.

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 VMware 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 VMware Docs. For the list of additional registry values, see FlexEngine Configuration for Computer Environment Settings at VMware 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-2212-10.8-GA\VMware Dynamic Environment Manager Enterprise 2106 10.3 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. Based on your entitlement, download either DEM 2212 (10.8) Enterprise Edition, or DEM 2212 (10.8) 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 2212 10.8 x64.msi.
  5. In the Welcome to the VMware Dynamic Environment Manager Enterprise Setup Wizard page, click Next.
  6. In the End-User License Agreement page, check the box next to I accept the terms, and click Next.
  7. In the Destination Folder page, click Next.
  8. The Choose Setup Type page appears. By default, the installer only installs the engine. You can click Custom or Complete to also install the Management Console. The Management Console is typically installed on an administrator workstation, not on a master image.

  9. In the Choose License File page, if installing on a Horizon Agent, then no license file is needed. 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. If you have PCoIP Zero Clients that map USB devices (e.g. USB drives), then you might have to set the following registry value. (Source = VMware 2151440 Smart card SSO fails when you use User Environment Manager with a zero client)
    • HKLM\Software\VMware, Inc.\VMware VDM\Agent\USB
      • UemFlags (DWORD) = 1

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 VMware Docs.

Composer – Rearm

By default, when View Composer creates linked clones and runs QuikPrep, one of the tasks 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 VMware Blog Post VMware Horizon View Secret Weapon. The article describes configuring VMware Horizon View Script Host service to run a script to change PCoIP configuration based on the Connection Server that the user connected through. Full script is included in the article.

Microsoft FSLogix

Why FSLogix?

Microsoft FSLogix has two major features:

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

VMware 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 Licensing 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.

VMware OS Optimization Tool

  1. See VMware Windows Operating System Optimization Tool Guide for details on this tool.
  2. Download the VMware OS Optimization Tool VMware fling.
  3. Run the extracted VMwareOSOptimizationTool.exe.
  4. On the Optimize tab, choose a template.
  5. Then click Analyze on the bottom of the window.
  6. On the Optimize tab, review the optimizations, and make changes as desired. Then on the bottom left, click Optimize.
  7. The History tab lets you rollback the optimizations.
  8. The Finalize tab contains tasks that should be run every time you seal your master image.

Additional Optimizations

Additional Windows 10 Optimizations

Additional Windows 7 Optimizations

Microsoft has compiled a list of links to various optimization guides.

It’s a common practice to optimize a Windows 7 virtual machine (VM) template (or image) specifically for VDI use. Usually such customizations include the following.

  • Minimize the footprint, e.g. disable some features and services that are not required when the OS is used in “stateless” or “non-persistent” fashion. This is especially true for disk-intensive workloads since disk I/O is a common bottleneck for VDI deployment. (Especially if there are multiple VMs with the same I/O patterns that are timely aligned).
  • Lock down user interface (e.g. optimize for specific task workers).

With that said the certain practices are quite debatable and vary between actual real-world deployments. Exact choices whether to disable this or that particular component depend on customer requirements and VDI usage patterns. E.g. in personalized virtual desktop scenario there’s much less things to disable since the machine is not completely “stateless”. Some customers rely heavily on particular UI functions and other can relatively easily trade them off for the sake of performance or standardization (thus enhance supportability and potentially security). This is one of the primary reasons why Microsoft doesn’t publish any “VDI Tuning” guide officially.

Though there are a number of such papers and even tools published either by the community or third parties. This Wiki page is aimed to serve as a consolidated and comprehensive list of such resources.

Daniel Ruiz XenDesktop Windows 7 Optimization and GPO’s Settings

Microsoft Whitepaper Performance Optimization Guidelines for Windows 7 Desktop Virtualization

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:
  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. View Composer requires a snapshot.

This post applies to all VMware Horizon 7 versions, including 7.13.3.

💡 = Recently Updated

Change Log

Preparation

The newer Horizon Console does not support Security Servers. The older Flash-based Horizon Administrator won’t work for much longer, so take it as a clue that you should deploy Unified Access Gateways (UAG) to replace your Security Servers. Horizon 8 also does not support Security Servers.

Security Servers are intended to be deployed in the DMZ.

Horizon Security Server is installed on Windows. If you prefer a Linux appliance, see VMware Unified Access Gateway. Note: Some of the newer Blast Extreme functionality only works in Unified Access Gateway. See Configure the Blast Secure Gateway at VMware Docs.

Security Considerations for Horizon View 5.2 – http://www.vmware.com/resources/techresources/10371

Firewall Ports

If there is only one Security Server in the DMZ, create a NAT’d public IP to the Security Server. Create a public DNS entry that resolves to this IP address.

If your load balancer (e.g. NetScaler ADC, F5) is able to provide persistence across multiple port numbers, then you only need one public IP. For example, in NetScaler, this is called Persistency Groups.

If your load balancer doesn’t support persistence across multiple port numbers, then create three public IPs:

  • Public IP NAT’d to the load balancer IP. Create a public DNS entry that resolves to this IP address. This is the DNS name that users will enter into their Horizon Clients.
  • Public IP NAT’d to each of the Security Servers. Each Security Server must be exposed directly to the Internet. Create public DNS names that resolve to these public IPs. When installing Security Server, specify these public DNS names and not the load balanced DNS name.

Firewall Rules for View Connection Server at VMware Docs.

Open these ports from any device on the Internet to all Security Server and Load Balancer public IPs:

  • TCP 80
  • TCP and UDP 443
  • TCP and UDP 4172. UDP 4172 must be opened in both directions.
  • TCP and UDP 8443 (for Blast)

Open these ports from the Security Servers to internal:

  • If IPSec is enabled in View Administrator (Global Settings > Security > Edit), open ISAKMP Protocol (UDP 500) and ESP. Or if there is NAT between the Security Server and the Connection Server, open NAT-T ISAKMP (UDP 4500). Configuring a Back-End Firewall to Support IPsec at VMware Docs.
  • TCP 8009 (AJP13) to the paired internal Horizon Connection Server.
  • TCP 4001 (JMS) to the paired internal Horizon Connection Server.
  • TCP and UDP 4172 (PCoIP) to all internal Horizon Agents. UDP 4172 must be opened in both directions.
  • TCP 32111 (USB Redirection) to all internal Horizon Agents.
  • TCP and UDP 22443 (HTML Blast) to all internal Horizon Agents.
  • TCP 9427 (MMR) to all internal Horizon Agents.
  • TCP 4002 for Enhanced Messaged Security – Change the JMS Message Security Mode to Enhanced at VMware Docs

Pairing Password

The newer Horizon Console does not support Security Servers. The older Flash-based Horizon Administrator won’t work for much longer, so take it as a clue that you should deploy Unified Access Gateways to replace your Security Servers.

Horizon Consoles

On the desktop of the Horizon Connection Server is an icon to launch Horizon 7 Administrator Console.

Horizon 7.5 and newer have two administrator consoles:

  • Horizon Console (HTML5)
  • Horizon Administrator (Flex) – Flash-based

In Horizon versions 7.5 through 7.10, Horizon Console was not yet feature complete so most administrators continue to use the Flash-based Horizon Administrator. In these versions, you can access Horizon Console by navigating to https://viewConnectionServer/newadmin (add /newadmin to the end of your Connection Server FQDN). Or click the Horizon Console link at the top right of the Horizon Administrator console.

In Horizon 7.10 and newer, Horizon Console is feature complete and is now the primary administrator interface. The Flash-based Horizon Administrator is now deprecated.

In Horizon 7.11 and later:

  • When you connect to Horizon Administrator (/admin at the end of the Connection Server URL), you are prompted to choose between Horizon Console and Horizon Administrator. In prior versions of Horizon, going to /admin always opens the Flash-based administrator console.
  • If you navigate to /newadmin, it will redirect you to /admin where you can choose between the two consoles.
  • You can go directly to the Flash-based administrator console by navigating to /flexadmin.

Horizon Console 7.11 and newer’s Dashboard can show you the CPU/Memory of the Connection Servers:

  1. On the top left, expand Monitor and click Dashboard.
  2. On the right, in the top-left block named System Health, click VIEW.
  3. With Components selected on the left, the first tab on the right is Connection Servers. It shows you a list of Connection Servers in the pod and each server’s CPU and Memory Consumption.

Licensing

As of Horizon 7.9, Horizon Licensing can be configured in either the new HTML5-based Horizon Console or the classic Flash-based Horizon Administrator.

  1. Open Horizon Console or Horizon Administrator.
  2. Login using a Horizon administrator account.

  3. In Horizon Console on the left, expand Settings and click Product Licensing and Usage.

    1. Or in Horizon Administrator, on the left, under View Configuration, click Product Licensing and Usage.
  4. In the right pane, on the top left, click Edit License.

  5. In the Edit License window, enter your license serial number, and click OK.
  6. Licensing information is displayed:
    • License expiration is shown.
    • Application Remoting (published applications) requires Horizon Advanced Edition.
    • Skype Optimization requires Horizon Advanced Edition.
    • In Horizon 7.13, Instant Clones are available in all editions of Horizon. Prior to 7.13, Instant Clones requires Horizon Enterprise Edition.
    • Session Collaboration requires Horizon Enterprise Edition.
    • Help Desk tool requires Horizon Enterprise Edition.

Horizon Administrators

To configure Horizon Administrators:

  1. In Horizon Console 7.8 or newer, on the left, expand Settings, and click Administrators.

    • Or in Horizon Administrator, on the left, expand View Configuration, 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). Newer versions of Horizon include a built-in Help Desk Administrators role, 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.
    • Note: If you intend to integrate Horizon with VMware Identity Manager (aka VMware Access), then only pools in the Root Access group will sync with Identity Manager. Other Access Groups won’t work.

Help Desk Website

Horizon 7.2 and newer have a new web-based Help Desk tool built into Horizon Connection Server.

  • In Horizon Console (Horizon 7.5 and newer), simply enter a user name in the search box.
  • VMware also has an alternative Horizon Helpdesk Utility Fling
  • For Horizon 7.2 through 7.4, go to https://HorizonFQDN/helpdesk (e.g. https://view.corp.com/helpdesk).

The Desktops and Applications tabs let you see what the user it 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. In Horizon 7.3 and newer, the Product Licensing page indicates if Help Desk is licensed or not.

  • In Horizon 7.2, only Full Horizon Administrators can login to the Help Desk web page.
  • Horizon 7.3 and newer have built-in Help Desk Administrators roles that can log into 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. Use vRealize Operations for Horizon for longer historical monitoring.
  • See Rob Beekmans Helpdesk functionality added to VMware Horizon 7.2.
  • According to Pascal van de Bor Horizon 7.2: With a little helpdesk from my friends, checkOrigin needs to be disabled to prevent the “Authentication failed, invalid domain, username or password. Please try again” error.

See Troubleshooting Users in Horizon Help Desk Tool at VMware Docs.

vCenter Connection, and optional Horizon Composer

Horizon must connect to vCenter for several reasons:

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

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 Web Client, go to the vCenter Server > Manage > Settings > General > Edit > Runtime Settings, and confirm that the ID is unique for each vCenter server.

  1. In Horizon Console 7.8 or newer, on the left, expand Settings, and click Servers.

    • Or in Horizon Administrator, on the left, expand View Configuration, 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. Click Next.

  5. If you see a message regarding invalid certificate, click View Certificate. Then click Accept.


  6. In the View Composer page, if you are using Horizon Composer, then do the following:
    1. Select Standalone View Composer Server.
    2. Enter the FQDN of the Composer Server, and the credentials of an account to access the Horizon Composer server. The service account must be a local administrator on the Horizon Composer Server.
  7. Click Next.

  8. If you see an invalid certificate, click View Certificate. Then click Accept.


  9. If you are using Horizon Composer, then in the View Composer Domains page, do the following:
    1. Click Add.

    2. Enter the Full domain name of where the virtual desktop computer objects will be created.
    3. Enter the Active Directory service account credentials that has permission to create computer objects, and click Submit.

  10. Then click Next.
  11. In the Storage page, do the following:
    1. Reclaim VM disk space requires IOPS during its operation. This feature is not needed for Instant Clones.
    2. Check the box to Enable Horizon Storage Accelerator, and increase the host cache size to 2048. Notes:
      • Horizon Storage Accelerator is required for Instant Clones.
      • Horizon Storage Accelerator causes digest files to be created, thus increasing disk space requirements and increasing how long it takes to Recompose a pool.
  12. Click Next.

  13. 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 7.9 or newer, on the left, expand Settings and click Instant Clone Domain Accounts.

    • Or in Horizon Administrator, on the left, expand View Configuration, and click Instant Clone Domain Accounts.
  2. On the right, click Add.

  3. Select the domain.
  4. Enter credentials of a service account that can join machines to the domain. Click OK.

Disable Check Origin

If you connect to Horizon Connection Server using any DNS name (e.g. load balancing DNS name) that doesn’t match the server’s DNS name, then it might not work unless you disable Origin Check as detailed at VMware 2144768 Accessing the Horizon View Administrator page displays a blank error window in Horizon 7.

Restrict Remote Access

The Users and Groups node has a new Remote Access tab. You can configure this in either the Horizon Console or in Horizon Administrator.

If you add groups or users to this tab, only these groups and users can login through Unified Access Gateway (UAG) or Security Server.

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

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 in either Horizon Console or Horizon Administrator:

  1. In Horizon Console, on the left, expand Settings, and click Servers.

    • Or in Horizon Administrator, on the left, expand View Configuration, 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 two Gateways. Click OK.
  5. Note: if you are using HTML5 Blast internally, then disabling the Blast Secure Gateway will cause HTML5 Blast connections to go directly to the Horizon Agent, and the Agent certificate is probably not trusted. Newer versions of Horizon have an option to use Blast Secure Gateway only for HTML Access.

Event Database and Syslog

  1. In Horizon Console 7.9 or newer, on the left, expand Settings and click Event Configuration.

    • Or in Horizon Administrator, expand View Configuration, 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.
    3. Enter the name of the database.
    4. Enter the SQL account credentials (no Windows authentication).
    5. Optionally, enter VE_ (or similar) for the Table prefix. This allows you to use the same Events database for multiple View installations.
  4. Click OK.

  5. 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.

  6. To add a Syslog server, look on the right side of the page.

  7. There are configuration options for logging to a file (Events to File System).

  8. You can go to Monitor > Events to view the events in the database.

Event Database SQL Index

VMware Knowledgebase article – The Event database performance in VMware View 6.0.x is extremely slow (2094580): Symptoms:

  • The Event database performance in VMware View 6.0.x is extremely slow when browsing within View
  • High CPU usage on the SQL server, hosting the Event database
  • The larger the Event database becomes, the slower the queries run.

To resolve this issue, create an index. Run this command on your SQL Event database:

CREATE INDEX IX_eventid ON dbo.VDIevent_data (eventid)

Substitute VDIevent_data for the table name using your Event database prefix.

Event Queries

VMware Fling – 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 – VMware 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.

VMware Knowledgebase article – Creating SQL views to retrieve the top 50 maximum number of concurrent desktop sessions over a period: This article provides steps to create database views to retrieve the maximum number of concurrent desktop sessions over a period from the event_historical table.

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 7.9 or newer, on the left, expand Settings and click Global Settings. Or in Horizon Administrator, on the left, under View Configuration, click Global Settings.

  2. On the right, under Global Settings, in the General Settings tab (or General section), click Edit.

  3. Set the Connection Server Session Timeout (7.13 only) or View Administrator session timeout, which applies to both administrators and help desk. 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.

  5. Under Client-dependent settings you can set an idle timeout. This is a disconnect, not logoff.

  6. To configure 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 Administrator.

  8. In Horizon 7.8 and newer, the Send domain list option in Horizon Console and Horizon Administrator is unchecked by default, which means users must enter a domain name instead of picking one from a list. Check this box to restore functionality from Horizon 7.7 and earlier. See VMware Blog Post Changes in Logon for VMware Horizon. Note: This setting is configurable in Horizon Console 7.10 and newer.

  9. Make other changes as desired. Click OK when done.
