Create an Automated Full-Clone Linux Desktop Pool

You can create an automated full-clone desktop pool from Linux virtual machines. After you create the automated full-clone desktop pool, you can use the Linux virtual machines as remote desktops in a Horizon 8 deployment.

The following procedure provides guidelines for configuring the mandatory settings for a Linux-based automated full-clone desktop pool. For more information about creating automated full-clone desktop pools, see the Windows Desktops and Applications in Horizon document.

Prerequisites

• Verify that you have prepared a virtual machine for cloning. See Preparing a Linux Virtual Machine for Desktop Deployment.
• Verify that Horizon Agent is installed on the Linux guest operating systems. See Install Horizon Agent on a Linux Virtual Machine.
• If you use the Winbind solution to join the Linux virtual machine to Active Directory, you must finish configuring the Winbind solution in the virtual machine template.
• If you use the Winbind solution, you must run the domain join command on the virtual machine. Include the command in a shell script and specify the script path to the Horizon Agent option RunOnceScript in viewagent-custom.conf. For more information, see Setting Options in Configuration Files on a Linux Desktop.
• Verify that vCenter Server is added to Horizon Connection Server.

Procedure

1. Create a guest customization specification.

   See "Create a Customization Specification for Linux" in the vSphere Virtual Machine Administration document, available in the vSphere Documentation. When you create the specification, make sure that you specify the following settings correctly.

   Setting	Value
   Target Virtual Machine OS	Linux
   Computer Name	Use the virtual machine name.
   Domain	Specify the domain of the Horizon 8 environment.
   Network Settings	Use standard network settings.
   Primary DNS	Specify a valid address.

   Note: For more information on operating system release support details for vCenter's Guest OS Customization feature, see Knowledge Base (KB) article 85845.

2. In Horizon Console, add an automated desktop pool.

   Select Inventory > Desktops > Add.

3. Select Automated Desktop Pool and click Next.

4. Select Full Virtual Machines, select the vCenter Server instance, and click Next.

5. Follow the prompts in the wizard to create the pool.

   1. On the Desktop Pool Settings page, set the following options.

      Option	Description
      Default display protocol	Horizon Blast
      Allow users to choose protocol	No
      3D Renderer	Manage using vSphere Client for 2D desktop and NVIDIA GRID vGPU for 3D desktop
      Session Types	You can enable the VM Hosted Applications feature by selecting the supported session type for the desktop pool: Desktop. Select this option to use the pool as a regular desktop pool. All the virtual machines in the pool can only be used to host desktops. Application. Select this option to use all the virtual machines in the pool to host applications. Desktop and Application. When this option is selected, the virtual machine in the pool can either host a regular desktop session or host an application session. The first connection to the particular virtual machine will determine the session type of the virtual machine. For more information about the VM Hosted Applications feature, see the technical marketing white paper "Best Practices for Published Applications and Desktops in Horizon and Horizon Apps" available at https://techzone.omnissa.com.

   2. When prompted, set the Virtual Machine Naming options.

      Option	Description
      Specify names manually	Enter names manually.
      Naming Pattern	For example, specify LinuxVM-{n}. You must also specify the following desktop pool sizing options: Maximum number of machines Number of spare, powered-on machines

   3. When prompted, select the vCenter Server settings in sequence.

      You cannot skip a vCenter Server setting:

      1. Template
      2. VM folder location
      3. Host or cluster
      4. Resource pool
      5. Datastores

6. After creating the desktop pool, entitle users to the machines in the desktop pool. In Horizon Console, select the desktop pool, select Entitlements > Add entitlement, and add users or groups.

7. Wait until all the Linux virtual machines in the desktop pool become available.
