XenServer virtualization environments

Create a connection to XenServer

When you create a connection to XenServer, you must provide the credentials for a VM Power Admin or higher-level user.

Citrix recommends using HTTPS to secure communications with XenServer. To use HTTPS, you must replace the default SSL certificate installed on XenServer; see CTX128656.

You can configure high availability if it is enabled on the XenServer. Citrix recommends that you select all servers in the pool (from Edit High Availability) to allow communication with XenServer if the pool master fails.

You can select a GPU type and group, or pass through, if the XenServer supports vGPU. The display indicates if the selection has dedicated GPU resources.

When using local storage on one or more XenServer hosts for temporary data storage, make sure that each storage location in the pool has a unique name. (To change a name in XenCenter, right-click the storage and edit the name property.)

Use IntelliCache for XenServer connections

Using IntelliCache, hosted VDI deployments are more cost-effective because you can use a combination of shared storage and local storage. This enhances performance and reduces network traffic . The local storage caches the master image from the shared storage, which reduces the amount of reads on the shared storage. For shared desktops, writes to the differencing disks are written to local storage on the host and not to shared storage.

  • Shared storage must be NFS when using IntelliCache.
  • Citrix recommends that you use a high performance local storage device to ensure the fastest possible data transfer.

To use IntelliCache, you must enable it in both this product and XenServer.

  • When installing XenServer, select Enable thin provisioning (Optimized storage for XenDesktop). Citrix does not support mixed pools of servers that have IntelliCache enabled and servers that do not. For more information, see the XenServer documentation.
  • In Citrix Virtual Apps and Desktops, IntelliCache is disabled by default. You can change the setting only when creating a XenServer connection; you cannot disable IntelliCache later. When you add a XenServer connection:
    • Select Shared as the storage type.
    • Select the Use IntelliCache check box.

Create a machine catalog using a XenServer connection

GPU-capable machines require a dedicated master image. Those VMs require video card drivers that support GPUs. Configure GPU-capable machines to allow the VM to operate with software that uses the GPU for operations.

  1. In XenCenter, create a VM with standard VGA, networks, and vCPU.
  2. Update the VM configuration to enable GPU use (either Passthrough or vGPU).
  3. Install a supported operating system and enable RDP.
  4. Install XenServer Tools and NVIDIA drivers.
  5. Turn off the Virtual Network Computing (VNC) Admin Console to optimize performance, and then restart the VM.
  6. You are prompted to use RDP. Using RDP, install the VDA and then restart the VM.
  7. Optionally, create a snapshot for the VM as a baseline template for other GPU master images.
  8. Using RDP, install customer-specific applications that are configured in XenCenter and use GPU capabilities.
