Home Server

A home server is the server which provides the resources for a VM in a pool. When you nominate a home server for a VM, XenServer always attempts to start up the VM on that server if it can. If XenServer cannot start the VM on that server, an alternate server within the same pool is selected automatically.

  • To nominate a home server for the VM in the New VM wizard, select Place the VM on this server and choose a server from the list.
  • If you do not want to nominate a home server, click Don’t assign this VM a home server. The VM uses the resources on the most suitable available server.

If you are creating a BIOS-customized VM, the OEM server from which you copy the BIOS strings is automatically selected as the home server for the new VM.

You can change the home server configuration for a VM from the VM’s Properties dialog box; see Change VM properties.

Workload Balancing (WLB) and Virtual GPU considerations

The following section lists scenarios when the home server nomination does not take effect:

  • In pools with Workload Balancing (WLB) enabled, the nominated home server is not used for starting, restarting, resuming, or migrating the VM. Instead, WLB nominates the best server for the VM by analyzing XenServer resource pool metrics and by recommending optimizations.
  • If a VM has one or more virtual GPUs assigned to it, the home server nomination does not take effect. Instead, the server nomination is based on the virtual GPU placement policy set by the user. For more information, see GPU Placement Policy.
