Restoring Full Virtual Machines for Citrix Xen

You can restore one or more Xen virtual machines (VMs) at a time. Virtual machines can be restored in place (to the source virtual machines) or out of place (with a different virtual machine name, or to a different XenServer or Xen pool).

When browsing virtual machines for a restore, the default is a full machine restore.

When restoring virtual machines to a different Xen pool, provide root user credentials or a user account having the Pool Administrator (Pool Admin) role to access the master XenServer in the destination Xen pool.

Restore Considerations

  • For full virtual machine restores, network connections are not restored. You must attach the network card manually after the restore.

  • CD-ROM drives are not attached to a virtual machine after a restore.

  • If a virtual machine is added to subclient content or to a filter by browsing and selecting the VM display name, discovery is performed based on the GUID for the VM.

    If that virtual machine is later restored in place from a backup, a new GUID is generated, and that virtual machine is no longer identified correctly. To identify that VM, you must remove the old rule, then add a new rule or use a name pattern to select the VM.

  • To perform an in-place restore of a virtual machine with the Unconditionally overwrite VM with the same name option, Xen integration services must be installed on the VM. If integration services are not installed on the VM, you can manually delete the original VM before performing the restore.

Procedure

  1. From the CommCell Browser, expand Client Computers > virtualization_client > Virtual Server > instance > backup_set.

  2. Start the restore from a subclient or backup set:

    • From a subclient: Right-click the subclient and then select Browse and Restore.

    • From a backup set: Right-click the backup set, point to All Tasks, and click Browse and Restore.

  3. In the Browse and Restore Options dialog box, ensure that the Full Virtual Machine option is selected, and then click View Content.

  4. From the list of backed up virtual machines, select one or more virtual machines to be restored, and then click Recover All Selected.

  5. From the list of backed up virtual machines in the Client tab, select one or more virtual machines to be restored and click Recover All Selected.

    The Restore VM wizard launches and displays the Destination page.

  6. Specify the destination and the proxy to be used for the restore.

    By default, VMs are restored in place to the original location for the source VM, and the restore is performed using the preferred VSA proxy for the virtualization client.

    • In Place: To restore a virtual machine out of place, clear this check box.

    • XenPool: To restore to a different Xen pool, select the Xen pool client from this list.

      To add a new client, select Add new XenServer, and then specify the XenServer information and user credentials. You can enter a host name, fully qualified host name, or IP address for a standalone XenServer or for the master XenServer in a Xen pool.

    • Instance Details: Shows the XenServer and user account for the selected XenPool.

    • Proxy client: By default, the proxy that performed the backup is used for the restore. If you change this value, the proxy client must reside on a XenServer in the Xen pool that has direct access to the destination storage repository.

      Only proxies that match the type of the virtualization client are displayed.

      Note

      When creating a Xen virtual machine to be used as a VSA proxy, ensure that the Copy host BIOS strings to VM option is not selected. If the Copy host BIOS strings to VM option was selected when a Xen virtual machine was created, the virtual machine will not be recognized as a Xen proxy.

  7. Click Next.

    The wizard displays the Virtual Machines page.

  8. For an out-of-place restore, specify parameters for the restore:

    • VM and Disk: This column shows the source virtual machines with disks underneath each virtual machine.

    • Change VM display name to: Enter the new display name for the virtual machine.

    • Xen Server: Click in the row for the XenServer name, click ..., select the new XenServer, and then click OK.

    • Storage Repository: Select the storage repository from the list.

      If necessary, you can select a different storage repository for each virtual machine disk.

  9. Click Next.

    The wizard displays the Restore Options page.

  10. Optional: Select restore options:

    • Power ON Virtual Machine after Restore: Select this check box to start the virtual machine automatically after the restore is complete.

    • Unconditionally Overwrite VM with the same name: Select this check box to replace any existing virtual machines with the same names in the target location.

      Note

      If you do not select this check box when restoring a virtual machine to a location that has a VM with the same name, the restore fails.

  11. Click Next.

    The wizard displays the Job Options page.

  12. Run the job immediately or configure a schedule for the restore.

  13. Click Next.

    The wizard displays a Summary page for the restore.

  14. To further customize the restore operation, click Advanced.

    For more information about advanced options, see Advanced Restore Options.

  15. Click Finish to submit the restore job.
