Restored virtual machine is not a part of the failover cluster

Article ID: HPV0021 After a restore operation, the restored virtual machine is not part of the failover cluster.


The restored virtual machine is not registered with the failover cluster.


Cause 1:

The Register Virtual Machine with Failover Cluster option was not selected during the restore operation.

Cause 2:

The user name given during registration is different from what was specified for the virtualization client.

Cause 3:

UAC is enabled on a Virtual Machine running on 2008 R2 Hyper-V server.


Resolution 1:

Make sure that the Register Virtual Machine with Failover Cluster check box is selected in the Restore Options for All Selected Items dialog box.

Resolution 2:

Make sure that the user name specified during the creation of a virtualization client is part of the following administrator groups on the Hyper-V host:

  • Cluster Administrators group
  • Hyper-V Administrators group
  • Local Administrators group (for Windows Hyper-V Server 2008 R2)

    You must have full access to the WMI namespace on all Hyper-V hosts involved in the backup. For acquiring the required privileges, complete the following steps:

  1. From the Start menu, type Run.
  2. In the Open box, type wmimgmt.msc and click OK.
  3. In the Console Root, right-click  WMI Control (Local) > Properties.
  4. On the Security tab, click Security.
  5. Under Permissions for Administrators, click Allow for the required permissions 

Resolution 3:

If the UAC (User Account Control) is enabled on the 2008 R2 Hyper-V server, manually register the Virtual Machine running on the Hyper-V server with the failover cluster.
