• If you cluster your virtual machines and then use Hyper-V Manager to change the configuration of one of those virtual machines, be sure to follow the procedure described in this topic. Otherwise, the settings of the virtual machine might not be up-to-date in the failover cluster, which could cause problems during the next move, migration, or failover of that clustered virtual machine.
  • We recommend that you use Failover Cluster Manager instead of Hyper-V Manager when you change the settings of a clustered virtual machine. For more information, see Modify the Virtual Machine Settings for a Clustered Virtual Machine.
To refresh the configuration of a virtual machine
  1. In the Failover Cluster Manager snap-in, if the cluster that you want to configure is not displayed, in the console tree, right-click Failover Cluster Manager, click Manage a Cluster, and then select or specify the cluster that you want.

  2. If the console tree is collapsed, expand the tree under the cluster that you want to configure.

  3. Expand Services and Applications, and then click the virtual machine for which you want to refresh the configuration.

  4. In the Actions pane, scroll down, click More Actions, and then click Refresh virtual machine configuration.

  5. Click Yes to view the details of this action.

Additional considerations

  • You can also perform the task described in this procedure by using Windows PowerShell. For more information about using Windows PowerShell for failover clusters, see and

  • To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Manager. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
