A monitor can be overridden to change the virtual machine move mode such as QuickMove or LANMove. QuickMove is restricted to cluster-based hosts and is designed to use for critical state situations. To change the move mode, go to the Diagnostic and Recovery tab in the Properties view of the monitor, select Edit, and then override MoveMode to replace string (QuickMove or LANMove) for both Diagnostic task and Recovery task.
Windows 2008 R2 Hyper-V servers now have the live migration feature. The VM is live migrated if the cluster-based hosts are configured with Windows 2008 R2 Hyper-V. The VMM automatically determines its live migration capability on the clustered-host and selects live migration, if applicable.
