Figure 26. Adding a new VM to a Failover Cluster – Review the VM settings summary
The Summary screen allows you to confirm the virtual machine settings before you deploy the virtual
machine to the selected host. If the host is a Microsoft Hyper-V system, the deployment process will
automatically install the Hyper-V Integration Components in the new VM.
Reducing Planned Downtime with Live Migration
Live Migration enables an administrator to move virtual machines between Hyper-V hosts with no
downtime and no loss of services for the end users of those virtual machines, and to perform scheduled
maintenance on Hyper-V hosts, again with no downtime for the virtual machines running on that host.
When combined with the VMM PRO feature, Live Migration can also dynamically move virtual
machines to different Hyper-V services in response to the resource utilization of the Hyper-V host or the
virtual machine. Live Migration is only available with Windows Server 2008 R2. It is enhanced by
Windows Server 2008 R2’s new Clustered Shared Volumes (CSV) feature. CSV enables multiple
cluster nodes to concurrently access the virtual machine files stored on the same LUN. The following
section outlines an example of how to create a virtual machine configured for Live Migration and how to
use VMM to initiate a Live Migration.
