Microsoft Hyper-V Server 2008 R2 includes Live Migration and High Availability. Period. No Strings Attached.
Live Migration is a great solution for planned downtime such as servicing the underlying hardware like adding more memory, storage or applying a BIOS update. Simply Live Migrate the virtual machines to another server (without downtime) shutdown the physical server and perform the maintenance. When the maintenance is complete, Live Migrate the virtual machines back and your done.
High Availability is a great solution for unplanned downtime. For example, suppose someone accidentally unplugs the wrong power cable on a server. The virtual machine on the server that just unexpectedly went down will automatically restart on another node without any user intervention.
Hyper-V Server 2008 R2 includes both these capabilities as well as our new Cluster Shared Volumes (CSV) capabilities to simplify storage management and run multiple virtual machines from a single LUN.
