Overview: In this white paper, we begin with an introduction to quick migration of virtual machines using the Hyper-V technology. We then describe how to apply Hyper-V's quick migration to enhance the availability of services. We explore how you can prepare for planned downtime by using quick migration to save the state of a running virtual machine, move the storage connectivity from one physical server to another, and then restore the virtual machine (for unplanned downtime, the virtual machine is failed over automatically and the state is not saved). We examine a specific scenario, assuming that Windows Server® 2008 Enterprise or Windows Server® 2008 Datacenter is already installed. We explain how to set up the failover clustering service, how to configure Hyper-V, and how to use quick migration to fail over a workload and maintain services.
