Microsoft Hyper-V Server 2008 R2: Using Live Migration

Microsoft® Hyper-V™ Server 2008 R2 is the next generation of Microsoft Hyper-V Server 2008. It includes support for failover clustering, including live migration, to accommodate both planned and unplanned downtime. This guide details the steps required to perform a live migration of Hyper-V virtual machinesfrom one node in a failover cluster to another node.

Live migration overview

Hyper-V and failover clustering can be used together to make a virtual machine that is highly available, thereby minimizing disruptions and interruptions to clients. Live migration requires the failover clustering feature to be added and configured on the servers running Hyper-V and allows you to transparently moverunning virtual machines from one node of the failover cluster to another node in the same cluster without a dropped network connection or perceived downtime. To perform the steps in this guide, the nodes in the cluster can consist of a mix of servers running Microsoft Hyper-V Server 2008 R2 and servers running the Server Core installation option of Windows® Server 2008 R2. It is possible to performa live migration of virtual machines between those nodes.
Failover clustering requires shared storage for the cluster nodes. This can include an iSCSI or Fiber-Channel Storage Area Network (SAN). All virtual machines are stored on the shared storage, and the running virtual machine state is managed by one of the nodes.
