Q: How do I configure the network to use Live Migration in a Windows Server 2012 Failover Cluster?

A. Typically the network selection for a Hyper-V host is configured via the Hyper-V host setting; however, this setting is overridden by the cluster configuration. To configure the networks to use for Live Migration, perform the following:

  1. Launch Failover Cluster Manager.
  2. Right-click Networks and select Live Migration Settings...
  3. Select the networks to use for Live Migration and reorder as required, then click OK.

The settings will be applied to the Hyper-V hosts and will be visible in the Hyper-V settings window. You'll be notified that the migration settings can't be modified as they are in use by a cluster.
