We have a new Win2008 R2 Failover cluster with 3 nodes and a set of 30+ VM's exported from a series of stand alone Hyper-V hosts. Each VM has between 6 and 30 snapshots. All hosts and VM's have the same virtual network name. When imported on a cluster node all network settings are ok and all snapshots work.
If we move or migrate a VM to another node than where it was imported, all snapshots on the VM show a configuration error on their network adapter. The guest OS has no network anymore and the snapshot config does not allow for it to be changed.
What is the point of migrating anything if it break everything that isn't running on its original host? How can I fix this?
