I have a Hyper-V Failover Cluster where Failover Cluster Manager (FCM) is behaving very strangely.
The FCM GUI shows several VMs changing state rapidly (from Running -> paused -> resume -> running in a very rapid cycle). When I say rapidly, its happening so fast the right-click menus are flickering. FCM responsiveness is also sluggish.
These same VMs are shown as running fine and not changing state in Hyperv Manager.
Does anyone have any suggestions as to what to look for? I'm assuming it's some communication issue.
