This could be a blue-screen error or a power outage. The second is network isolation. In this state, the host is still up, but it is not available.

Another failover trigger is the failure of a monitored service, as described in Chapter 10, Maintaining and Monitoring a Hyper-V Server Cluster. In this case, the cluster's first response is to try to restart the guest on the same node. Its second response is to move it to another node, much as it would if that guest's host became isolated.
