Hi,

there are two major sources of information you need to debug this. All
come from the hosts themselves:

hosted-engine --vm-status - the current status of the cluster, should
be the same on both hosts, but can differ if something is wrong with
the synchronization
/var/log/ovirt-hosted-engine-ha/{agent.log,broker.log} - the log files

The usual reason for migrating (well stopping and starting) the VM are
issues with pinging the configured gateway or crash of the VM.

Best regards

Martin Sivak
