Hi,
The issue started prior to the host being rebooted intentionally.
But I did mark It as rebooted after I restarted the host.
I have observed that the VMs status in the Dashboard GUI was not reflecting the actual
status of the VMs when viewed from the Host CLI.
It seems restarting the ovirt-engine service in HE solved the problem.
When I place any host in maintenance mode, I no longer see the error below and VMs are
migrating now without problems.
