Hi,

    Got a problem with oVirt 4.2

While putting a Host in maintenance mode, an VM has failed to migrate.
The end state is that the Web UI shows the VM as "Migrating from".

The VM is not running in any Host in the cluster.

This is the relevant message in the /var/log/ovirt-engine/engine.log

I already tried canceling the migration, powering off the VM, restarting
the engine service and restarting the vdsm on the host which is supposed
to have that VM. No success so far. unlock_entity.sh shows no locked
entities.

Can somebody help on how to recover from this?

Thanks!
