Ok, now that I'm able to (re)deploy ovirt to new hosts, I now need to migrate VMs that are running on hosts that are currently in an "unassigned" state in the cluser.

This is the result of having moved the oVirt engine OUT of a hyperconverged environment onto its own stand-alone system, while simultaneously upgrading oVirt from v4.4 to the latest v4.5.

See the following email threads: 

The oVirt engine knows about the VMs, and oVirt knows about the storage that those VMs are on. But the engine sees 2 of my hosts as "unassigned", and I've been unable to migrate the disks to new storage, nor live migrate a VM from an unassigned host, nor make a clone of an existing VM.

Is there a way to recover from this scenario? I was thinking something along the lines of manually shutting down the VM on the unassigned host, and then somehow force the engine to bring the VM online again from a healthy host?

Thanks,
David
