Thanks. Sorry for the late replay but I had to travel. I've tried your suggestion and
now I'm not able to start the engine VM. It's trying to get access for a storage
(that I can't tell which is as vdsm only shows the ID and I don't have a way to
know the label without the engine).
I think that I might need to hack into the database of the engine or reset it and hack in
the backup so I can change some values by hand.
Any other ideas?
