Hi Juan,
That sounds like a possible path to follow. Our "master" domain does not
have any VMs in it. If no one else responds with an official path to
resolution, then I will try going into the database and hacking it like
that. I think it has something to do with the version or the metadata??

Hello Tommy,
I had a similar experience and after try to recover my storage domain, I
realized that my VMs had missed. You have to verify if your VM disks are
inside of your storage domain. In my case, I had to add a new a new Storage
domain as Master domain to be able to remove the old VMs from DB and
reattach the old storage domain. I hope this were not your case. If you
haven't lost your VMs it's possible that you can recover them.
Good luck,
Juanjo.
