Shit, I got it. Sorry

The problem is that I was accessing to the v4 disk-attachment id and I was getting everything quite messed up. I was doing all of this while creating a machine, so I was trying to rename the disk at the same time it's being created.

I'll delete all the "if ($ovirt_major == 3)" I have in my code. If I have any problem I'll let you know.

Thank you

That should work. Can you please check if you get any useful message in
/var/log/ovirt-engine/server.log or /var/log/ovirt-engine/engine.log?
