[ovirt-users] took the plunge to 4.2 but not so sure it was a good idea

I reinstalled "dist" because I needed the VM to be accessible on the 
network.  I was going to try detatching the disk from the existing dist 
server, and attaching it to a new dist VM, but I ended up inadvertently 
deleting the disk image.  I can't believe that under "storage" you can't 
detatch a disk from a VM - you can only delete the disk.

After reinstalling dist, I got back console, and network access!  I 
tried rebooting it several times, and console remains... so the loss of 
console has something to do with switching from a 4.1 VM to 4.2.

I rebooted one more VM for which I had console access, and again, I've 
lost it (at least network access remains). Now that this situation is 
repeatable, I'm going one of the ovirt gurus can send me the magical DB 
command to fix it.    Probably not a solution to reinstall my 37 VMs 
from kickstart.. that would be a headache.

The error in engine.log when I try to update any of the hosts is:
