<div>In our old 3.4 ovirt, I know I've migrated storage on live VMs and everything
<br>
seemed to work.<br>
<br>
However on 3.6.6, I tried this and I saw the warning about moving storage on a <br>
live VM (it wasn't doing much of anything) and I went ahead and migrated the <br>
storage from one storage domain to another. But when it was through, even <br>
though the VM was still alive, when I tried to write to a virtual disk that was <br>
part of the move, it paused the VM saying there wasn't enough storage.<br>
<br>
I could unpause the VM, but in a few seconds, with things writing to the virtual <br>
disk, again it was paused with the same out of space message. Vdsm logs showed <br>
the enospc return code... so it made sense, it's just that the VM shows plenty <br>
of storage there. Once I rebooted the VM, everything went back to normal.<br>
<br>
So is moving storage for a live VM not supported? I guess we got lucky in our <br>
3.4 system (?)<br>
