Hi,
I just had the same problem again. - Stopped oVirt engine - Checked the 'async_tasks' table. It was empty! - Started oVirt engine - Same set of imported VMs as last time deleted!
I thought that lingering records from the 'async_tasks' table were to blame, but apparently, that's not the case.
Can you tell me what I need to check/do/modify/update/delete before restarting oVirt that will keep my VMs from being deleted? (Please see below for a note on upgrading like you suggested)
make sure you dont have records at async_tasks with vdsm_task_id of "empty guid" - but i'm really not in favor of such hacks, this is a hack. I strongly suggest you solve upgrade issue (please communicate with ofer on this).
OK, I understand that, but for the record: 'async_tasks' was completely empty before I started Engine, so this hack wouldn't have been of any use. Cheers, Martijn.
