Hello,
I've somehow gotten one of my VMs stuck in a state that ovirt seems to be
rather confused about its
existence of now. I'm running oVirt 4.3.10 and using oVirt Node on all the
hosts.
My engine and host event logs are now filling up very rapidly with this error:
VDSM node217 command DestroyVDS failed: General Exception: ("'1048576'",)
I was playing with hugetable support, and that error number or string looks
suspiciously
like the "hugetable size" custom property I set on the VM.
This VM was migrated to another host at one point as well, and now that host is
also
generating the same error as well.
When I try to move these hosts to maintenance mode, they get stuck in
"Preparing for
Maintenance" while it tries to migrate/deal with the VM that's not there any
more.
Forcibly rebooting the hosts does not change anything. The VM state/host seems
to be
captured somewhere persistent in this case.
The VM in question is not running, and I can start it up on another host
successfully,
but ovirt still thinks it exists on the other 2 hosts no matter what I do.
Is there perhaps some way to delete it from the engine database directly to
straighten
things out?
Here's a dump of the vdsm log on one of the hosts. I haven't been able to
pinpoint what
the exact issue is or how to fix it, but hopefully someone here will have seen
this before?
