Hi David,
You can delete the VM from the DB using this command:
SELECT DeleteVm('<vm-id>');

Hello,
This seems to be what the engine is trying to do, and failing at for some
reason.
eg:
[root@ovirt-node217 ~]# vdsm-client Host getVMList fullStatus=True
[
"8b3964bc-cd3f-4f13-84c6-1811193c93eb",
"132668b6-9992-451f-95ac-dbcbeb03f5f1"
]
For reference:
[root@ovirt-node217 ~]# virsh -r list --all
Id Name State
----------------------------------------------------
- vm-s2 shut off
- vm-s1 shut off
And in the console, it shows a count of "2" beside this host, but on the
host detail
page, under the virtual-machine tab, the list is empty (these VMs are
actually
running on a different host).
[root@ovirt-node217 ~]# vdsm-client VM destroy
vmID="8b3964bc-cd3f-4f13-84c6-1811193c93eb"
vdsm-client: Command VM.destroy with args {'vmID':
'8b3964bc-cd3f-4f13-84c6-1811193c93eb'} failed:
(code=100, message=General Exception: ("'1048576'",))
I guess what I need is a way to remove/clean-up these VMs manually since
ovirt
does not seem to be able to do it by itself.
This condition also blocks the host from being put into maintenance mode.
When I reboot the host manually and "confirm host was rebooted", the VMs
are still there and still stuck.
Sincerely,
David

Hi,
You can try with the vdsm-client tool:
https://www.ovirt.org/develop/developer-guide/vdsm/vdsm-client.html
Stopping a VM:
1) Get the vmId:
# vdsm-client Host getVMList fullStatus=True
2) Destroy the VM
# vdsm-client VM destroy vmID=<vmID>
