It looks like the VM is hang.
Do you have the ACPI Feature enabled in the VM Template and the acpid service running inside the VM?
Nope. Neither was enabled. However, the VM was still responding to my keystrokes. Wasn’t hung.
To resolve this you could take a look at /var/lib/one/remotes/etc/vmm/kvm/kvmrc . Check SHUTDOWN_TIMEOUT and FORCE_DESTROY variables.
I manged to nudge it back into a POWEROFF state. I did a virsh destroy one-27. At this point I could see it in POWEROFF state in the UI. I did all this so I can change the VM boot order using:
onevm updateconf 17
( Only possible in POWEROFF mode. )
Hope this helps.
