KVM vms are paused and cannot be deleted due to hardware error 0x0

[Anastasiia Naboikina]

Upon creation of instances via OpenStack nova api instances got stuck in spawning state. Then, after trying to delete instances they got stuck in deleting state. After investigation the following error was found:

All instances were in paused state:
root@node-7:~# virsh list
setlocale: No such file or directory
 Id Name State
----------------------------------------------------
 4 instance-00000004 paused
 5 instance-00000005 paused
 6 instance-00000006 paused
 7 instance-00000007 paused
 8 instance-00000008 paused
 9 instance-00000009 paused

The only way to delete VM is to reset it and then resume it. After this, VM is deleted properly.

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks Thomas for reassigning this to Ubuntu.
That would look like an issue with the KVM HW support, but is too long ago for anything reasonable to be done.

If this still is an issue please describe what you encounter and add current logs.
Marking incomplete for now.
