libvirt/virsh unable to destroy vm

Question

I have a big problem with my kvm:
I wanted to shut down my machine "Owncloud", after the power state of "Owncloud" is "in shutdown".
When I try to destroy this machine with "virsh destroy Owncloud" I got the following:

error: Failed to destroy domain Owncloud!
error: An error occured, but the cause is unknown

I'm using Ubuntu 13.04 for virtualization.

What can I do to destroy the machine without restarting the host system?

Answer 1

you can always kill qemu process directly, but libvirt log should provide better information on what exactly went wrong.
