Libvirt Cannot Stop Reboot Force Shutdown or Destroy Guest

virtual-machine kvm libvirt

The subject pretty much says it all. I am running libvirt (KVM?) on Ubuntu and I have two guests (both ubuntu server) that I cannot access or control.

That is, if I view them with virsh or virt-manager, their status is "running". I cannot connect to the graphical console. If I send the keys ctrl-alt-del nothing happens. If I try to "shut down" I get the error "error shutting down domain. Timed out during operation. cannot acquire state change lock".

I really cannot just delete these guests and start over. How can I recover them?

There could be qemu-kvm process(es) running for the guests. kill them manually (kill -9) and then start it from virt-manager/virsh.
