title: Libvirt Cannot Stop Reboot Force Shutdown or Destroy Guest
body: <p>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.</p>
  
  <p>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".</p>
  
  <p>I really cannot just delete these guests and start over.   How can I recover them?</p>
