Title:
  nova-compute is started before libvirt

Status in nova package in Ubuntu:
  Triaged
Status in nova package in Fedora:
  New

Bug description:
  Ubuntu 14.04, nova 2014.1.2-0ubuntu1.1

  Rebooting nova-compute node results in a non-running nova-compute
  service. This is due the fact that nova-compute starts before libvirt:
