  apt-get install nova-compute has odd configuration order

  Done.

  
  nova-compute-kvm -> nova-compute-libvirt -> nova-compute -> nova-compute-kvm | nova-compute-hypervisor

  this is a little circular - installing 'nova-compute-kvm' dtrt and
  ensures nova-compute-libvirt is configured before nova-compute-kvm,
  resulting in the correct group membership of nova->libvirt, but
  install of 'nova-compute' results in the group membership being setup
  after the nova-compute daemon starts.

  Result is that on first exec, nova-compute can't access the libvirt
  socket, but the systemd unit restarts the daemon a few times until the
  permission is correct.
