Title:
  Resize/migrate stopped instance fails with Neutron event timeout

Status in OpenStack Compute (Nova):
  Fix Committed
Status in OpenStack Compute (nova) icehouse series:
  Fix Released

Bug description:
  I originally thought this was bug 1306342 but that's a different
  issue, that was when not having neutron configured properly for
  calling back to nova and nova would timeout on spawn waiting for a
  notification from neutron that networking was setup.

  This is a different issue where resize/migrate fails if you started
  from a stopped instance and using neutron.  In this case, the
  _create_domain_and_network method in the libvirt driver passes in
  power_on=False since the instance was stopped before the
  resize/migration.  The virtual interface isn't plugged in that case so
  we're waiting on a neutron event that's not going to happen, and we
  hit the eventlet timeout which then tries to destroy the non-running
  domain, and that fails with a libvirtError telling you that the domain
  isn't running in the first place.

  The fix is to check the power_on flag in _create_domain_and_network
  and if it's False, don't wait for neutron events, same as if
  vifs_already_plugged=False is passed in.
