  Okay, I think that patch set is ripe, and since it it not touching the
main libvirt API I think it's okay to push it now even if we entered
freeze yesterday.
  My main concern is error handling, we must improve that part in
subsequent patches preferably before the 0.10.0 release, an attempt to
run an unsupported agent command or with an error syntax should
be reported correctly at the C level and an exception should be raised
in Python.
  I also had to reformat all the comment which got mangled as the
mail title for some reason,

   Anyway it's in! thanks a lot, but let's fix the error handling :-)
