What version of libvirt are you using, in case it is something that has
been improved in the meantime?
I tried this again today with a recent version pulled from git. The
following is the top commit.
commit b02fca79e858dc6e6d3209a44fe967f038ac6291
Date: Wed Jul 9 10:57:33 2014 +0200
I'll take another look at the code. Hopefully I can figure out why the
messages are getting lost.
Sorry for the delayed response.
