Nice!

I have also been experimenting. I have some Python code in
https://github.com/dhellmann/metering-prototype that listens for
notifications related to instances (create, delete, exists) and converts
them to counter output (see spy.py). There is also a pair of scripts for
recording an event stream and playing it back (useful for testing, see
recorder.py and player.py). I don't have any libvirt polling, yet, though.

In the course of looking at the notifications being generated for different
scenarios, I discovered that the instance delete messages do not have any
duration information right now. I don't know if that is a bug, or if the
idea is to figure out the durations from looking at the most recent
"exists" event. What do other people think?
