Hi Emilio,
Thanks for sending this!  Could you and Lluís collaborate on a single
instrumentation plugin API?

Let's have a discussion with Lluís, Peter, myself, and potentially
others then we can use the QEMU Developer Conference Call that is
scheduled every 2 weeks.

The next call time slot is Tue 26 Sept at 13:00 UTC:
