We would like to avoid going through VDSM completely, except from the
broker part. Is it possible now to "parasitically" listen to vdsm
events and engine commands without having to go through VDSM API?

You can drop XML RPC,. vdsm does not depend on MOM working anymore.
Just the balloon and ksm stats will be missing from data that are
being sent to the engine.


There also were some issues with eventfd in the json library, I assume
those are fixed now.
