That looks promising! Its a bit more complex (or at least 'new' for me)
than that I was hoping. There is Gluster support in there, I found a
description of it here:
  http://avocado-vt.readthedocs.io/en/latest/GlusterFs.html
  http://avocado-vt.readthedocs.io/en/latest/RunQemuUnittests.html

Browsing through the docs does not really explain me how to put a
configuration file together that runs the QEMU tests with a VM image on
Gluster though. I probably need to read much more, but a pointer or very
minimal example would be much appreciated.

When I'm able to run avocado-vt, it should be trivial to put that in a
Jenkins job :)

Many thanks,
Niels
