After fiddling with the bridge interfaces etc, I ended up
with a not-working-at-all system (not sure why, reboot
or something else).
But it also ended up as something weird.

So previously, they where all running on the Control node.
But this time, qrouter ended up on the Control node.
This actually got me thinking - should there BE a L3/Open vSwitch
agent running on the Compute node at all?? Isn't this the job of
the Control node!?
