Mh. My feeling is that the domU does not get enougth CPU to
process/forward.
This feeling is due to the fact that sending data from the domU to the
dom0 is very fast.
The opposite direction is slower.

I played with the sched-credit. Raising and lowering the dom0 weigth by
a factor of 2 does not
change the behavior.

Good idea. Will do that. Thank you very much.
