  For my windows xp domU, I have been used 0.9.12.pre13 version for a long
time without any major problem. 
  Since I have known there be some performance improvement in 0.10.x
verison for windows xp with PATCHTPR, then I uninstall 0.9.12 version,
and reinstall 0.10.86 version, first I got a bluescreen, after enable
/nogplpv and disable it, then it work.
  But I found my rdesktop session to my windows xp domU will "hang"
for some time, for example, if I watch a flash via a rdesktop session,
If I don't move mouse, then the play will stall at some time, if I keep
moving my mouse, it will play ok.
  tcpdump on vif interface show there is no packet sent from the domU 
at the stall time. It seems some packets get lost at the driver layer?
  After revert back to the old 0.9.12.pre13 version, this problem
  And more, when using 0.10.86 version, login in to a windows xp domU is
slower then the 0.9.12.pre13 version, you can feel the refresh of the
desktop. I suppose it is the same problem.
  I have tried  0.10.69 version too, the problem exist too.
  So I guess it is a problem in 0.10.x version?
