Another question: in my windows DomU the old realtek RTL8139 emulated
network card driver still shows, and the Intel 82371SB Bus master IDE
controller. 
They all have a "Device can not start" error. I have uninstalled them in
Device manager, but when I reboot they show up again, and event viewer
also has a few entries on the network cards not wanting to come up.

on the wiki ( http://wiki.xensource.com/xenwiki/XenWindowsGplPv ) they
want you to remove the vif entry. But I need two virtual networks to the
DomU.

I have removed the ioemu part, but no difference.
