I downloaded the version you mentioned, and put the copied disk back into 
the physical host, and installed the drivers. In the end it said, 
successfully installed. However, I saw such messages, when I took a look 
into the detailed installation log:

...
Installing the driver....
Updating the driver...
The device is not plugged in, cannot update the driver.
Installing the driver...
Completed

Then I put the disk back into the xen host, but I still get the BSOD.
When I boot in save mode, it shows a list of drivers that it loads, but 
there I cannot see anything regarding some xen drivers used, what I 
expected.
In one of the other tests I did, I downloaded the PV drivers from Novell, 
and installed them. With these I also still get the BSOD, but I saw at least 
the xenbus.sys file in the list of loaded drivers when booting windows in 
safe mode.

However, I also installed XP Pro from scratch in Xen, and then installed the 
GPL PV drivers there. After the installer was done, windows detected the new 
hardware and installed the drivers.

Will it work, when I take a look into the installed Xen domU, copy the 
driver *sys files, and corresponding *inf files to a CD, and then use the 
recovery console on the host where  I get the BSOD, to copy the files on the 
same place on that host?
Do I need to do more to get these drivers activated then?

kind regards
Sebastian
