Yes - it's possible. Yes - I've successfully had Windows XP, Windows
2003 Server, and recently Windows 2000 installed via a XEN kernel on
SLES 10 (including all updates).

Yes - I've done this. Only on a disk image file as it was purely for
testing and demo purposes. I found it was easier to build the image via
Qemu first and then use this image via XEN. I have however, built images
entirely through XEN - albeit some months ago and had a few install
stability issues (seem to be much improved in the latest SLES 10
releases and by reducing the Dom0 memory)

You can *only* install Windows in a XEN environment if you have the
correct hardware from AMD or Intel. There are plenty of posts here that
state you need an Intel VT chip or an AMD 'Pacifica' (I can't remember
the released branding for the chip... Pacifica is a much cooler name :-)
). You can verify that you have this type of chip by looking at
/proc/cpuinfo (AMDs have the svn flag - I can't remember what Intel's
have... google is your friend here).
As you can probably guess, my install system was an AMD system, with 4GB
of RAM. I've used both 32 bit and 64 bit kernels for XEN and been able
to run 32 bit Windows. I've not yet been able to install 64 bit Windows
- keeps barfing on the ACPI stuff (although I've not had a go again for
a while lately).
Hopefully some of this helps clarify that it is indeed possible on the
correct hardware.
