This is not as easy as you'd like it to be. KVM presents the guest OS
with an entirely different chipset and IO devices from the physical
system. It's effectively the same as yanking out your hard drive and
installing it into an old pentium-pro class system and expecting Windows
to "just work". Some have done it, with much registery hacking, but
it's not easy and appears fragile.

I thought that to be one of Window's strengths - to
"just work" in many hardware environments. Can you point me to any
information or discussion resources where I could find discussion and
more details on how others have done this?
Thanks,
