I understood that the virtual hardware used by Qemu and used by Xen's HVM 
(fully virtualised guests) has diverged somewhat so that it's not always 
possible to transfer guests between the too...  maybe that situation has / 
will improve.

Xen is reasonably good at running Windows in a domU but it's not good for 
running virtual machines "under Windows" in a vmware player / qemu style.

Windows as dom0...  it can't be done at the moment.  Maybe one day, if MS 
decide to make Windows interoperate much better with other company's 
hypervisors.  But I wouldn't count on it; they may want to restrict 
Windows "dom0-like" functionality to their own hypervisor.  I've heard noises 
suggesting that they will support running as a paravirt guest on Xen better 
in the future (and support will be available for running Xen guests on 
Viridian).

Cheers,
Mark
