Then forget about Xen (just my opinion) , i mean Xen without proprietary
drivers for the emulated nics, scsi controllers etc ... 
I've seen during my tests that it's faster to run a Windows (with the
freely available/included vmware guest drivers) box inside of Vmware
server than the same Windows (without any optimized drivers, because not
availble) in Xen ...
I know that such 'accelerated' drivers for Xen are available from
Xensource and were announced also by Novell (for a annual price of 300
$ / guest iirc ! , to be verified though).
Red Hat announced the same thing (no prices yet) for the xen optimized
drivers for unmodified OSes for 5.1 ...
