i haven't compared performance, as i still don't have any VT-capable hardware 
(and won't for several months more).  in fact, that's my biggest obstacle to 
using all Xen.  still, your performance numbers are too low, i don't think 
that's all you should get.

i guess it should;  the usage scenario for paravirtualized drivers (when and 
if they're implemented) is to first install windows on a fully virtualized 
hardware and after that installing an 'enhancement pack' with drivers for HD 
and network that can detect the Xen hypervisor underneath, and optimize for 
that.
