Currently none.  Xen Enterprise has PV drivers for windows, but you have 
to purchase that from Citrix to use that.
There is a work in progress to develop GPLed PV drivers for windows by 
the community, but  I don't know its current status.  Till the time 
those drivers are available, the performance may not that much 
impressive, but I think it should be ok while comparing with VMware 
since VMware is another beast in crumbling performance.
