This isn't uncommon.  Most BIOSes disable virtualization at boot time by 
writing to a processor-specific register (which, on Intel, cannot be 
unset without booting).  This is a security feature to stop a particular 
form of near undetectable rootkit.  So you need BIOS support and this is 
commonly supplied through BIOS upgrades - eg. Lenovo did this for the 
Thinkpad models which support HVM.

Xen upstream certainly support Windows under Xen.  Of course you 
absolutely do need hardware virt support in your processor.  It may not 
surprise you to know that we don't use very much Windows round here, so 
I can't personally comment on how well it works.
