FreeBSD on Xen with hw virtualization support

Yes it works but with lower performance level.
The image i've linked to the list have both kernel (a basic kernel like for real HW
and a Xen PV kernel). By switching some token in the Xen config file 
you can switch from one to the other.

There is a third mode which i havent personnnaly tested (HVM) that will
normally be between the two in term of performance level.

Fabien
