just for the record, xen is a virtual machine monitor,
not an emulator, and strictly speaking, neither is QEMU
(which is a hybrid of binary translator and harware
 simulator)

but of course, it will also kill the good performance
xen could have with a windows support (which already
worked, but is very unlikely to work in the future, as
it requires M$ to adapt their OS to the xen architecture)
