It shouldn't be all that hard to avoid doing a full-fledged
conversion.  I've in the pat managed to configure KVM so that a
particular installation of Windows could be run either natively or
under KVM.  The hard part would be to make Windows not notice the
change in device drivers necessary, so trying to make this work with
paravirtualization would be tricky.  But if you aren't shooting for a
full performance, it shouldn't be that hard.

That being said, if someone were being employed by the NSA to attack
Iran, or by the MSS to attack the US Federal Government, or simply by
a russian firm wanting to make $$$ selling Viagra, they'd probably try
to shoot for figuring out some way to surrepticiously install the
paravirtualization drivers into an existing Windows install.  But this
is not a fundamental theoretical difficulty; just a practical one.)
