Performance isn't too bad even without this. At least if the host

Well, any workload that benefits from npt would benefit from nnpt a
lot more.
Most complicated part will be the two dimensional software page walker.
That will be a somewhat intrusive change (at least if I do it without

I think if you change the memory accessors to go through
kvm_read_guest_virt() again, you'll get it almost for free. You'll need
to supply a context so the accessors know which level you're accessing.
