I agree with you, especially as this already works for Xen.
Note it doesn't completely solve the issue (so we have two interfaces,
which is the preferred one?), but it's better than nothing.
Windows doesn't look beyond 0x40000000, so Hyper-V stays there and KVM
has to shift. So MS solved that part for us. :)
