Hmm. I suspect xen's direct paging mode makes that quite intrusive as
the kvm mmu code would have to know about this extra p2m translation
step to get the shadow/ept/ntp tables right. Given that this most
likely would be a odd and rarely tested use case I don't think this
would be a good idea ...
That's mostly encapsulated in the normal pagetable manipulation
routines, so if kvm can be convinced to use those to manage its shadow
tables, it will all Just Work. That doesn't work well with a non-PAE
32-bit host with kvm's PAE shadow pagetables, but Xen doesn't support
non-PAE anyway.
