To summarise this discussion so far.

Conceptually speaking, the guest should not need to know the mapping.
The translation from vnode to pnode should happen in hypervisor without
guest knowing.

Jan, Dario and David (and I) are all in favor of *not* exposing the
mapping (though starting from different angle). So we should go with
this approach. The hypercall interface is fine as it is now.

Wei.
