Just allow me to note that hypervisor's and tools' are different
interfaces, so they don't necessarily have to match.

So, yes, if you like my idea/proposal, then fine, but I just wanted to
point out as clearly as possible that I wasn't implying or asking that
it should be the same as Xen interface... Of course, it happens quite a
few time that the interfaces match, which is fine too, it just should
not be treated as a goal! :-)

Exactly, let's hear from them first.
