Does the hvmstub have to look different to an hvm guest from the p.o.v. of
the tools? It's rather a shame to introduce a third kind of domain at that
level.

How do you think this appraoch compares with a separate stub domain per HVM
guest? That's the approach being developed on the x86 side, but it would be
nice to not increase divergence between x86 and ia64.
