Not even a little bit of variation from that?

I could live with that, but I have heard mutterings that some people are
finding it hard to review the patches without knowing the interface the
are supposed to be implementing, which is pretty fair I think.

Could you perhaps enumerate the exact set of XENFEAT flags which
must/must not be used/supported by a PVH guest in a document somewhere?
That would hopefully explain the vast majority of the differences
between trad-PV and PVH and be pretty succinct I think. Anything which
isn't explained away by a particular feature flag might need additional
explanation.

Ian.
