Thread-topic: basic mfn question
This should be an easy one.  :^)
When two domains share a memory page via grant tables (or any other
method for that matter), should the mfn of the page be the same in both
domains?

I think the answer is yes, in which case I have a bug such that:
pfn_to_mfn( page_to_pfn( page )) gives a different value in each domain.
