[Xen-devel] MFN & Page Mapping

["Kumar, Venkat" <Venkat.Kumar@xxxxxxx>]

When I share a page between a HVM domain (who offers the page) and a PV domain (who maps the page), I realized that the MFN (machine frame number) of the shared page in both these domains are different.

When I do virt_to_mfn on both the domains I get a different machine frame number. Is it expected or is the page really getting shared? I could see the contents of the page identical from both the domains.

 

Any clues?

 

Thx,

Venkat
