[Xen-devel] Mapping HVM memory to dom0 address space

[Marek Marczykowski <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

Is it possible to map domU pages based on PFNs in that domain? Or is it
possible to get MFNs from inside of HVM?
For PV guests I can MFNs from inside of guest, then pass it to
xc_map_foreign_pages in dom0, how achieve the same for HVM?
I have PV drivers inside of that domain if that helps.

It isn't possible directly, how is most efficient way to translate a bunch of
PFNs to MFNs for a given domain? xc_get_pfn_list, or there is something better?
