While thinking about the HVM part: should I only create an opt_feature
#define OPTF_IDENT_MAP_HVM_REG4_5
and simply replace the
if (GOS_WINDOWS(v)
by
if (opt_feature & OPTF_IDENT_MAP_HVM_REG4_5)
or should I do it the same way like on PV with setting pgprot and key
(maybe this is overkill?) in the struct arch_domain and use these values
during the optimization?
Thanks.

Dietmar.
