Plus - is this in line with what the tools are doing? Aren't they
assuming !PV <=> native format context? I.e. don't you need
to treat differently v->domain == current->domain and its
opposite? Roger btw. raised a similar question on IRC earlier
Not sure I understand this. You mean for copying 64-bit guest's info
into 32-bit dom0?
Basically yes - tool stack and guest invocations may need to
behave differently.

This being PVH-"classic" it follows exactly the PV path (both in tools and the hypervisor). Wouldn't PV be broken then as well?
