if you end up in fault.c (via call to handle_page_fault) then I think you 
allready had an invalid access - you should not have ended there if the 
tlb entries would have been loaded properly from where ever XM put them
(not in any pgd that linux knows of) - no COW or lazy mechanism available
as the pgd of the domains are not handled in fault.c .
