Re: [Xen-devel] Page access during migration

[Anthony Nocentino <nocentino@xxxxxxxxx>]

Mike,   
	Thanks for the reply, staring at the hypercalls in xen.h I didn't see  
anything that jumped right out at me. What I would like to do is take  
a peek at the flags in the page descriptor.
Are you referring to something like mapping foreign frames as  
mentioned in /xen-3.3.0/docs/misc/grant-tables.txt?
Thanks,
        anthony
