[Xen-devel] Pages allocated for a process in a Domain
Hi,
I am currently working on a security based research project, wherein I wish to do complete memory introspection of a process running on a VM. With regards to this, I need the addresses of the memory pages allocated by xen for that particular process.
I did go through XenAccess and some related structures like pt_base, mfn_list, xen_machphys_mfn_list and xen_machphys_mapping, but none of them seem to be working on process level granularity (correct me if I am wrong).
I have currently implemented a custom hypercall in xen. I am invoking this hypercall from a userspace program in DOM U. The program that invokes the hypercall needs be memory instrospected and so I want to figure out the memory addresses of pages allocated
for this particular program. Any pointer on this would highly appreciated.
I hope this detailed explaination would fetch me some valuable suggestions.
Thanks
Regards,
Satyajeet

Hi,
Can any one please guide me as to how should I find out the exact addresses of the pages allocated for a particular process running on DOM O.
I learned about some related structures like pt_base, mfn_list, xen_machphys_mfn_list and xen_machphys_mapping. But I still have little clue as to how should I use them to achieve what I want.
Thanks.
Regards,
Satyajeet
