Re: [Xen-users] xm dump-core and an XP HVM 
| Akio, 
 Thanks for the reply.  How would I obtain max_pfn?  In xc_domain_dumpcore_via
 _callback, the code pulls nr_pages from the xc_dominfo struct and uses this value as the number of pfns for the domain.  Would max_pfn = nr_pages, or would they be different for some reason?  I'm planning on adding a dump-physical tool, and I'll post the code to xen-devel once I get it working.

Hi, Ryan
 Will you try to make a convert tools (from raw memory dump to
 Windows fomat dump)? If so, please post it to xen-devel ML.
 
 You can see docs/misc/dump-core-format.txt.
 ".xen_pages" section is raw memory,
 and .xen_p2m or .xen_pfn sections are used
 for looking for a memory address we want to see.
 
 You can see them with readelf -x option.
 
 If you want to make a new tools to get a straight dump of physical memory,
 it would just do xc_map_foreign_range() from 0 to max_pfn.
