Re: [Xen-users] xm dump-core and an XP HVM

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.

Best Regards,

Akio Takebe
