Re: [libvirt] [PATCH 1/4] libxl: implement NUMA capabilities reporting
...bxl_get_physinfo() is xc_physinfo(), which is XEN_SYSCTL_physinfo,
which uses total_pages, which is assigned the number of pages, down in
__start_xen(), as it results from parsing the E820 map (looking for RAM
blocks).
OTOH, memsize comes from libxl_get_numainfo(), which is xc_numainfo(),
which is XEN_SYSCTL_numainfo, which puts in memsize what
node_spanned_pages(<node_id>) says.
That seems to come, on a NUMA box, from the parsing of SRAT, and on a
non-NUMA box, from just (start_pfn-end_pfn) (in pages, of course).
Anyway, on my NUMA box, I see something similar to what Jim sees on a
non-NUMA one:

[PATCH 00 of 10 v3] Automatic NUMA placement for xl
Hello,
Third version of the NUMA placement series Xen 4.2.
All the comments received during v2''s review have been addressed (more details
in single changelogs).
The most notable changes are the following:
- the libxl_cpumap --> libxl_bitmap renaming has been rebased on top of the
recent patches that allows us to allocate bitmaps of different sizes;
- the heuristics for deciding
