Just FYI, there's a "NUMA angle" of the whole balloon driver improvement
process, the bulk of which is how to make the balloon driver (v-)NUMA
aware.

Some (quite interesting, actually) discussion on that happened already,
and can be found on this message, and in the subthread it generated:

  http://lists.xen.org/archives/html/xen-devel/2013-08/msg01691.html

It's probably something almost completely orthogonal to what's discussed
here, and, more important, vNUMA topology support in the guest is a
pre-requisite for that but, especially considering you've been involved
in vNUMA too, I thought I would at least mention it. :-)

Regards,
Dario
