[libvirt] [PATCH v2] Memory : Allow specification of 'units' for numa nodes.



Reference :
=======
v1: http://www.spinics.net/linux/fedora/libvir/msg105516.html

Changes since v1:
===========
1) As suggested by Michal, a new function "virCPUNumaCellMemoryParseXML" has
been introduced for neat computation of NUMA memory.
2) Patches 2 & 3 of v1 have been merged together into this cumulative patch.
3) Corresponding documentation added.

>From 2199d97b88cf9eab29788fb0e440c4b0a0bb23ec Mon Sep 17 00:00:00 2001
From: Prerna Saxena <prerna linux vnet ibm com>

CPU numa topology implicitly allows memory specification in 'KiB'.

Enabling this to accept the 'unit' in which memory needs to be specified.
This now allows users to specify memory in units of choice, and
lists the same in 'KiB' -- just like other 'memory' elements in XML.

    <numa>
      <cell cpus='0-3' memory='1024' unit='MiB' />
      <cell cpus='4-7' memory='1024' unit='MiB' />
    </numa>

Also augment test cases to correctly model NUMA memory specification.
This adds the tag 'unit="KiB"' for memory attribute in NUMA cells.
