[libvirt] [PATCH 00/10] -numa option parsing fixes & improvements



This series contains the following:

 * Patches 1-7 are multiple bug fixes to the current code
 * Patch 8 introduce a feature that libvirt requires since a long time,
   and even tries to use it today (in a way that doesn't work,
   using the "-numa node,cpus=1,2,3,4" format): having non-contiguous CPU
   ranges assigned to a NUMA node.

The last 2 patches I am sending as RFCs:

 * Patch 9 makes the "-numa" option deprecated and introduces a "-numa-node"
   command-line and config file option.
 * Patch 10 adds a small hack to the (now deprecated) "-numa" option, that
   makes the "cpus=1,2,3,4" format currently used by libvirt work.

  vl.c: Handle legacy "-numa node,cpus=A,B,C,D" format
