[libvirt] [PATCH 0/5 v3] Add NUMA memory tuning support

Hi, This series incorporated previous feedbacks received on the XML schema, especially on syntax of "nodeset". Now using same syntax of "cpuset" of "vcpu". And doing conversion in qemu driver internally, as libnuma uses different bitmask format to represent NUMA nodes. The XML is like: <numatune> <memory mode="strict" nodeset="0-10,^5"/> </numatune> Value of "mode" can be either of "strict", "preferred", or "interleave". One may specify nodemask which is out of range, for this case, libvirt will report soft warnings instead of hard error. (Kernel is silent as long as one of the set bit is valid, E.g. For a host with 2 NUMA nodes, kernel will be silent for nodemask "0101010101", as first "bit" which represents the first NUMA node is set). The reason for reporting soft warnings instead of hard error is one may want to define the memory tuning policy priorly with a node doesn't exist yet, but may come soon. Any feedback is appreciated.
