[libvirt] [PATCH 0/3] add binding guest numa nodes to host numa nodes support

[Chen Fan]

Since qemu has supported numa option -memdev config:
   -object memory-backend-ram,size=1024M,policy=membind,host-nodes=0,id=ram-node0 \
   -numa node,nodeid=0,cpus=0,memdev=ram-node0 \
for binding guest numa nodes to host numa nodes.

 So we introduce this capability in libvirt by configuration
 domain XML like:
  ...
  <cpu>
    <numa>
      <cell cpus='0-1' memdev='ram0'/>
    </numa>
  </cpu>
  ...

 <devices>
   <memdev type='ram' merge='yes' dump='yes' prealloc='yes'>
     <name>ram0</name>
     <capacity unit='MiB'>1000</capacity>
     <source host-nodes='0-1' policy='bind' />
   </memdev>
 </devices>

Chen Fan (3):
  numa: add '-numa memdev=' support
  conf: add memdev device in <devices> XML
  tests: add numa -memdev testing and docs support
