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

2014-06-25 Thread 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'
 nameram0/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

I'm afraid, it seems you've duplicated work that's already in progress:
