[Qemu-devel] [PATCH v18 00/14] Add support for binding guest numa nodes to host numa nodes

[Hu Tao <hutao@cn.fujitsu.com>]

The major change from v17 is the patchset is now based on memory backend.
Example command line:

./x86_64-softmmu/qemu-system-x86_64 -hda /path/to/image.img -smp 2 \
   -object memory-ram,size=512M,host-nodes=1,policy=membind,id=ram-node0 \
   -numa node,nodeid=0,cpus=0,memdev=ram-node0 \
   -object memory-ram,size=1024M,host-nodes=2-3,policy=interleave,id=ram-node1 \
   -numa node,nodeid=1,cpus=1,memdev=ram-node1 \
   -m 1536M

There are some minor problems but I'd like to see if there are any problems in the
general direction. Your comments are welcome!
