ubuntu 14.04 KVM specified NUMA nodeset

Hi!

my enviroment : ubuntu 14.04 , kernel verison 3.19.0-25-generic,

 I used " <numatune> <memory mode='strict' nodeset='0'/> </numatune>" tag in VM's xml file and disable automatic NUMA balancing.

On host, used command "sudo numastat -c qemu-system" to check VM memory, the output is:

Per-node process memory usage (in MBs)
PID............................. Node 0 Node 1 Total
--------------------------- ---------- ---------- ---------
24853 (qemu-syst..... 349 ........ 47 ...... 395
25214 (sudo).................1 ........... 3 ........ 4
--------------------------- ---------- ---------- ---------
Total ............................. 350 ....... 49 ...... 400

I think VM's memory allocate all memory on Node 0, but VM's memory of 47MB in Node 1 .

How can I allocate VM's all memory in specified NUMA ?
