2.create vm1 without numa config, 64G memory
3.create vm2 with numa config(1 numa node 32G memory),finally the vm's memory is allocated on numa node0 of host
4.run memory test process in vm1，and let it's memory full(from numactl -H of host, i found vm1 used 40G memory on numa node0 of host)
5.run memory test process in vm1，try to let it's memory full
6.the vm1's qemu process is crashed by OOM
