While trying to numa/vcpu pin the instance to the nova computes pcpu on Redhat 7.1 with Openstack Kilo getting "Per-node memory binding is not supported with this QEMU"

Issue

• We want to enable NUMA/vCPU pinning on Openstack kilo under RHEL7 for host OS, but when I added one flavor spec like as hw:cpu_policy: dedicated into our flavors and to create one instance using this flavor with extra spec, we encounter an issue:

libvirtError: unsupported configuration: Per-node memory binding is not supported with this QEMU.

• Instance is being defined with the following XML:

  <vcpu placement='static'>2</vcpu>
  <cputune>
    <shares>2048</shares>
    <vcpupin vcpu='0' cpuset='5'/>
    <vcpupin vcpu='1' cpuset='21'/>
    <emulatorpin cpuset='5,21'/>
  </cputune>
  <numatune>
    <memory mode='strict' nodeset='0'/>
    <memnode cellid='0' mode='strict' nodeset='0'/>
  </numatune>

• We followed the CPU pinning documentation
