Como verificar se a 'ligação de memória por nó' é suportada em qualquer versão do libvirt?

Question

Estou usando o kvm e obtendo um erro: configuração não suportada: A ligação de memória por nó não é suportada com este QEMU

Eu tenho a versão #virsh:

Compiled against library: libvirt 1.2.9
Using library: libvirt 1.2.9
Using API: QEMU 1.2.9
Running hypervisor: QEMU 2.0.0

no host  # uname -a

Linux nfv 3.13.0-40-generic #69-Ubuntu SMP Thu Nov 13 17:53:56 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

# lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.1 LTS
Release:        14.04
Codename:       trusty

Quando tento iniciar a instância, ele falha com erro (#virsh start SomeOSOS-30-5-0-0_rls_743):

   error: Failed to start domain AlteonOS-30-5-0-0_rls_743
   error: unsupported configuration: Per-node memory binding is not supported with this QEMU

Estou tentando encontrar qualquer abilidade para verificar se o libvirt + QEMU está suportando essa opção.

É xml:  #virsh dumpxml SomeOSOS-30-5-0-0_rls_743
