Comment # 7 on bug 1017394 from Lin Ma

Please modify vcpu model in guest xml to this:
  <cpu mode='custom' match='exact'>
    <model fallback='allow'>kvm64</model>
  </cpu>

Then observe what happens.



If the issue is reproduced, then please modify guest xml to change vcpus
topology to this:
  <cpu mode='host-model'>
    <model fallback='allow'/>
    <topology sockets='1' cores='2' threads='1'/>
  </cpu>

observe what happens.
