Dear Michal:
I'm sorry. The pasting XML I described earlier is wrong, and the real thing is:
    <interface type='bridge'>
      <mac address='52:54:00:0a:2b:2a'/>
      <source bridge='lcs_br_1'/>
      <virtualport type='openvswitch'/>
      <bandwidth>
        <inbound average='0' peak='0'/>
        <outbound average='0' peak='0'/>
      </bandwidth>
      <model type='virtio'/>
    </interface>

I'm really sorry. I forgot I had QoS defined on the virtual machine.
And this problem doesn't happen every time. I encountered this problem when I used the same XML to create about 100 virtual machines on a hypervisor.
