    <div>You get it. This is the bug I mentioned
      related to compute nodes. Folks, anyone knowing the bug tracking
      numbre, btw ?<br>
      <br>
      'ovs-dpctl show' shows you that only qvo7dcd14b3-70 is bridged to
      br-int (and mapped to vnet4, which I guess is the vnet device for
      the correct VM).<br>
      <br>
      Could you please try :<br>
      sudo ovs-vsctl add-port br-int qvo0b459c65-a0<br>
      sudo ovs-vsctl add-port br-int qvo4f36c3ea-5c<br>
      sudo ovs-vsctl add-port br-int qvo62721ee8-08<br>
      sudo ovs-vsctl add-port br-int qvocf833d2a-9e<br>
      sudo service quantum-plugin-openvswitch-agent restart<br>
      <br>
      and check that your VMs get network back ?<br>
