Comment 6 for bug 1540537

These are the steps that I followed for verification:

1) I created 2 virtual machines

$ uvt-kvm create trusty
$ uvt-kvm create trusty2

2) On the primary (trusty) I created a machine called test

$ uvt-kvm create test

3) Installed openvswitch

$ sudo apt-get install openvswitch-switch

4) Created a new openvswitch bridge

$ sudo brctl addbr br0
$ sudo ovs-vsctl add-br br0
$ sudo ifconfig br0 up

5) Edited the network

$ virsh destroy test
$ virsh edit test

    <interface type='bridge'>
      <mac address='52:54:00:66:99:7b'/>
      <source bridge='br0'/>
      <virtualport type='openvswitch'>
        <parameters interfaceid='74178f6a-14bc-45d0-a54c-11aa8b907622'/>
      </virtualport>
      <model type='rtl8139'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </interface>

6) Start the domain

$ virsh start test

7) Migrate between both systems:

$ virsh migrate --live --p2p --persistent --abort-on-error trusty qemu+ssh://ubuntu@192.168.122.110/system

At this point the migration completes correctly, without the virCommandWait:2423 exception.
