    libvirt: slow live-migration to ensure network is ready

    In Neutron, commit b7c303ee0a16a05c1fdb476dc7f4c7ca623a3f58 introduced
    events sent during a live migration when the VIFs are plugged on
    destination node.

    The Linux bridge agent mechanism driver is detecting new networks on
    the destination host only when the TAP devices are created, and these
    tap devices are only created when libvirt starts the migration. As a
    result, we must actually start the migration and then slow it as we
    wait for the neutron events.

    This change ensures we wait for these events.
