my main goal is to add support migration with host NIC passthrough devices and keep the network connectivity.
this series patch base on Shradha's patches on https://www.redhat.com/archives/libvir-list/2012-November/msg01324.html which is add migration support for host passthrough devices. 1) unplug the ephemeral devices before migration 2) do native migration 3) when migration finished, hotplug the ephemeral devices TODO: keep network connectivity on guest level by bonding device.
