Split network plane for live migration

Registered by Rui Chen on 2015-06-23

Now data transfer of live migration occupy the management network of openstack deployment. In the KVM/QEMU driver, we use hostname of target compute node in CONF.libvirt.live_migration_uri, so rpc call and data transfer of live migration will be in same network plane, live migration will impact the network performance, the impact is obvious when lots of live migration occur at the same time, even if CONF.libvirt.live_migration_bandwidth been set.

This blueprint purposed to split network plane of live migration, the operators can plan a specify network plane for live migration and split it from management network.
