  Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
  Your project "openstack/nova" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

      Split-network-plane-for-live-migration
      
      When we do live migration with QEMU/KVM driver,
      we use hostname of target compute node as the
      target of live migration. So the RPC call and live
      migration traffic will be in same network plane.
      
      This patch adds a new option live_migration_inbound_addr
      in configuration file, set None as default value.
      When pre_live_migration() executes on destination host, set
      the option into pre_migration_data, if it's not None.
      When driver.live_migration() executes on source host,
      if this option is present in pre_migration_data, the ip/hostname
      address is used instead of CONF.libvirt.live_migration_uri
      as the uri for live migration, if it's None, then the
      mechanism remains as it is now.
      
      This patch (BP) focuses only on the QEMU/KVM driver,
      the implementations for other drivers should be done
      in a separate blueprint.
      
      DocImpact:new config option "live_migration_inbound_addr" will be added.
