>> Vhost Multi-Queue Support:  The vhost-user library will be updated to provide multi-queue support in the host similar to the RSS model so that guest driver may allocate multiple rx/tx queues which then may be used to load balance between cores. See http://dpdk.org/ml/archives/dev/2015-August/022758.html for more details.
