Hi,
I am using the latest ovs code base to try vhost user based on Ciara Loftus's
patch
("[PATCH v4] netdev-dpdk: add dpdk vhost-user ports" which is not in ovs
upstream yet).
things go smoothly during VM bootstrap, as I can see following logs:

2015-05-23T04:02:33Z|00001|dpdk(vhost_thread2)|INFO|vHost Device
'/usr/local/var/run/openvswitch/dpdkvhostuser0' (0) has been added
However I cannot see any packet was polled afterwards even I generated some
traffic inside the VM.
My host and VM are using 3.19.0-15-generic, and qemu 2.2.0 is used.
Could any one please share any hint?
Thanks,
Tim
