just for the record in case somebody else faced this issue. I discussed that with Sergey and the conclusion looks as follows: """ I've discovered that the actual behavior, it's described here: http://dpdk.org/ml/archives/dev/2016-July/043104.html. So I just updated packages and it works fine for me. Now I am running dpdk 16.07 with ovs 2.5, qemu 2.5 and lbvirt 1.3.1. Seems problem is gone. """ Br, Robert
