Bug Description

We observed that DPDK-enabled application running inside an instance can cause segmentation fault in host OpenVSwitch. More information available here: http://dpdk.org/ml/archives/users/2016-June/000672.html

Workaround: This problem seems to be dependant on guest DPDK version, so it might be helpful to use latest release (v16.04 at the moment) or even master branch.
