Hi All,

I am trying to have a configuration with dpdk-ovs in both host/guest. But
when I try to add the guest interface as dpdk port to ovs in the guest,
vswitchd process crashes both in the host/guest with the traceback as
below.

Please let me know if dpdk-ovs in both host/guest is a tested configuration
and is expected to work. If somebody is able to have this running, plz help
me.

(Note: I have being able to successfully bringup dpdk-ovs in the guest
running on normal host without dpdk ovs. I have multi-queue enabled).
