hi, We are currently trying to deploy ovs-dpdk in kolla-ansible pike branch. We have made changes in globals.yml as:

ovs_datapath: "netdev"
enable_ovs_dpdk: yes
enable_openvswitch: yes
tunnel_interface: "dpdk_bridge"
neutron_bridge_name: "dpdk_bridge"

After deployment is over we see that neutron-openvswitch-agent docker container is in restarting mode.

logs for neutron-openvswitch-agent container: http://paste.openstack.org/show/669729/

error logs dor ovsdpdk-db shows:

2018-02-12T11:22:38.147Z|00067|dpdk|ERR|MBUF: error setting mempool handler
