Comment 0 for bug 1657354

Deployment of openstack having one controller and one compute node with OVS-DPDK and NSH is successful. However OVS does not start with DPDK options and error in ovs-vswitchd.log - "could not create netdev dpdk0 of unknown type dpdk"

The DPDK options are enabled in /etc/default/openvswitch-switch.

root@node-17:~# cat /etc/default/openvswitch-switch
/etc/init.d/dpdk start

export DPDK_OPTS="--dpdk -c 0x1 -n 2 --socket-mem 2048"

Tried to manually add the DPDK_OPTS in /usr/share/openvswitch/scripts/ovs-ctl by following - https://bugs.launchpad.net/ubuntu/+source/openvswitch-dpdk/+bug/154746
when service openvswitch-switch restarted, there was error - ovs-vswitchd: DPDK support not built into this copy of Open vSwitch.
