There are many other configuration options, the most important of which are listed below. Defaults will be provided for all values not explicitly set. dpdk-init Specifies whether OVS should initialize and support DPDK ports. This field can either be true or try.A value of true will cause the ovs-vswitchd process to abort on initialization failure.

Using Open vSwitch with DPDK Open vSwitch can use Intel(R) DPDK lib to operate entirely in userspace. This file explains how to install and use Open vSwitch in such a mode. The DPDK support of Open vSwitch is considered experimental. It has not been and .

OpenVswitch-DPDK being an exception to that (see below), but in general it is very likely that you might want / have to compile an app against the library. You will often find guides that tell you to fetch the DPDK sources, build them to your needs and eventually

Follow the steps in this tutorial to set up OvS-DPDK on Ubuntu* Server 17.04 for a DPDK vhost-user inter-VM application use case. Use iPerf3* to validate your configuration.
