In this tutorial we will show detailed instructions and debugging info, in order to deploy a DPDK enabled OVS on an Openstack Newton environment, on Ubuntu 16.04.
First and foremost you must have a working Openstack Newton environment with OVS networking.
Secondly you need to have a DPDK enabled OVS, built and running on your system.
The easy way to do that is to just download and configure the official package.
Following these instructions:

Single Root I/O virtualization (SR-IOV) in networking is a very useful and strong feature for virtualized network deployements.
SRIOV is a specification that allows a PCI device, for example a NIC or a Graphic Card, to share access to its resources among various PCI hardware functions:
Physical Function (PF) (meaning the real physical device), from it a number of one or more Virtual Functions (VF) are generated.
Supposedly we have one NIC and we want to share its resources among various Virtual Machines, or in terms of NFV various VNFCs of a VNF.
We can split the PF into numerous VFs and distribute each one to a More >
