This guide is more of a tutorial that should guide you through all of the steps of installing DPDK and Open vSwitch from the packages built by the Debian Linux. This guide assumes the use of Intel Niantic NIC cards. Mellanox ConnectX3-Pro cards will be supported but are right now largely untested with the packages. This guide builds on the basic one and hopefully provides all of the steps you'll need to setup a working OVS-DPDK with a running VM (also with its own DPDK).
