Open Platform for NFV (OPNFV) (http://docs.opnfv.org/en/stable-danube/index.html) is an open platform from the Linux Foundation to facilitate Network Functions Virtualization (NFV) across various projects. Various network functions are virtualized and deployed as Virtual Network Functions (VNFs), with the support of NFV platforms such as OPNFV. OPNFV consists of many projects and features for Network Function Virtualization Infrastructure (NFVI).

OPNFV can be installed using various installation tools: Compass, Fuel, TripleO from Apex, and Juju. More details on the installation alternatives can be found at https://www.opnfv.org/software/downloads/release-archives/danube-2-0. In this recipe, we will look in to installing OPNFV with Compass in detail. As a large-scale cross-layer project with many components, OPNFV is developed in multiple languages. Python is used in OPNFV for many scripts including configuration and installation actions. As we will learn from this recipe, installing and troubleshooting OPNFV requires a Python development environment and extensive experience in Python.
