ETSI releases v2 of thier Open Source MANO (Management and Orchestration) for VNF/NFV & it uses LXD

ETSI OSM release 2

To install OSM Release TWO from source, requirements are the following:

8 CPUs, 16 GB RAM, 100GB disk and a single interface with Internet access Ubuntu16.04 as base image, configured to run LXD containers.

Note: If you wish to install OSM Release TWO from inside a LXD container, you will need to enable nested LXD containers (instructions are on the ETSI OSM website)

So what is a VNF (also often called a NFV)…

A virtualized router is called a Router VNF.

So if you virtualized Quagga, BIRD or the new Free Range Routing (FRR) to do BGP, OSPF etc you would have a Router VNF.

Other VNF examples include applications like - firewalls, IPS, GGSN, SGSN, RNC, EPC etc
