Open Source MANO (OSM)

A full deployment consists of 3 components:

• OSM as the NFV Orchestrator
• OpenVIM or Openstack as the virtual infrastructure manager (VIM)
• some number of compute nodes, where the VIM will run VMs under OSM's instruction

We will use the following components:

• OSM on ubuntu 18.04
• Devstack on ubuntu 18.04, in a single node configuration (this can easily be extended following devstack guides)

OSM Node

This tutorial implements the getting started from: ​https://osm.etsi.org/wikipub/index.php/OSM_Release_SIX

and adds support for ORBIT hardware.

The previous tutorial targeted Ubuntu 14.04 and 16.04, this is updated for Ubuntu 18.04.

Pre-set-up:

omf load -t srv1-lg1.sb1.cosmos-lab.org -i opensourcemano_1804.ndz

ssh Credentials: native / native

Web Credentials admin / admin

From Scratch

Dependencies:

• 40Gb disk space
• user:
  • non-root user,
  • with non-empty password
  • member of sudo, docker, lxd groups
• Packages:
  • net-tools
• ipv6 disabled

1. Prepare the node
   1. Load the image: omf load -t srv3-lg1.sb1.cosmos-lab.org -i baseline_1804.ndz -r 60
   2. Turn the node on: omf tell -a on -t srv3-lg1.sb1.cosmos-lab.org
   3. Log in as root: ssh native@srv3-lg1.sb1.cosmos-lab.org
   4. set up non-root user echo native:native | chpasswd
   5. Add user to groups: sudo groupadd lxd && sudo groupadd docker && sudo usermod -a -G lxd,docker native
   6. logout: exit
   7. Log in as the user "native": ssh native@srv3-lg1.sb1.cosmos-lab.org
2. Set up OSM
   1. Install "net-tools" sudo apt install net-tools
   2. Download script: wget https://osm-download.etsi.org/ftp/osm-6.0-six/install_osm.sh
   3. Make it executable: chmod +x install_osm.sh
   4. Run it: ./install_osm.sh 2>&1 | tee osm_install_log.txt
   5. enter "y"
      1. if it crashes, run lxd init
   6. choose all defaults, except none for ipv6
   7. if failed, rerun install_osm.sh
3. Connect browser
   1. Via ssh tunnel
   2. via VPN TODO
   3. navigate browser to node control ip, enter admin/admin as credentials

VIM Node

OSM must have a Virtual Infrastructure Manager (VIM) to control. We will use openstack on single node devstack for this tutorial, following: ​https://docs.openstack.org/devstack/latest/guides/single-machine.html

Pre-Set up:

omf load -t srv2-lg1.sb1.cosmos-lab.org -i devstack_1804.ndz

• edit local.conf with the ip of the correct node
• create desired networks
• run stack.sh

From Scratch

Follow ​https://docs.openstack.org/devstack/latest/guides/single-machine.html

Connecting OSM to the VIM

• URL http://openstackip/identity/v3
• User admin
• password nomoresecret
• tenant admin
• name openstack-site

Creating a VNF

• upload vnf description
• upload nf descrtiption

• instantiate nf

• use openstack ui to load console and ping
