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)

This tutorial implements the getting started from: ​here, and adds support for ORBIT hardware, with the image based on Ubuntu 18.04.

To save time, run the OSM and VIM steps in separate ssh terminals, as they can be done at the same time.

OSM Node

Pre-set-up:
  1. Create a reservation
  2. Log into the console
  3. Load image: omf load -t srv1-lg1.sb1.cosmos-lab.org -i tutorial-osm.ndz -r 60
    1. You should see: INFO exp: 1 node successfully imaged ...
  4. Turn the node on: omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org
  5. Wait for the node to come up

VIM Node

OSM must have a Virtual Infrastructure Manager (VIM) to control. We will use openstack on single node devstack for this tutorial, following ​this guide.

Pre-Set up:
  1. omf load -t srv2-lg1.sb1.cosmos-lab.org -i tutorial-devstack.ndz -r 60
    1. You should see: INFO exp: 1 node successfully imaged ...
  2. omf tell -a on -t srv2-lg1.sb1.cosmos-lab.org
  3. Wait for the node to come up
  4. ssh native@srv2-lg1.sb1.cosmos-lab.org
  5. cd ~/devstack
  6. ./stack.sh

Commands will run for a while (about 10 minutes). If successful, it will output the credentials and address to login via the webui, and will look like the following:

This is your host IP address: 10.19.1.2
This is your host IPv6 address: ::1
Horizon is now available at http://10.19.1.2/dashboard
Keystone is serving at http://10.19.1.2/identity/
The default users are: admin and demo
The password: native

You will need the ip address, keystone url, user and password in the following steps.

Accessing the OSM WebUI

Both nodes are listening on port 80.

Redirect two ports over ssh, following This Guide

For example, forward 9901 → srv1-lg1:80 , 9902 → srv2-lg1:80

Or Linux example, commands run on your local machine: 

ssh testbeduser@sb1.cosmos-lab.org -N \
-L 9980:srv1-lg1:80 \
-L 9981:srv2-lg1:80

The web credentials are: admin / admin, running at the ip address of the first node.

If the webui doesn't come up:

  1. SSH to the node with the ssh credentials: native / native
  2. Check to see that all containers are running docker stack ps osm
  3. Try re-installing OSM by running ./install_osm.sh

Connecting OSM to the VIM

  1. Log into the OSM with admin/admin
  2. Click "VIM accounts" on the left bar
  3. Delete existing accounts with the trash can icon
  4. Add the new account for your openstack with the following information:
    • URL http://$DEVSTACK_IP/identity/v3/
    • User admin
    • password native
    • tenant admin
    • name openstack-site
    • Type: openstack
  5. Click create

Adding a disk image to openstack

  1. download the attachment cirros034 from this page
  2. in a new window, go to the openstack webui
  3. click images
  4. click create image
    • name: cirros034
    • image source: browse for the file you downloaded
    • format: qcow2
  5. click create image

Creating a VNF

  1. VNF package onboarding
    1. go to packages → vnf packages
    2. download the attachment cirros_vnf.tar.gz
    3. drag the downloaded file to the window
  2. NS package onboarding
    1. go to packages → ns packages
    2. download the attachment cirros_2vnf_ns.tar.gz
    3. drag it to the window
  3. Instantiate the NF
    1. click the launch icon and enter information
      • name
      • description
      • nsd_id: cirros_2vnf_ns
      • vim account id: openstack-site
  • use openstack ui to load console and ping
