OSM Release ONE

Open Source MANO (OSM) is the open source community that aims to deliver a production-quality MANO stack for NFV, capable of consuming openly published information models, available to everyone, suitable for all VNFs, operationally significant and VIM-independent. OSM is aligned to NFV ISG information models while providing first-hand feedback based on its implementation experience.

Interaction with VIMs and VNFs

The following figure shows OSM interaction with VIM and VNFs.

In simpler setups, OSM only requires a single interface as long as both VIM and VNF IP addresses are reachable

Install OSM

Install from source

All you need to run OSM Release One is a single server or VM with the following requirements:

• 8 CPUs, 16 GB RAM, 100GB disk and a single interface with Internet access
• Ubuntu16.04 as base image (http://releases.ubuntu.com/16.04/), configured to run LXD containers. If you don't have LXD configured, you can follow the instructions here (LXD configuration)

Once you have prepared the host with the previous requirements, all you need to do is:

wget https://osm-download.etsi.org/ftp/osm-1.0-one/install_from_source.sh
chmod +x install_from_source.sh
./install_from_source.sh

After some time, you will get a fresh OSM Release One installation. You can access to the UI in the following URL (user:admin, password: admin):

https://your_local_ip:8443

Make sure that port 8443 is accessible, as well as the following required ports: 8000, 4567, 8008, 80, 9090.

As a result of the installation, three LXD containers are created in the host: RO, VCA, and SO-ub (running the SO and the UI), as shown in the figure below.

Adding a VIM account

Before proceeding, make sure that you have a site with a VIM configured to run with OSM. Three different kinds of VIMs are currently supported by OSM:

• OpenVIM. Check the following link to know how to install and use openvim for OSM: OpenVIM installation (Release One)
• OpenStack. Check the following link to learn how to configure OpenStack to be used by OSM: Openstack configuration (Release ONE)
• VMware vCloud Director. Check the following link to learn how to configure VMware VCD to be used by OSM: Configuring VMware vCloud Director for OSM Release One

OpenVIM site

• Go into the RO container:

lxc exec RO -- bash

• Execute the following commands, using the appropriate parameters (e.g. site name: "openvim-site", IP address: 10.10.10.10, VIM tenant: "osm")

export OPENMANO_TENANT=osm
openmano datacenter-create openvim-site http://10.10.10.10:9080/openvim --type openvim --description "Openvim site" 
openmano datacenter-attach openvim-site --vim-tenant-name=osm
openmano datacenter-list
exit     #or Ctrl+D to get out of the RO container

Openstack site

• Go into the RO container:

lxc exec RO -- bash

• Execute the following commands, using the appropriate parameters (e.g. site name: "openstack-site", IP address: 10.10.10.11, VIM tenant: "admin", user: "admin", password: "userpwd")

export OPENMANO_TENANT=osm
openmano datacenter-create openstack-site http://10.10.10.11:5000/v2.0 --type openstack --description "OpenStack site"
openmano datacenter-attach openstack-site --user=admin --password=userpwd --vim-tenant-name=admin
openmano datacenter-list
exit     #or Ctrl+D to get out of the RO container

VMware site

• Go into the RO container:

lxc exec RO -- bash

• Execute the following commands, using the appropriate parameters (e.g. site name: "vmware-site", IP address: 10.10.10.12, VIM tenant: "vmware-tenant", user: "osm", password: "osm4u", admin user: "admin", admin password: "adminpwd")

openmano datacenter-create vmware-site https://10.10.10.12" --type vmware --description "VMware site" --config '{admin_password: adminpwd, admin_username: admin}'
openmano datacenter-attach vmware-site --user=osm --password=osm4u --vim-tenant-name=vmware-tenant
openmano datacenter-list
exit     #or Ctrl+D to get out of the RO container

Note: The name of the site/datacenter "vmware-site" has to match the name of the organization of "vCloud Director". Inside this organization the tenant "vmware-tenant" must exist

Deploying your first Network Service

In this example we will deploy the following Network Service, consisting of two simple VNFs based on CirrOS connected by a simple VLD.

Before going on, download the required VNF and NS packages from this URL: https://osm-download.etsi.org/ftp/examples/cirros_2vnf_ns/

Uploading VNF image to the VIM

Get the cirros 0.3.4 image from the following link: http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

Then, onboard the image into the VIM. The instruction differs from one VIM to another:

• In Openstack:

openstack image create --file="./cirros-0.3.4-x86_64-disk.img" --container-format=bare --disk-format=qcow2 --public --property location="/mnt/powervault/virtualization/osm/CirrOS/cirros-0.3.4-x86_64-disk.img" cirros034

• In openvim:

openvim image-create --name cirros034 --path /mnt/powervault/virtualization/osm/CirrOS/cirros-0.3.4-x86_64-disk.img

Onboarding a VNF

• From the UI:
  • Go to Catalog
  • Click on the import button, then VNFD
  • Drag and drop the VNF package file cirros_vnf.tar.gz in the importing area.

• From the SO CLI:
  • Step by step instructions TBC

Onboarding a NS

• From the UI:
  • Go to Catalog
  • Click on the import button, then NSD
  • Drag and drop the NS package file cirros_2vnf_ns.tar.gz in the importing area.
• From the SO CLI:
  • Step by step instructions TBC

Instantiating the NS

• From the UI:
  • Go to Launchpad > Instantiate
  • Select the NS descriptor to be instantiated, and click on Next
  • Add a name to the NS instance, and click on Launch.

• From the SO CLI:
  • Step by step instructions TBC

Wait for the message that the NS has been successfully deployed, and that's all!
