OpenVIM installation to be used with OSM release 0

VM creation

• Requirements:
  • 1 vCPU (2 recommended)
  • 2GB RAM (4 recommended)
  • 40GB disk
  • 3 network interfaces to:
    • OSM network (to interact with RO)
    • DC intfrastructure network (to interact with the compute servers and switches)
    • Telco/VNF management network (to provide IP addresses via DHCP to the VNFs)
• Base image: ubuntu-14.04.4-server-amd64

Installing required packages and libraries

• Install required packages

sudo apt-get install mysql-server git subversion screen wget python-yaml python-libvirt python-bottle \
  python-mysqldb python-jsonschema python-paramiko python-argcomplete python-requests

• Configure python-argcomplete

activate-global-python-argcomplete --user
echo ". /home/${USER}/.bash_completion.d/python-argcomplete.sh" >> ~/.bashrc

Building and installing the module

• Clone the git repository:

git clone https://github.com/nfvlabs/openmano/openvim openvim

• Database creation

mysqladmin -u root -p create vim_db

• Grant access privileges from localhost. Go to mysql console and use the following commands to create user vim and grant privileges to the databases:

mysql> CREATE USER 'vim'@'localhost' identified by 'vimpw';
mysql> GRANT ALL PRIVILEGES ON vim_db.* TO 'vim'@'localhost';

• Initialize database

openvim/database_utils/init_vim_db.sh -uvim -pvimpw

• Add openvim client and scripts to the PATH. It is enough to create the /home/${USER}/bin/ folder and add there the appropriate links:

mkdir /home/${USER}/bin/
ln -s ${PWD}/openvim/openvim /home/${USER}/bin/openmano
ln -s ${PWD}/openvim/scripts/openmano-report.sh /home/${USER}/bin/openmano-report
cd /home/${USER}/bin/
wget 
ln -s ${PWD}/openmano/scripts/service-openmano.sh /home/${USER}/bin/service-openmano

Configuring

Configuring openvim server

• Go to openmano folder and edit openmanod.cfg.
• Start openmano server

service-openmano openmano start
#it creates a screen with name "mano" and starts inside the "./openmano/openmanod.py" program
screen -x mano                             # goes into openmano screen
[Ctrl+a , d]                               # goes out of the screen (detaches the screen)
less openmano/logs/openmano.0

Configuring openmano client

• Let's configure the openmano CLI client. This is only necessary if you have changed the file 'openmanod.cfg'
• List the environment variables

openmano config                      #show openmano env variables

• Update the environment variables accordingly:

export OPENMANO_HOST=<http_host of openmanod.cfg>
export OPENMANO_PORT=<http_port of openmanod.cfg>
openmano config                      #show openmano env variables

Create an openmano tenant, a datacenter based on openvim and attach the tenant to the datacenter

• Let's create a new tenant:

openmano tenant-create mytenant --description=tenant-description
openmano tenant-list                           #show list of tenants uuid and name

• Take the uuid and update the environment variable associated to the openmano tenant:

export OPENMANO_TENANT=<obtained uuid> 
openmano config                                #show openmano env variables

• Let's create a new datacenter 'mydc' in openmano. This datacenter will use openvim as a VIM, and the VIM tenant id is "admin"

openmano datacenter-create mydc http://localhost:9080/openvim
openmano datacenter-list --all                           #show all datacenters
openmano datacenter-attach mydc --vim-tenant-id <uuid>   #attach the datacenter mydc and openvim tenant id to the openmano tenant 'mytenant'
openmano datacenter-list                                 #show datacenters associated to our tenant
openmano datacenter-net-update mydc
Edit datacenter mydc (y/N)? y
