==Configuring openvim 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

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 in the
  • Base image: ubuntu-14.04.4-server-amd64

Installing required packages and libraries

  • Install required packages
sudo apt-get install mysql-server git 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

Openvim is still part of the github openmano repository. These instructions download all components, but just configure the openvim-related aspects.

  • Clone the git repository:
git clone https://github.com/nfvlabs/openmano.git openmano
  • 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
openmano/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 ${PWD}/openmano/openvim/openvim /home/${USER}/bin/openvim
ln -s ${PWD}/openmano/scripts/service-openmano.sh /home/${USER}/bin/service-openmano

Configuring

Configuring openvim server

  • Go to openvim folder and edit openvimd.cfg.
  • Start openvim server
service-openmano openvim start
#it creates a screen with name "vim" and starts inside the "./openvim/openvimd.py" program
screen -x vim                             # goes into openvim screen
[Ctrl+a , d]                              # goes out of the screen (detaches the screen)
less openvim/logs/openvim.0
