OpenVIM installation to be used with OSM release 0
From OSM Public Wiki
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
Infrastructure requirements
In order to run openvim and be able to dataplane VNFs, some infrastructure requirements are missing: https://github.com/nfvlabs/openvim/wiki/Getting-started#requirements
Installation
Installation process is detailed link here. This will install required packages, openvim SW and Floodlight controller to control the underlay switch.
Configuration
Configuration details can be found here. For convenience
Configuring Floodlight Openflow Controller
- Go to scripts folder and edit the file **flow.properties** setting the appropriate port values
- Start FloodLight
service-openvim floodlight start #it creates a screen with name "flow" and start on it the openflow controller screen -x flow # goes into floodlight screen [Ctrl+a , d] # goes out of the screen (detaches the screen) less openvim/logs/openflow.0
Openvim server configuration
- Go to openvim folder and edit openvimd.cfg. By default it runs in 'mode: **test**' where neither real hosts nor openflow controller are needed. You can change to 'mode **normal**' to use both hosts and openflow controller.
- 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
Openvim client configuration
- Show openvim CLI client environment variables
openvim config # show openvim related variables
- Change environment variables properly
#To change variables run export OPENVIM_HOST=<http_host of openvimd.cfg> export OPENVIM_PORT=<http_port of openvimd.cfg> export OPENVIM_ADMIN_PORT=<http_admin_port of openvimd.cfg> #You can insert at .bashrc for authomatic loading at login: echo "export OPENVIM_HOST=<...>" >> /home/${USER}/.bashrc ...
Create a tenant in openvim to be used by OSM
- Create a tenant that will be used by OSM:
openvim tenant-create tenant name? admin tenant description (admin)? <uuid> admin Created
- Take the uuid of the tenant and update the environment variables used by openvim client:
export OPENVIM_TENANT=<obtained uuid> #echo "export OPENVIM_TENANT=<obtained uuid>" >> /home/${USER}/.bashrc openvim config #show openvim env variables
Additional configuration
Finally, compute nodes as well as external networks are required to be added to openvim. Details on how to it can be found here.
