Neutron Extension to add a console to Virtual Router

I have written a small extension to Neutron to add a console to virtual routers. This can help the tenant in understanding the networking setup and debugging. The console provides a very limited set of commands to be executed with in the virtual router (linux network namespace).

The demo shows a proof-of-concept of the idea, although the demo shows the console working with Linux network namespace, it can be easily adapted to other implementations.

The CLI of the console is very configurable.

Here is the video


Test driving LXD


LXD is an OS container (unlike docker which is application level container) and provides a more complete OS user space environment. It is a improved version of LXC containers. It provides image management, live migration of container instances, OpenStack integration.

LXD is composed of two components the server daemon called ‘lxd’ while the client is called ‘lxc ‘


The latest version of LXD can be installed from the ppa repository

sudo add-apt-repository ppa:ubuntu-lxc/lxd-git-master
sudo apt-get update
sudo apt-get install lxd

Image repositories

You will need a LXC image to start your container. To get a container image you have to add a LXC image repository location

sudo lxc remote add images –debug
sudo lxc remote list


Next you can import the LXC image

sudo lxd-images import lxc ubuntu trusty amd64 --alias ubuntu --alias Ubuntu
sudo lxc image list


Starting your Linux Container instance

sudo lxc launch ubuntu u1
sudo lxc list

sudo lxc exec u1 /bin/bash
