The devstack project is an interesting tool to deploy a complete OpenStack development environment from source code. I’ve been using it from one year in my development activities on Neutron. For that, I set up an isolated VM (libvirt or VirtalBox through Vagrant), but I found that environment isn’t very efficient (too slow and uses lot of memory). Furthermore, when you developing network stack, you need to set up more than one node (three is a good number to test network virtualization). This is why I try to set up that environment into containers (LXC). Setup LXC environment I work on Debian testing release (Jessie) which uses the kernel 3.11 release. devstack supports Debian distribution thanks to the Emilien Macchi’s commit . I use LXC experimental Debian package to be able to use the new template ‘lxc-debconfig’ which is more efficient when deploying a Debian container and; it can use preseed config file to set up the container: $ sudo 'deb http://ftp.debian.org/debian
