Linux containers (LXC)[1] technology has taken off with Docker https://www.docker.com/ [2][3] which was released as open source in March 2013. RedHat and others have collaborated with the corporate backer to the technology seemingly to compete with Canonical's JuJu https://juju.ubuntu.com/ and Charm technology which also is based on Linux containers. Linux containers are built into the linux kernel, and so offer a lightweight native method of virtualization compared to more traditional (heavyweight) virtualization techniques like VMWare.
Installing on Ubuntu
https://docs.docker.com/installation/ubuntulinux/ Apparently the packaged version is old (not surprising). So, add the Docker repo, and install lxc-docker
Note: it's only supported on 64-bit Ubuntu
