Linux Containers (LXC), provides the ability to group and isolate of a set of processes in a jail by virtualizing and accounting the kernel resources. It is similar to Linux-Vserver or Openvz.
Please note that LXC is no longer using SourceForge for most of its resources.
Instead, we're now using github at http://github.com/lxc
Mailing-lists are still hosted here for the time being.
Very helpful for teaching advanced network technologies to my students !
