Overview

LinuX Containers (LXC) provide lightweight virtualization that lets you isolate processes and resources without the need to provide instruction interpretation mechanisms and other complexities of full virtualization.

Notes

Upstream libvirt support LXC.
KVM + LXC can function properly on same host.
LXC inside KVM works properly on same host.
LXC take advantage of KMS feature of new Kernels.
64bit OS using a 32bit container.
LXC works well with btrfs.
No special hardware required.
No patch is required to the kernel, since LXC is already integrated into the Kernel.
OpenVZ Containers run on LXC, only Config modification required.

User case examples

Isolate single processes, (I.E. a webserver).
VPS
LTSP
Software build, testing, upgrading (think sandboxing)

kernel requirements

The Linux container capabilities are part of the main stream linux kernel and require kernel version >= 2.6.27 (well working as of 2.6.31).

There are no requirements to compile a kernel or apply patches.

User space tools (lxc)

The user space tools, or lxc, are a set of scripts that manage linux containers.

You may install the lxc user space tools from the Ubuntu repositories.

sudo apt-get install lxc

Or download the latest stable package from sourceforge and compile them yourself. The lxc project maintains a git repository for a bleeding edge set of tools.

Networking

There are several networking options available, the consensus appears to be that bridging your network card is the best option. As such I will cover bridging your network card here, hopefully this information can be expanded.
