What's LXC?

LXC is a userspace interface for the Linux kernel containment features.
Through a powerful API and simple tools, it lets Linux users easily create
and manage system or application containers.


Current LXC uses the following kernel features to contain processes:

LXC containers are often considered as something in the middle between a chroot and
a full fledged virtual machine. The goal of LXC is to create an environment as close as possible
to a standard Linux installation but without the need for a separate kernel.


LXC is currently made of a few separate components:


LXC is free software, most of the code is released under the terms of the GNU LGPLv2.1+ license,
some Android compatibility bits are released under a standard 2-clause BSD license
and some binaries and templates are released under the GNU GPLv2 license.

The default license for the project is the GNU LGPLv2.1+.


LXC's stable release support relies on the Linux distributions
and their own commitment to pushing stable fixes and security updates.

Based on the needs and available resources from the various distributions,
specific versions of LXC can enjoy long term support with frequent bugfix updates.

Other releases will typically be maintained on a best effort basis which
typically means until the next stable release is out.

Commercial support for LXC on Ubuntu LTS releases can be obtained from Canonical Ltd.

Extended support

LXC 1.0 and LXC 2.0 are long term support releases.
LXC 1.0 will be supported until June 1st 2019 and LXC 2.0 until June 1st 2021.

This is thanks to Canonical Ltd and Ubuntu who include
the long term support releases of LXC into their own LTS releases and work closely
with LXC upstream to maintain our stable branches.
