<h1>LXC container driver</h1>
|

<p>
|
||||
The libvirt LXC driver manages "Linux Containers". Containers are sets of processes
|
||||
with private namespaces which can (but don't always) look like separate machines, but
|
||||
do not have their own OS. Here are two example configurations. The first is a very
|
||||
light-weight "application container" which does not have it's own root image. You would
|

start it using
