| - | LXC is a tool to create and manage containers. It contains a full featured container with the isolation / virtualization of the pids, the ipc, the utsname, the mount points, /proc, /sys, the network and it takes into account the control groups. It is very light, flexible, and provides a set of tools around the container like the monitoring with asynchronous events notification, or the freeze of the container. This package is useful to create Virtual Private Server, or to run isolated applications like bash or sshd. | + | [[https://linuxcontainers.org/lxc/|LXC]] is a tool to create and manage containers.
