 ====== LXC - Linux Container Tools ======
-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.

+LXC is pretty low level, very flexible and covers just about every containment feature supported by the upstream kernel. For a completely fresh and intuitive user experience with a single command line tool to manage your containers see [[LXD]].

 first boot with ''hwaddr'' line disabled, look what the random address was assigned, set it in config.
