Link: Setting Up Multiple Isolated Linux Systems (Containers) Using LXC On Ubuntu 14.04

LXC, Linux Containers, is a fast, lightweight, and operating system-level virtualization technology that allows us to host multiple isolated Linux systems (Containers) in a single host.

All guests will efficiently shares the resources such as CPU, RAM, Hard disk, and network etc of your original host computer.
