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. Unlike other virtualization methods such as VirtualBox, KVM, and Vmware, the guest systems uses the same kernel of the host system. All guests will efficiently shares the resources such as CPU, RAM, Hard disk, and network etc of your original host computer. The main goal of LXC is to create a Linux environment as close as a standard Linux installation, but without the need for a separate kernel.
