It isn’t really as if the operating system ceases to exist. More to the point, it ceases to be a separate entity from the compiled application. A unikernel, therefore, is an indivisible unit of computing logic. As a microservice, it carries the promise of unlimited scalability. And as a virtual machine, it is designed to run under the Xen Type 1 (hardware-level) hypervisor.

linuxcontainers.org is the umbrella project behind LXC, LXD, LXCFS and CGManager.
The goal is to offer a distro and vendor neutral environment for the development of Linux container technologies.
Our main focus is system containers. That is, containers which offer an environment as close to possible as the one you’d get from a VM but without the overhead that comes with running a separate kernel and simulating all the hardware.
