Hyper

This guide is a step-by-step procedure on how to setup Hyper on Linux, with Xen Hypervisor. The complete documentation, with installation instructions for other platforms, can be found on Hyper's official documentation.

What is Hyper?

Hyper is a set of Linux kernel, init process and management tools, able to virtualize containers to improve their isolation and management in case of multi-tenant applications, eliminating the need of guest OS and all the components it brings. Hyper provides safe and fast isolated environments (virtual machines), on which portable environments (containers) can be easily scheduled.

Prerequisite

• QEMU 2.0 (or later)
• Docker 1.5 (or later)
