Setting up XEN on a Hetzner Dedicated Server (EX-series)

Author: Michael van Rooijen (@meskyanichi)

DISCLAIMER: I am a programmer, not a sysadmin in my day-to-day life. I provide this guide simply as a self-reference, and as a way to contribute to the community of developers. The main motivation for writing this guide is because of the lack of properly written guides/tutorials. They were either out-dated, inaccurate, in a non-English language or simply too vague to understand (at least for me, as a programmer and not a sysadmin).

I hope this guide helps getting you up and running with your own collection of VPS's on your own Dedicated Server over at Hetzner.de.
