Xen Case Study - Building a Time Machine

Here is the first new “case study” from the new Xen Around the World Project. Scot Stevenson detailed a project to use Xen for the creation of a backup Time Machine server.
Info from Scot:
These are my notes on how I set up a Ubuntu Linux server at home to provide Time Machine backup and home video storage to our MacBooks. It is a simple step-by-set list of what I did, with very little background on the why. I wrote this text for myself so it will easier to do it all over again if alien face-huggers burst through the floor and destroy the computer with their acid blood. I am publishing it on the Internet in case somebody else has a similar project in the works.
