Moving VM hosts with ubuntu install

[Stephen]

a weird little LAMP (weird fro the tasks its doing more than install)
lots of little things installed some of which are not in the normal
repos i have found. and it started as a dev box and then was moved to
production as the tools were intensely popular.

The Xenserver is getting decommissioned in favor of a different
platform (as it is nearly impossible to convert Xen VM's to anything
else)

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
