The only two issues I have, neither of which are to do with the virtulisation, are the photographic gallery which can no no longer perform rewrites correctly and my weather station is down.

While planing my move to Orkney, I need to move my web servers from their current home in southern England to the island, with as little disruption as possible. Picking it up and transporting it would require a down time of around 3 or 4 days, which I considered unacceptable.
This article investigates the alternatives I considered and results in a host system that houses a selection of Virtual Machines (VMs) to overcome this some and other problems.
