I finally got around to upgrading the server that serves this very page you’re reading to Ubuntu Jaunty today, up from Ubuntu Hardy. Yes I know, maybe I should have waited for Karmic, or even Lucid, but the biggest reason why I did this was that I’ve migrated this server from the little Pentium 4 Shuttle XPC that was in use before onto a Virtualbox 3.0.6 headless VM hosted on an Ubuntu Jaunty box running on top of an Intel E5200 CPU.

You’re probably wondering why I’d use an E5200 when it doesn’t have hardware virtualisation features built in? Well, the server consumes very little juice compared to the Pentium 4 (26% less in fact), it’s more powerful, it’s cheap, cheerful, produces less ambient heat, is a heck of a lot quieter and there’s loads of CPU time left over to do other things outside of the VM on the host side.

CPU wise, when the server gets really busy I’ve seen spikes as high as 50%, but it never exceeds that, so as far as I’m concerned, it’s fine. If I ever need this box to do anything more significant, I’ll upgrade the CPU to something that does have VT-x later on.

If you see anything unusual/missing/dead from today onwards, please let me know in a comment!
