In short, gain with minimal pain, a couple of small hitches. I went single-core to dual-core with a drop-in replacement CPU and it was almost as easy as replacing the batteries in a flashlight.
I have a VPS hosted at RimuHosting.com. I waited a while (3 months) for bugs to be squashed before upgrading it to Ubuntu Linux 7.10 (”Gutsy Gibbon”). There was one new issue.
BTW, my non-Rimu home server was the first thing I updated. Notes are here.
The only Xen wrinkle is that you need the libc6-xen package. I don’t know if that’s in Feisty or not. In my case I experienced a slew of scary Segmentation Fault errors in the package configuration stage. I found :this post which contains a solution for the problem. But if possible you might want to try installing that package before upgrading. If that doesn’t work, just use the method described in that post.
After doing that and running dpkg --configure -a, it was okay. It did complain about AppArmor and being unable to do something with modules, but that seems to be not germane to Xen so I ignored it and rebooted, and everything seems fine.
A few weeks ago I updated to the latest version of Ubuntu Linux. This is the 7.10 (meaning October 2007) release, called “Gutsy Gibbon”. I encountered a couple of serious issues early on, but now that these are resolved things are running well. I’ll describe the issues and solutions so that anyone else encountering them can easily overcome them.

A friend who is working primarily in the J2EE technology world (as I was, until early 2006) asked me for a how’s-it-going with respect to Ruby and Rails.

- Rails is over-hyped, but it’s still quite good (definitely not perfect)
- I like the productivity of Ruby on Rails but I wouldn’t call it a silver bullet by any means
- Ruby performance was bad and is getting less bad, and can even be good if you do what the experts say
- The real gem (har har) in the Ruby and Rails space is the community itself

7.04 (meaning “the major release planned for 2007/04″, not meaning “the minor release following 7.03″) was released on April 19th. I upgraded today and it went pretty well, with a bit of manual cleanup required. More details after the jump. Read the rest of this entry »
