Although Ubuntu is a breeze to use, I was becoming quite frustrated with it in that I wanted to do things that it didn't support without heavy amounts of additional work (for someone who's wedged OpenFire, SparkWeb, Asterisk, PmWiki, Alfresco, KnowledgeTree, IRC, MythTV, Moodle, Namazu, Munin, and StatusNet into the same box, it's saying a lot).
The extremely hard part was getting Xen to run. Ubuntu specifically supports KVM while avoiding Xen support. While a few, very talented individuals have gotten Xen to run with an Ubuntu DOM0, I'm not one of them. I'm a Xen n00b. So I went looking.
While at the South East Linux Fest, someone passed me disks for Suse Linux Enterprise 11 and OpenSuse 11.2. SLE 11 does exactly what I currently want/need. The probelm is that I can't justify buying the Enterprise license for home use.
Fortunately, OpenSuse 11.2 supports most of my requirements with a marginal amount of trouble. If you're following the wiki, you'll notice updates to various articles as I update them to reflect changes required for OpenSuse. Example: Setting up LIRC for MythTV with a MCE USB remote on OpenSuse 11.2.
For those with access to my system, I'll be working to get the background services back online. For now, OpenFire, SparkWeb, and PmWiki are back up. The rest will show up as I get the time to work on them.
