After the initial struggles to get Xen working properly on my Asus P5B based server, I added my Hauppauge PVR-500 TV card in the equation. One of the main objectives of the Xen project was to be able to isolate my MythTV setup from my webserver and mailserver.
Badly enough, this is what happened when I tried to load the module in the kernel:

Linux video capture interface: v1.00
PCI: Enabling device 0000:00:00.0 (0000 -> 0002)
PCI: Setting latency timer of device 0000:00:00.0 to 64
ivtv: ==================== START INIT IVTV ====================
ivtv: version 0.6.6 (tagged release) loading
ivtv: Linux version: 2.6.16.42-xen SMP gcc-4.1
ivtv: In case of problems please include the debug info between
ivtv: the START INIT IVTV and END INIT IVTV lines, along with
ivtv: any module options, when mailing the ivtv-users mailinglist.

On Jan 2nd, my server was compromised using a vulnerability in my cacti installation. This machine hosts all my files, my emails, my photo's, but also serves as mythbackend and asterisk voip server and therefore, I have to admit that I felt quite exposed after this event (although, to my best knowledge, no files were changed and only a spambot was listening).

I decided to upgrade my server and use Xen to logically separate the different functions from each other. I'm an enthusiastic Gentoo user for the last 4 years, so I used that distribution as a foundation.

One of the first challenges was to get the kernel to work with all the new hardware. When I first installed Xen, the latest version in portage was 3.0.2 with kernel 2.6.16.28. This kernel still had some issues with regards to the ATAPI support in libsata:
