Oh, dear. I hate it when that happens.

That's like saying its a 'black car' or 'brick house'. If you give more
details you're more likely to reach someone with a similar issue.

Either the initrd is failing to load a module needed to see the drive,
or its file system. Not everyone here uses SLES, so if you could be more
specific about your xen version and kernel, it would help.

Odd question, USB keyboard? I saw the serverworks chipset and curious if
it relates to another problem I had on (what I suspect is) a similar
board.

This IDE chipset is known to be buggy at best. You may want to consider
a PCI controller for your drives, you'd get better performance. The
generic IDE driver however should suffice.

Ok, so it is reiserfs , and your initrd is loading it.. must be the IDE
driver.

While I'd love to encourage you to continue trying to get this to work,
I want to reiterate that your IDE chipset is .. well, yucky. If you have
a spare $15 - $20 , go get a PCI controller, and you'll (probably) find
the problem goes away and the drives end up spinning better.
Best,
