Hello,
My Xen-ified kernel (3.0.3) on a dedicated host seems to be kernel-
panicing upon boot. Since IPMI/SOL seems to be nonfunctional in the
Xen kernel, I cannot tell what is causing the kernel to panic.
SOL works (for SOL definitions of works...) fine for me on an IBM
x366. What are your Xen and Linux command line options? do you have
SOL working with a stock Linux kernel?
Yes - it works on a default RHEL kernel. I've tried several times to
fix it to no luck...

So I thought I'd check /var/log/messages. But to my surprise, that
also seems to have no output for any messages generated by the Xen
kernel. Why? (The default RHEL4.4 kernels seems to log to this file
just fine, and I've checked syslog.conf which looks fine).
If you panic before mounting the root file system, there's no file
system to write the log output to.
D'oh, good point. *Sighs* Guess I'm up a creek without a paddle.
