Problem on FC3
I'm getting a VFS kernel panic when trying to booting to FC3 from Xen.
Its the one that says I must supply a valid "root=" option. (sorry I
don't have it verbatim.)

I'm using the xen-2.0 binary installer, kernel 2.6.9. I am using
ext3fs, but I am fairly certain that I have compiled support into the
kernel. (I've tired compile xen from the 2.0 and nighltly source too :-).

I've tired Keir's suggestions but to no avail... I'm fairly new to
linux, but not to unix. I'm just don't know what to try next.

Suggestions?

Here's my setup:

Device Boot
/dev/hdc1
/dev/hdc2 FreeBSD
/dev/hdc3 FC3 Boot (ext3fs)
/dev/hdc4 Extended
/dev/hdc5 FC3 Root (ext3fs)
/dev/hdc6 FC 3 swap

I've also got other partitions.

Grub.conf:

default=0
timeout=5
splashimage=(hd1,2)/grub/splash.xpm.gz
hiddenmenu

title Xen 2.6 / XenLinux
kernel /xen.gz dom0_mem=131072 console=vga
module/vmlinuz-2.6.9-xen0 root=/dev/sdc5 ro console=tty0
module /initrd-fc3.img
title Fedora Core (2.6.9-1.667)
root (hd1,2)
kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.9-1.667.img

Contents of boot partition, root(hd1,2):

-rw-r--r-- 1 root root 50929 Nov 2 11:53 config-2.6.9-1.667

Your GRUB config is wrong -- it should specify 'root=/dev/hdc5', not
sdc5.

Wow, I feel stupid. SCSI versus IDE, doh! I'll give it a shot.
