Boot up with the standard (non XEN) kernel and try to create initrd
image for XEN Dom0 then. After you have initrd created update your
menu.lst with new initrd. Your current initrd isn't right one because
it contains modules form the old kernel. They can't be loaded.

Hi everyone, here's my problem with xen 3.0.2: I've installed XEN on a
debian sarge 2.6.8.2 (IBM bi-xeon 3.2/1goRAM/HD scsi)
Here's how my boot launcher looks like:

title Xen 3.0 / XenLinux 2.6
root (hd0,0)
kernel /boot/xen-3.0.gz dom0_mem=100000
module /boot/vmlinuz-2.6-xen root=/dev/sda1 ro console=tty0
module /boot/initrd.img-2.6.8-2-386


....and there goes my "hapy" dom0 kernel panic on boot

« VFS: Cannot open root device "sda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(0,0) »


I've searched a lot about this, trying to remove/add module lines in my
menu.lst, and i think the problem is due to SCSI driver). On the dmesg
of my debian, it says :

« Fusion MPT base driver 3.01.09
Fusion MPT SCSI Host driver 3.01.09 »

If anyone know about SCSI support (how to add a driver into sources ?
where to find it ?) or if there's a way out with mkinit (or smthing like
that), i would appreciate a lot !!


thx in advance.
