I am trying to install Xen/Xenolinux v1.1 on my workstation which has 2
SCSI disks. The first disk has WinXP installed, and the second disk has
Redhat 8.0. I copied the images into /boot and modified grub.conf

title Xen / XenoLinux 2.4.22
        root (hd1,0)
        kernel /xen.gz dom0_mem=131072 ser_baud=115200 noht noreboot
        module /xenolinux.gz root=/dev/sdb2 ro console=tty0

When I reboot the machine and select Xen, I have the following error

kmod: failed to exec /sbin/modprobe -s -k block-major-8, errno=2
VFS: Cannot open root device "sdb2" or 08:12
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:12

Xen seems to start but Xenolinux does not. My guess is that my SCSI
adapter is not recognized by XEN. My machine uses the following adapter:
LSI Logic. If it is the case, do you know how I could include support
for this adapter in Xen?

I was lucky and could install Xen on another machine and it works fine
(although this time the network card is not recognised). The application
I've tried is even faster when running on Xen that on the native Linux

Many thanks in advance.

Guillaume Belrose.
