Hi,
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
accordingly:
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
message:
root_device_name=sdb2
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.

Take a look at ''xen/drivers/scsi'' One thing that''s particular tricky about porting drivers from Linux to Xen is that: Linux is thread-driven whereas Xen is event-driven. If you want to port the scsi driver, the best way is to look at the ''diff -u'' of Xen BusLogic and Linux BusLogic, and post questions to the list. -- Bin ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.

If the LSI logic adaptor you''re referring to is the "Fusion MPT" adaptor, then there is a patch in the works (by Stephen Evanchik) which handles it. Have a look at http://www.clarkson.edu/~evanchsa/xen/ for the current patch, which is working but is still under testing (there seem to be a few performance issues, but no stability issues), and will be submitted to the unstable tree in due course.
