[Xen-devel] Problem booting on IBM e Server (xSeries 22)
I am having trouble booting domain 0 on this IBM hadware (SCSI
disk controller - aic7xxx). On the way up, domain 0 is failing to
mount root. This happens with both the 2.4 as well as the 2.6
kernel. The xen tree (along with the 2.4/2.6 kernels) is a few days
old. I have SuSe 9.0 installed on this box. Following are the lines
from my grub configuration file:
title Xen 2.0 / XenoLinux 2.6.7
kernel (hd0,1)/boot/xen.gz dom0_mem=431072 com1=115200,8n1
module (hd0,1)/boot/vmlinuz-2.6.7-xen0 root=/dev/sda2
console=tty0 console=ttys0
Any help would be greatly appreciated.
Regards,
K. Y

Also, I''ve noticed that linux 2.6 seems to ignore multiple console= atributes, so I''d stick to just one. The default 2.6.7 xen/linux kernel build has an aic7xxx driver in, but I''m not sure how much testing its had. The 2.4.26 kernel has received much wider testing, so you may want to stick with that to get things up and running. If you''re using the unstable tree you''d be well advised to ''bk pull; make world'' to sync with the repository as there''s been a number of bug fixes in the last couple of days. You might want to try adding ''ignorebiostables'' or ''noacpi'' to the xen command line to see if that makes a difference. The other thing to watch out for is that we don''t support devfs, so your fstab must contain proper /dev/sdXX entries rather than LABEL=/. (We plan to add udev functionality in due course.) If you can connect something to the machine''s serial port and capture the boot messages we''ll be in a much better position to see what''s going wrong. Capturing the output of booting an equivalent native linux kernel for comparison can be useful too. I''d be very surprised if we couldn''t get this machine going.
