[Xen-users] Kernel Panic - SuSE (RAID+LVM)

[Tiago Cruz <tiagocruz@xxxxxxxxx>]

Hello guys,

I'm trying to run XEN installed from RPM's packages on my server with
SUSE LINUX Enterprise Server 9 (x86_64) kernel 2.6.5-7.257-smp and the
problem when I reboot is the follow:

VFS: Monted root (ext2 filesystem)
VFS: Cannot open root device "system/root_lv" on unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic = not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I've searched on old posts, and tried to make other initrd image, but
without success :-(

This kernel works on my grub:
title Linux
    kernel (hd0,0)/vmlinuz root=/dev/system/root_lv selinux=0 splash=silent 
desktop elevator=as showopts
    initrd (hd0,0)/initrd

This kernel don't work:
title Xen
    kernel (hd0,0)/xen-3.gz com1=115200,8n1 noreboot
    module (hd0,0)/vmlinuz-2.6-xen root=/dev/system/root_lv ro maxcpus=1 
console=tty1 console=ttyS0,115200n8
    module (hd0,0)/initrd-2.6-xen.img


My RAID controller is:
0000:02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID
controller 4 (rev 06)

My fstab:
xen:~ # cat /etc/fstab 
/dev/system/root_lv  /                    reiserfs   defaults              1 1
/dev/sda1            /boot                reiserfs   defaults              1 2
/dev/system/home_lv  /home                reiserfs   defaults              1 2
/dev/system/logs_lv  /logs                reiserfs   defaults              1 2
/dev/system/queue_lv /queue               reiserfs   defaults              1 2
/dev/system/tmp_lv   /tmp                 reiserfs   defaults              1 2
/dev/system/var_lv   /var                 reiserfs   defaults              1 2
/dev/system/swap_lv  swap                 swap       pri=42                0 0

Is this problem arround RAID and/or LVM?

Thanks!
