Re: [Xen-users] xen SUSE 9.3 ReiserFS domU not finding root fs

[Daniel <daniel@xxxxxxxxxxx>]

Thanks for your help!
That line "INITRD_MODULES="reiserfs" is in /etc/sysconfig/kernel the 
module seems to be loaded:
...
ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
Loading kernel/drivers/ide/pci/piix.ko
Loading kernel/drivers/scsi/aic7xxx/aic7xxx.ko
Loading kernel/drivers/scsi/megaraid.ko
Loading kernel/drivers/ide/ide-disk.ko
Loading kernel/drivers/cdrom/cdrom.ko
Loading kernel/drivers/ide/ide-cd.ko
Loading kernel/fs/reiserfs/reiserfs.ko
Waiting for device /dev/sda1 to appear:  ok
rootfs:  major=8 minor=1 devn=2049
Mounting root /dev/sda1
mount: No such device
Kernel panic - not syncing: Attempted to kill init!
<0>Rebooting in 1 seconds..

but something still goes wrong. Anybody uses XEN from the stock suse 9.3 
with reiserfs?
Is it correct to specify initrd for xen in the config file like this: 
ramdisk = "/boot/initrd-2.6.11.4-20a-xen"?
thanks,
dan
