Xen users - Jul 2006 - debian stable/ xen-3.0.2-2/scsi: cannot boot.

I cannot boot my xen kernel.

System: debian sarge, up to date.
Machine: PIII + scsi disks (only scsi disks).

Installation:
-------------
 I download xen-3.0.2-install-x86_32p.tgz;
 tar xzf ....
 cd xen-3.0.2-2-install
 sh ./install.sh

 Everything seems ok (no warning).

Let us look at /boot/grub/menu.lst
-----------------------------------
 1) configuration for the classical kernel (not the xen one):

title           Debian GNU/Linux, kernel 2.6.8-1-386 (recovery mode)
root            (hd0,2)
kernel          /vmlinuz-2.6.8-1-386 root=/dev/sda2 ro single
initrd          /initrd.img-2.6.8-1-386
savedefault
boot
          This works perfectly.

 2) configuration for the xen kernel:

title Xen 3.0 / XenLinux 2.6
root            (hd0,2)
kernel /xen-3.0.gz dom0_mem=262144
module /vmlinuz-2.6-xen root=/dev/sda2 ro console=tty0

Booting:
-------
When I try to boot the xen kernel, boot sequence starts and abort with
the classical message "please append a correct root=..."

but, for me, root=/dev/sda2 is correct:
>mount
/dev/sda2 on / type ext3 (rw,errors=remount-ro)
.....

* Do I need an initrd? Ok, lets try:
>mkinitrd -o initrd-2.6.16-xen 2.6.16-xen
I get:
FATAL: Could not load /lib/modules/2.6.16-xen/modules.dep: No such file
or directory
and no initrd is created...

....? help!

Thank you in advance.

Before tryiing the follwing make sure you have new kernel under
/lib/module (you will see 2.6.16-xen) If it is there Try the
follwoing.

   # cd /boot/
   # depmod 2.6.16-xen
   # mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod
initrd-2.6.16-xen.img 2.6.16-xen

That should fix the problem

mmmhhh... no. mkinitrd do not support these options -v and -f, nor
 --with=aacraid --with=sd_mod --with=scsi_mod :
>mkinitrd  -f --with=aacraid --with=sd_mod --with=scsi_mod -o
>initrd-2.6.16-xen.img 2.6.16-xen
/usr/sbin/mkinitrd: illegal option -- f
>mkinitrd   --with=aacraid --with=sd_mod --with=scsi_mod -o
>initrd-2.6.16-xen.img 2.6.16-xen
/usr/sbin/mkinitrd: illegal option -- -

Hi,all.
This is the difference of distribution.
In RHEL, mkinitrd suports these options.
See "man mkinitrd" in detail.

try doing a depmod -a before running mkinitrd.

On Debian-based systems the command is mkinitramfs, I don''t have the
syntax at hand now.
on SuSE it''s also mkinitrd, but it has a different systax afaik.

Maybe this should be put in the xen manual, because it is quite
misleading in this aspect.
