debian squeeze xen after migration

[Pascal Bénistant]

Hello

I'm migrating a Lenny/2.6.26-2-xen-686 kernel
 lvm file based DomU to a new Squeeze Dom0 server running kernel
2.6.32-5-xen-686
xen-hypervisor-4.0-i386 xen-tools 4.2-1 .

when i use command

xm create test4.domain.fr.cfg

it starts, but then when I login with xm console I get:

[    0.098932] Write protecting the kernel read-only data: 968k
Loading, please wait...
[    0.128120] udev[47]: starting version 164

Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/xvda1 does not exist.  Dropping to a shell!


BusyBox v1.17.1 (Debian 1:1.17.1-8) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
(initramfs)

this is a part of /etc/xen/test4.domain.fr.cfg :
----------------------
kernel      = '/boot/vmlinuz-2.6.32-5-xen-686'
ramdisk     = '/boot/initrd.img-2.6.32-5-xen-686'
#kernel      = '/boot/vmlinuz-2.6.26-2-xen-686'
#ramdisk     = '/boot/initrd.img-2.6.26-2-xen-686'


vcpus       = '1'
memory      = '128'

#
#  Disk device(s).
#
root        = '/dev/xvda1 ro'
disk        = [
                
                 'phy:/dev/serveur/test4.gamsau.archi.fr-disk,xvda1,w',
                 'phy:/dev/serveur/test4.gamsau.archi.fr-swap,xvda2,w',
              ]
#root        = '/dev/sda1 ro'
#disk        = [
#                  'phy:/dev/serveur/test4.gamsau.archi.fr-disk,sda1,w',
#                  'phy:/dev/serveur/test4.gamsau.archi.fr-swap,sda2,w',
#              ]
-------------------------------
and it is the same problem with
xm create test4.domain.fr.cfg --dist squeeze
or
xm create test4.domain.fr.cfg --dist lenny

--
but it works when i use '/boot/vmlinuz-2.6.26-2-xen-686'



and old domU lenny are working (with vmlinuz-2.6.26-2-xen-686)
any idea ? suggestion ?

thanks
