[Xen-users] booting XEN from softwareraid /dev/md0

["Mike Mildner" <m.mildner@xxxxxxxxxxxxxxxxxxx>]

hi folks,


i'm a xen newbie - but quit good in linux.
i have not a classical distribution,i use CLFS-Multilib x86/64
xen-3.3.1 from source with gcc-4.2.2

on my system i run a mdadm managed software raid  and this contains a reiserfs.
the standard kernel boots without problems from /dev/md0
but the xen kernel gives a PANIC while trying to mount the root-fs. (see bottom)
in the xen-kernel self, i compiled RAID1(mirroring) and reiserfs staticly. in 
my grub/menu.lst:
kernel /boot/xen-3.3.1.gz noreboot dom0_mem=400000
module /boot/vmlinuz-2.6.18.8-xen ro root=/dev/md0 console=tty0 vga=791
root (hd0,0)

the last lines from failed booting:
md: Autodetecting RAID array
md: autorun...
md: ...autorun DONE
ReiserFS: md0: warning sh-2006: read_super_block: bread failed (dev md0, 
block2, size 4096)
ReiserFS: md0: warning sh-2006: read_super_block: bread failed (dev md0, 
block2, size 4096)
No Filesystem could mount root, tried: reiserfs ext3 ext2 iso9660
Kernel Panic - not syncing: VFS: unable to mount root fs on unknown bblock (9,0)

whats is my error?
