Owen,

"Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-bloc=
k(1,0)" i think means that=20
your kernel cannot find or mount a (temporary) root filesystem on a devic=
e with major 1 and minor 0.
There is only 1 device like that, and it's the ramdisk.

So your kernel cannot mount the filesystem in your initrd.
Did you create the initrd (and ftp to the domU) as intructed ?
Did the creation of this initrd (with the mkinitrd command) give you any =
errors ?

An error that i saw again and again is that at the moment the initrd is c=
reated, no loop drivers are loaded.
The mkinitrd command does not seem to load this module automatically,
so, on your dom0, do a "modprobe loop" and recreate the initrd and ftp it=
 again.

If that doesn't work, maybe you could mount the initrd on dom0 and have a=
 look inside ?

Greetings,
Sven

Subject: [SSI-users] Xen and OpenSSI


Hi All,
I'm trying to get OpenSSI working on Xen and have hit a problem.
I'm following the instructions at http://openssi.org/cgi-bin/view?page=3D=
docs2/1.9/debian/xen-howto.txt and also the document at http://www.option=
-c.com/xwiki/OpenSSI=20
I've got as far as booting the domU with the OpenSSI kernel and I get "Ke=
rnel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1=
,0)"
My base Xen installation is 2.07 on Debian Sarge using the packages from =
option-c and I used the pre-built OpenSSI kernel.
My config file for the domU is:
#kernel =3D "/boot/xen-linux-2.6.11-ocxenu"
kernel =3D "......./xenU-vmlinuz"
ramdisk =3D "........./initrd"
memory =3D 64
name =3D "<hostname>"
disk =3D ['file........img,hda1,w','file.........img,hda2,w']
root =3D "/dev/hda1 ro"
#
vif =3D ['mac=3DAA:00:00:18:94:FB']
and /etc/fstab on the domU is
# Begin /etc/fstab
# <file system> <mount point>   <type>  <options>                        =
  =20
/dev/hda1       /       ext3    defaults,errors=3Dremount-ro,node=3D1    =
   0
/dev/hda2       swap    swap    sw,node=3D1       0       0
proc    /proc   proc    defaults,node=3D* 0       0
# End /etc/fstab
Does anyone have any ideas as to where I've gone wrong?
