Hello everyone,

I'm quite a newbie with Xen and I'm currently having an issue.
I run Xen 4 on Debian Squeeze x64 and I'm trying to build an OpenFiler DomU 
from the Xen domU filesystem tarbal they provide (See 

I downloaded the tarball and run 'tar xzpvf 
/root/soft/openfiler-2.3-x86_64.tar.gz' to extract the files to the lvm.

My config file is:

bootloader = '/usr/bin/pygrub'
vcpus       = '1'
memory      = '512'
root        = '/dev/xvda1 ro'
disk        = [
name        = 'openfiler'
vif         = [ 'ip=,mac=00:16:3E:C4:D8:AC' ]
#vfb        = [ "type=vnc,vncunused=1,keymap=fr" ]
extra       = 'console=hcv0 xencons=tty0'
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

When I create this domain and attach the console, I get the Grub menu and but 
soon after it crashes. Here is the console output:

Kernel panic - not syncing: Attempted to kill init!

The /etc/inittab on the domU shows:

Any idea on how I could fix the problem ?

Many thanks in advance.
