[Xen-users] Kernel Panic - not syncing: Attempted to kill init!

[Fabian Lueghausen <lueghausen@xxxxxxxxxxxxxxxxxx>]

Hello Xen users,

I tried to install Xen 3.1.0 on Scientific Linux (RHEL4), but this mission failed.. Hope you can help me by finding the reason for my problem.
I downloaded the xen sources from http://bits.xensource.com/oss-xen/release/3.1.0/src.tgz/xen-3.1.0-src.tgz and compiled them by running "make" and "./install.sh". This seemed to work.
After setting up grub like this,

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/hda3 console=tty0 console=ttyS0,9600
#          initrd /initrd-version.img
boot=/dev/hda1
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz

 root (hd0,0)
 kernel /vmlinuz-2.6.9-11.EL ro root=LABEL=/ rhgb quiet console=tty0 console=ttyS0,9600
 initrd /initrd-2.6.9-11.EL.img
#
title Xen 3.1 / XenLinux 2.6
 root (hd0,0)
 kernel /xen-3.1.0.gz dom0_mem=256000 noreboot
 module /vmlinuz-2.6.18-xen ro root=LABEL=/ rhgb quiet console=tty0 console=ttyS0,9600
 module /initrd-2.6.18-xen.img

I shut down my machine and restarted it. But it won't come up... as you can see right here:

Is there anyone who has an idea what I'm doing wrong?! Tried it by myself for a few hours, but I'm in the dark...

Thanks for every reply to this email!

Ciao,
