Hi,
Could you try following and check

title Xen 2.0 / XenLinux 2.6
  kernel (hd0,0)/xen-2.0.gz dom0_mem=131072
  module (hd0,0)/vmlinuz-2.6-xen0 root=/dev/hda3 ro console=tty0

Regards,
Sharath

I am installing Xen on a remote server.  I left the other kernels on the grub.conf and made xen the default to boot from.  The box didn't boot into Xen on reboot but I'm not sure why.  Here is my Xen config file:

# grub.conf generated by anaconda

# Note that you do not have to rerun grub after making changes to this file

This is a CentOS 4.1 box.  What did I do wrong?
Thank you.
