1. I would suggest you to obtain a serial log and escalate the problem to xen-devel.
2. Could you post yours /usr/src/linux-2.6-xen/.config ( gzipped) ,/boot/grub/grub.cfg,
"df -h" output.

Boris.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64 bit version using the tutorial at 

http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/ on a Lenovo thinkcentre workstation.

When I boot I get a kernel panic. If I boot the Linux kernel that I compiled using the tutorial on it's own it boots fine. 

Is the likely cause hardware? is there a common error made in this tutorial that would cause a panic on boot. 

Murray
