Hi

I am trying to install the latest version
of xen (xen-4.0.1 rc3) on Ubuntu 10.4 and amd 64 processor. But I am
getting errors to boot dom0 kernel. I am using the steps given 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/




The error I am getting is also reported on the XEN mailing list below.

Can anyone tell me what I am doing wrong?

Boot from the Ubuntu install iso in recovery mode "Rescue a broken system", choose to "execute a shell in your root partition", then verify your root's device number (hd0,2) etc... and take a look at the generated menu.cfg. 

Also, increase the timeout in /etc/default/grub so you get a boot menu, and re-run update-grub. (Note that if you have multiple partiitons you'll need to run 'mount -a' after getting the recovery shell.

If it's using UUIDs, try changing to device names instead. You can change this in etc/default/grub as well.

If you can get a grub menu up, at from there you manually tweak the boot params until you get something that works.
