Another thought is that if you have the option to reinstall the dom0, use lvm for dom0's /. That works.

Try 4 instead of 5, there was a change in the 0/1 base for grub's device numbers.

my grub entry is

module    (hd0,5)/boot/initrd.img-2.6.18.8-xen0
}

in /boot/grub/grub.cfg I have the following entry for default boot with ubuntu 10.04.

menuentry 'Ubuntu, with Linux 2.6.32-23-generic' --class ubuntu --class gnu-linux --class gnu --class os {

    insmod ext2

    initrd    /boot/initrd.img-2.6.32-23-generic
}

I have tried root as UUID as well but it given me the same boot error of not finding root.

My disk partitioning is as follow

df -h

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.

http://lists.xensource.com/archives/html/xen-users/2010-06/msg00759.html.









Can anyone tell me what I am doing wrong?

Thanks
