Re: [Xen-users] installing xen 4.0.1 rc 3 on ubuntu 10.04 grub 2 errors

Try this hacked version of /etc/grub.d/10_linux. Save your grub.cfg, then copy it onto your system and run update-grub. It works for me, but I'm using lvm partitions to the device addressing is different.

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.

Try removing the leading (hd0,5) from the multiboot/module lines.

my grub entry is

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 {

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
