This one should work:-

menuentry "Xen 4 / Ubuntu 10.04 kernel 2.6.32.15" {
insmod ext2
set root='(hd2,2)'
multiboot (hd2,2)/boot/xen.gz dummy=dummy
module (hd2,2)/boot/vmlinuz-2.6.32.15-xenpci dummy=dummy nopat root=/dev/sdc2 ro console=tty0
module (hd2,2)/boot/initrd.img-2.6.32.15-xenpci
}

My current env :-
menuentry "Xen 4.0 / Ubuntu 10.04 kernel 2.6.32.15" {
insmod ext2
set root='(hd0,9)'
multiboot (hd0,9)/boot/xen.gz dummy=dummy
module (hd0,9)/boot/vmlinuz-2.6.32.15 dummy=dummy nopat root=/dev/sda9 ro console=tty0
module (hd0,9)/boot/initrd.img-2.6.32.15
}

Hey all,

I tried to install xen 4.0.1-rc3pre on my ubuntu installation. The
installation seemed to work. I also compiled my own dom0 kernel
(2.6.32.15). The kernel works perfect when i boot it without xen.
However, when i want to start the xen hypervisor i get the following
error from grub: "Error: couldn't open file", followed by some lines
that say that the multiboot kernel should be loaded first.

This is my menu entry:
menuentry "Xen 4 / Ubuntu 10.04 kernel 2.6.32.15" {
insmod ext2
set root='(hd2,2)'
multiboot (hd2,2)/boot/xen.gz /boot/xen.gz
module (hd2,2)/boot/vmlinuz-2.6.32.15-xenpci dummy=dummy nopat
root=/dev/sdc2 ro console=tty0 ro console=tty0
module (hd2,2)/boot/initrd.img-2.6.32.15-xenpci
}

I'm pretty sure that hd2,2 is correct as booting the linux kernel with
that drive as root works. I also tried without the /boot but that
didn't help. Does anyone have an idea what causes this problem?

Thanks
Thomas Richard
