[Xen-users] problem booting xen 3.0 dom0 on

[Jayesh Salvi <jayeshsalvi@xxxxxxxxx>]

Hi,

I am installing Xen 3.0 on a Ubuntu system. I am having trouble making the GRUB boot with the Xen dom0 image I built. I am using the initramdisk created by commands:
# depmod 2.6.12.6-xen0
# mkinitramfs -o 
initrd-2.6.12.6-xen0.img 2.6.12.6-xen0

Grub version: GNU GRUB  version 0.95
--------------------------------------------------------------------------------------------------------------------------------------------------------------
The title paragraphs from menu.lst - first for regular Ubuntu kernel and second for Xen.

title           Ubuntu, kernel 2.6.12-9-686

initrd          /boot/initrd.img-2.6.12-9-686
savedefault
boot

boot

When I boot Xen 3.0/XenLinux 2.6, I get the  following message:
--------------------------------------------------------------------------------------------------------------------------------------------------------------
 Booting 'Xen 3.0 / XenLinux 2.6'

I don't understand what is wrong with my grub entry for Xen. 
xen-3.0.0.gz is a multi-boot kernel. I built it from the Xen 3.0 source code. 

I also don't understand the exact difference in giving the vmlinuz* image as a kernel as in first paragraph, versus giving it as a module as in Xen paragraph.

Can anyone tell me what can I try?

Thanks
