Re: [Xen-users] How to make an initrd for xen

["John Fairbairn" <webmaster@xxxxxxxxxxxx>]

Just a thought,

did you make sure to add an extra module line to your grub.conf...
example dom0 booting from initrd....

title Xen 2.0 / XenLinux 2.6.11-7
        kernel /boot/xen.gz dom0_mem=256000 console=vga
        module /boot/vmlinuz-2.6.11-xen0 root=/dev/hda2 ro console=tty0
        module /boot/initrd-2.6.11-xen0.img

without the last module line it wont work :)

Hope this helps ya.
