Re: [Xen-users] Trouble in boot dom0 in xen3.0devel

[Boris Lenzinger <boris.lenzinger@xxxxxxxxx>]

Hi,

When I look at my grub.conf, I see that the initrd passed to xen kernel
is written:
module /path/to/initrd-2.6.11.2-xen0

In your configuration file, I see
initrd /initrd-2.6.11.2-xen0

I think it is your problem. The initrd directive tells to kernel xen.gz
to take this initrd.
Setting module /path/to/initrd-2.6.11.2-xen0 tells to use
initrd-2.6.11.2-xen0 with vmlinuz-2.6.11.2-xen0

Hope this helps.

Boris
