Re: [Xen-users] Re: [Xen-devel] What is the implication to use 'module'directive instead of 'initrd' to load ramdis

["Edney Matias" <edneymatias@xxxxxxxxx>]

Hi,

what Jan is trying to say is that, since the dom0 kernel needs an
intrd image and since these options are passed to Xen kernel as
modules directives, you´ll need to specify them  as modules in your
grub.

title Xen Unstable /Red Hat Enterprise Linux 2.6.16.33
kernel /xen.gz console=vga <- Xen kernel
module /vmlinuz-2.6-xen  <- dom0 kernel passed as a Xen module
module initrd /initrd-2.6.16.33-xen.img <- dom0 initrd file passed as
a Xen module

Regards!

Matias
