Re: [Xen-users] Re: [Xen-devel] What is the implication to use 'module'd
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!

Jan,
I used SINGLE module to load kernel and SINGLE intird to load ramdisk in
grub.conf file.
title Xen Unstable /Red Hat Enterprise Linux 2.6.16.33
kernel /xen.gz console=vga
module /vmlinuz-2.6-xen ro root=/dev/VolGroup00/LogVol00 rhgb quiet
console=tty0
initrd /initrd-2.6.16.33-xen.img
Based on what you explained, this should be fine. However, Xen Linux still
got a panic message: Linux kernel must be loaded before ramdisk.
How do you explain this?
Thanks,
Liang
