There is no dependency of the dom0 and domU kernel versions.
Just place your vmlinuz-2.4.*-xenU in the /boot dir of your
domain0 then you can reference it in your domain config file
like this:

kernel = "/boot/vmlinuz-2.4.29-xenU"

Hi

Thanks for the reply.

The problem is that FC4 doesn't come with a 2.4 xenU kernel.
Is there a way I can build one?

Many thanks
Shaz

you can build one with at least the 2.06 stable sources.

Just Append "linux-2.4-xenU" to "KERNELS ?=" in the Makefile of XEN and run
make kernels or
make install

The Kernel sources will automatically be downloaded. You can configure your
Kernel in the directory linux-2.4.* with

make ARCH=xen menuconfig

and do another

make install

Hi

Great thanks.

What I did was to download the 2.06 kernel. It has the 2.4 kernel in there.
Question:
Do I need to boot into a 2.4 xen0 kernel to run 2.4 kernel in domU's,
or can I run 2.4kernel domU while running a 2.6 Dom0 kernel.

Basically I'm getting my head round this idea.

In any case I tried to reboot into the 2.06 xen kernel on my sony vaio
but after loading some xen messages the system just reboots with out
loading: here's my grub.conf file:

title Xen (2.4.30-xenU)
root (hd0,1)
kernel /boot/xen.gz dom0_mem=150000
module /boot/vmlinuz-2.4.30-xen0 ro root=LABEL=/

Any ideas about this?

Thanks
Shaz

Yuo can run a 2.4 domU with a 2.6 dom0. For that matter, you could run a
FreeBSD, NetBSD or Plan9 domU too. The virtual device interface is OS
independent.

You can't boot with LABEL= syntax unless you use an initrd. Yu cuold make a
new initrd (do "man mkinitrd" for more info) or you could just specify the
partition you boot off (e.g. probably /dev/hda1 in your case).

Cheers,
Mark
