(1) It looks like you are manually trying to install the the domU.
Have you tried using the Yast2 Virtual Machine Manager to do the domU
(2) It looks like the paths to your kernel and initrd are incorrect.
If you use the Yast2 Virtual Machine Manager it will give the right

One explanation for why your 10.3 install is not working is because
the 10.3 network boot cd (73MB) does not have a Xen Kernel.

I have tried installing 10.3 as a guest of 10.2 and was also
unsuccessful. So this confirms that someone has had the same
experience but I have not been able to fix this.

Has anyone successfully installed a 10.3 domU in a 10.2 dom0?

Another possible explanation for why a 10.3 domU does not work in a
10.2 dom0 is that the kernel is xen aware and since the 10.2 kernel is
older than the 10.3 kernel, 10.2 is not aware of how to host 10.3 as a
guest/domU. It may be possible to install 10.3 as a guest of 10.2 but
you would probably have to do it much like installing a completely
different OS such as Centos, or RedHat. in otherwords you must install
10.3 as a guest OS that is not xen aware.  Im speculating here (based
on my limited understanding of opensuse and xen documentation ive
read), so more educated opinions are welcome.

I resorted to installing 10.3 as Dom0 and 10.2 as a  DomU and this
works. 10.3 is much nicer since it has a paravirtualized graphics
adapter so you can do a graphical install and have graphical access to
your machine without having to setup VNC on your own.

In your case and in my case (since the hard disk for my 10.2 system is
lying around), if it is not possible to erase your 10.2 system  it
would be helpful to determine how to take an existing 10.2 filesystem
(ext3), convert that into a  "Sparse Image File", and use the "Sparse
Image File" to boot my old 10.2 system. Is this possible? Anyone know
how to do this?
