I think I understand what you're trying to say, but here's what I have.  I have the following RPMS installed:
The first file provides the actual prebuilt images, the second provides the source code, patched with XEN.  I'm not trying to change configurations or architectures from the XEN architecture or the default XEN configuration.  I'm just trying to build the default XEN image and I'm getting these errors.
The XEN 3 images that I've had stability issues with are both the default SuSE ones and the ones provided by Kurt Garloff - neither seem to provide a stable operating environment for me.

I didn't explain myself very well.

There are 'source' RPM's and 'binary' RPM's.

I believe you are trying to build a xen kernel from the source tree that
comes with the kernel-source-{,}.i586.rpm
'binary' RPM. That does not work. That source tree is just for building
the kernel-default-{,}.i586.rpm 'binary' RPM.

In an ideal world you would be able to build all the different kernel
architecture from the source one tree, but in practice that is not the case.

Instead you have to start with the 'source' RPM
( kernel-source-{version}.src.rpm ), using the appropriate spec file
for the architecture you want to build (i386 xen in your case?).


If you look at your installation media (CDROM, DVD, FTP mirror site)
there is a binary RPM in ./suse/i586/kernel-source-

That RPM is a 'binary' RPM, that happens to contain just the kernel
sources. Specifically these are kernel sources that were used to build
the kernel-default- 'binary' RPM

Note how these RPM's both end in '.i586.rpm'.

Both these binary RPM's were created from a 'source' RPM found in

This source RPM contains kernel.org kernel, plus architecture
specific patches (xen, uml, ppc, s390, itanic), plus architecture
independant fixes, plus build instructions (spec files, scripts,

This is all described in much more detail and more accurately than I
have done in the documentation found in

One thing that the above documentation file does not mention is
that kernel-source-{version}.src.rpm file alone is not sufficient.
You also need a kernel-source-{arch}-{version}.nosrc.rpm file too.
(except when you are building the kernel-default).

If you want to build the kernel-xen- binary RPM,
you need to fetch:



Read up on 'man rpm' and 'man rpmbuild' for installing and building
RPM files.

It will be difficult to build because that is now gone
from the suse site and its mirrors.

If you want to use a SuSE kernel and xen 3.0, then you will have to
use the source RPM's (or binaries) that Kurt Garloff distibutes.
His page is

and follow the link that reads 'SUSE Linux 10.0 RPMs'
I haven't tried running a SuSE 10.0 kernel with a SuSE 9.3 install
though. It may work.

Alternatively, you could use the kernel source that comes from the
xensource.com or www.cl.cam.ac.uk sites. That might be much less effort
too. You only really need to bother with the SuSE sources if you
want a kernel that is as close as possible to something that SuSE ships.
