Or, RTFM. As the lvs howto states at :
http://www.linuxvirtualserver.org/Joseph.Mack/HOWTO/LVS-HOWTO.unsupported
html#id2894179
there is a working procedure for compiling lvs module with the redhat kernel
read the INSTALL file here :
http://mail.incredimail.com/howto/lvs/install/INSTALL
this works for i386 arch, you could try and tell us if it works for you on
s390, maybe even provide me with the compiled binaries for other people to
use. Remember, a negative result is also a positive thing ;)
Alex.

If you have a version of ipvsadm that works at all, the version of the
kernel code can be displayed using "ipvsadm -L -n" and the version of
ipvsadm and the kernel code it was compiled against can be shown using
"ipvsadm -v".
It seems that Red Hat, in their infinite wizdom, ship 7.2
a kernel with ipvs patched in, but no matching version of ipvsadm.
Persumably this comes with some souped up version of 7.2 that uses
the same kernel. Still, its pretty lame.
In inspecting linux-2.4.2-ipvs.patch in their kernel source package
I find the line:
IP_VS_VERSION_CODE 0x000207
Indicating version 0.2.7. I'll stand corrected, but AFIK there is
no version 0.2.7 of LVS. So this must be a custom version. I don't
have the time or inclination to hunt through their sources
to find what version of ipvs this is based on. But suffice to
say there isn't a version of ipvsadm available on linuvirtualserver.org
that matches this.
You might get some value out of getting the source for the latest
ipvsadm and removing the version check. It really depends
on what changes Red Hat have made to what version.

The suggestion that I have made above is probably worth a try, failing
that you are probably best to bite the bullet and build your own kernel.
Here are a couple of options that you have with regards to that:
1. Use the kernel supplied with Ultra Monkey 2.0.0. This is
the Red Hat 7.2 kernel with their lvs code removed and
1.0.4 added in.
You also need to get the separate ipvs package. Which
has the ipvs modules. Actually, do to some issues in
the building of this package, i would suggest installing
the kernel and herken-headers package and rebuilding
the ipvs package.
2. Take Red Hat's RPM, remove their lvs stuff. Backport the new
lvs code. And make a compatibility patch to fix things that
break in the process. Make your own RPM.
3. Start from scratch and patch and build your own kernel based
on the one from linux.org. This is the only method that is
likely to get support from this list.
