I've been compiling it for OpenSuSE 10.3 (and 11.0 recently) with only 
minor effort since kvm-65 or earlier. My method should work as-is for 
SLE 10 versions. This message may be a bit long and OT for the list but 
I'll take the heat and maybe someone can help me understand why the 
second part of the patch is needed for me. If you have any questions 
that require much discussion maybe we can take it off-list.

Procedure (kvm-70 and later):

Make sure you have the kernel source and C/C++ development pattern 
installed.

# cd /usr/src/linux
# make cloneconfig
# make modules-prepare

Download the kvm source tarball
Explode it somewhere
# cd kvm-<version>
# ./configure

Patch kernel/Makefile as follows, the first change can be avoided easily 
but it's easier to just patch the Makefile as shown. The second change 
really seems necessary on my SuSE platforms. Be careful to consider if 
my or your mail client word wraps the patch (I pasted it as plain text). 
The patch just replaces the relative path to the kernel source with a 
literal path that works on OpenSuSE 10.3/11.0 and adds the kernel 
source's linux/include as a higher priority include path than the kvm 
include-compat.

OpenSuSE 10.3 and 11.0 include kvm modules and qemu. I delete all the 
kvm stuff under /lib/modules/<current kernel> before the install.

To get the kvm drivers to load at boot time add the kvm.ko and 
kvm-<platform>.ko module to the INITRD_MODULES section of 
/etc/sysconfig/kernel and run mkinitrd. modprobe or insmod the drivers 
to start right away or reboot the host to load them from the ramdisk.

When you update the kernel you may as well repeat the process from the top.

The qemu executable is qemu-system-x86_64 and has been working really 
well for me.
