There are a number of ways of thinking about this:
* if you want to help out with KVM development and testing, using the
latest released kvm.ko with your currently installed kernel might be
a good idea. If you want to get really hard-core, use Avi's kernel
git tree.
* if you just want some KVM feature that isn't in your currently
installed kernel, the latest released kvm.ko might make sense.
* if your main concern is stability, use an unmodified kernel release
and stable updates - e.g. 2.6.27.x or 2.6.28.x
Which version of kvm-userspace/qemu you use is a very different story -
unless you have a very old kernel version, just use the latest release
kvm/qemu release.
Cheers,
Mark.
