Over the weekend the latest kvm kernel module was released based on the 2.6.32-rc7 kernel. The kvm-kmod provide the kernel module only and can be used to upgrade an older kernel with recent kvm kernel module features without having to upgrade your kernel. All you need to do is compile against your current kernel to include the latest kvm kernel features that your kernel can support. For more information on how you can use the git repository of the kvm-kmod to check out kernel trees see the following link.
