Software-implemented hardware fault-tolerance is on the Xen research roadmap. It basically just requires deterministic execution and event injection. Doing this for uniprocessor guests is fairly straight forward. Doing it for SMP guests (with decent performance) is going to be a huge challenge, as determinism is hard to achieve. We're looking in to it...
