With the other work now mostly done, sure, let's pick this up again. I think next on the list was getting the virtio rng device delivering VM clone events and unique UUIDs. There was a spec change posted a while back and a patch for the kernel. Do you want to refresh those? I thought that was a promising direction -- and the one we all decided together in person as the most viable, race-free way, etc -- especially because it would make ways of exposing those IDs low cost. And, importantly for you, I think that might *also* cover the need that you have here, so we'll kill several birds with one stone. Jason
