Friendly ping again. We would really like to have a constructive technical conversation and collaboration on how to make forward progress with VM clone notifications for user space applications that hold unique data and hence need to learn about VM clone events, outside of any randomness semantics.
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.
