I will say though, my experience with nested virt is that it's not especially stable unless you control all three kernels (host, guest, nested guest). I've personally seen upgrades of a kernel at one layer introduce instabilities requiring upgrading the other layers. Also the usual failure mode for this is the middle layer spontaneously going away, so if you're not also the service provider, you have little if any insight into the actual problem. -- Jeremy Stanley
