I think this is exactly right and is something I have noticed as well. I would also add that this is the reality of the micro kernel model, so in a way tannenbaum was right., micro kernels are the future, but we call them hypervisors.

And with KVM we call hypervisors "Linux"

Which is a very big advantage of KVM, why I like it so much, and worked on it for so long.

But while you are reusing all of the infrastructure from the OS - awesome - you still have two schedulers, two virtual memory subsystems, two IO dispatchers, etc.

Containers, OTOH, are basically the Operating System taking resource isolation one step further, and allowing you to do all that without resorting to all the resource duplication you have with hypervisors - be your hypervisor your own OS or not.

Which of them suits you better, is up to you, your use cases, and personal preferences.
