Docker for Mac already can build and run cross-arch containers: https://docs.docker.com/docker-for-mac/multi-arch/

And if you're on x86, you can run ARM containers with QEMU userspace emulation seamlessly after running

    docker run --rm --privileged docker/binfmt:a7996909642ee92942dcd6cff44b9b95f08dad64

The inverse would be extremely easy as well.

Hmm. I would guess then that Docker would be aiming for both emulation and hypervisor. Seems reasonable.

Seamlessly, but with a heavy performance impact. In my experience it's not really usable in anything other than running specific single tests, or some short demos.
