> Containerization executes each Linux container inside of its own lightweight virtual machine.

That’s an interesting difference from other Mac container systems. Also (more obvious) use Rosetta 2.

Podman Desktop, and probably other Linux-containers on macOS tools, can already create multiple VMs, each hosting a subset of the containers you run on your Mac.

What seems to be different here, is that a VM per each container is the default, if not only, configuration. And that instead of mapping ports to containers (which was always a mistake in my opinion), it creates an externally routed interface per machine, similar to how it would work if you'd use macvlan as your network driver in Docker.

Both of those defaults should remove some sharp edges from the current Linux-containers on macOS workflows.
