I would assume that "lightweight" in this case means that they share a single Linux kernel. Or that there is an emulation layer that maps the Linux Kernel API to macOS. In any case, I don't think that they are running a Linux kernel per container.

You don’t have to assume, the docs in the repo tell you that it does run a Linux kernel in each VM. It’s one container per VM.

Good call, thanks for clarifying!

"Lightweight" in the sense that the VM contains one static executable that runs the container, and not a full fledged Ubuntu VM (e.g. Colima).
