Yeah, it's like WSL. It starts just one VM and then your individual "machines" are LXC containers underneath. If you peek at the vendor-supplied file your NixOS OrbStack Machine includes you can see some of it.

They're constantly doing other optimizations in other ways, too. But that's the one you were pointing at, I think.

That's also what Colima does.

OrbStack isn't open-source though and I can't justify buying a license for every single person in my company just for something functionally equivalent but performing better.

These kinds of things should just be provided by Apple as a first-class thing.
