UTM also have their own docs on it:

And FYI, this is also available in Docker Desktop for macOS, which allows better performance when running x86_64 containers compared to the older solution where Docker was using qemu.

Do you have any sources for that? I basically gave up on Docker for M1 since the qemu performance is terrible.

Last time I checked, Rosetta only worked for one-off binaries, wouldn’t really allow docker to run more x86 code inside.

It is used for individual binaries. The Linux kernel is arm, but the binaries running on it can be x86 running on Rosetta. This works particularly well with containers, which come with their own libc.

I'm not sure what you're asking here?

Rosetta is a tool for running x86-64 binaries on an arm64 OS.

I think you're asking if rosetta lets you run an x86 kernel, to which the answer is no - the whole point of this framework is to support virtualization, e.g. the OS is running directly on the hardware. The moment the OS can't do that, there is no point in doing anything other than emulation.

Yes, I've used it with Terraform plugins by setting the arch to x86 and running via docker. Needed to do this as some plugins don't have arm64 versions.
