No hardware virtualization 😢

Don't think this is linked to qemu brew pkg https://github.com/crazy-max/ghaction-setup-docker/actions/runs/7753530253/job/21145026329?pr=53#step:3:80 being installed along lima?

Nested virt is still missing on ARM macOS 😞

Thanks for looking into this! It would be great to be able to run arm64 Docker on GHA.

I guess we are waiting for Apple to add support for nested virt.

While not a long term solution, does qemu support virtualization without hardware assistance?

Per https://apple.stackexchange.com/a/473306/21181 macOS 15.0 supports nested virtualization. Does that mean that it should be possible to support Docker in GitHub macOS runners?
