How does this work currently? I was under the impression that Docker for Mac already ran containers in an x86 VM. Probably outdated info, but I’m curious when that changed.
Docker on Mac runs containers in a VM, but the VM is native the cpu architecture and takes advantage of hardware virtualization.
You can of course always use qemu inside that vm to run non-native code (eg x86 on Apple Silicon), however this is perceived as much slower than using Rosetta (instead of qemu).
