If you just switch the binary you’re 90% finished but there are some chores to make it perfect
1. The arguments given to the qemu should be changed by the CPU arch. For example, AArch64 uses ‘-accel=hvf’ while amd64 in Apple Silicon must use ‘-accel=tcg’. AArch64 requires ‘-cpu’ option whild amd64 does not. etc. And currently, the arguments of QEMU is half-way hardcoded to the podman source code.
2. You should change the linux image when you change the CPU arch. Currently, podman always downloads the Linux image whose CPU arch is same with host’s CPU arch. This is where configuration should be added.
3. aarch64 uses UEFI while amd64 don’t need to (I don’t know why)
