I think this has something to do with Podman, it uses a bit different permissions than normal Docker.

Can you see if it works when you add --privileged to the run command?

I got a little further using the --privileged

I have no idea about the reason to be honest :(

But KVM support for the M1 in Asahi Linux is pretty new and experimental, so maybe its some incompatibility between KVM and the M1 CPU. I only tested this container on Raspberry Pi 4 and 5, and their CPU's have better Linux support.

Also, this container is for Docker, not for Podman. So it is also possible that it is not caused by KVM but by Podman. So you could try if it works in Docker.
