VM

After installation, you must start a VM:

podman machine init --cpus 4 --now

Then run the suggested "podman-mac-helper" commands to allow Podman to use the default Docker API socket.

To stop and remove it afterwards:

podman machine stop

podman machine rm

The default machine name is "podman-machine-default".

The extracted VM image is stored (on a Mac) at:

~/.local/share/containers/podman/machine/applehv/<machine name>-arm64.raw

The Docker images registry for the Podman machine. For example, use an older one:

podman machine init --image docker://quay.io/podman/machine-os:5.0 --cpus 4 --now 

How to check the version of the Podman machine:

podman machine ssh
...
rpm-ostree status

(Shows the version.)

Mac: Uses Apple's virtualization

Hypervisor

https://github.com/crc-org/vfkit/blob/main/doc/usage.md

vfkit is the process that runs the VM. The VM terminates when the process exits.
