Podman Virtual Machine

Podman on MacOS or Windows requires a virtual machine. This is because containers must run with a Linux kernel, and the podman virtual machine provides that Linux kernel on Mac. If it does not exist, the virtual machine must be initialized, then started.

The started virtual machine mounts as volume the home directory of the user that starts it. There's also an API server listening on $HOME/.local/share/containers/podman/machine/podman-machine-default/podman.sock.

A started virtual machine survives reboot.
