 Podman uses this value to do extra setup around networking from the
 container inside the VM to to host.
 
+**machine_host_type**=""
+
+Indicates the type of machine if Podman is running inside a podman machine
+instance. The value is only relevant if machine_enabled is true. The default
+value (empty string) indicates the machine host type is unknown.
+
 **multi_image_archive**=false
 
 Allows for creating archives (e.g., tarballs) with more than one image. Some container engines, such as Podman, interpret additional arguments as tags for one image and hence do not store more than one image. The default behavior can be altered with this option.
