+Unlike [**podman system connection default**](podman-system-connection-default.1.md)
+this option will also make the API socket, if available, forward to the rootful/rootless
+socket in the VM.
+
+## EXAMPLES
+
+To switch the default VM `podman-machine-default` from rootless to rootful:
+
+```
+$ podman machine set --rootful
+```
+
+or more explicitly:
+
+```
+$ podman machine set --rootful=true
+```
+
+To switch the default VM `podman-machine-default` from rootful to rootless:
+```
+$ podman machine set --rootful=false
+```
+
+To switch the VM `myvm` from rootless to rootful:
+```
+$ podman machine set --rootful myvm
+```
