+
+## Setting Podman machine default connection
+
+Each Podman machine exposes two connections:
+
+- rootless
+- rootful
+
+Podman has one default connection.
+
+Podman Desktop, and other tools, such as Kind, connect to the default connection.
+
+After an event that might have changed the default Podman machine connection, such as creating another Podman machine, consider verifying and setting the default connection.
+
+#### Procedure
+
+1. List Podman machine connections, in a terminal:
+
+   ```shell-session
+   $ podman system connection ls
+   ```
+
+1. Set the Podman machine default connection to your desired connection, such as `podman-machine-default-root`, in a terminal:
+
+   ```shell-session
+   $ podman system connection default podman-machine-default-root
+   ```
+
+1. List Podman machine connections, to verify which is the default, in a terminal:
+
+   ```shell-session
+   $ podman system connection ls
+   ```
+
+1. Restart the Podman machine that has the default connection:
+
+   ```shell-session
+   $ podman mahine stop
+   $ podman machine start
+   ```
+
+1. Refresh Podman Desktop connection to Podman: click the **<icon icon="fa-solid fa-lightbulb" size="lg" />** icon to open the **Troubleshooting** page, and click the **Reconnect providers** button.
+
+#### Verification
+
+- Podman Desktop lists images, containers, and pods that are accessible via the desired Podman machine connection.
