To review the configuration for a VM that is running, simply open the VM configuration editor and click the expansion symbol for the features you wish to review. (The VM configuration wizard can only be used for creating new VM configuration files, not for reviewing or modifying existing files.)
You can also view configuration files using any text editor. However, you will see different information if you display the file using a file editor than if you use the VM configuration editor.
You should not edit the VM configuration file directly. You should only modify a configuration by using the VM configuration editor.
