-  - If more than one server with the name given by the C(name) option exists, execution is aborted.
+  - If I(uuid) option is provided, it takes precedence over I(name) for server selection. This allows to update the server's name.
-  - Once a server is created all parameters except C(state) are read-only. You can't change the name, flavor or any other property. This is a limitation
