Oracle VM Manager allows you to drag and drop Oracle VM Servers and virtual machines to and from server pools, the Unassigned Servers folder and the Unassigned Virtual Machines folder in the navigation tree. You can drag and drop Oracle VM Servers from the servers table in the management pane to a server pool or the Unassigned Servers folder in the navigation tree. You can also drag and drop virtual machines from the virtual machines table in the management pane to an Oracle VM Server or to the Unassigned Virtual Machines folder in the navigation tree. If you drag and drop an Oracle VM Server or virtual machine to an invalid destination an error message is displayed.
