In the navigation pane on the left, navigate to vCloud Air Services.


Click Cloud Instances and select the cloud instance that contains the virtual data center.


In the Related Objects tab, click the Virtual Data Centers tab.


Right-click the virtual data center you want to edit and select Edit Settings.


Change the resource allocation and click OK.

You can view the resources available in the cloud instance that are not yet allocated to any virtual data center.
