For a vApp and its associated virtual machines to have connectivity outside the vApp, the virtual machines must be connected to an internal or external organization network. Available organization networks are usually created and defined by an organization administrator. When the vApp is deployed, it is automatically attached to the organization network defined when it was created and uploaded to the catalog. It is also possible for the user to select which network to connect to the virtual machine.

A vApp deployed from a published catalog created in a different organization might have a different or invalid network defined, in which case the user should select a valid organization network and attach the vApp.
