A vApp consists of one or more virtual machines that communicate over a network and use resources and services in a deployed environment. A vApp can contain multiple virtual machines.
Starting with vCloud Director 9.5, vApps support IPv6 connectivity. You can assign IPv6 addresses to virtual machines connected to IPv6 networks.
All steps for working with vApps are documented from the card view, assuming that you have more than one virtual data center. Completing the same procedures from the grid view is also possible, but the steps might slightly vary.
