Managing vApps


In order to group virtual machines into a logical group, XenServer 6 has introduced a new feature named vApp. A vApp is a logical group of one or more VMs which can be started up as a single entity.

When a vApp is started, the VMs contained within the vApp will start in a user predefined order, to allow VMs which depend upon one another to be automatically started.

You can create, modify, and manage vApps using Manage vApps available in the Pool menu in XenCenter. When you select a vApp in the list, the VMs it contains are listed in the details pane on the right.
