Managing vApps

June 25, 2018

A XenServer vApp is a logical group of one or more related virtual machines (VMs) which can be managed as a single entity. The VMs within a vApp do not have to reside on one host server and will be distributed within a pool using the normal rules.

When a vApp is started, the VMs contained within it will start in a user-defined order, allowing VMs which depend upon one another to be automatically sequenced. This means that you do not need to manually sequence the startup of dependent VMs should a whole service require restarting, for instance in the case of a software update.

Using the Manage vApps dialog box

Use the XenCenter Manage vApps dialog box you can create, delete and modify vApps, start and shutdown vApps, and import and export vApps within the selected pool. When you select a vApp in the list, the VMs it contains are listed in the details pane on the right.
