You can use the OVF Authoring options that are included in a virtual machine's vApp options to specify custom information that is included when you export the virtual machine as an OVF template.

vApp properties are a central concept of vApp deployment and self configuration; they can turn a general OVF package into a running vApp instance with a custom configuration.

The set of properties associated to a running vApp is determined by the OVF package from which the vApp was deployed.

When an OVF package is created the author adds the set of properties necessary for the vApp to function in an unknown environment. This could for instance be properties containing network configuration, a property containing the email address of the system administrator or a property containing the number of expected users of the vApp.

Some property values are entered by the user when the vApp is deployed, while other property values are configured by vCenter Server when the vApp is powered on. How this is handled depends on the property type and vCenter Server configuration.

When vCenter Server powers on a vApp, it creates an XML document that contains all properties and their values. This document is made available to each virtual machine in the vApp, and allows the virtual machines to apply the properties to their own environment.

If you want to export a virtual machine as an OVF, you can prespecify product properties. Those properties become available when you deploy the OVF as a virtual machine.

You can manage and define custom properties that are stored in the OVF template when you export a virtual machine or vApp and are used by vCenter Server when you deploy the OVF template. OVF templates support static properties, which are often configured by the user, and dynamic properties, which are always set by vCenter Server.

You can edit the IP allocation policy through the Virtual Machine Properties dialog box.

A virtual machine's OVF settings allow you to customize the OVF environment, OVF transport, and boot behavior after OVF deployment. You can edit and configure settings that affect the OVF environment in the Virtual Machine Properties dialog box.
