Option Description
DHCP A DHCP server is used to allocate the IP addresses. The addresses assigned by
the DHCP server are visible in the OVF environments of virtual machines started
in the vApp.
Static - IP Pool IP addresses are automatically allocated from the managed IP network range of
vCenter Server at power-on, and remain allocated at power-off.
Static - IP Pool and Transient - IP Pool have in common that IP allocation is done through the range
managed by the vSphere platform as specified by the IP pool range in a network protocol profile. The
difference is that for a static IP Pool, the IP addresses are allocated at first power-on and remain
allocated, while for a transient IP Pool, the IP addresses are allocated when needed, typically at
power-on, but released during power-off.
Edit OVF Authoring Options for a Virtual Machine
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.
n
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.
n
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.
1 Edit vApp Product Information for a Virtual Machine in the vSphere Web Client
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.
2 Manage vApp Custom Properties for a Virtual Machine in the vSphere Web Client
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.
3 Edit vApp IP Allocation Policy for a Virtual Machine in the vSphere Web Client
You can edit the IP allocation policy through the Virtual Machine Properties dialog box.
