Table Of Contents
n
Zero or more SourcedItem elements, each of which defines a source of virtual machines to include in the
composition. Each SourcedItem must contain a Source element that references a composition source, the
href of a Vm, VApp, or VAppTemplate. If the Source element references a virtual machine, the SourcedItem
can include any of the following elements:
n
An InstantiationParams element specific to that virtual machine. This element can include any of the
section types listed under “Configuring a Virtual Machine,” on page 87.
n
A NetworkAssignment element that specifies how the network connections in the virtual machine are
mapped to vApp networks defined in the InstantiationParams element that applies to the composed
vApp.
n
A VAppScopedLocalId element that provides a unique identifier for the virtual machine in the scope
of the composed vApp.
If the Source element references a vApp or vApp template, all Vm elements from each composition source
become peers in the Children collection of the composed vApp.
n
If any of the composition items is subject to a EULA, the ComposeVAppParams element must include an
AllEULAsAccepted element that has a value of true, indicating that you accept the EULA. Otherwise,
composition fails.
The composed vApp must be deployed and powered on before you can use it.
Prerequisites
Verify that you are logged in as a system administrator or member of an organization in the cloud.
Procedure
1 Find the composeVApp link in the target vDC.
The XML representation of the vDC contains a composeVapp link, which has the following form:
<Link
rel="add"
type="application/vnd.vmware.vcloud.composeVAppParams+xml"
href="https://vcloud.example.com/api/vdc/5/action/composeVApp" />
2 Create a ComposeVappParams element that specifies the details of the composition.
3 POST the ComposeVappParams element to the composeVapp link of the target vDC.
See the Request portion of “Example: Compose a vApp,” on page 81.
Example: Compose a vApp
This request specifies two vAppTemplate items and one Vm item. The Vm item requires InstantiationParams that
modify its NetworkConnectionSection to specify the vApp network created for this vApp. The vAppTemplate
items inherit this setting from the base InstantiationParams element that appears before the first
SourcedItem is specified.
NOTE Virtual machines specified in Source elements must be powered off or this operation will fail. You can
use a query like this one to return a list of references to powered-off virtual machines that you have access to.
