5.4.2.1. OVF Restrictions
Because vCloud Director does not currently support all of the OVF sections supported by vSphere, the following sections of the OVF representation of the vSphere vApp are not carried over to vCloud Director:
AnnotationSection
DeploymentOptionSection
InstallSection
ProductSection
ResourceAllocationSection
All other vSphere OVF properties are parsed by vCloud Director. When a section is ignored by vCloud Director, its contents are not interpreted as they would be by vSphere, and there could be differences in behavior when you instantiate the imported vApp in a virtual datacenter. When a vApp is downloaded from vCloud Director, the OVF descriptor contains only vCloud Director-supported OVF semantics.
