It can be useful to create Properties at the Business Group level in vRA. One possible use case is to act as flags for decisions made by vRO. I will show an example of this and a hypothetical use case.
Using a vc:virtualmachine object, retrieve ESXi host and vCenter Cluster objects. Most of the other attributes are easy to find in the API explorer, but these two are ‘hidden’ in the ‘runtime’ attribute.
