Details
There is no integrated functionality in RHV that allows you to deploy a multi-vm construct from a single template (like e.g. with vSphere vApp or VMM Service Templates).

Comment: CloudForms (fee based cloud offering) has components called Deployable - defined as an Application deployment definition that contains one or more assemblies and meta-data configuration; this configuration specializes a deployment by qualifying it for a specific targeted infrastructure. A Deployable is essentially made of one or more Assemblies with configuration data. Each Assembly is made of one or more Templates and configuration. Each Template lists the software and configuration data. An Assembly optionally indicates the services that it defines or requires. Some of the configuration data may be defined a the time of instance launch.
