TIDM onap.capabilities.Compute

This capability characterizes a virtual machine. Intended to be used primarily as part of a TOSCA requirement clause. Normally, requirements of this type are never satisfied within the model. They stay “dangling” until instantiation. On instantiation, the orchestrator satisfies them out of the available inventory.
