A VM Class predefines hardware for Supervisor-managed VMs: "The VM class... defines such parameters as the number of virtual CPUs, memory capacity, and reservation settings." Administration steps show these are configurable: "You can configure hardware resources such as CPU, memory, and different devices" when editing a VM class. Additionally, the DCLI/API specification underscores CPU and Memory fields: "--cpu-count ... Required." and "--memory- mb ... Required." for a VM class. While network adapters, PCI devices, and instance storage can also be added via advanced config, the question asks for two; CPU and Memory are canonical, always-present VM Class resources per the core definition above.
