The server licensing rights have been expanded, allowing you to install an instance of Essentials on your physical server to run the Hyper-V role (with none of the other roles and features of the Essentials Experience installed), and a second instance of Essentials as a virtual machine (VM) on that same server with all the Essentials Experience roles and features.
