I'm not sure what you're talking about. That's how hyperv has always been deployed. Install Microsoft server, install hyperv role. It's a hypervisor. Does all the fancy things like clustering as well, through the fail over cluster manager where you can view all your hosts, move vms from host to host, configure your witnesses etc. It absolutely is a competitor in the esxi space, never had quite all the bells and whistles but it was good enough for most applications.
