The Hyper-V Administrator tool will show the address for the Hyper-V host, and that address will be needed in the Hyper-V connection details in Spotlight in order to connect. A Hyper-V connection would connect to the machine that hosts / manages the other Virtual Machines associated to it.
You may need to ask your network/admin department for the Hyper-V address, in order to monitor it in Spotlight (if allowed). Otherwise this can remain a Windows connection, without the additional 'Virtualization Overhead' option. Further details can be found here
