Q: Can I manage the client Hyper-V in Windows 8 via System Center 2012 Virtual Machine Manager?

A: No, that client Hyper-V can't be managed by System Center 2012 Virtual Machine Manager (SCVMM). Although the Hyper-V feature in Windows 8 is great for many scenarios, it isn't designed to run enterprise services and isn't a supported platform for management by SCVMM.
