I consider DMI checks to be too fragile here - in particular with the eventual passing through of host DMI attributes to guests, this sets you up for mistakes. Instead, I would envision you scanning the whole CPUID range "reserved" for virtualization (starting at 0x40000000) and see whether you get back anything other than the Hyper-V identification (much like the way xen_cpuid_base() scans for the Xen range). Of course that's under the premise that you're right in assuming Hyper-V would never emulate any other hypervisor's interface.
