If the instance is running on the host OS, the description will still return HYPERVISOR.
This will probably depend on the type of Hypervisor being used, from Wikipedia:
Type 1 (or native, bare metal) hypervisors run directly on the host's hardware to control the hardware and to manage guest operating systems. A guest operating-system thus runs on another level above the hypervisor. This model represents the classic implementation of virtual-machine architectures; IBM developed the original hypervisors as bare-metal tools in the 1960s: the test tool, SIMMON, and CP/CMS. CP/CMS was the ancestor of IBM's z/VM. Modern equivalents include Oracle VM Server for SPARC, Oracle VM Server for x86, the Citrix XenServer, VMware ESX/ESXi and Microsoft Hyper-V 2008/2012.
Type 2 (or hosted) hypervisors run within a conventional operating-system environment. With the hypervisor layer as a distinct second software level, guest operating-systems run at the third level above the hardware. VMware Workstation and VirtualBox exemplify Type 2 hypervisors.

So for a Windows system using Hyper-V, the host OS itself is actually virtual.
