The previous post discussed the differences in processor functionality provided by Hyper-V's Limit Processor Functionality (LPF) checkbox. You probably want to read through that in order to get the necessary background to understand this final instalment.

In this post I discuss how you can determine:

  1. If your operating system is running on a hypervisor,
  2. The processor feature differences presented for an operating system running directly on hardware versus a parent partition operating system on a hypervisor,
  3. The processor feature differences presented for a child partition operating system running without LPF set versus one that does.

In essence I ran a number of tools and found some minor discrepancies in the results I received from each. The basic premise I followed was to run them on Windows Vista x86, Windows Server 2008 (Parent partition with the Hyper-V RC0 role enabled) and then in a child partition running Windows XP SP3 with the LPF checkbox enabled and disabled.
