    Hi Karl! Thanks for trying Azure Stack HCI!

     

    The short answer is what you're seeing is actually expected. The reason is that officially, Azure Stack HCI is only supported on physical hardware. And in some nuances, it's not the same as nested virtualization. More specifically, because Virtual Secure Mode (VSM) is enabled by default, that "hides" necessary virtualization extensions from the Hyper-V compatibility checker. That said, if you use Enable-WindowsOptionalFeature, it will bypass the compatibility checker and should successfully enable Hyper-V. So, try this:

    Enable-WindowsOptionalFeature -Online -FeatureName 'Microsoft-Hyper-V'

    Here's a slightly longer explanation for those curious: https://twitter.com/pronichkin/status/1294308601276719104
