I'm thinking about trying to leverage offline VHD management to install the VirtIO drivers, so download the Hyper-V Developers Image, and follow this process: https://msdn.microsoft.com/en-us/windows/hardware/commercialize/manufacture/desktop/add-and-remove-drivers-to-an-offline-windows-image
Not something I've tried previously, but I'd assume it can get the job done! I got a response back from Microsoft Windows Dev twitter stating to make a request through their UserVoice channel to have a prepackaged KVM image. I'll post back if I get a chance to try this out. Idea here being not having to spin up the OVA/OVF on another platform prior to uploading to Prism Image Management.
