There are "forks" (replicas) of Qemu for Android (world of ARM, not x86-based cpu) or (and) iOS (Apple Watch). I don't think that any kind of Hyper-V used on that device sets...

maybe, my understanding of Hyper-V technology wrong... What's Hyper-V, in short? Hardware virtualization on x86-based cpu?...

Hi gerhart,

Your collection of Hyper-V research is great, but I notice that you haven't add these two slides:
https://www.blackhat.com/us-22/briefings/schedule/#directx-the-new-hyper-v-attack-surface-26442
https://github.com/howknows/hypervvulners_bhusa2021

They are all about hyper-v research, maybe you can add them to "HyperResearchesHistory".

Thank you for your excellent work. I have studied a lot after I read it and I think I should write something.

• I haven't found computecore.dll in your Hyper-V, WDAG and WSB components images. It has appeared since Windows 10 Version 1809. It's the dynamic library for Host Compute System APIs. It's also in the public. Here is the documentation: https://docs.microsoft.com/en-us/virtualization/api/hcs/overview
• I haven't found computenetwork.dll in your Hyper-V, WDAG and WSB components images. It has appeared since Windows 10 Version 1809. It's the dynamic library for Host Compute Network APIs. It's also in the public. Here is the documentation: https://docs.microsoft.com/en-us/windows-server/networking/technologies/hcn/hcn-top
• Maybe you can provide the link for https://github.com/microsoft/hcsshim to help people to discover the undocumented Host Compute Service APIs and Host Network Service APIs in vmcompute.dll. It may also helpful for people to use documented Host Compute System APIs and Host Compute Network APIs because the most JSON definitions for them can be shared.
• I think vmcompute.dll maybe not the Windows Container specific because it will be installed if we enable any Windows feature related to Hyper-V.
• I hope my work (https://github.com/M2Team/NanaBox) can be mentioned in your Hyper-V research history list. Because I want to help more people more easier to write a third-party Hyper-V client based on Host Compute System APIs.
