On my brand new Win11 Pro machine (AMD Ryzen 9 7950X) my Visual Studio 2022 Enterprise installation (v17.7.6) doesn't use hardware acceleration when I disable Hyper-V and enable AEHD (or GVM).
Short version
When I start an emulated device via the Visual Studio Android Device Manager this error message shows up and the performance is crazy slow: Hyper-V is not configured. Turn on "Hyper-V" feature to switch to the Native Hypervisor and accelerate your emulator.
When I start it via batch/cmd using "C:\Program Files (x86)\Android\android-sdk\emulator\emulator.exe" -avd pixel_5_-_api_33 everything works fine.
Long version
- I have followed the instructions for android and MAUI.
- I made sure Hyper-V is really off
- I've installed the newest AEHD v2.1 (formerly GVM) from github
sc query aehdsays: RUNNINGemulator-check.exe hyper-vsays: Hyper-V is not installed (C:\Program Files (x86)\Android\android-sdk\emulator\emulator-check.exe)emulator-check.exe accelsays: GVM (version 2.1) is installed and usable.
But most importantly (as mentioned in the short version above): AEHD (hardware acceleration) works when started via cmd.
Why
does Android Device Manager (which has nothing to do with the Android-Studio/Google Device Manager as the AndroidDevices.exe seems to be by Xamarin Inc.) forces me to have Hyper-V installed?
It took me ages, dozens of uninstall/install of AEHD/Hyper-V and luck to find out its an VS issue and not a driver/installation issue.
I've only found one more post on about the same issue here.
I cannot imagine this being a "global" bug and I'm the only one complaining about this...
Any help, thoughts and hints are highly appreciated. Thanks in advance.
PS: I do not want and cannot install/use Hyper-V as an active Hyper-V is incompatible with other software I'm running.

Here I've found the location of the log files of the Device Manager.
My logfile in c:\Users\<user>\AppData\Local\Xamarin\Logs\17.0\*.devicemanager.log looks like this:

So I installed the official v2.0 from the SDK-Manager and tried again:

I reckon its a bug in AndroidDevices.exe as it always starts virtual device with Executing command: "cmd" "/C" "sc" "query" "intelhaxm" which forces HAXM apparently :(
