i think its one of latest windows updates broke airhv driver but i cant find actual reason by myself

estimated1337 avatar Mar 22 '23 21:03 estimated1337

Run DbgView as administrator enable "Capture Kernel" try to start airhv then paste its output here

dbgview64_7pA8UBTbvb interesting that before some windows update it was working and i have intel cpu

estimated1337 avatar Mar 22 '23 21:03 estimated1337

can it be cuz of Hyper-V possibly enabled?

estimated1337 avatar Mar 22 '23 21:03 estimated1337

Yes, nested virtualization is disabled by default in hyper-v

i have disabled Hyper-V and some other related thing in windows components but it doesnt take any effect and also tried commenting vmx support check in airhv and got reasonable bsod

estimated1337 avatar Mar 22 '23 22:03 estimated1337

uploaded minidump of bsod here https://easyupload.io/jkfk0b

also issue may be in Virtualization-Based Security (VBS) windows feature and i dont know why its enabled on my windows in first place (probably some windows update enabled it) and i dont know how to disable it tried following this guide but its still active on my system

estimated1337 avatar Mar 23 '23 12:03 estimated1337

You should disable VBS, because airhv will not work as long as it is enabled

Increasing the virtual machine memory to 4G can solve this problem
