I'm trying to get it working on a Kvm installation with nested virtualization enabled.

After about 30 seconds the system gets stuck. (If windbg is not connected, it gets stuck immediately).
I don't get any exceptions. It's more like an infinite loop. Windbg shows that Debuggee is running....
Even the windbg .reboot command doesn't work.
The system gets stuck even if I run only airhv.sys without HyperHideDrv.sys.

If I hit Break, the call stack is always the same(When both airhv.sys and HyperHideDrv.sys started):

nt!DbgBreakPointWithStatus

Where

0: kd> u fffff8023b9b0000
fffff8023b9b0000 0f01c1 vmcall
fffff8023b9b0003 c3 ret
fffff8023b9b0004 0000 add byte ptr [rax],al
fffff8023b9b0006 0000 add byte ptr [rax],al

Ofc I can't step into vmcall.
Cause I'm not very good at debug and hypervisor development, but I suspect I need to connect a second windbg for that.
