Issue running nixosTest in nested virtualization case on Hyper-V

My setup runs nixos as an hyper-v guest, and I’m having issues with running any type L2 guest. This is especially annoying for nixosTest instances. [ Hardware: Physical CPU (VT-x) ] │ [ L0 Host: Windows 11 + Hyper-V ] │ [ L1 Guest VM: NixOS (Hyper-V VM) ] │ [ L2 Guest VMs: nixosTest framework (QEMU using /dev/kvm) ] On my computer the L2 guest hangs during boot. I’m starting to feel like this setup is not supposed to “just work”. And this is going into territory way...
