Description of problem:
I am running a Fedora 42 VM under Hyper-V, with nested virtualization enabled.

I launched Boxes
1. Created a Fedora 41 workstation from download
2. Used UEFI mode, default settings for RAM & disk size
3. VM starts to boot, Tianocore logo is shown
After a few seconds, the VM crashes.

Version-Release number of selected component:
qemu-system-x86-core-2:9.2.0-15.fc42
