When HAXM was proposed for deprecation & removal from QEMU, the suggestion
was that users should switch to Windows' native replacement WHPX, which
QEMU already has support for.

What is the rationale for wanting to introduce a 3rd party hypervisor
solution like AEHD, for the Android emulator, rather than just sticking
with the standard WHPX hypervisor available for Windows ? IIUC, the
Android emulator can already support WHPX according to these pages:
