HAXM is a hardware-assisted virtualization engine (hypervisor) that uses Intel Virtualization Technology to speed up IA (x86/ x86_64) emulation on a host machine running Windows or macOS.
For upstream QEMU I think we're looking at patches that add Hypervisor.framework support for MacOS acceleration -- better to use the builtin support from the OS rather than a 3rd party kernel extension I think. The Android release notes (https://developer.android.com/studio/releases/emulator.html) say it supports both Hypervisor.framework and HAXM, with H.f being on by default -- are you saying that H.f has poor performance compared to HAXM?
