It is possible to emulate macOS inside Windows with Qemu. There are a number of difficulties with keyboards, mouse and drivers, but below is a command line that has been verified working with Monterey and WHPX accelerator.

This is useful for testing features and obtaining screenshots, but will not be a reliable system due to continuous updates to Qemu and macOS.

Start by obtaining a copy of the recovery image, for example see: https://github.com/kholia/OSX-KVM

Notes:

• Linux system is needed to download the image using the script from above
• Fix the paths as per your filesystem
• Most CPU flags here may not be essential, but the system will freeze without +xsave
• The BaseSystem image is around 3GB, the installed disk will expand to around 40GB but only 15GB used
• WHPX crashes using separate OVMF CODE & VARS, so combine these to a single file:

copy /B OVMF_VARS.fd + OVMF_CODE.fd OVMF_combined.fd

This was tested using Qemu 7.2.0, on an 2018 Intel i5 host running Windows 10.
