kholia/OSX-KVM ? reverse-engineered prompt

Build me a simple project that lets me run macOS in a virtual machine on a Linux PC using QEMU and KVM.

I want the setup to guide me through downloading the macOS installer, creating the virtual disk, and booting it with OpenCore so I can install recent macOS versions like Monterey, Ventura, or Sonoma. It should support both a normal desktop style launch and a headless mode too. If possible, make it easy to use with virtual machine tools later, and include clear notes for things like networking, screen resolution, and passing through extra hardware.

Please keep it practical and beginner friendly, since I just want to follow the steps and get a working Virtual Hackintosh without needing a real Mac. If you need current setup details, look up the latest docs online and make sure the instructions still work.
