proactivelabs/packer-windows — reverse-engineered prompt

Build me a small repo that can create ready to use Windows VM images for QEMU and libvirt. I want templates for Windows 10 22H2, Windows 11 23H2, Windows Server 2019, and Windows Server 2022. The images should come up with WinRM, RDP, and SSH enabled, use vagrant for both username and password, install Chocolatey, QEMU guest tools, and VirtIO drivers, and run Windows updates during the build so they are current.

Please make it easy to kick off builds with simple commands, including a way to initialize plugins first and a make target to build everything. I also want a headless switch for debugging, support for custom ISO URL and checksum values, the ability to swap in a different autounattend file, and options for the core editions of the server images. If possible, keep the main customization point in one obvious script, support turning off sysprep, and leave a simple file based signal so I can tell when the machine has finished its first boot setup. Look up current docs online if you need to.
