+VMApple machine emulation
+========================================================================================
+
+VMApple is the device model that the macOS built-in hypervisor called "Virtualization.framework"
+exposes to Apple Silicon macOS guests. The "vmapple" machine model in QEMU implements the same
+device model, but does not use any code from Virtualization.Framework.
+
+Prerequisites
+-------------
+
+To run the vmapple machine model, you need to
+
+ * Run on Apple Silicon
+ * Run on macOS 12.0 or above
+ * Have an already installed copy of a Virtualization.Framework macOS 12 virtual
+ machine. Note that newer versions than 12.x are currently NOT supported on
+ the guest side. I will assume that you installed it using the
+ `macosvm <https://github.com/s-u/macosvm>`__ CLI.
+
+First, we need to extract the UUID from the virtual machine that you installed. You can do this
+by running the shell script in contrib/vmapple/uuid.sh on the macosvm.json file.
+
+.. code-block:: bash
+ :caption: uuid.sh script to extract the UUID from a macosvm.json file
+
+ $ contrib/vmapple/uuid.sh "path/to/macosvm.json"
+
+Now we also need to trim the aux partition. It contains metadata that we can just discard:
+
+.. code-block:: bash
+ :caption: Command to trim the aux file
+
+ $ dd if="aux.img" of="aux.img.trimmed" bs=$(( 0x4000 )) skip=1
+
+How to run
+----------
+
+Then, we can launch QEMU with the Virtualization.Framework pre-boot environment and the readily
+installed target disk images. I recommend to port forward the VM's ssh and vnc ports to the host
+to get better interactive access into the target system:
+
+.. code-block:: bash
+ :caption: Example execution command line
+
+ $ UUID="$(contrib/vmapple/uuid.sh 'macosvm.json')"
+ $ AVPBOOTER="/System/Library/Frameworks/Virtualization.framework/Resources/AVPBooter.vmapple2.bin"
+ $ AUX="aux.img.trimmed"
+ $ DISK="disk.img"
+ $ qemu-system-aarch64 \
+ -serial mon:stdio \
+ -m 4G \
+ -accel hvf \
+ -M vmapple,uuid="$UUID" \
+ -bios "$AVPBOOTER" \
+ -drive file="$AUX",if=pflash,format=raw \
+ -drive file="$DISK",if=pflash,format=raw \
+ -drive file="$AUX",if=none,id=aux,format=raw \
+ -drive file="$DISK",if=none,id=root,format=raw \
+ -device vmapple-virtio-blk-pci,variant=aux,drive=aux \
+ -device vmapple-virtio-blk-pci,variant=root,drive=root \
+ -netdev user,id=net0,ipv6=off,hostfwd=tcp::2222-:22,hostfwd=tcp::5901-:5900 \
