FreeBSD 13.1-RELEASE for ARM64 boot in QEMU on Apple Silicon Mac screenshot

Running FreeBSD 13.1-RELEASE for ARM64

  1. Install Xcode from App Store or install Command Line Tools on your Mac running on Apple Silicon.

    xcode-select --install
    
  2. Install Homebrew and QEMU.

    https://brew.sh/

    qemu-system-aarch64 --version
    QEMU emulator version 7.0.0
    Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers
    
  3. Download pre-build EDK II OVMF EFI image for QEMU.

    This EFI image is built from stable202011 tag with additional resolutions in QemuRamfb.c.

    https://gist.github.com/niw/4f1f9bb572f40d406866f23b3127919b/raw/f546faea68f4149c06cca88fa67ace07a3758268/QEMU_EFI-cb438b9-edk2-stable202011-with-extra-resolutions.tar.gz

    To build it from the source code for adding more resolutions, see the following section.

  4. Prepare pflash for non-volatile variable store, such as screen resolution.

    mkdir ~/qemu-vm/
    cd ~/qemu-vm/
    tar xvf ~/Downloads/QEMU_EFI-cb438b9-edk2-stable202011-with-extra-resolutions.tar.gz
    dd if=/dev/zero of=pflash0.img bs=1m count=64
    dd if=/dev/zero of=pflash1.img bs=1m count=64
    dd if=QEMU_EFI.fd of=pflash0.img conv=notrunc
    dd if=QEMU_VARS.fd of=pflash1.img conv=notrunc
    
    • This step is optional, you can use -bios QEMU_EFI.fd instead of -drive ...if=pflash lines in the next step,
      but in that case, any changes in EFI will not be persistent.
  5. Download FreeBSD 13.1-RELEASE for ARM64 raw VM image xz-compressed file

    https://ftp2.uk.freebsd.org/pub/FreeBSD/releases/VM-IMAGES/13.1-RELEASE/aarch64/Latest/FreeBSD-13.1-RELEASE-arm64-aarch64.raw.xz

    (See https://docs.freebsd.org/en/books/handbook/mirrors/ for a list of mirrors to choose from.)

  6. Decompress xz-compressed file, keeping a copy of the original compressed file

    Keeping a copy of the original file is convenient because then you can use it if you want to create additional VMs later. Just be careful not to overwrite the image of your first VM when you want to make a second VM though 😛

    mv ~/Downloads/FreeBSD-13.1-RELEASE-arm64-aarch64.raw.xz .
    unxz -k FreeBSD-13.1-RELEASE-arm64-aarch64.raw.xz
    
  7. Run your FreeBSD 13.1-RELEASE for ARM64 VM

    ~/src/qemu/build/qemu-system-aarch64 
      -M virt 
      -accel hvf 
      -cpu host 
      -smp 4 
      -m 4096 
      -drive file=pflash0.img,format=raw,if=pflash,readonly=on 
      -drive file=pflash1.img,format=raw,if=pflash 
      -device virtio-gpu-pci 
      -display default,show-cursor=on 
      -device qemu-xhci 
      -device usb-kbd 
      -device usb-tablet 
      -device intel-hda 
      -device hda-duplex 
      -drive file=FreeBSD-13.1-RELEASE-arm64-aarch64.raw,format=raw,if=virtio,cache=writethrough 
      -nographic 
      -serial mon:stdio
