Qemu says opengl is disabled

[colourfullyy]

Hi, When I try to run these commands: qemu-system-aarch64 \ -machine virt,accel=hvf,highmem=off \ -cpu cortex-a72 -smp 2 -m 4G \ -device intel-hda -device hda-output \ -device virtio-gpu-pci \ -device virtio-keyboard-pci \ -device virtio-net-pci,netdev=net \ -device virtio-mouse-pci \ -display cocoa,gl=es \ -netdev user,id=net,ipv6=off \ -drive "if=pflash,format=raw,file=./edk2-aarch64-code.fd,readonly=on" \ -drive "if=pflash,format=raw,file=./edk2-arm-vars.fd,discard=on" \ -drive "if=virtio,format=raw,file=./hdd.raw,discard=on" \ -cdrom focal-desktop-arm64.iso \ -boot d

and

qemu-system-aarch64 \ -machine virt,accel=hvf,highmem=off \ -cpu cortex-a72 -smp 2 -m 4G \ -device intel-hda -device hda-output \ -device virtio-gpu-pci \ -device virtio-keyboard-pci \ -device virtio-net-pci,netdev=net \ -device virtio-mouse-pci \ -display cocoa,gl=es \ -netdev user,id=net,ipv6=off \ -drive "if=pflash,format=raw,file=./edk2-aarch64-code.fd,readonly=on" \ -drive "if=pflash,format=raw,file=./edk2-arm-vars.fd,discard=on" \ -drive "if=virtio,format=raw,file=./hdd.raw,discard=on"

nothing happens except this output: qemu-system-aarch64: OpenGL support is disabled

I've never seen anything like this before, I would appreciate any help. (I'm running an m1 macbookair with macos big sur 11.4)

I’d say you probably have stock qemu installed. Try executing qemu-system-aarch64 --version

When installing both stock version and the version from this repo, only one symlink “wins”

[knazarov]

If the symlink points to the proper place, try running brew reinstall --verbose -s qemu-virgl 2>&1 | tee build.log and attach the resulting build.log here. I'll check that the configuration phase properly detects libANGLE.

Having this same issue on an Intel Mac. The output when trying to install Fedora or any other OS is:

qemu-system-x86_64: OpenGL support is disabled

Any new insight since the last post on this issue?

Same issue on Apple M1 and I just installed QEMU with brew on 06/30/2024. I tried running brew reinstall --verbose -s qemu-virgl 2>&1 | tee build.log anyway as I do not see that you received a log previously, but I got the following error Error: No available formula with the name "qemu-virgl".. Is there a different version you like a build.log on?

I have a zsh script for creating and running my QEMU VM. I have been playing around with the settings so that setup and start options for qemu-system-aarch64 do not exactly match. The poor graphical performance is the same either way. The relevant functions are:

QEMU_CreateVMNixOS() {
    echo "Retreiving environment variables..."
    dd if=/dev/zero conv=sync bs=1m count=64 of=ovmf_vars.fd
    echo "Creating NixOS image..."
    qemu-img create -f qcow2 nixos.qcow2 20G
    echo "Setting up NixOS..."
    qemu-system-aarch64 \
      -cpu host -M virt,accel=hvf,highmem=on \
      -m 4096 \
      -drive file=/opt/homebrew/share/qemu/edk2-aarch64-code.fd,if=pflash,format=raw,readonly=on \
      -drive file=ovmf_vars.fd,if=pflash,format=raw \
      -drive if=none,file=nixos.qcow2,format=qcow2,id=hd0 \
      -device virtio-blk-device,drive=hd0,serial="dummyserial" \
      -device virtio-gpu-pci \      
      -device virtio-keyboard
      -device virtio-mouse \
      -device virtio-net-device,netdev=net0 \
      -serial telnet::4444,server,nowait \
      -netdev user,id=net0 \
      -cdrom /**/qemu/nixos-minimal-24.05.2150.89c49874fb15-aarch64-linux.iso \
      -full-screen
}
QEMU_StartNixOS() {
    echo "Start up NixOS..."
    qemu-system-aarch64 \
      -cpu host -M virt,accel=hvf,highmem=off \
      -m 2048 \
      -drive file=/opt/homebrew/share/qemu/edk2-aarch64-code.fd,if=pflash,format=raw,readonly=on \
      -drive file=ovmf_vars.fd,if=pflash,format=raw \
      -drive if=none,file=nixos.qcow2,format=qcow2,id=hd0 \
      -device virtio-blk-device,drive=hd0,serial="dummyserial" \
      -device virtio-gpu \
      -device intel-hda \
      -device virtio-keyboard \
      -device virtio-mouse \
      -device virtio-net-pci,netdev=net0 \

      -netdev user,id=net0 \
      -full-screen
}

Error qemu-system-aarch64: OpenGL support is disabled occurs when display cocoa,gl=on is added to the above commands. The only available gpu options that allow the VM to start are virtio-gpu and virtio-gpu-pci. virtio-gpu-gl is not available and produces error qemu-system-aarch64: -device virtio-gpu-gl: 'virtio-gpu-gl' (alias 'virtio-gpu-gl-pci') is not a valid device model name. Of the two available GPU options, neither seem to producing any hardware acceleration as there are many graphical glitches. Performance is slow (understandably as it is a VM), but quite a bit slower than expected. Current testing has been with Hyprland.

Running NixOS without a desktop environment, and using terminal interface only works fine and is rather snappy. I can get Tmux going with no lag and no graphical issues.

I also tried UTM, but performance was worse.
