[Question] OpenGL 3 on Archlinux VM (self.virt_manager)

Does anyone know how to get OpenGL3 to work on an Archlinux VM?
My goal is to be able to run Godot within a VM so that I can have:

  • a reproducible and shareable dev environment

I've tried the following guide:

  1. Edit grub configuration (on Archlinux guest VM) > /etc/default/grub
# Added "amd_iommu=on" to the default configuration line 6 as shown below:
GRUB_CMDLINE_LINUX_DEFAULT"loglevel=3 quiet amd_iommu=on"
  • Run sudo grub-mkconfig -o /boot/grub/grub.cfg
  1. Shutdown Archlinux VM and modify the VM's configurations:

[Virt-Manager VM Tabs]:

Display Spice

  • Listen type: [Address --> None]
  • OpenGL: [disabled --> โœ…]
    • [Laptop DGPU selected]:
      {0000:07:00:0 Advanced Micro Devices, Inc. [AMD/ATI] Rembrandt [Radeon 680M] (render)}

Video Virtio

  • 3D acceleration [disabled --> โœ…]

This results in my VM displaying a mainly white screen with random rainbow artifacts:

I have a feeling that I might need to edit the grub configuration on my host machine however due to running NixOS atm for my laptop,

  • this isn't an option for me at the moment,
    • however I would still appreciate confirmation in knowing that the host grub edit is required/necessary
