I’m pretty sure GPU passthrough does work in Qubes HVMs, although I haven’t tried it myself. Here are three quick and recent tutorials I found including one with a newer VirtualGL approach that offloads work instead of passing the entire card. https://neowutran.ovh/qubes/articles/gaming_windows_hvm.html https://neowutran.ovh/qubes/articles/gaming_windows_hvm.html https://forum.qubes-os.org/t/nvidia-gpu-passthrough-into-linux-hvms-for-cuda-applications/9515 https://forum.qubes-os.org/t/nvidia-gpu-passthrough-into-lin... https://forum.qubes-os.org/t/seamless-gpu-passthrough-on-qubes-os-with-virtualgl/20265 https://forum.qubes-os.org/t/seamless-gpu-passthrough-on-qub... Yes, the passthrough is probably a huge avenue for attacks. Possibly VirtualGL too, I know less about that.

  That's the same as the first link in your previous comment. Did you manage to edit it after all?

    Yes, thank you.

Does this fix the Code 14 issue with NVIDIA cards? That is why I had to switch to KVM back in 2016, as KVM has support for bypassing NVIDIA's "bug" which prevents using consumer cards in a virtual environment. I have been away from Qubes for 7 years now so I'd hope some form of improvement has been made.

  Are you referring to Code 43? I believe the NVIDIA drivers after version 465 may not have this issue. Here’s a report of this working on Qubes/Xen: https://forum.qubes-os.org/t/qubes-gpu-passthrough/661/12 https://forum.qubes-os.org/t/qubes-gpu-passthrough/661/12 However you may need to hide the virtualization from some games or other software, where Qemu/KVM can be more flexible. There’s a project and some discussion to use these with Qubes, but it’s early days: https://github.com/nrgaway/qubes-kvm-dev https://github.com/nrgaway/qubes-kvm-dev https://forum.qubes-os.org/t/porting-qubes-to-hypervisors-other-than-xen-abstracting-the-functionality-early-stage/23478 https://forum.qubes-os.org/t/porting-qubes-to-hypervisors-ot...

    Yes sorry, I meant 43. It's been a long time :) > However you may need to hide the virtualization from some games or other software, where Qemu/KVM can be more flexible. How prevalent is this? Is it basically just multiplayer games employing anticheat?
