      AMD cards are indeed far better for both vGPU and GPU passthrough: it just works.

        If only they made a LP vGPU card.... Looks like a WX4100 will have to do.

          @anthonyh yeah, I also got this note in version 8.1. I just don't know why. But my VM can't see Rx580, that's the problem

          @olivierlambert man, please, I got problem right here with AMD GPU. Please help.

          @jmccoy555 You can use the GUI. I checked, the code changes as if you do make it in CLI. please check the newest version 8.1

            @anthonyh Google code 43 NVIDIA...... Basic translation is we want to stop you doing this with a consumer card in a VM. There are solutions I believe.

            Yes, using Nvidia card supporting GPU passthrough 😛

            Otherwise, there's "border line" patches on Windows drivers available on GitHub, but we won't find those for you 😉

            Well, this card is technically in the Quadro family, so I was hoping it'd work. I see solutions for libvirt/KVM, but not Xen. Any "nudge" would be greatly appreciated if anyone is willing. This is just a test environment. If the application works in this setup we'll buy proper hardware and go the AMD route.

              I think I might have found the GitHub driver patch @olivierlambert was referring to...

                  Thanks for the tip!! Working in 8.1 in XCP-ng Center and also XO 🙂

                  Also, dont think there is a need to 'hide' the GPU from Dom0 now??

                  edit: Did a fresh install, no need to 'xen-pciback.hide' when assigning via XO or XCP-ng center. This was with AMD as they play nicely, not sure about NVIDIA.

                        @imtrobin No, AMD. Currently a WX4100 (as its LP and fits into a 2U server) but have also had a RX580 working before.
