While this patch does seem to help I still have problems. After I shutdown the VM I'm often unable to suspend or shutdown the host. Amongst other symptoms lspci and lshw both hang giving no output. I had none of these issues with an old 7950 I had installed before the 290x. I've come to the conclusion that the 290x is worth more to me on eBay than in my machine. Question is would I be better off with nVidia and if so does anyone have any feedback with regard to GTX 970 and 980 cards? Thanks in advance Hi Dik, I have only used R9 270X when I was trying to passhtrough it on Xen and it worked flawlessly. But then I was intrigued to NVIDIA's rich feature set, so I gambled myself trade my R9 270X with GTX 770. Xen could not pass the GPU at the time, so I tried for the first time KVM/VFIO approach. It went success using VGA/legacy mode but then UEFI/OVMF way emerged. I changed my QEMU script and NVIDIA still proved to be quite stable to be passed through to guest VM, although with some workarounds like hiding KVM CPUID and Hyper-V custom vendor ID needs to be addressed to tame the recent NVIDIA driver. Kudos to Alex Williamson for this [1]. Since then, I always upgrade myself with NVIDIA. These cards have been personally tested by me under KVM/VFIO and all of them supports UEFI thus OVMF approach: 1.) NVIDIA GeForce GT 730 (Inno3D) 2.) NVIDIA GeForce GTX 770 (Gigabyte) 3.) NVIDIA GeForce GTX 780 (ASUS) 4.) NVIDIA GeForce GTX 980 (Gigabyte) 5.) NVIDIA GeForce GTX 980 Ti (MSI) [1] https://lists.gnu.org/archive/html/qemu-devel/2015-10/msg00662.html Best regards, Okky Hendriansyah
