zanzu Posted September 28, 2021 Share Posted September 28, 2021 Hi, I have completed the build of the Unraid server and have a few VMs, Dockers and Shared folders. The server is quite stable. I have two VMs (Windows 10 and BigSur 11.6) booting off NVMe drives. The Win10 VM ( a gaming setup) successfully passthrough a GTX960 GPU and a USB 3.0 controller. My son has been playing ForthNite on this and it's quite stable. The Big Sur 11.6 VM with USB 3.0 passthrough and a 10GB Asus Aquantia card has been stable for a month or so. Recently I tried to passthrough a Sapphire Nitro AMD Radeon 5500XT 8GB. The VM started but for some strange reason it's not booting off the NVMe drive; it's trying to do a PXE boot (Start PEX over IPv4). Eventually it timed out and drops me into the UEFI shell. After checking the boot order, I notice the NVMe drive is not listed, only, what seems to be, the internal NICs. Anyone faced a similar issue and how did you resolve it? The only change to the VM was passing through the Nitro card. The Win10 VM with the GTX960 stable and no issue.. Best Regards Quote Link to comment
zanzu Posted October 2, 2021 Author Share Posted October 2, 2021 Quick update: I removed the 5500XT due to instability with the server; The system would reboot whenever I try to shutdown the VM. After some research, it seems the AMD reset bug is fixed in the 6000 series cards and the patch/module approach for the 5000 series card is not working for me. Best solution is to remove the card from the system and purchase a 6800 GPU. Quote Link to comment

zanzu Posted October 2, 2021 Author Share Posted October 2, 2021 Yeah, I checked. I'll hold off for the moment. Does anyone know of a cheaper card that's supported by Big Sur and VFIO (supports FLR)? Quote Link to comment
ghost82 Posted October 2, 2021 Share Posted October 2, 2021 (edited) https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/amd-gpu.html https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/nvidia-gpu.html#native-nvidia-gpus The lists may be a little outdate lacking or giving partially wrong info on newer gpus, like the 6000 amd series. Notes: 1. consider the amd reset bug, since we are running mac os in a vm 2. if I were you I would wait for the official release of monterey: some gpu families are being dropped (ex nvidia kepler). It would be a shame to buy an "old" gpu and not being able to run it on monterey too Edited October 2, 2021 by ghost82 Quote Link to comment

ab5g Posted October 3, 2021 Share Posted October 3, 2021 (edited) I have a msi aero itx Rx560 4G with no reset bug on it. You can try that. EDIT: On Linux VM's - I do get error 127 with this Graphics card. Edited October 10, 2021 by ab5g Quote Link to comment
