thisguyhere Posted June 29, 2020 Share Posted June 29, 2020 (edited) Tried searching for this but didn't even know how to phrase it right. So this is what's happening. Got a VM with GPU passed in - VM is a nvme passthrough. << This part's working, cool. Got a second GPU intended to handle Plex transcodes. NVIDIA plugin installed, drivers installed, GPU passed into Plex container, Plex setting to enable HW transcoding done. Plex is running, cool. Now, when I play something through Plex and force a transcode, the VM freaks out and start freezing and just being generally unusable. In fact, without even playing anything on Plex, if I run nvidia-smi through terminal, the VM also starts to lock up and freaks out. So it appears the two GPUs in my system are linked and putting one under load is affecting the other?

TIE Fighter Posted June 30, 2020 Share Posted June 30, 2020 What is your setup? In what slot are the two gpu:s connected? Quote Link to comment

Actually I just tried running Plex with HW transcoding while the VM is shut down, and it definitely isn't working normally. On the previous server, using the same GPU (1050), streams with HW transcode would play almost immediately. Right now, it hangs for a while. And then if I play another stream, nvidia-smi reports only one process despite two streams. Previously all streams would be reported in nvidia-smi. There's definitely something funky going on, will need more troubleshooting. Edited June 30, 2020 by thisguyhere Quote Link to comment
thisguyhere Posted July 1, 2020 Author Share Posted July 1, 2020 Hm...all I did was swap the gpus in each other's pcie slots and it's resolved this issue. Not sure why that would have an impact, but...there you go. Quote Link to comment
scorcho99 Posted July 1, 2020 Share Posted July 1, 2020 Is there a reason you have all the acs override options on? I'm mostly asking because I don't know if its required for this chipset or not since its so new! Quote Link to comment
