xinze.zh Posted September 24, 2020 Share Posted September 24, 2020 I have created a ubuntu 20.04 LTS VM on Unraid 6.9.0 beta25. I want to passthrough the GTX 1080 to use cuda to train Neural Network. I can find the GTX 1080 device on VM by lspci command, however, the driver I installed failed to find the device, which shows: No devices were found and the dmesg | grep NVRM shows: [ 3.198085] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 450.66 Wed Aug 12 19:42:48 UTC 2020 [ 7.992666] NVRM: GPU 0000:05:00.0: RmInitAdapter failed!
