Hello, I have a problem and I would like to get some new opinion on it. I have a Fedora 25 server running on a i7-6700K and GTX1060 computer. I set it up as a VM host following this guide and then this one to create VM. I even enabled <kvm> <hidden state='on'/> </kvm> Then I installed Windows 10 and latest GeForce drivers and I could run a steam game. Next I installed a VM guest Fedora 25 with cuda-8.0 toolkit and drivers. My problem is that nvidia-smi returns Unable to determine the device handle for GPU 0000:00:07.0: Unknown Error while lspci | grep NVIDIA returns 00:07.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] (rev a1) 00:08.0 Audio device: NVIDIA Corporation Device 10f1 (rev a1)
I have spent two days on this, googling and reinstalling. I cannot run caffe on GPU without it. Did anyone have a similar issue?
From what i have read nVidia drivers do not cooperate if they detect they're installed on a VM. Perhaps someone can correct but that was my understanding of it. I have not dug into it because i'm on Team Red. (The one that's not crap)
Yeah, there's a good post that @GrayBoltWolf posted a few weeks back, he goes into detail about getting GPU passthrough working with team green.
Read through this:
About 2/3 down the OP, you'll find some libvirt xml for disabling hyperv and kvm. Use that and you'll be in good hands. I had it working for about a month with my 970.
Thank you for the info. I have tried editing it maunally, but it seems it needs to be done via virsh edit . Problem is that I cannot install virsh, because the host OS is using a bridge. It connects to the internet correctly, but dnf and yum do not seem to cooperate with the bridge. This is a networking broblem and I should find a solution easily.
Well I found this out, and the question is now how to bypass this issue. I have found info that this refusal of cooperation is a "unintentional and unfortunate bug". However it has been left unfixed for a long time. Problem is I need team green for GPU acceleration for machine learning and neural nets. Thankfully AMD announced Radeon Instinct GPUs so in the future we might have a opensource alternative.
It works! Once I selved the network issues (bad bridge config on my behalf), I was able to isntall virsh and only added the <kvm> <hidden state='on'/> </kvm> nad the NVIDIA drivers recognized the card. Thanks for all the help and tips. Hope someone finds this useful.
