GPU card is not detected in Azure RHEL 7.3 VM

I have created Azure VM with 2 GPU cards. Only one get detected.
In /var/log/messages file I can see this entry - nvidia 3130:00:00.0: can’t derive routing for PCI INT A

I have installed CUDA 9.2 kit.

Any help in fixing this issue ?

what is the output of the below commands?

lspci | grep NVIDIA

Here is the output of the above commands
[root@hazr022 sanfern]# lspci | grep -i nvidia

It appears to me that you are using NCv3 instance.
Can you confirm that you are using the Standard_NC12s_v3 instance? Because if you are using Standard_NC6s_v3 , it will have only one gpu.
Could you provide output of the below

nvidia-smi -L

what is the result of:


What’s the output of

ls -l /dev/nvidia*

could you locate the deviceQuery and execute it and provide its output?

sudo apt-get install mlocate
sudo updatedb
locate deviceQuery

then go to the path if it got found and shown [e.g in my case it is /usr/local/cuda-9.2/samples/bin/x86_64/linux/release/deviceQuery]
and what I execute to navigate to the path is

cd /usr/local/cuda-9.2/samples/bin/x86_64/linux/release/

then navigate to that path and execute


You said you have installed 9.2 cuda kit. Did you use runfile or network method? Did you install driver or toolkit or both if you have used the runfile method? [it has separate sections for toolkit and video driver. Though it appears that you have installed the driver].
Normally when I had issues with Azure GPU VM’s I tried to check running other types of instances for determining the cause or engaged in conversation with their support until the issue got clarified.

Some references:

if it would return 1 on


, try



I am using Standard_NC12s_v3. This issue resolved after reinstalling Linux Integration Services for Hyper-V and Azure.

thank you for the update.
Glad to know you have managed to resolve the issue.
In case you will have more GPU works in future , do not hesitate to let me know.
I am looking for PhD and I am gathering practical GPU experience that I would apply toward writing a thesis in the future[If I will have time to do so and will find a scientific adviser].

Thanks Andrey and good luck for your thesis. As per documentation nvidia driver 384.111 is supported on RHEL 7.3 and not on in RHEL7.5. This driver installs without error but nvidia-smi - No devices were found. Any plans to support 384.111 on RHEL 7.5

Trying to build nvidia driver 384.111 on RHEL 7.5, I am getting following error.
