Hello all,

I have a L4 Nvidia running on an Openstack bobcat based on Centos 9 Stream.

I have installed NVIDIA-Linux-x86_64-550.127.06-vgpu-kvm.run driver in Host and set up mdev types in nova (OpenStack configuration stuff)

I can start an Openstack instance (Virtual Machine) and I can list the NVidia graphic cart in guest Virtual machine using lspci.

If I install nvidia-linux-grid-550_550.127.05_amd64.deb (guest driver) in guest VM machine I can see the graphic card but I always get:

vGPU Software Licensed Product
    Product Name                      : NVIDIA Virtual Applications

How can I get NVIDIA RTX or vWS?

Regards

I found the cause of the problem. When setting mdev to be used by GPUS, I was setting a L4-4B flavour… For computing nodes it is needed a Q flavour, now I am using a L4-8Q and it is working fine.

may I know what is Q flavour? it is a internal flavour name in your openstack?

Hi,

I am sorry, I say badly the term, I was not talking about openstack flavour, the correct term is Nvidia vGPU profile.

Once you install your Nvidia grid driver you will notice that there are several vGPU profiles and you can only use the *Q and *C to be used as vGPU for vWS.

You can use:

mdevctl types

to list available nvidia profiles
