 No. We told about "experimental" because given we didn't have a CI
verifying the features, we were not sure operators were not having a lot of
bugs. After 2 cycles, we don't have a lot of bugs and some operators use
it, so we could remove the "experimental" situation.

Make sure you use the correct grid server driver from nvidia and then
follow those steps :
https://docs.nvidia.com/grid/6.0/grid-vgpu-user-guide/index.html#install-vgpu-package-generic-linux-kvm

Once the driver will be installed (make sure tho you remove first the
nouveau driver as said above) and the system rebooted, you should see the
above sysfs directory.

[openstack-dev] [NOVA] nova GPU suppot and find GPU type

[Manuel Sopena Ballesteros]

Dear Nova community,

This is the first time I work with GPUs.

I have a Dell C4140 with x4 Nvidia Tesla V100 SXM2 16GB I would like to setup 
on Openstack Rocky.

I checked the documentation and I have 2 questions I would like to ask:


1.   Docs (1) says As of the Queens release, there is no upstream 
continuous integration testing with a hardware environment that has virtual 
GPUs and therefore this feature is considered experimental. Does it means nova 
will stop supporting GPUs? Is GPU support being transferred to a different 
project?

2.   I installed cuda-repo-rhel7-10-0-local-10.0.130-410.48-1.0-1.x86_64 on 
the physical host but I can't find the type of GPUs installed (2) 
(/sys/class/mdev_bus doesn't exists). What should I do then? What should I put 
in 
devices.enabled_vgpu_types?
