Description of problem: CU wants to ues GPU sharing in Openshift on Openstack instance with GPU. They wants to got official support with guide about it. I'll put my finding additional comment. Version-Release number of selected component (if applicable): RHOCP 4.x RHOSP16.1
Hello, I'd like to get some clarifications on the request. On the OpenStack side of things, we have documentation around configuring PCI passthrough [1], which can be used to pass through any PCI device to an instance, including GPUs. We also have a chapter on configuring virtual GPUs [2] - the use case is similar to [1], with the main difference that [2] is only for GPUs, and the instance receives a virtual GPU that's a "slice" of a single physical GPU, whereas in [1] the instance receives the entire PCI device. Give these two pieces of documentation, what's missing to enable your use case? Do you need OpenShift-specific documentation on how to consume a (virtual) GPU and make it available to containers?

Hi Artom, Sorry and Thank you for the update. CU is wondering that that architecture is full supported by Red Hat. I was confused about it in our internal DOCs. Could I tell CU it is full supported? and If it possible they want to some official DOC and architecture info about it. (if it possible) THank you, Regards, YoungCheol.
Hi again, I'm still not fully clear on the use case. Are you looking for official documentation on running the NVIDIA GPU Operator in an OpenShift GPU worker on top of an OpenStack VM with a passed-through GPU? In other words, an official version of what Kevin describes in his blog post that you linked [3]? [3] https://kdjlab.com/openshift-4-6-on-openstack-with-gpu-operator-v1-3/

Thank you, Regards, YoungCheol.
