Description okok102928 2017-07-28 05:38:45 EDT
Description of problem:


I am sorry that my English is immature.

A simple inquiry,

I would like to ask you some questions about graphical virtualization in RHV(RHEV) or KVM.

1. Is the vGPU sharing function (like nvidia GRID) supported by RHV (RHEV) or KVM? (Or like hyper-v's remoteFX vGPU sharing)

2. If item 1 is not supported, when will the feature be reflected?

3. In addition, Is there a way to share the graphics card on the hypervisor node across multiple VMs? No matter how you implement it within the redhat virtualization platform. (And the introduction of third-party solutions.)

Hi,

if you have a Red Hat support contract, it is best to open a support case for this type of questions.

It is supported as Tech Preview in RHV 4.1.4 with RHEL 7.4 Hypervisors and will be fully supported with RHV 4.2 release for NVIDIA Tesla Grid cards (like M60)

Please note that some additional steps are required to get this working. If you are interested in this functionality and how to set it up, please open a support case. You also need to have a business relationship with NVIDIA in order to get the appropriate drivers.

See above.

This is what vGPU is all about. Sharing the same GPU across multiple VMs.
