We currently do not support vGPU in a Linux guest. That said, tell me more about your use case? What hypervisor stack are you on?

Will there be support for Linux guests?

Currently only passthrough (direct connection) is available for Linux Guests. Also, KVM does not support vGPU it is currently only available on XenServer and will appear on vSphere in the next major release.

Correct.

I use the KVM hypervisor, and I am interested how to implement that KVM support VGPU.Can you give me some advice? I hava bought the nvidia grid k1 and I readlly want to research the detail of GPU virtualization. Carter, South China University of Technology. Email:541658708@qq.com

KVM currently only supports GPU passthrough. Note that in an update to my comments above, GRID 2.0 now supports vGPU in Linux for Workstation profiles.

Jason, what do you mean by: "GRID 2.0 now supports vGPU in Linux for Workstation profiles." Are you simply referring to VFIO aka passthrough for the Grid GPUs ? I am pretty sure I saw the updated kernel from this year get vGPU support. Any thoughts ? Thanks.

(Virtual Workstation and above). So you can share the single gpu with multiple Linux VM's. http://www.nvidia.com/object/grid-technology.html Passthrough is supported in all versions of GRID. mcerveny believes that all new features should be back ported, unfortunately our Engineering feels otherwise.

Thanks MCerveny and Jason. We are looking to leverage NV Grid for VDI, we'd like to use Red Hat RHEV to do this. I was informed that RH is working with Nvidia to do a grid manager integration into the KVM hypervisor before we can take advantage of vGPU. What would be the recommended Nvidia cards for this, would it still be the K1 and K2 or a different one ? aka newer model. PS: The hosts are on RHEV and VMs are Windows 7/10 Enterprise. We may even throw terradicci into the mix to output to a zero client.

[/quote] We can't comment on this until it's released, though it's safe to assume the latest release will be supported. If you're using Windows guests today, consider XenServer as an alternative with full support of vGPU. You can trail on this platfrom then migrate to RHEV once it's released.
