Don't know if you caught this on the main dev list.

Thanks for the pointers. I'll try to work with the UCS-ISI team that currently maintains those stories and see if we can reconcile or close the old blueprints.

Hi Brian,

Instead of specific GPU pass-through there are blueprints for generic PCI pass through at https://blueprints.launchpad.net/nova/+spec/pci-passthrough-base - these are being worked on for Havana and we're hopeful they will get in (possibly libvirt only)

In terms of vGPU rather than whole-GPU pass through, the slides are correct that XenServer support is very nearly here: http://www.xenserver.org/discuss-virtualization/q-and-a/nvidia-vgpu-on-xense...

Support for static allocation of vGPU is likely going to be the first phase - and adding it as a resource similar to RAM/CPU isn't likely to be proposed until a second phase.

As such, I think the integration should be very similar to PCI pass through above.

Are there more recent blueprints related to adding GPU pass-through support? All that I can find are some stale blueprints that I created around the Cactus timeframe (while wearing a different hat) that are pretty out of date.

I just heard a rumor that folks are doing Nvidia GRID K2 GPU passthrough with KVM successfully using linux 3.10.6 kernel with RHEL.

In addition, Lorin and I did some GPU passthrough testing back in the spring with GRID K2 on HyperV, libvirt+xen, and XenServer. Slides are here: http://www.slideshare.net/bfschott/nimbis-schott- openstackgpustatus20130618

The virtualization support for GPU-enabled virtual desktops and GPGPU seems to have stabilized this year for server deployments. How is this going to be supported in OpenStack?

Brian
