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.-------------------------------------------------Brian Schott, CTONimbis Services, Inc.ph: 443-274-6064 fx: 443-274-6060On Aug 14, 2013, at 6:03 AM, Bob Ball <bob.ball@citrix.com> wrote: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-xenserver-eg-gpu-hypervisor.html
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.

Subject: [openstack-dev] GPU passthrough support blueprints for OpenStack
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the Cactus timeframe (while wearing a different hat) that are pretty out of
date.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:

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?
