All that I can find are some stale blueprints that I created around<br/>the Cactus timeframe (while wearing a different hat) that are pretty out of<br/>date.<br/><br/>I just heard a rumor that folks are doing Nvidia GRID K2 GPU passthrough<br/>with KVM successfully using linux 3.10.6 kernel with RHEL.<br/><br/>In addition, Lorin and I did some GPU passthrough testing back in the spring<br/>with GRID K2 on HyperV, libvirt+xen, and XenServer.
