Hi Irena, This is Robert Li from Cisco Systems. Recently, I was tasked to investigate such support for Cisco's systems that support VM-FEX, which is a SRIOV technology supporting 802-1Qbh. I was able to bring up nova instances with SRIOV interfaces, and establish networking in between the instances that employes the SRIOV interfaces. Certainly, this was accomplished with hacking and some manual intervention. Based on this experience and my study with the two existing nova pci-passthrough blueprints that have been implemented and committed into Havana (https://blueprints.launchpad.net/nova/+spec/pci-passthrough-base and https://blueprints.launchpad.net/nova/+spec/pci-passthrough-libvirt), I registered a couple of blueprints (one on Nova side, the other on the Neutron side):
https://blueprints.launchpad.net/nova/+spec/pci-passthrough-sriov https://blueprints.launchpad.net/neutron/+spec/pci-passthrough-sriov in order to address SRIOV support in openstack. Please take a look at them and see if they make sense, and let me know any comments and questions. We can also discuss this in the summit, I suppose. I noticed that there is another thread on this topic, so copy those folks from that thread as well. thanks, Robert On 10/16/13 4:32 PM, "Irena Berezovsky" <ire...@mellanox.com<mailto:ire...@mellanox.com>> wrote: Hi, As one of the next steps for PCI pass-through I would like to discuss is the support for PCI pass-through vNIC. While nova takes care of PCI pass-through device resources management and VIF settings, neutron should manage their networking configuration. I would like to register a summit proposal to discuss the support for PCI pass-through networking. I am not sure what would be the right topic to discuss the PCI pass-through networking, since it involve both nova and neutron. There is already a session registered by Yongli on nova topic to discuss the PCI pass-through next steps. I think PCI pass-through networking is quite a big topic and it worth to have a separate discussion. Is there any other people who are interested to discuss it and share their thoughts and experience? Regards, Irena
