<p class="MsoNormal"><span style="color:#1F497D">Hi Robert,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thank you very much for sharing the information regarding your efforts. Can you please share your idea of the end to end flow? How do you suggest to bind Nova and Neutron?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The blueprints you registered make sense. On Nova side, there is a need to bind between requested virtual network and PCI device/interface to be allocated as vNIC.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">On the Neutron side, there is a need to support networking configuration of the vNIC. Neutron should be able to identify the PCI device/macvtap interface in order to apply configuration. I think it makes sense
to provide neutron integration via dedicated Modular Layer 2 Mechanism Driver to allow PCI pass-through vNIC support along with other networking technologies.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">During the Havana Release, we introduced Mellanox Neutron plugin that enables networking via SRIOV pass-through devices or macvtap interfaces.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">We want to integrate our solution with PCI pass-through Nova support. I will be glad to share more details if you are interested.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The PCI pass-through networking support is planned to be discussed during the summit:
</span><a href="http://summit.openstack.org/cfp/details/129">http://summit.openstack.org/cfp/details/129</a>.
<span style="color:#1F497D">I think it’s worth to drill down into more detailed proposal and present it during the summit, especially since it impacts both nova and neutron projects.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Would you be interested in collaboration on this effort? Would you be interested to exchange more emails or set an IRC/WebEx meeting during this week before the summit?<o:p></o:p></span></p>

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 (<a href="https://blueprints.launchpad.net/nova/+spec/pci-passthrough-base" id="yui_3_10_3_1_1382711548329_391"><span style="font-size:9.0pt;font-family:"Arial","sans-serif";color:#0033AA;background:white;text-decoration:none">https://blueprints.launchpad.net/nova/+spec/pci-passthrough-base</span></a></span><span style="font-size:9.0pt;font-family:"Arial","sans-serif";color:#333333;background:white"> and<br>
