<p class="MsoNormal"><span style="color:#1F497D">If I understand your question below, you are looking for a way to tie up between requested virtual network(s) and requested PCI device(s). The way we did it in our solution is to map a provider:physical_network
to an interface that represents the Physical Function. Every virtual network is bound to the provider:physical_network, so the PCI device should be allocated based on this mapping. We can map a PCI alias to the provider:physical_network.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Another topic to discuss is where the mapping between neutron port and PCI device should be managed. One way to solve it, is to propagate the allocated PCI device details to neutron on port creation.

<p class="MsoNormal"><span style="font-size:10.5pt;color:black;mso-fareast-language:ZH-CN">The end to end flow is actually encompassed in the blueprints in a nutshell. I will reiterate it in below. The binding between Nova and Neutron occurs with the neutron
v2 API that nova invokes in order to provision the neutron services. The vif driver is responsible for plugging in an instance onto the networking setup that neutron has created on the host.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;color:black;mso-fareast-language:ZH-CN">Normally, one will invoke "nova boot" api with the —nic options to specify the nic with which the instance will be connected to the network. It currently allows net-id,
fixed ip and/or port-id to be specified for the option. However, it doesn't allow one to specify special networking requirements for the instance. Thanks to the nova pci-passthrough work, one can specify PCI passthrough device(s) in the nova flavor. But it
doesn't provide means to tie up these PCI devices in the case of ethernet adpators with networking services. Therefore the idea is actually simple as indicated by the blueprint titles, to provide means to tie up SRIOV devices with neutron services. A work
flow would roughly look like this for 'nova boot':<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D;mso-fareast-language:ZH-CN">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.</span><span style="color:black;mso-fareast-language:ZH-CN"><o:p></o:p></span></p>

to a particular SRIOV technology. <o:p></o:p></span></p>
