I'm with Bob on this, I think - I would expect that vnic_type is passed in by the user (user readable, and writeable, at least if the port is not attached) and then may need to be reflected back, if present, in the 'binding' attribute via the port binding extension (unless Nova can just go look for it - I'm not clear on what's possible here). [IrenaB] I would prefer not to add new extension for vnic_type. I think it fits well into port binding extension, and it may be reasonable to follow the policy rules as Robert suggested. The way user specifies the vnic_type via nova API is currently left out for short term. Based on previous PCI meeting discussions, it was raised by John that regular user may be required to set vNIC flavor, but he definitely not expected to manage 'driver' level details of the way to connect vNIC. For me it looks like neutron port can handle vnic_type via port binding, and the question is whether it is standalone attribute on port binding or a key,val pair on port binding:profile. Also, would a normal cloud user really know what pci_flavor to use? Isn't all this kind of detail hidden from a normal user within the nova VM flavor (or host aggregate or whatever) pre-configured by the admin? Flavors are user-visible, analogous to Nova's machine flavors, they're just not user editable. I'm not sure where port profiles come from. -- Ian.
