<div>Ok, this is something that's going to be added in ml2. I was looking at the bind_port() routine in mech_agent.py. The routine check_segment_for_agent() seems to be performing static check. So we are going to add something like check_vnic_type_for_agent(),
I guess? Is the pairing of an agent with the mech driver predetermined? The routine bind_port() just throws warnings, though.</div>
<div><br>
</div>
<div>In any case, this is after the fact the scheduler has decided to place the VM onto the host. </div>
<div><br>
</div>
<div>Maybe not for now, but we need to consider how to support the hybrid compute nodes. Would an agent be able to support multiple vnic types? Or is it possible to reuse ovs agent, in the same time running another agent to support sriov? Any thoughts?</div>
