<div dir="ltr">Hi Gary, <div><br></div><div>No what I meant was since nova-api would be creating the ports for the requested networks in quantum (rather than when the instance lands on a nova compute node) that the api call to launch an instance to nova-api would take longer. That said there was some discussion around this in #openstack-nova and one thing that was discussed was possibly removing the creation of ports from nova and have something else orchestrate this process (similar to how we can currently do nova boot --nic port-id= ) </div>

I created the following blueprint and wanted to hear what the
community though before starting on it. <br>

In the BP you wrote: "The only downside I see of moving this logic
into nova-api is that we would slow down the response time from
nova-api to provision instances."<br>
<br>
This can be addressed by nova prefetching quantum ports. When nova
needs a port is can be retrieved from a cached pool. This may be a
way of addressing this at a later stage if the nova api is indeed a
bottleneck when it comes to the quantum interface (please note that
this currently happens on the compute node at the moment)<br>
<br>
Thanks<br>
