Comment 10 for bug 1172808

Hi,

Sorry to jump into this late.

Currently when you launch an instance nova-api queries quantum to see if the network uuid is in quantum. In my opinon, I think it makes sense for nova-api to do a port-create() rather than a get-networks()) to fail early rather than later as Phil brings up. I also agree that we don't want to make nova-api the bottle neck here. That said, it's doing a get_networks() anyways that we could change to a create_port() which would solve the issue.

My 2 cents.
