Bug Description

Hi all,

Description
===========

I am running newton on centos7 and have currently one active instance. This instance is connected to two vxlan networks(int and vxlannetwork) and I would like to get it connected to two additonal, vlan and gre. Networks are created, but after I create the port and try to attach the interface I get an error. See below.

Steps to reproduce
===================

# nova list
+--------------------------------------+--------+--------+------------+-------------+---------------------------------------+
| ID | Name | Status | Task State | Power State | Networks |
+--------------------------------------+--------+--------+------------+-------------+---------------------------------------+
| 354caa3d-bddb-4396-ac0a-ef12e06b14e3 | cirros | ACTIVE | - | Running | int=10.0.0.5; vxlannetwork=10.0.10.12 |
+--------------------------------------+--------+--------+------------+-------------+---------------------------------------+

when I create a port on vlan network and try to attach I get the following error

Expected result
===============

Expected results would be to attach the additional networks, vlan and gre to instance.

Environment
===========

The error:

Failed to bind port 2795d640-adfe-417e-a598-68b7336b19fa on host cl310openstack.lab.local for vnic_type normal using segments [{'segmentation_id': 35, 'physical_network': u'physnet1', 'id': u'6b180747-3063-480b-b752-af94a67ca7f5', 'network_type': u'vlan'}

May be the result of an incompatible configuration. The ID 6b180747-3063-480b-b752-af94a67ca7f5 is it accessible to the end-user?

The compute API should at least handle the PortBindingFailed error and not produce a 500 to the user, it's more likely a 400 error.

On the other hand, nova really has no idea why the port binding failed, we don't know if it's a bad request or an actual failure on the networking backend.
