[openstack-dev] [Ironic] - Integration with neutron using external attachment point

Hello,

I am working on an extension for neutron to allow external attachment point
information to be stored and used by backend plugins/drivers to place
switch ports into neutron networks[1].

One of the primary use cases is to integrate ironic with neutron. The basic
workflow is that ironic will create the external attachment points when
servers are initially installed. This step could either be automated
(extract switch-ID and port number of LLDP message) or it could be manually
performed by an admin who notes the ports a server is plugged into.

Then when an instance is chosen for assignment and the neutron port needs
to be created, the creation request would reference the corresponding
attachment ID and neutron would configure the physical switch port to place
the port on the appropriate neutron network.

If this workflow won't work for Ironic, please respond to this email or
leave comments on the blueprint review.
