Open Stack

Thanks Yuiko for doing this, but I'm sorry that I can't go to Austin, so I
would like to add more details about my proposal here, hope someone can
bring it to the session.

Add a custom HTTP proxy for web based consoles to Nova
https://review.openstack.org/#/c/300582/

* Pros:
- for Ironic
      - Don't need any change to Ironic API
      - We can continue use the web interface from Ironic, don't rely on
Nova's websocketproxy to provide a ws/wss URL
- for Nova and Horizon
      - Support one more console type for hypervisors which provide web
based consoles not only for Ironic, here's another one which also needs it
        https://blueprints.launchpad.net/nova/+spec/spice-http-proxy

* Cons:
- Don't output log file
  but I think session logging capability is a great extension for
shellinabox, will explore this more.


And Ironic will support different console drivers, I don't think only one
proposal will be accepted here.
