Open Stack

Hi all,

I'm working with Tien who is a submitter of one[1] of console specs.
I joined the console session in Austin.

In the session, we got the following consensus.
- focus on serial console in Newton
- use nova-serial proxy as is

We also got some requirements[2] for this feature in the session.
We have started cooperating with Akira and Yuiko who submitted another similar spec[3].
We're going to unite our specs and add solutions for the requirements ASAP.

[1] ironic-ipmiproxy: https://review.openstack.org/#/c/296869/
[2] https://etherpad.openstack.org/p/ironic-newton-summit-console
[3] ironic-console-server: https://review.openstack.org/#/c/306755/

Thanks,
Hironori Shiina
