Re: [openstack-dev] [nova][CI] nova-networking or neutron netwokring for CI

2014-10-29 Thread Andreas Scheuring
Thanks for the feedback. 

OK, got it, nova networking is not a requirement for a CI. Then I'll see
not a single reason to support it. We will investigate in the neutron
way for our CI and also for production.

Now coming back to the Hypervisorsupportmatrix
( https://wiki.openstack.org/wiki/HypervisorSupportMatrix ). 
I guess the scope of this matrix is only nova and not neutron,cinder,..
isn't it? 

So in this matrix I have to tick the networking lines (vlan, routing,..)
as NOT supported, right? (as scope is neutron-networking, altough we
would support it with neutron).

Thanks, 
Andreas

 Agreed, neutron should be considered required for all of the reasons

I wouldn't go so far as to say there is no reason to support
nova-networking in your CI system, and we are working on deprecating it. It
hasn't been deprecated yet. Ideally you could test both neutron and
nova-network, but if you had to choose one it should be neutron.

Correct, if you don' support nova-network at all, then you should have an
'X' in those boxes.



 Thanks,
 Andreas

[openstack-dev] [nova][CI] nova-networking or neutron netwokring for CI

2014-10-28 Thread Andreas Scheuring
Hi, 
we're preparing to add a new platform, libvirt-kvm on system z
(https://blueprints.launchpad.net/nova/+spec/libvirt-kvm-systemz), to
the HypervisorSupportMatrix
https://wiki.openstack.org/wiki/HypervisorSupportMatrix .


This matrix also lists a number of networking features (e.g. vlan
networking, routing,..). 

If I interpret the footnotes correctly, these network items refer only
to nova-networking, right? So if I plan to support vlan networking with
neutron, but not with nova-networking it would be an x in the related
cell, right?


Now thinking one step further in the direction of a CI system for the
new platform. 

Are current nova CI platforms configured with nova-networking or with
neutron networking? Or is networking in general not even a part of the
nova CI approach?


My current assumption is that any networking is a requirement and most
of the systems would go with nova-networking. Is this true?

If so, does it make sense to run the CI system with neutron networking
instead of nova-networking? What's the best practice in this area?

Not sure about the deprecation plans of nova-networking. But setting up
the CI environment might also take a while. Do you think it's still
worthwhile spending time for the nova-network integration in the CI
system, if it might be deprecated in the future anyhow? 


Any input?

Thanks a lot!

Given we're moving towards deprecating nova-network in Kilo, if you
had to choose I'd say to use neutron here. But I'd like to hear what
other folks running CI systems for nova are doing as well, and also
what Michael has to say here.

Thanks,
Kyle

 Thanks a lot!
