There's quite a bit to unpack here: are you suggesting that running these
services in HA configuration doesn't help either with the data plane being
gone after a stop/restart? Ultimately this boils down to where the state is
persisted, and while certain agents rely on namespaces and processes whose
ephemeral nature is hard to persist, enough could be done to allow for a
non-disruptive bumping of the afore mentioned services.

[openstack-dev] [neutron] cycle highlights for sub-projects

2018-02-02 Thread Armando M.
Hi neutrinos,

RC1 is fast approaching and this time we can add highlights to the release
files [1]. If I can ask you anyone interested in contributing to the
highlights: please review [2].

Miguel and I will make sure they are compiled correctly. We have time until
Feb 9 to get this done.

Many thanks,
Armando

It was intentional and was meant to help stabilize/sync up the core (of
neutron) with the subprojects. Without it it would be practically
impossible for a downstream consumer to figure out what works with which.
As a side effect, the lack of well thought out API versioning in Neutron
means we can't quite introduce breaking changes in the API and that means
we'll probably never bump the neutron-lib's major version.

This was done as part of the stadium effort [1,2]. The rationale being that
changes and/or new proposals for API definitions would be located in
neutron-lib (same for client extensions but in neutronclient) so that they
would be overseen by the neutron-drivers team to provide a level of
consistency across projects included in the stadium.

It'll still take two +2 to push a patch in, and the oversight from more
seasoned stable reviewers is still there to assist more inexperienced ones.
Aside from the occasional lag, I don't believe that backports linger as
much as they used to, but with the help of the dashboard and the initiative
of the individual project maintainers velocity should increase. To be
honest, I am not sure why we didn't do that before, similar review rights
apply to things like specs reviews and neutron-lib changes. As for your
concern about people stepping out of their own turf, I honestly don't
believe that's a problem in reality, and even if it was, I always encourage
people to reach out on IRC or other means.

I don't have admin rights to the neutron-stable-maint team, fo that someone
has to nudge Ihar :)

We had a Gerrit dashboard that helped stable reviewers stay on top of

Rather than create yet another group(s), it makes sense to have an
individual from each neutron project participate in the
neutron-stable-maint team (whose admin rights I think are held by Ihar as
neutron member), for those of whom have actually an interest in reviewing
stable patches :)

[openstack-dev] [neutron] Stepping down from core

2017-12-15 Thread Armando M.
Hi neutrinos,

To some of you this email may not come as a surprise.

During the past few months my upstream community engagements have been more
and more sporadic. While I tried hard to stay committed and fulfill my core
responsibilities I feel like I failed to retain the level of quality and
consistency that I would have liked ever since I stepped down from being
the Neutron PTL back at the end of Ocata.

I stated many times when talking to other core developers that being core
is a duty rather than a privilege, and I personally feel like it's way
overdue for me to recognize on the mailing list that it's the time that I
state officially my intention to step down due to other commitments.

This does not mean that I will disappear tomorrow. I'll continue to be on
neutron IRC channels, support the neutron team, being the release liasion
for Queens, participate at meetings, and be open to providing feedback to
anyone who thinks my opinion is still valuable, especially when dealing
with the neutron quirks for which I might be (git) blamed :)

Cheers,
Armando

Jeremy and I talked about this in [1].

To sum it up: the necessity of neutron for plugins is primarily for testing
and installation to the best of my knowledge. Other coupling tied to bash
scripts that control gate jobs could be easily addressed if it gets in the
way. Therefore, should we move away from tox for release specific tasks,
it's entirely possible to drop the custom project definition.

I hope I represented the conversation correctly!

the work on neutron-lib is slowly progressing but it's not close enough to
allow us to break the dependency that requires neutron sub-projects to add
neutron to the list of required-projects (which I believe the sort of the
error in the release pipeline stems from).

I tried it and it works like a charm, though I noticed some harmless side
effects in that changes [1] in my patch showed up unsolicited.

Is this strictly necessary? I don't see these in other gerrit ACLs
(irrespective of whether they are part of neutron or not). My understanding
is that the release can be fully managed by the openstack release team once
a patch like [1] is posted to the openstack/releases project.

[openstack-dev] [neutron] RC1 week

2017-08-07 Thread Armando M.
Hi neutrinos,

Today RC week starts [0] and I have prepared release patch [1]. For the
project you're liasion, please review the patch for accuracy and make sure
we tag RC1/create a stable branch with the git commit hash you are OK with.

Many thanks,
Armando

The switch to cycle-with-milestone [1] for all projects under neutron
governance (except neutron-lib and ovsdbapp that are libraries) was done
with the explicit intent of avoiding the overdue cut of stable branches for
the current release, which may lead to the exact problem that Tony stated
here.

I would recommend against the workaround of disabling them because of the
stated rationale.

Can you open a bug report, potentially when you're ready to file a fix (or
enable someone else to take ownership of the fix)? This way we can have a
more effective conversation either on the bug report or code review.

Thanks,
Armando

Is there any bug report that captures the actual error you're facing? Out
of the list of plugins that have been added to that list over time, most
work just exercising the core plugin API, and we can look into the ones
that don't to figure out whether we overlooked some design abstractions
during code review.

I think we're missing the the fundamental premise behind the introduction
of this map, which is that the addition of plugins to this list is done
only on the basis of the fact that the plugin being added introduces
functionality that's orthogonal to core plugins, and as such should work
with any, and not depend on internals of the core plugin implementation.

If something does break, it should be treated as a bug, rather than
allowing overloading this, because that's goes against the main rationale
for it being hard-coded.

Re: [openstack-dev] [nova][vlan trunking] Guest networking configuration for vlan trunk

There have been discussions in the past about this [1]. The conclusion of
the discussion was: Nova should have everything it needs to expose trunk
details to guest via the metadata API/config drive and at this stage
nothing is required from the neutron end (and hence there's no point in
filing a Neutron RFE).

While notifying trunk changes to nova require a simple minor enhancement in
neutron, it seems premature to go down that path when there's no nova
scaffolding yet. Someone should then figure out how the guest itself gets
notified of trunk changes so that it can rearrange its networking stack.
That might as well be left to some special sauce added to the guest image,
though no meaningful discussion has taken place on how to crack this
particular nut.

I think this is due the way external networks ended up being modeled in
neutron. I suppose we could have allowed the user to specify a subnet, so
long that it fell in the bucket of subnets that belong to a router:external
network.

Tricircle aims at coordinating independent neutron systems that exist in
separated openstack deployments. Making Neutron cell-aware will work in the
context of the same openstack deployment.

[openstack-dev] [neutron]

2017-05-12 Thread Armando M.
Hi folks,

At the summit we had a discussion on how to expand get-me-a-network [1]. A
few main points were collected during the session:

* Make get-me-a-network work with Horizon;
* Make get-me-a-network able to auto-assign floating IPs;
* Make get-me-a-network able to work with any network topology;
* Make get-me-a-network able to deal with NetworkAmbiguous error.

Link to bug reports [2,3,4,5] are below to move these forward on
Launchpad. Please,
do provide feedback in case I omitted some other key takeaway.

Thanks,

[openstack-dev] [neutron] diagnostics

2017-05-12 Thread Armando M.
Hi folks,

At the summit we had a forum session [1] to gather feedback on the current
diagnostics proposal [2] and help the neutron developer team drive the
first implementation of the API proposal.

Two main points were brought for discussion:

1) which diagnostics checks to provide to start with;
2) how to implement such checks.

Reachability seems to be on the top of the list, ie. the ability to
establish connectivity between two endpoints. The other one was to be
friendly to operators, in that they may not necessarily want to write
python code in order to add more checks to the platform. The idea is to
define on a set of variables to be exposed to the check function and let
this be written in any language of choice.

Please, do provide feedback in case I omitted some other key takeaway.

Thanks,
Armando

2017-05-12 Thread Armando M.
Hi folks,

At the summit we had a discussion on how to deploy a single neutron system
across multiple geographical sites [1]. You can find notes of the
discussion on [2].

One key requirement that came from the discussion was to make Neutron more
Nova cells friendly. I filed an RFE bug [3] so that we can move this
forward on Lauchpad.

Please, do provide feedback in case I omitted some other key takeaway.

Thanks,

Historically this was called l2gw agent (node). You can find references in

The l2gw agent uses solely OVSDB to interact to the server and as such it
can run anywhere. In fact, in Arista's POC video [3] (credit to Sukhdev),
the demo setup shows this in more details.

I am not aware of any effort to implement L2GW purely in software, in fact
this was one key missing pieces that prevented the project to have CI
solely dealt with the upstream infra resources. Perhaps OVN may come to the
rescue here, I recall at some point the team was looking at the L2GW API.

There's no written rule to prefix tables with formal labels. IMO it would
largely fail as a rule in practice even if we wrote one down. Have you
considered taking a backup of your DB prior to the migration so that you
can restore from it?

[openstack-dev] [neutron] networking-ofagent officially

2017-03-03 Thread Armando M.
Hi neutrinos,

As stated a while back [1], it's about time to pull the trigger on the
retirement of networking-ofagent. Please find the retirement patches
available at [2]. Users of this repo must use the neutron OVS agent with
of_interface set to native to retain the same level of capability.

Cheers,
Armando

[openstack-dev] [neutron] Ocata postmortem

2017-02-23 Thread Armando M.
Hi folks,

Now that Ocata is officially releases, I'd like to get a moment of your
time to double check our postmortem document [1], and provide as much
information as you can on the state of work assigned to you or work you
have been involved with during the Ocata timeframe.

Your old PTL and consumers/watchers of our project will be immensely
grateful.

Cheers,
Armando

I am pretty sure it wasn't our intentions to 'kill' your ideas, but
otherwise set you on the right path for fixing the bug. I still believe
that a complete and robust L3 HA solution cannot be built solely with
Neutron alone, and that's what I was trying to say with the comment
referenced below.

I had a look at this one but I am baffled by some of the log outputs.
Requests for spawning faulty instances never make to nova-compute service,
but there's no clear smoking gun as to why this happens. I was looking for
oom-kills, but there was no sign of it either.

Hi neutrinos,

I did not hear anything back from the liaisons of the above mentioned
project over the past few days. Can you clarify your plans for cutting an
Ocata release?

Thanks,
Armando

[openstack-dev] [neutron] [stadium] subprojects on independent release cycle

2017-02-02 Thread Armando M.
Hi neutrinos,

I have put a number of patches in the merge queue for a few sub-projects.
We currently have a number of these that are on an independent release
schedule. In particular:

   - networking-bagpipe
   - networking-bgpvpn
   - networking-midonet
   - networking-odl
   - networking-sfc

Please make sure that between now and March 10th [1], you work to prepare
at least one ocata release that works with neutron's [2] and cut a stable
branch before than. That would incredibly help consumers who are interested
in assembling these bits together and start testing ocata as soon as it's
out.

Your collaboration is much appreciated.

Many thanks,
Armando

Hi,

With the release coming up, it's best to spend the time to polish what we
have.

Sorry for the short notice.

Thanks,

Not sure I agree on this one, this has been observed multiple times in the
gate already [1] (though I am not sure there's a bug for it), and I don't
believe it has anything to do with the number of API workers, unless not
even two workers are enough.

I must admit I share your fear, but out of the tests that I have executed
so far in [1,2,3], the house didn't burn in a fire. I am looking for other
ways to have a substantial memory saving with a relatively quick and dirty
fix, but coming up empty handed thus far.

For the time being, and to provide relief to the gate, should we want to
lock the API_WORKERS to 1? I'll post something for review and see how many
people shoot it down :)

Thanks for your feedback!

[openstack-dev] [neutron] [release] misleading release notes

2017-02-01 Thread Armando M.
Hi,

There is something puzzling about release notes. I don't see 8.0.0 [1], and
it looks like features released in Mitaka are being advertised as Newton
features [2]. For instance, [3] 'Agent availability zones' shows as a
Newton feature when I am pretty positive that it went in Mitaka [4].

I suspect what happens is that someone revises the content at a later date
and reno associated the last timestamp of the release note with release
where the change has been made?

I don't see other projects' release notes broken this way so we must be
doing something wrong. It would be good to have guidance from the release
team.

Thanks,
Armando

[openstack-dev] [infra] [gate] [all] openstack services footprint lead to oom-kill in the gate

2017-02-01 Thread Armando M.
Hi,

[TL;DR]: OpenStack services have steadily increased their memory
footprints. We need a concerted way to address the oom-kills experienced in
the openstack gate, as we may have reached a ceiling.

Now the longer version:


We have been experiencing some instability in the gate lately due to a
number of reasons. When everything adds up, this means it's rather
difficult to merge anything and knowing we're in feature freeze, that adds
to stress. One culprit was identified to be [1].

We initially tried to increase the swappiness, but that didn't seem to
help. Then we have looked at the resident memory in use. When going back
over the past three releases we have noticed that the aggregated memory
footprint of some openstack projects has grown steadily. We have the
following:

   - Mitaka
  - neutron: 1.40GB
  - nova: 1.70GB
  - swift: 640MB
  - cinder: 730MB
  - keystone: 760MB
  - horizon: 17MB
  - glance: 538MB
   - Newton
   - neutron: 1.59GB (+13%)
  - nova: 1.67GB (-1%)
  - swift: 779MB (+21%)
  - cinder: 878MB (+20%)
  - keystone: 919MB (+20%)
  - horizon: 21MB (+23%)
  - glance: 721MB (+34%)
   - Ocata
  - neutron: 1.75GB (+10%)
  - nova: 1.95GB (%16%)
  - swift: 703MB (-9%)
  - cinder: 920MB (4%)
  - keystone: 903MB (-1%)
  - horizon: 25MB (+20%)
  - glance: 740MB (+2%)

Numbers are approximated and I only took a couple of samples, but in a
nutshell, the majority of the services have seen double digit growth over
the past two cycles in terms of the amount or RSS memory they use.

Since [1] is observed only since ocata [2], I imagine that's pretty
reasonable to assume that memory increase might as well be a determining
factor to the oom-kills we see in the gate.

Profiling and surgically reducing the memory used by each component in each
service is a lengthy process, but I'd rather see some gate relief right
away. Reducing the number of API workers helps bring the RSS memory down
back to mitaka levels:

   - neutron: 1.54GB
   - nova: 1.24GB
   - swift: 694MB
   - cinder: 778MB
   - keystone: 891MB
   - horizon: 24MB
   - glance: 490MB

However, it may have other side effects, like longer execution times, or
increase of timeouts.

Where do we go from here? I am not particularly fond of stop-gap [4], but
it is the one fix that most widely address the memory increase we have
experienced across the board.

Thanks,
Armando

Let's stop merging until the bot proposal change lands. That ought to stop
the spurious rebase!

[openstack-dev] [neutron] Neutron CI team meeting

2017-01-31 Thread Armando M.
Hi folks,

Recently [1], a new meeting has been setup to give the neutron team a
dedicated time to discuss any upstream CI matter (gate issues, testing
strategies, etc), as well as an overflow space to be used after the main
team meeting section [3]. Kudos to Ihar for being our first chair.

Needless to say, attendance is welcome.

Cheers,

Dasm, thanks for the details provided. Let me also add that:

You can find milestone deliverables at [1].

Between now and the official release date (week of Feb 20th, calendar [2]
for more details), we will be busy with the following:

   - cleaning up release notes [3]
   - handling release tasks [4]
   - squashing doc bugs [5]
   - dealing with gate failures [6]
   - apply for FFE on the ocata postmortem [7]
   - for pending efforts that get a FFE granted, there's time until we cut
   an RC1 [8]
   - Pike-1 opens up as soon as RC1 is cut [9] (which I took the liberty to
   seed based on reasonable expectations of the progress we can make on
   outstanding efforts)
   - if you find a RC critical bug, please file it and add bug tag
   'ocata-rc-potential' [10]
   - If you are a subproject maintainer, please check [11], switch to
   release mindset and get ready to prepare an Ocata release.

Be mindful of what you approve for merge (e.g. patches containing DB
migration need special attention), and double check whether it's aimed at
making RC1 solid/complete. If not, please refrain from putting it in the
gate queue, and most of all, *recheck* mindfully.

Many thanks for your help, and when in doubt, reach out!

Cheers,
Armando

Even though I am not the one running, I am replying here because I feel
compelled as outgoing PTL and member of the core team to help the soon PTL
elect through this process.

In my opinion, the first thing to address is to lay down the foundations
for an objective comparison across drivers. The neutron team is obviously
best position in doing that. This was started with how we chose to organize
the neutron project, what quality criteria mattered for the team, and how
qualifying neutron features can be tracked across releases (e.g. still work
in progress in [1]).

Only after we have these solid foundations in place, we can go about the
effort of tracking the wider ecosystem of neutron plugins, and identify who
is best positioned to keep that snapshot accurate over time.

Hi neutrinos,

No, it's not what you might be thinking...I am just delighted to see two
excellent candidates willing to take the reins of the project going forward
[1,2].

I couldn't hope for more enthusiasm; best of luck to both candidates and

Hi Bruno,

That's great to hear. If you have dev resources who are ready to jump in
Gerrit, please point me to their IRCs and Gerrit accounts and I am happy to
engage with them directly. Yamamoto and I have still core rights on the
repo and work on pushing fixes on an occasional basis. Once your devs feel
more confident, we can definitely talk about adding them to the
neutron-vpnaas core team.

My suggestion is to focus on the technical aspect of things before worrying
about the governance change. Those typically can happen only in certain
time windows of the release and with the Ocata release approaching feature
freeze, we definitely need to postpone the governance discussion until Pike
opens up.

Thanks,
Armando (irc:armax)

If you are referring to [1], I wouldn't expect anything less, it's the
OpenStack networking guide after all.

Problem statement from the user's point of view is typically left to the
specs [2,3].
I am sure one can argue that the content there may not be well written or
organized, but it was enough for getting the nova and the neutron team to
have a mutual understanding and agreement on how to design, implement and
test the feature.

>From what I hear, there is a gap in the networking guide in that the

I'd be happy to improve the docs, but your feedback is not very actionable.
Any chance you can elaborate on what you're struggling with?

Answering your question in a nutshell is very hard, but I'll try
nonetheless.

I bet that if you think really hard, complications may arise even when
dealing with images and compute resources. That's because, in the most
trivial cases you are not thinking about the services that your image must
provide (and if so you may start injecting user-data into your boot phase)
or performance requirements you may have (and if so, you may want your
hypervisors to provide certain optimizations).

IMO, the networking case is inherently complex because the network
architecture required by a non trivial application is itself complex, in
that you may need tiers of security, you need to HA, etc. In the most
trivial case where you just want a single endpoint to which you can talk
to, there's get-me-a-network [1,2]. You can fire boot a VM on of top of a
auto-provisioned network topology and off you go. To get external access
you're only left with a floating IP association, but that's only one API
call away.

Cheers,
Armando

[openstack-dev] [neutron] Neutron Pike PTG

2017-01-12 Thread Armando M.
Hi neutrinos,

The time for the PTG is approaching and if you are wondering about topics
and various agenda arrangements, you should consider the PTG more like a
mid-cycle on steroids: each project will be working on its own agenda,
usually via etherpads, and publish updates over the ML, up until and during
the week of the PTG.

Therefore, do not expect any published agenda, beyond a daily map of where
teams will be gathering in which rooms. We also need to work out on how to
arrange cross-projects conversations. Please expect to learn more from the
team organizers.

For now, please start collecting ideas on [2]. Once we got critical mass on
[2], I'll work with the drivers team to finalize and sanitize a more formal
agenda, which will then be published on a new etherpad (TBD). For those who
cannot participate in person to the event, we will provide a mid-cycle
report.

Cheers,
Armando

[openstack-dev] [neutron] PTL nominations deadline and non-candidacy

2017-01-09 Thread Armando M.
Hi neutrinos,

The PTL nomination week is fast approaching [0], and as you might have
guessed by the subject of this email, I am not planning to run for Pike. If
I look back at [1], I would like to think that I was able to exercise the
influence on the goals I set out with my first self-nomination [2].

That said, when it comes to a dynamic project like neutron one can't never
claim to be *done done* and for this reason, I will continue to be part of
the neutron core team, and help the future PTL drive the next stage of the
project's journey.

I must admit, I don't write this email lightly, however I feel that it is
now the right moment for me to step down, and give someone else the
opportunity to grow in the amazing role of neutron PTL! I have certainly
loved every minute of it!

Cheers,
Armando

[openstack-dev] [neutron] multinode CI jobs in the gate

2016-12-15 Thread Armando M.
Hi Neutrinos,

Infra patch proposed in [1] got me thinking again about what we shall do
when it comes to multinode testing in the gate and how to focus our testing
and CI efforts upstream going forward. My line of thinking has always been
that multinode resources should be devoted to configurations whose coverage
fully benefit from the inherent nature of the distributed deployment, and
that means giving priority to DVR+HA and demote other configurations that
use centralized routing.

I know that some of you in team have worked on this, but I am a bit behind
on the latest status update. Any good soul willing to bring a strapped (for
time) PTL up to speed?

[openstack-dev] [neutron] proposing Ryan Tidwell and Nate Johnston as service LTs

 Hi neutrinos,

I would like to propose Ryan and Nate as the go-to fellows for
service-related patches.

Both are core in their repos of focus, namely neutron-dynamic-routing and
neutron-fwaas, and have a good understanding of the service framework, the
agent framework and other bits and pieces. At this point, entrusting them
with the responsibility is almost a formality.

Hi neutrinos,

Miguel Lavalle has been driving the project forward consistently and
reliably. I would like to propose him to be entrusted with +2/+A rights in
the areas he's been most prolific, which are L3 and DHCP.

At the same time, I'd like to propose Brian Haley as our next Chief L3
Officer. Both of them have worked with Carl Baldwin extensively and that
can only be a guarantee of quality.

Abhishek Raut's recent involvement in OSC and python-neutronclient has

This not only will help speed up our transition to OSC CLI, but also

Follow up: Kevin and I put together a couple of patches [1,2] to fix and
validate how to speed up the lookup. We'll dig into why sqlalchemy is
acting differently when listing ports with or without filters, but this
should do for now.

I looked into [1] a little bit as it bothered me :)

Here's my findings:


   - openstack port list is slower than neutron port-list as it looks like
   the command goes to Nova first [2], which is where the overhead comes from.
   - when you have subports the port-list response gets bigger because of
   the bigger response due to the trunk-details extension.
   - However, the bulk of the time is spent in [3], when building the
   payload for a port involved as a parent port. In no other case you will see
   the overhead as in no other case the loop over subports is executed.

The hook should be optimized!

Armando

Ah, I was actually going to add the following:

Whether segmentation type and segmentation ID are mandatory or not depends
on the driver in charge of the trunk. This is because for use cases like
Ironic, as you wonder, these details may be inferred by the underlying
network, as you point out.

However, we have not tackled the Ironic use case just yet, for the main
reason that ironic spec [1] is still WIP. So as far as newton is concerned,
Ironic is not on the list of supported use cases for vlan-aware-vms, yet
[2]. The reason why we have not tackled it yet is that there's the
'nuisance' in that a specific driver is known to the trunk plugin only at
the time a parent port is bound and we hadn't come up with a clean and
elegant way to developer a validator that took into account of it. I'll
file a bug report to make sure this won't fall through the cracks. It'll be
tagged with 'trunk'.

Segmentation type and ID are used to multiplex/demultiplex traffic in/out
of the guest associated to a particular trunk. Aside the fact that the only
supported type is VLAN at the moment (if ever), the IDs are user provided
to uniquely identify the traffic coming in/out of the trunked networks so
that it can reach the appropriate vlan interface within the guest. The
documentation [1] is still in flight, but it clarifies this point.

Bence,

Thanks for the wealth of information provided, I was looking forward to it!
The results of the experimentation campaign makes me somewhat confident
that trunk feature design is solid, or at least that is what it looks like!
I'll look into why there is a penalty on port-list, because that's
surprising for me too.

I also know that the QE team internally at HPE has done some perf testing
(though I don't have results publicly available yet), but what I can share
at this point is:

   - They also disabled l2pop to push the boundaries of trunk deployments;
   - They disabled OVS firewall (though for reasons orthogonal to
   scalability limits introduced by the functionality);
   - They flipped back to ovsctl interface, as it turned out to be one of
   components that introduced some *penalty*. Since you use native
   interface, it'd be nice to see what happens if you flipped this switch too;
   - RPC timeout of 300.

On a testbed of 3 controllers and 7 computes, this is at high level what
they found out the following:

   - 100 trunks, with 1900 subports took about 30 mins with no errors;
   - 500 subports take about 1 min to bind to a trunk;
   - Booting a VM on trunk with 100 subports takes as little as 15 seconds
   to successful ping. Trunk goes from BUILD -> ACTIVE within 60 seconds of
   booting the VM;
   - Scaling to 700 VM's incrementally on trunks with 100 initial subports
   is constant (e.g. booting time stays set at ~15 seconds).

I believe Ryan Tidwell may have more on this.

Cheers,
Armando

This is actually a good point worth emphasising because this might have
been unique to our situation at the time: there was an infra patch applied
to all neutron stadium projects that modified gerrit ACLs so that stable
backports would be under the control of the neutron-stable-main team.

Because of the example that Kevin described, members of the team were faced
with the paradox of having to either turn a blind eye, or try to fight the
battle of educating contributors and fixing the 'malpractice' at the root.
Now irrespective of whether the openstack stable policy is deemed too rigid
by some or not, we started to observe that within the same governance we
had individual initiatives behaving totally differently, so differently
that some of us started to wonder what the stadium was for, what was the
point of it, and whether it was misused as a marketing tool.

That's when I came up with the proposal of defining the neutron stadium as
a list of projects that behave consistently and adhere to a common set of
agreed principles, such as common backporting strategies, testing
procedures, including our ability to claim the entire technology stack to
be fully open and completely exercised with upstream infra resources: a
list of projects that any member of the neutron core team should be able to
stand behind and support it without too many ideological clashes.

It's been a long journey and we're almost at the end of it. The neutron
core team has been very supportive of this journey. Now I am not sure
whether they did that just to make me happy and will undo all of it when I
step down :) but I genuinely think it has been a great effort that allowed
us to improve what we've been building by means of setting ourselves
achievable and measurable goals.

In a nutshell: scalability. The list became huge, the core team was made in
charge of dealing with releases requests, backport requests, infra,
governance and doc changes etc. Any of those changes required a neutron
liasion vouching for them. This became untenable, distracting and defeating
the whole point of breaking down the monolithic codebase we were trying to
move away from. I (the PTL since Mitaka) personally felt that we needed to
empower the individual efforts to be in charge or their own destiny and at
the same time making sure that the neutron project as described by the
governance repo was cohesive and made sense to the eye of someone looking
at the project list.

If the eviction or exclusion of a driver caused a project and its
contributors lose their ATC status, access to horizontal teams services
(e.g. representation on docs.o.o, release.o.o), etc, I always thought that
was wrong; that should have not happened, and I hope this effort led by
Doug can fix that.

The neutron team cares about drivers, and I personally believe that are
very important to the success of the OpenStack community. That's why we
enabled the innovation by breaking them out and keeping/augmenting the
extension points provided by the core platform so that they are not stifled
by the chokepoint that the core team may represent. At the same time, I
care about quality and consistency, and I want to be proudly standing
behind the stuff I am involved in, and as such I don't want to be
erroneously associated with initiatives I (and the core team) cannot ever
have the bandwidth to deal with.

[openstack-dev] [neutron] core and driver teams attrition

2016-12-01 Thread Armando M.
Hi Neutrinos,

By now a few of us have noticed that the neutron core and driver teams have
lost a number of very talented and experienced engineers: well...this sucks
there's no more polite way to put it!!

These engineers are the collective memory of the project, know the kinks
and gotchas of the codebase, and are very intimate with the overall
openstack machine. They leave a big void behind. It sad to see them go, but
personally I have the utmost confidence in the fact that they have groomed
other engineers to step up in a role of greater responsibility.

Ocata might be seen by some as a hiatus, and that's ok: take the time to
rest if you can, because the team is going to grow back stronger than ever,
and it will make neutron kick-ass, even more so than it already is.

You can count on it.

Happy hacking!
Armando

At the same time, I'll be working to make sure we have a coordinated access
to lbaas backports (i.e. tweaking gerrit ACLs).

I did file bug [1]. FWIW, vpnaas on strongswan works fine in xenial [2],
and if the rally teams feel like not losing vpnaas coverage, they could
switch to strongswan.

That's great to hear Yamamoto. Since you are already a neutron-core I
assume you are already intimate with the work required to strengthen the
VPNaaS project. I have added you to [4] and you can lean on me for any
changes that needs reviewing.

[openstack-dev] [neutron][octavia] Neutron LBaaS governance change and Octavia to the big tent

2016-11-30 Thread Armando M.
Hi folks,

A few hours ago a governance change [1] has been approved by TC members.
This means that from now on, the efforts for Load Balancing as a Service
efforts rest officially in the hands of the Octavia PTL and the Octavia
core team.

I will work with the help of the respective core teams to implement a
smooth transition. My suggestion at this point is for any ML communication
that pertain LBaaS issues to include [octavia] tag on the email subject.

Please do not hesitate to reach out for any questions and/or clarifications.

Cheers,
Armando
