[openstack-dev] [all][ptg][os-upstream-institute] Poll on Interest in Upstream Institute at PTGs

[Jay S Bryant]

All,

I saw that there was some interest indicated in the feedback session 
with regards to having an OpenStack Upstream Institute session at 
Project Team Gatherings.  For those who are not familiar with the 
OpenStack Upstream Institute (OUI), it is a one to one and a half day 
education session designed to help people who are new to OpenStack to 
get started contributing to the community.  The detailed contents of the 
training may be seen on the OUI docs site.  [1]


A poll has been created [2] to understand how many people would have 
been interested in having the education at the Queens PTG in Denver and 
to also gauge the level of interest in having education at the Rocky PTG 
in Dublin.


The poll should only take a minute to complete and your time to share 
this information is greatly appreciated.  If you have any questions or 
concerns, feel free to ping me on IRC (jungleboyj) or via e-mail 
(jsbry...@electronicjungle.net).


Thanks!

Jay Bryant

[Ildiko Vancsa]

Hi Training Team,

I hope all of you who attended the PTG had a good time and got home safe.

I’m out of timezone this week therefore this week’s meeting is cancelled.

As a reminder, we have upcoming training occasions in London (Sept. 26), 
Copenhagen (Oct. 18) and Sydney (Nov. 4-5). Please sign up on the staff wiki 
page if you can come and help out on any of these events: 
https://wiki.openstack.org/wiki/OpenStack_Upstream_Institute_Occasions

And also keep an eye on the open reviews: 
https://review.openstack.org/#/q/project:openstack/training-guides+status:open

Re: [openstack-dev] [all] review.openstack.org downtime and Gerrit upgrade TODAY 15:00 UTC - 23:59 UTC

This work was functionally completed at 23:43 UTC. We are now running
Gerrit 2.13.9. There are some cleanup steps that need to be performed in
Infra land, mostly to get puppet running properly again.

You will also notice that newer Gerrit behaves in some new and exciting
ways. Most of these should be improvements like not needing to reapprove
changes that already have a +1 Workflow but also have a +1 Verified;
recheck should now work for these cases. If you find a new behavior that
looks like a bug please let us know, but we should also work to file
them upstream so that newer Gerrit can address them.

Feel free to ask us questions if anything else comes up.

Thank you to everyone that helped with the upgrade. Seems like these get
more and more difficult with each Gerrit release so all the help is
greatly appreciated.

Clark

[openstack-dev] [tripleo] Blueprints for Queens

[Alex Schultz]

Hey folks,

At the end of the PTG we did some work to triage the blueprints for
TripleO. The goal was to ensure that some of the items we talked about
were properly captured for the Queens cycle.  Please take a look at
the blueprints targeted towards queens[0] and update them with a
reasonable milestone for delivery (queens-1/queens-2 ideally).  If you
need to add additional blueprints, please triage appropriately.  I
will be using this list for tracking completion of features during
this cycle and reaching out the the assignee on the blueprints for
status.  Please make sure there is an assignee for your blueprint(s).

In addition to the Queens blueprints, we also created a future target
that can be used for tracking future efforts or things that won't be
worked on during the Queens cycle. It would be advisable to review
this list[1] and make sure we did not accidentally move out work that
will be completed in Queens.  The same goes for the Pike list[2] to
make sure they have all been properly updated to reflect that they
have been implemented or need to be moved.

Thanks,
-Alex

[openstack-dev] [nova] Queens PTG recap - everything else

[Matt Riedemann]

There was a whole lot of other stuff discussed at the PTG. The details 
are in [1]. I won't go into everything here, so I'm just highlighting 
some of the more concrete items that had owners or TODOs.


Ironic
--

The Ironic team came over on Wednesday afternoon. We talked a bit, had 
some laughs, it was a good time. Since I don't speak fluent baremetal, 
Dmitry Tantsur is going to recap those discussions in the mailing list. 
Thanks again, Dmitry.


Privsep
---

Michael Still has been going hog wild converting the nova libvirt driver 
code to use privsep instead of rootwrap. He has a series of changes 
tracked under this blueprint [2]. Most of the discussion was a refresh 
on privsep and a recap of what's already been merged and some discussion 
on outstanding patches. The goal for Queens is to get the entire libvirt 
driver converted and also try to get all of nova-compute converted, but 
we want to limit that to getting things merged early in the release to 
flush out bugs since a lot of these are weird, possibly untested code 
paths. There was also discussion of a kind of privsep heartbeat daemon 
to tell if it's running (even though it's not a separate service) but 
this is complicated and is not something we'll pursue for Queens.


Websockify security proxy framework
---

This is a long-standing security hardening feature [3] which has changed 
hands a few times and hasn't gotten much review. Sean Dague and Melanie 
Witt agreed to focus on reviewing this for Queens.


Certificate validation
--

This is another item that's been discussed since at least the Ocata 
summit but hasn't made much progress. Sean Dague agreed to help review 
this, and Eric Fried said he knew someone that could help review the 
security aspects of this change. Sean also suggested scheduling a 
hangout so the John Hopkins University team working on this can give a 
primer on the feature and what to look out for during review. We also 
suggested getting a scenario test written for this in the barbican 
tempest plugin, which runs as an experimental queue job for nova.


Notifications
-

Given the state of the Searchlight project and how we don't plan on 
using Searchlight as a global proxy for the compute REST API, we are not 
going to work on parity with versioned notifications there. There are 
some cleanups we still need to do in Nova for versioned notifications 
from a performance perspective. We also agreed that we aren't going to 
consider deprecating legacy unversioned notifications until we have 
parity with the versioned notifications, especially given legacy 
unversioned notification consumers have not yet moved to using the 
versioned notifications.


vGPU support


This depends on nested resource providers (like lots of other things). 
It was not clear from the discussion if this is static or dynamic 
support, e.g. can we hot plug vGPUs using Cyborg? I assume we will not 
support hot plugging at first. We also need improved functional testing 
of this space before we can make big changes.


Preemptible (spot) instances
-

This was continuing the discussion from the Boston forum session [5]. 
The major issue in Nova is that we don't want Nova to be in charge of 
orchestrating preempting instances when a request comes in for a "paid" 
instance. We agreed to start small where you can't burst over quota. 
Blazar also delivered some reservation features in Pike [6] which sound 
like they can be built on here, which also sound like expiration 
policies. Someone will have to prototype an external (to nova) "reaper" 
which will cull the preemptible instances based on some configurable 
policy. Honestly the notes here are confusing so we're going to need 
someone to drive this forward. That might mean picking up John Garbutt's 
draft spec for this (link not available right now).


Driver updates
--

Various teams from IBM gave updates on plans for their drivers in Queens.

PowerVM (in tree): the team is proposing a few more capabilities to the 
driver in Queens. Details are in the spec [7].


zDPM (out of tree): this out of tree driver has had two releases (ocata 
and pike) and is working on 3rd party CI. One issue they have with 
Tempest is they can only boot from volume.


zVM (out of tree): the team is working on refactoring some code into a 
library, similar to os-xenapi, os-powervm and oslo.vmware. They have CI 
running but are not yet reporting against nova changes.


Endpoint discovery
--

This is carry-over work from Ocata and Pike to standardize how Nova does 
endpoint discovery with other services, like 
keystone/placement/cinder/glance/neutron/ironic/barbican. The spec is 
here [8]. The dependent keystoneauth1 changes were released in Pike so 
we should be able to make quick progress on this early in Queens to 
flush out bugs.


Documentation
-

We talked about the r

I think we're actually mostly ok here. The one rule that looks off is the
one that I think you may have thought was correct... create_trust. I
updated the bug with reasoning. Please take a look and comment if I've
missed something or you've got further questions. Specific examples that
you've tried and got unexpected results would provide useful talking
points. Thanks!

Sorry, I think I caused this by adding them to the cinder-ci group in an
attempt to get them to stop showing up even when Filter CI was toggled. I
noticed that this morning and had removed them again before the gerrit down
time. It should not show up anymore.

Although I still need to remember how they need to be registered to get them
out of the filtered comments.

I noticed this when we switched over to using cryptography. I think at the time
the consensus was - meh. IIRC, it's an issue that we use an older version of
pypy. If system packages are available for a newer version, it probably would
be good to test that. But I have never seen pypy use in the wild, so I'm not
sure if it would be worth the effort.

Maybe easier just declaring pypy unsupported for service projects?

Hi Chris,

Sorry I missed the meeting since I was not in PTG last week. After a quick

I think this is a great initiative.  It would be nice to share some of
the TripleO experience in containerized deployments so that we can use
Puppet for containerized deployments.  Perhaps we can work together on
adding some classes which can help deploy and configure containerized
services with Puppet.

[openstack-dev] [tripleo] Making containerized service deployment the default

[Alex Schultz]

Hey ops & devs,

We talked about containers extensively at the PTG and one of the items
that needs to be addressed is that currently we still deploy the
services as bare metal services via puppet. For Queens we would like
to switch the default to be containerized services.  With this switch
we would also start the deprecation process for deploying services as
bare metal services via puppet.  We still execute the puppet
configuration as part of the container configuration process so the
code will continue to be leveraged but we would be investing more in
the continual CI of the containerized deployments and reducing the
traditional scenario coverage.

As we switch over to containerized services by default, we would also
begin to reduce installed software on the overcloud images that we
currently use.  We have an open item to better understand how we can
switch away from the golden images to a traditional software install
process during the deployment and make sure this is properly tested.
In theory it should work today by switching the default for
EnablePackageInstall[0] to true and configuring repositories, but this
is something we need to verify.

If anyone has any objections to this default switch, please let us know.

Thanks,
-Alex

I think we'd investigate ARA for ansible log and results storage,
since we'd want to save the output.

As for AWX, there wasn't any significant discussion of which I'm
aware. We already have an API (Mistral).

However, the outputs we will get from Heat with "config download" will
be ansible playbooks. So, I think that leaves the door open for a
variety of eventual solutions that can interface with playbooks
(Mistral, AWX, cli, etc).

I don't imagine we'd do anything prohibitive that would prevent
someone from loading those playbooks into AWX if desired, or using
them directly from the cli. You just wouldn't be going through the
official API.

[openstack-dev] [tripleo] Pike Retrospective & Status reporting

[Alex Schultz]

Hey folks,

We started off our PTG with a retrospective for Pike. The output of
which can be viewed here[0][1].

One of the recurring themes from the retrospective and the PTG was the
need for better communication during the cycle.  One of the ideas that
was mentioned was adding a section to the weekly meeting calling for
current status from the various tripleo squads[2].  Starting next week
(Sept 26th), I would like for folks who are members of one of the
squads be able to provide a brief status or a link to the current
status during the weekly meeting.  There will be a spot added to the
agenda to do a status roll call.  It was mentioned that folks may
prefer to send a message to the ML and just be able to link to it
similar to what the CI squad currently does[3].  We'll give this a few
weeks and review how it works.

Additionally it might be a good time to re-evaluate the squad
breakdown as currently defined. I'm not sure we have anyone working on
python3 items.

Thanks,
-Alex

[openstack-dev] [nova][neutron] Queens PTG recap - nova/neutron

[Matt Riedemann]

There were a few nova/neutron interactions at the PTG, one on Tuesday 
[1] and one on Thursday [2].


Priorities
--

1. Neutron port binding extension for live migration: This was discussed 
at the Ocata summit in Barcelona [3] and resulted in a Neutron spec [4] 
and API definition in Pike. The point of this is to shorten the amount 
of network downtime when switching ports between the source and 
destination hosts during a live migration. Neutron would provide a new 
port binding API extension and if available, Nova would use that to bind 
ports on both the source and destination hosts during live migration and 
switch which one is active during post-migration. We discussed if this 
should be dependent on os-vif object negotiation and agreed both efforts 
could be worked concurrently and then we'll see if we should merge them 
at the end, mostly to avoid having to redo a bunch of work if vif 
negotiation comes later. We also discussed if we should make the port 
binding changes on the Nova side depend on moving port orchestration to 
conductor [5] and again agreed to work those separately and see how the 
port binding code looks if it's just started in the nova-compute 
service, mainly since we don't have an owner for [5]. Sean Mooney said 
he could work on the Nova changes for this. The nova spec [6], started 
by John Garbutt in Ocata, would need to get updated for Queens. Miguel 
Lavalle will drive the changes in Neutron.


2. Using os-vif for port binding negotiation: Sean Mooney and Rodolfo 
Alonso already have some proof of concept code for this. We will want to 
get the gate-tempest-dsvm-nova-os-vif-ubuntu-xenial-nv job to be voting 
with any of this code. We also said we could work this concurrently with 
the port binding for live migration work above.


3. Bandwidth-based scheduling: this has a spec already and some work was 
done in Neutron in Pike. There are multiple interested parties in this 
feature. This will depend on getting nested resource providers done in 
Nova, really within the first milestone. Rodolfo owns this as well.


Other discussion


There were several other use cases discussed in both [1] and [2] but for 
the most part they have dependencies on other work, or they don't have 
specs/designs/PoC code, or they don't have owners. So we on the Nova 
side aren't going to be focusing on those other items.

Well, I don't think the explicit call to start() is going to help,
esp. if the number of workers is > 1 since the workers are forked and
need to call start() from their own process space..
In fact, if # of workers > 1 then you not only get an RPC server in
each worker process, you'll end up with an extra RPC
server in the calling thread.

Take a look at a test service I've created for oslo.messaging:

https://pastebin.com/rSA6AD82

If you change the main code to call the new sequence, you'll end up
with 3 rpc servers (2 in the workers, one in the main process).

In that code I've made the wait() call a no op if the server hasn't
been started first.   And the stop method will call stop and wait on
the rpc server, which is the expected sequence as far as
oslo.messaging is concerned.

To me it seems that the bug is in oslo.service - calling wait() before
start() doesn't make sense to me.

I was wrong about this - I failed to notice that each service had

Ugh - didn't keep a copy.  If you pull down that test code you can use
it to generate those traces.

I wasn't at this particular session (wish I could've cloned myself
several times to attend everything) but AWX doesn't change anything as
far as ARA is concerned.
The use cases are different.

One provides things like
ACL/RBAC/authentication/reporting/auditing/running/editing/etc but
also requires memcached, postgres, rabbitmq, a dedicated server and
running your playbooks through it.
The other one provides... reporting and requires 'pip install ara' on
your laptop :)

The folks from Ansible and Tower have reached out to me about
collaborating and talked about integration with AWX/Tower.
I don't know yet what this means and what it will translate to but
I'll have an idea in the next few weeks.

Re: [openstack-dev] Update on Zuul v3 Rollout plans for PTG week

[Monty Taylor]

tl;dr - We didn't roll v3 out at the PTG, current plan is 2017-09-25.

On 09/09/2017 08:55 AM, Monty Taylor wrote:

Heya everybody!

You may or may not be aware that we've been targeting a go-live for Zuul 
v3 for Monday of the PTG. After our status meeting on the topic this 
afternoon we have decided to hold-off and do a bit more work on the 
migration itself while we're in Denver together.


Zuul v3 itself is in great shape, but it turns out a community of 
thousands of developers has produced a LOT of job content over the last 
7 years, and we want to hammer on the translation and migration plans a 
bit more before we unleash it on everyone. If all goes well we're still 
hoping to leave Denver having migrated all the things.


In case you didn't notice, we're still running v2.5. While Zuul v3 
itself is in great shape, we're still getting the job migration script 
solid to the point where we're comfortable the impact will be mimimal 
for most folks.


Since we're doing the Gerrit upgrade today, the new plan is to do the v3 
cutover next Monday, 2017-09-25.


We do not expect the cutover to take a long time - certainly not as long 
as the Gerrit upgrade.


We also had some really good interactions with folks about new job 
content at the PTG, so while we're not rolled out, the time was actually 
very productive.


We have a session planned Monday afternoon to go over v3 and what it 
means at 2:00PM in Vail. That session is still on, however, for those of 
you who either can't be there or prefer reading, we've also put a bunch 
of migration information into the Infra Manual:


   https://docs.openstack.org/infra/manual/zuulv3.html


Quick shout-out to everyone who came to the session. It was scheduled as 
a 30 minute session and wound up lasting 2.5 hours because of all of the 
EXCELLENT questions.


One that came up a few times that's worth bringing up here is:

"What about Third Party CI operators?"

Our STRONG recommendation is for the Third Party folks to hold off and 
not attempt to upgrade immediately. As soon as we're done migrating 
OpenStack we'll be focusing on fleshing out the documentation, and I'm 
sure we'll find some new bugs we need to squash. We'd like to ensure 
bugs have settled down, that there are good operational docs and at 
least a solid Third Party Migration FAQ before Third Party folks upgrade.


We also want to have puppet-openstackci updated properly for people who 
are using that.


Finally, we have written a migration script for OpenStack. It's MOSTLY 
configurable and should be usable by Third Party folks - but as the 
primary focus has been on OpenStack's transition, there are a few 
hard-coded things and a few places where assumptions were likely made. 
We'll want to work with our Third Party community on fixing any 
Infra-specific issues in that script before we recommend a wide rollout.


(PS. Please do not look at the code in the migration script. It is some 
of the ugliest and wonkiest code I've ever written and I wouldn't want 
you all to think less of me)


As we work over the first part of the week you may see Zuul running some 
jobs on your patches and leaving results. If you do - don't freak out, 
it's just us making sure things are working. We also may grab a few of 
you to verify that migrated versions of your jobs are working properly. 
Or you may not notice anything at all until the go-live happens.


We may still do that this week, so the advice holds true. If you see 
Zuul start to comment on patches in your project, don't freak out. 
HOWEVER - if Zuul does leave a comment this week and the results are 
different from what Jenkins leaves, it would be helpful to compare the 
output and let us know if the new Zuul jobs are doing the wrong things.


The content will not be identical, as v3 handles several things 
fundamentally differently. But if you have a job that thinks it's 
testing devstack with magnum enabled and that is not happening, then 
that's very important for us to figure out.


Thanks for your patience! It was great to talk to everyone we were able 
to connect with at the PTG. We're looking forward to rolling this out 
and getting a bunch of new tools in everyone's hands next week.


Thanks!
Monty

Re: [openstack-dev] [TripleO] TripleO/Ansible PTG session

[Joshua Harlow]

Was there any discussion at the PTG on how the newly released AWX[1] 
will affect tripleo/ansible (will it?) or ara or such? Thoughts there?


[1] https://github.com/ansible/awx

James Slagle wrote:

On Wednesday at the PTG, TripleO held a session around our current use
of Ansible and how to move forward. I'll summarize the results of the
session. Feel free to add anything I forgot and provide any feedback
or questions.

We discussed the existing uses of Ansible in TripleO and how they
differ in terms of what they do and how they interact with Ansible. I
covered this in a previous email[1], so I'll skip over summarizing
those points again.

I explained a bit about the  "openstack overcloud config download"
approach implemented in Pike by the upgrades squad. This method
no-op's out the deployment steps during the actual Heat stack-update,
then uses the cli to query stack outputs to create actual Ansible
playbooks from those output values. The Undercloud is then used as the
Ansible runner to apply the playbooks to each Overcloud node.

I created a sequence diagram for this method and explained how it
would also work for initial stack deployment[2]:

https://slagle.fedorapeople.org/tripleo-ansible-arch.png

The high level proposal was to move in a direction where we'd use the
config download method for all Heat driven stack operations
(stack-create and stack-update).

We highlighted and discussed several key points about the method shown
in the diagram:

- The entire sequence and flow is driven via Mistral on the Undercloud
by default. This preserves the API layer and provides a clean reusable
interface for the CLI and GUI.

- It would still be possible to run ansible-playbook directly for
various use cases (dev/test/POC/demos). This preserves the quick
iteration via Ansible that is often desired.

- The remaining SoftwareDeployment resources in tripleo-heat-templates
need to be supported by config download so that the entire
configuration can be driven with Ansible, not just the deployment
steps. The success criteria for this point would be to illustrate
using an image that does not contain a running os-collect-config.

- The ceph-ansible implementation done in Pike could be reworked to
use this model. "config download" could generate playbooks that have
hooks for calling external playbooks, or those hooks could be
represented in the templates directly. The result would be the same
either way though in that Heat would no longer be triggering a
separate Mistral workflow just for ceph-ansible.

- We will need some centralized log storage for the ansible-playbook
results and should consider using ARA.

As it would be a lot of work to eventually make this method the
default, I don't expect or plan that we will complete all this work in
Queens. We can however start moving in this direction.

Specifically, I hope to soon add support to config download for the
rest of the SoftwareDeployment resources in tripleo-heat-templates as
that will greatly simplify the undercloud container installer. Doing
so will illustrate using the ephemeral heat-all process as simply a
means for generating ansible playbooks.

I plan to create blueprints this week for Queens and beyond. If you're
interested in this work, please let me know. I'm open to the idea of
creating an official squad for this work, but I'm not sure if it's
needed or not.

As not everyone was able to attend the PTG, please do provide feedback
about this plan as it should still be considered open for discussion.

[openstack-dev] [nova][cinder] Queens PTG recap - nova/cinder

[Matt Riedemann]

On Thursday morning at the PTG the Nova and Cinder teams got together to 
talk through some items. Details are in the etherpad [1].


Bug 1547142 [2]
---

This is a long-standing bug where Nova does not terminate connections 
when shelve offloading an instance. There was some confusion when this 
was originally reported about whether or not calling 
os-terminate_connection would fix the issue for all backends. The Cinder 
team said it should, and if not it's a bug in the volume drivers in 
Cinder. So we went ahead and rebased the fix [3] which is merged and 
making its way through the stable backports now. This fixes old-style 
attachments. For the new style attachments which get enabled in [4] 
we'll also have to make sure that we create a new volume attachment to 
keep the volume reserved but delete the old attachments for the old host 
connector.


New style volume attach dev update
--

The Cinder team gave an overview of the work completed in Pike and what 
is on-going in Queens for enabling Nova to use new-style volume 
attachments in Cinder, which are based on the 3.27 and 3.44 Cinder API 
microversions. This was also a chance to merge some patches in the 
Queens series and give background to the review teams, mostly on the 
Nova side.


There was general agreement to get the new-style attachment flows merged 
early in Queens so we can flush out bugs and start working on 
multi-attach support.


We also said that we would not work on migrating old style attachments 
to new style in Queens. We don't plan on removing the old flows in Nova 
anytime soon, and once we do we can start talking about migrating data then.


Volume multi-attach
---

Most of the discussion here was around shared volume connections and how 
to model those out of the Cinder API so that Nova can know when it 
should perform a final disconnect_volume call on the host when detaching 
a volume. We agreed that Cinder needs a new API microversion to model 
this which we will then update [4] to rely on that new microversion 
before enabling new style attachments.


We also talked about whether or not we should allow boot from volume 
with an existing multi-attach volume. We decided to allow this but 
disable it via default policy. So there will be a new policy rule in 
both Nova and Cinder:


1. Nova: add a policy rule, disabled by default, to allow boot from 
volume with a multi-attach volume.


2. Cinder: allow multi-attach volumes based on the storage backend 
support, allow multi-attach but only for read-only volumes, or disable 
creating multi-attach volumes altogether. I'm a bit fuzzy on the details 
here, but looking at the existing Cinder API code I don't see any policy 
checks for creating a multiattach volume at all, so this is probably 
something good to add anyway since not all Nova compute drivers are 
going to support multiattach volumes right away.


Ildiko Vancsa is updating the nova spec for multi-attach support for 
Queens with the new details.


Refreshing volume connection_info
-

This was based on a mailing list discussion [5] and the PTG discussion 
was already summarized in that thread [6].


Cinder ephemeral storage


This was a rehash of the Boston forum discussion [7]. We agreed to work 
on both the short term and long term options here.


The short-term option is adding an "is_bfv" attribute on flavors in 
Nova, which defaults to False, but if True would perform a simple boot 
from volume using the specified image and flavor disk details. Think of 
this like get-me-a-network but for boot from volume. Anything more 
detailed, like volume type, guest_format, disk_bus, ephemeral or swap 
disks, would have to be handled through the normal API usage we have 
today. Also, user-defined or image-defined block device mapping 
attributes in the request would supersede the flavor.


The long-term option option is Nova having a Cinder imagebackend driver 
for ephemeral storage. Chet Burgess has started looking at this, and it 
was recommended to look at the ScaleIO imagebackend as a template since 
they both have to solve problems with non-local storage. The good news 
is a Cinder ephemeral imagebackend driver in Nova would not need to deal 
with image caching, since Cinder can do that for us.


--

All in all I felt we had a really productive set of topics and 
discussions between the teams with everyone being on the same page and 
going the same direction, which is nice to see. Boring is good.

[openstack-dev] [TripleO] TripleO/Ansible PTG session

[James Slagle]

On Wednesday at the PTG, TripleO held a session around our current use
of Ansible and how to move forward. I'll summarize the results of the
session. Feel free to add anything I forgot and provide any feedback
or questions.

We discussed the existing uses of Ansible in TripleO and how they
differ in terms of what they do and how they interact with Ansible. I
covered this in a previous email[1], so I'll skip over summarizing
those points again.

I explained a bit about the  "openstack overcloud config download"
approach implemented in Pike by the upgrades squad. This method
no-op's out the deployment steps during the actual Heat stack-update,
then uses the cli to query stack outputs to create actual Ansible
playbooks from those output values. The Undercloud is then used as the
Ansible runner to apply the playbooks to each Overcloud node.

I created a sequence diagram for this method and explained how it
would also work for initial stack deployment[2]:

https://slagle.fedorapeople.org/tripleo-ansible-arch.png

The high level proposal was to move in a direction where we'd use the
config download method for all Heat driven stack operations
(stack-create and stack-update).

We highlighted and discussed several key points about the method shown
in the diagram:

- The entire sequence and flow is driven via Mistral on the Undercloud
by default. This preserves the API layer and provides a clean reusable
interface for the CLI and GUI.

- It would still be possible to run ansible-playbook directly for
various use cases (dev/test/POC/demos). This preserves the quick
iteration via Ansible that is often desired.

- The remaining SoftwareDeployment resources in tripleo-heat-templates
need to be supported by config download so that the entire
configuration can be driven with Ansible, not just the deployment
steps. The success criteria for this point would be to illustrate
using an image that does not contain a running os-collect-config.

- The ceph-ansible implementation done in Pike could be reworked to
use this model. "config download" could generate playbooks that have
hooks for calling external playbooks, or those hooks could be
represented in the templates directly. The result would be the same
either way though in that Heat would no longer be triggering a
separate Mistral workflow just for ceph-ansible.

- We will need some centralized log storage for the ansible-playbook
results and should consider using ARA.

As it would be a lot of work to eventually make this method the
default, I don't expect or plan that we will complete all this work in
Queens. We can however start moving in this direction.

Specifically, I hope to soon add support to config download for the
rest of the SoftwareDeployment resources in tripleo-heat-templates as
that will greatly simplify the undercloud container installer. Doing
so will illustrate using the ephemeral heat-all process as simply a
means for generating ansible playbooks.

I plan to create blueprints this week for Queens and beyond. If you're
interested in this work, please let me know. I'm open to the idea of
creating an official squad for this work, but I'm not sure if it's
needed or not.

As not everyone was able to attend the PTG, please do provide feedback
about this plan as it should still be considered open for discussion.

[openstack-dev] [nova] Queens PTG recap - placement

[Matt Riedemann]

Placement related items came up a lot at the Queens PTG. Some on Tuesday 
[1], some on Wednesday [2], some on Thursday [3] and some on Friday [4].


Priorities for Queens
-

The priorities for placement/scheduler related items in Queens are:

1. Migration allocations [5] - we realized late in Pike that the way we 
were tracking allocations across source and dest nodes during a move 
operation (cold migrate, live migrate, resize, evacuate) was confusing 
and error prone, and we had to "double up" allocations for the instance 
during the move. The idea here is to simplify the resource allocation 
modeling during a move operation by having the migration record be a 
consumer of resource allocations during the move, so we can keep the 
source/dest node allocations separate using the instance/migration 
records. This is mostly internal technical debt reduction and to 
simplify our accounting which should mean fewer bugs.


2. Alternate hosts - this is the work to have the scheduler determine a 
set of alternative hosts for reschedules. This is important for cells v2 
where the cell conductor and nova-compute services can't reach the API 
database or scheduler, so reschedules need to happen within the cell 
given a list of pre-determined hosts chosen by the scheduler at the top. 
Ed Leafe has already started on some of this [6].


3. Nested resource providers [7] - this has been around for awhile now 
but hasn't had the proper reviewer focus due to other priorities. We are 
making this a priority in Queens as it enables a lot of other use cases 
like bandwidth-aware scheduling and being able to eventually remove 
major chunks of the claims code in the ResourceTracker in the compute 
service. We agreed that in Queens we want to try and keep the scope of 
this small and focus on being able to model a simple SR-IOV PF/VF 
relationship. Modeling NUMA use cases will be post-Queens. We will need 
quite a bit of work on functional testing done along with this so that 
we have some fixtures and/or fake virt drivers in place to model things 
like CPU pinning, huge pages, NUMA, SR-IOV, etc which also verify 
allocations in Placement to know we are doing things correctly from the 
client perspective, similar to the functional tests added for verifying 
allocations during move operations in Pike.


General device management
-

This was a more forward looking discussion and the notes are in the 
etherpad [3]. This is not really slated for Queens work except to make 
sure that things we do in Queens don't limit what we can do for 
generically managing devices later, and is tied heavily to the nested 
resource providers work.


Other discussion


Traits - supporting required traits in a flavor is on-going and the spec 
is here [8].


Shared storage providers [9] - we have decided to defer working on this 
from Queens given other priorities. Modeling move allocations with 
migration records should help here though.


Modeling distance for (anti-)affinity use cases - this is being deferred 
from Queens. There are workarounds when running with multiple cells.


Limits and ordering in Placement - Chris Dent has proposed a spec [10] 
so that we can limit the size of a response when getting resource 
providers from Placement during scheduling and also optionally configure 
the behavior of how Placement orders the returned set, so you can pack 
or spread possible build candidates.


OSC plugin - I'm trying to push this work forward. We have the plugin 
installed with devstack now and a functional CI job for the repo but 
need to move some of the patches forward that add the CLI functionality.


There was lots of other random stuff in [2] and [4] but for the most 
part are not prioritized, spec'ed out or have a clear owner, so those 
are not really getting attention for Queens.

You may get a little help from the methods in nova.pci.utils.

If you're calling out to lspci or accessing sysfs, be aware of this

Hi everyone,

Just a quick heads up that at the moment, there is an issue in the
TripleO CI which is in the process of being fixed at the moment:

https://bugs.launchpad.net/tripleo/+bug/1717545

As certain Puppet modules gate for TripleO, please don't recheck
changes that have failing jobs which start with `gate-tripleo-ci-` as
they will fail anyways.

I'll send an update email when things are fixed (or when you see that
bug resolved).

Thank you,
Mohammed

[openstack-dev] [TC][Cyborg] Application For OpenStack Official Project

[Zhipeng Huang]

Hi everyone,

The Cyborg team would like to submit its application for official OpenStack
project under governance[1].

We would like to thank all the TC audience when we did the new project
update session in Denver for the courage and kind words you have provided.
Our overview slide used at that meeting could be found [2].

Look forward to your questions and I (as well as other team members) will
try the very best to answer them. Also look forward to a more exciting
future within the OpenStack community :)

[openstack-dev] [nova]notification update week 38

[Balazs Gibizer]

Hi,

Here is the status update / focus settings mail for w38.

Bugs

[Medium] https://bugs.launchpad.net/nova/+bug/1699115 api.fault
notification is never emitted
We still have to figure out what is the expected behavior here based on:
http://lists.openstack.org/pipermail/openstack-dev/2017-June/118639.html
I think I will propose a patch to remove the api.fault notification to
help start the discussion.

[High] https://bugs.launchpad.net/nova/+bug/1706563
TestRPC.test_cleanup_notifier_null fails with timeout
[High] https://bugs.launchpad.net/nova/+bug/1685333 Fatal Python error:
Cannot recover from stack overflow. - in py35 unit test job
The first bug is just a duplicate of the second. It seems the TetRPC
test suite has a way to end up in an infinite recusion.
I don't know about a way to reproduce it localy or to change the gate
env so that python prints out the full stack trace to see where the
problematic call is. Also adding extra log messages won't help as a
timed out test doesn't have the log messages printed to the logs. So
this bug is pretty stuck.

Versioned notification transformation
-
There are 3 transformation patches that only need a second +2:
* https://review.openstack.org/#/c/454023/ Transform servergroup.create 
notification
* https://review.openstack.org/#/c/483902/ Transform servergroup.delete 
notification
* https://review.openstack.org/#/c/396210/ Transform aggregate.add_host 
notification



Searchlight integration
---
As we discussed on the PTG the Searchlight integration is not likely to 
happen
in the near future so extending the nova notifications is not a 
priority. This

means that we are not planning to add the 'status' field to the instance
notifications. The other task in the current bp
https://blueprints.launchpad.net/nova/+spec/additional-notification-fields-for-searchlight-queens
is to avoid unnecessary BDM DB query when we emit instance 
notifications.
We agreed that we want to do this as it is a meningful optimization of 
the

current code. Patches already proposed and waiting for review:
https://review.openstack.org/#/q/topic:bp/additional-notification-fields-for-searchlight-queens

Small improvements
--

* https://review.openstack.org/#/q/topic:refactor-notification-samples
Factor out duplicated notification sample data
This is a start of a longer patch series to deduplicate notification
sample data. The third patch already shows how much sample data can be
deleted from nova tree. We added a minimal hand rolled json ref
implementation to notification sample test as the existing python json
ref implementations are not well maintained.


Weekly meeting
--
Next subteam meeting will be held on 19th of September, Tuesday 17:00 
UTC on openstack-meeting-4.

Re: [openstack-dev] [glance] Queens PTG: Thursday summary

[Belmiro Moreira]

Hi Brian,
Thanks for the sessions summaries.

We are really interested in the image lifecycle support.
Can you elaborate how searchlight would help solving this problem?

thanks,

Hi Team,

Looks like we incidentally made INSPUR-CI voting for Cinder. For now, it puts 
-1 for all patches. According to [1] please make it non-voting.
