[openstack-dev] Hello everyone, ask a few vm hot plug cpu and ram problem [nova]

[Paul Schlacter]

Like CPU and ram have a maximum value. If I want to produce this product,
provided to the cloud host users.  The maximum value is set to how much
more appropriate.


If the settings are too small, users want to dynamically add CPU or memory,
and can't meet the needs of users.


If the setting is too large, such as max memory set to 40G, current memory
is set to 2G, the virtual machine memory only 1G more, much less than 2G.
If this value is set too large,  Are there any other effects?


Ask your advice.

can you at least provide your requirements?

networking-midonet needs to send the following info to its backend on
AFTER_CREATE/AFTER_UPDATE for router, router_interface, and
floating_ip.
https://github.com/midonet/midonet/blob/fcc127f5c9216b7a563c89d2684461428feb9a67/nsdb/src/main/proto/neutron.proto#L129-L161
(some of fields are actually unused right now. eg. tenant_id)
on AFTER_DELETE, we only need "id" field of the resource.
in feature we want to use PRECOMMIT_xxx events as well. necessary
fields are same as AFTER_xxx.

[openstack-dev] [all] Cinder V1 API Removal

[Sean McGinnis]

Just a heads up for anyone consuming Cinder APIs. The v1 API was 
deprecated in the Juno release, but
we've kept it around for quite awhile because we knew there were client 
implementations out there that

were lagging in getting up to date.

Well, it's now been many releases, and we've had the v1 API disabled by 
default for awhile now. Patch
https://review.openstack.org/#/c/499342/ now removes that API. Queens 
onward, it will not be possible

to run with V1 anymore.

The v3 API is the currently supported version. All tools and 
integrations should now be targeting that API.
This will hopefully be the final API version going forward, with all 
updates and changes being implemented

as microversions under the v3.0 version.

Thanks,

Sean

Re: [openstack-dev] [neutron] out-of-tree l3 service providers

[Isaku Yamahata]

Hi.

Any update on this? Now L3 service provider got the time slot at the PTG.

Yamamoto, do you have any proposal for the interface?
Although ODL surely is interested in L3 flavor, the networking-odl team hasn't
spec or experimental patch yet unfortunately.
Dragon flow folks seems to have their own spec.

apologies, do you have more details on what 'X-Is-Admin-Project' is? i'm 
not familiar with this header.

currently, the behaviour is that:
- a member of a project can only see its own events
- an admin of a project can see all the events of a project (and any 
events without any project associated with it)

if this is the way of denoting a user is a 'super-admin' that has access 
to all events, i'm ok with it.

Some more background information is in the ironic spec here:

https://review.openstack.org/#/c/500429/

Also, be aware of these release notes for Pike related to baremetal 
scheduling:


http://docs-draft.openstack.org/77/501477/1/check/gate-nova-releasenotes/1dc7513//releasenotes/build/html/unreleased.html#id2

In Pike, nova is using a combination of VCPU/MEMORY_MB/DISK_GB resource 
class amounts from the flavor during scheduling as it always has, but it 
will also check for the custom resource_class which comes from the 
ironic node. The custom resource class is optional in Pike but will be a 
hard requirement in Queens, or at least that was the plan. The idea 
being that long-term we'd stop consulting VCPU/MEMORY_MB/DISK_GB from 
the flavor during scheduling and just use the atomic node.resource_class 
since we want to allocate a nova instance to an entire ironic node, and 
this is also why the Exact* filters were used too.


There are more details on using custom resource classes for scheduling here:

https://specs.openstack.org/openstack/nova-specs/specs/pike/approved/custom-resource-classes-in-flavors.html

Nisha is raising the question about whether or not we're making 
incorrect assumptions about how people are using nova/ironic and they 
want to use the non-Exact filters for VCPU/MEMORY_MB/DISK_GB, which as 
far as I have ever heard is not recommended/supported upstream as it can 
lead to resource tracking issues in Nova that eventually lead to 
scheduling failures later because of the scheduler thinking a node is 
available for more than one instance when it's really not.

Hi Ironic Operators,

To be more specific, at your datacentre/production environment what all

scheduling an ironic node? Do you use RamFilter/DiskFilter/CoreFilter in
the "use_baremetal_filters" for ironic nodes scheduling from nova?

noted in bug #1698010 [1], the domain name part of this is based up
nova's 'dhcp_domain' option, which is a nova-network option that has
been deprecated [2].
  
I've started work on a fix [3] that will allow us to retrieve this

information from neutron instead, uncoupling us from this legacy
option. However, some commentators have pointed out that this may not
necessarily be what we want to do: a FQDN is a hostname and domain
name, and using one as a hostname may not be that clever nor correct.

My networking fu isn't strong enough to deliver a verdict so I'm hoping
someone else can make my mind up for me: do we want to migrate this
feature to neutron, or do we want to stop using FQDN and just use
instance names?


Hi,

Your patch https://review.openstack.org/#/c/480616/ requires that neutron
expose the ‘DNS Integration’ extension be support by neutron and the
relevant networking plugin. If it does not then will be a regression and
things will not work.

In addition to this that is per network and not global so there will also
be a regression for running instances if nova is updated.


OK, so ultimately this isn't something we can rely on from neutron? Does
that mean we should abandon the idea of providing FQDN when using neutron?
Mores to the original point, is there any reason we would want to/should
use FQDN?


TripleO gets its FQDNs from this feature, which is how I noticed it was
still using the deprecated nova.conf value.  So we need some way to
maintain that functionality.  I'm not sure what would happen if
cloud-init stopped getting an FQDN - would it just set the hostname but
leave the domain as whatever was provided via DHCP?  If so I think that
would be acceptable for us.


OK, and we do want to use a FQDN as the hostnames inside the guest? That's my
key question. Random ServerFault questions seems to suggest no clear answer to
this [1].


It's true that there is no definitive answer there, but I will point out 
this: At least three different answers say something along the lines of 
"I normally use just the shortname, but I discovered that [application] 
requires the hostname to be an FQDN."  The three examples I see are some 
Oracle applications, FreeIPA, and Ganeti.  I know we ran into issues 
with non-FQDN hostnames in TripleO as well, probably for either Puppet 
or RabbitMQ.  I know they're both hostname-sensitive, I just don't 
recall which was FQDN-sensitive too.  That's why one of the first steps 
of the undercloud install says "Ensure that there is a FQDN hostname set 
and that the $HOSTNAME environment variable matches that value."


In that case we even went so far as to codify the hostname configuration 
to make sure everything was FQDN and consistent.  So I guess my vote 
would be in favor of hostname as FQDN, which I realize doesn't simplify 
this discussion at all. :-)





On the other hand, since it turns out this configuration option isn't
only used with nova-network maybe it should just be un-deprecated?
Perhaps with an update so that it is only used when Neutron doesn't
provide an FQDN?


You're correct in pointing out that it's not only used by nova-network, but
this seemed to be a mistake. The main issue I saw was that the nova-network
option is completely divorced from the neutron configuration and is static.
However, if we can't guarantee that this information will be available from
neutron, then perhaps a static configuration option is the only way to go? It's
quite the pickle.

[openstack-dev] Unified Limits work stalled - next steps, need for new leadership

[Sean Dague]

This is an email that's probably overdue, but time gets away from all of 
us. Coming out of Atlanta and even Boston we were pushing pretty hard on 
a new approach to unify limits, as well as building the infrastructure 
to have hierarchical limits possible in OpenStack (keystone merged spec 
- 
https://specs.openstack.org/openstack/keystone-specs/specs/keystone/ongoing/unified-limits.html)


However, this effort pretty much as run out of gas, and really needs a 
new driver (or set of drivers) to make forward progress. My current set 
of responsibilities doesn't really make it possible for me to own 
driving this (though I will be happy to help others). That seems to also 
be true of many of the others that were engaged.


This is going out in advance of the PTG in case any developer(s), or 
organizations feel that hierarchical limits are a priority for them, and 
would be willing to step up there. If so please feel free to reach out, 
and we can carve out some PTG time in helping a new push organize here.


However, without new leadership here, the current plan is to just put 
the effort to rest.

[openstack-dev] [panko][ceilometer][keystone] Support X-Is-Admin-Project

[Innus, Martins]

Hi,
Just getting started with OpenStack and one of the stumbling blocks so 
far is that unless I missed it, there is no way for the main admin user to 
request event data for all projects:

[root@srv-m10-05-02 keystone]# ceilometer event-list -q 
'event_type=compute.instance.create.start'
+++---++
| Message ID | Event Type | Generated | Traits |
+++---++
+++---++



Where there are definitely instances running and the user that created them has 
no issue seeing the events:

[minnus@srv-m10-05-02 ~]$ ceilometer  event-list -q 
'event_type=compute.instance.create.start' --limit 1
+--+---++---+
| Message ID   | Event Type| 
Generated  | Traits 
   |
+--+---++---+
| b7ce7652-9745-487d-9fcc-570c7c972080 | compute.instance.create.start | 
2017-08-29T15:37:39.707727 | 
+--+-+--+ |
|  |   |
| |   name   |   type  |  value

……


The fix seems to be something like the attached patch and setting the 
appropriate configs in keystone.conf.


One curious thing is that with the default keystone config, requests from all 
projects have "X-Is-Admin-Project: True”

If I set admin_project_domain_name and admin_project_name , only then do the 
non admin projects have the header set to False.

This is on:
 - Centos 7.3
 - Ocata
 - Panko backed by MariaDB.

Is this change something that would be accepted?

Thanks!

Martins

[Mooney, Sean K] I like this idea in general, that said in ovs-dpdk we modified
ovs to schedule the vhost-user port to be processed on a pmd that is on the same

[Mooney, Sean K] actually we have so poc code you should proably review

[Mooney, Sean K] in terms of basic numa affinity this is not as important
With ovs-dpdk because we make best effort to fix it in ovs this is less pressing
Then it used to be. It is still important for other backbends but we need
Also have a mechanism to control numa affinity policy like 
 https://review.openstack.org/#/c/361140/ to not break existing deployments.

I have some taught about modeling network backbends
in placement and also passing traits requests for neutron that this would dove
tail with so would love to talk to anyone who is interested in this.
By modeling ovs and other network backend in placement and combining that
With traits and the nova-neutron negotiation protocol we support several
Advance usescase.

By the way  ovs-dpdk allow you to specify vhost-port rx/tx queue mapping 
to pmd which could give a nice performance boost if done correctly. It
might be worth extending os-vif to do that in the future though this could
equally be handeled by the neutron ovs l2 agent.

Re: [openstack-dev] removing screen from devstack - RSN

[Walter Boring]

I completely agree with you here John.   I still prefer to use screen for
my devstack installs, it's just far far easier to use for development.
 systemd is a pain to use in comparison.
This is a major step backwards for developers.

Re: [openstack-dev] removing screen from devstack - RSN

[Eric Fried]

John-

You're not the only one for whom the transition to systemd has been
painful.

However...

It *is* possible (some would argue just as easy) to do all things with
systemd that were done with screen.

For starters, have you seen [1] ?

Though looking at that again, I realize it could use a section on how
to do pdb - I'll propose something for that.  In the meantime, feel free
to find me in #openstack-dev and I can talk you through it.

Re: [openstack-dev] removing screen from devstack - RSN

[Sean McGinnis]

​FWIW I realize my opinion doesn't count here particularly since this 
already merged, BUT I also realize that it didn't count before it 
merged either as the response I was given was "I don't use 
debuggers".  It's unfortunate, perhaps I'm really the only one that 
has counter opinions on things, or maybe nobody else wants to speak 
up, or maybe just nobody cares.  Either way, it's a bit of a bummer 
and just another thing on the list.  ​




You are not alone. At the same time we are discussing ways to simplify 
things to ease the burden on development,

we are also making it more difficult, especially for newcomers.

I would have hoped we had come up with a solution for interactive 
debugging before we pulled the plug too. "Don't"

really doesn't seem like the right answer here.

Where was this plan discussed too? I must have missed the planning for 
this change.

Re: [openstack-dev] removing screen from devstack - RSN

[John Griffith]

Please don't, some of us have no issues with screen and use it extensively
for debugging.  Unless there's a viable option using systemd I fail to
understand why this is such a big deal.  I've been using devstack in screen
for a long time without issue, and I still use rejoin that supposedly
didn't work (without issue).

I completely get the "run like customers" but in theory I'm not sure how
screen makes it much different than what customers do, it's executing the
same binary at the end of the day.  I'd also ask then is devstack no longer
"dev" stack, but now a preferred method of install for running production
clouds?  Anyway, I'd just ask to leave it as an option, unless there's
equivalent options for things like using pdb etc.  It's annoying enough
that we lost that capability for the API services, is there a possibility
we can reconsider not allowing this an option?

Thanks,
John

[openstack-dev] [all][api] POST /api-sig/news

[michael mccune]

Greetings OpenStack community,

This week's meeting was mainly focused on discussion of plans for the 
PTG and about improving the outreach efforts of the SIG.


The API-SIG will have a room on Monday and Tuesday at the PTG. In 
addition to the guided review process [6] we've mentioned before, 
there's an etherpad [5] where an agenda of topics is being planned. We 
will be sharing some of the time with people interested in SDKs and 
other issues related to consuming APIs. If there are gaps we will be 
performing live readings of mordred's version and service discovery epic 
[4].These readings may or may not involve hand puppets.  If you would 
like to propose a topic for the PTG, please add it to the aforementioned 
etherpad.


In addition to our discussion of events for the PTG, we also talked 
about how we can improve our outreach and messaging to the wider 
OpenStack community. This was predicated by a review of our email 
advertising the guided review process. Although we have talked about 
this topic and taken steps to advance the SIG in the past, a fresh take 
on this discussion revolved around the notion of reaching project teams 
earlier in their API design process. Starting after the PTG, the API-SIG 
will investigate reaching out to projects which are still incubating 
with the hope that interacting with these teams early in their lifecycle 
will be of maximum benefit.


# Newly Published Guidelines

None this week.

# API Guidelines Proposed for Freeze

Guidelines that are ready for wider review by the whole community.

* Explain, simply, why extensions are bad
  https://review.openstack.org/#/c/491611/

# Guidelines Currently Under Review [3]

* A (shrinking) suite of several documents about doing version and 
service discovery

  Start at https://review.openstack.org/#/c/459405/

* WIP: microversion architecture archival doc (very early; not yet ready 
for review)

  https://review.openstack.org/444892

# Highlighting your API impacting issues

If you seek further review and insight from the API WG, please address 
your concerns in an email to the OpenStack developer mailing list[1] 
with the tag "[api]" in the subject. In your email, you should include 
any relevant reviews, links, and comments to help guide the discussion 
of the specific challenge you are facing.


To learn more about the API WG mission and the work we do, see OpenStack 
API Working Group [2].


Thanks for reading and see you next week!

[openstack-dev] [nova] [neutron] Adding neutron VIF NUMA locality support

[Stephen Finucane]

Hey,

NUMA locality matters as much for NICs used e.g for Open vSwitch as for SR-IOV
devices. At the moment, nova support NUMA affinity for PCI passthrough devices
and SR-IOV devices, but it makes no attempt to do the same for other NICs. In
the name of NFV enablement, we should probably close this gap.

I have some ideas around how this could work, but they're fuzzy enough and
involve exchanging os-vif objects between nova and neutron. This is probably
the most difficult path as we've been trying to get os-vif objects over the
nova-neutron wire for a while now, to no success.

Anyone else keen on such a feature? Given that there are a significant amount
of people from nova, neutron, and general NFV backgrounds at the PTG next
week, we have a very good opportunity to talk about this (either in the nova-
neutron sync, if that's not already full, or in some hallway somewhere).

At this point in the day, this is probably very much a Rocky feature, but we
could definitely put in whatever groundwork is necessary this cycle to make the
work in Rocky as easy possible.

Cheers,
Stephen

[openstack-dev] [kolla] [neutron] PTG cross-platform meetup possibility

Hi neutron team,

Would there be any interest in meeting with the Kolla team at the PTG to 
discuss neutron’s
integration with containers and Kubernetes especially about the new networking
technologies like VPP, fd.io, OpenDaylight, OVS-DPDK, OVN, service chaining

If yes, would Tuesday 2 pm work?  I’m thinking about an hour or two for the

That's great feedback.

Good call. I'll re-post this to the operators mailing list (with the above

[openstack-dev] [neutron][oslo.db] db retry madness

[Michael Bayer]

I'm trying to get a handle on neutron's retry decorators.I'm
assisting a developer in the networking_odl project who wishes to make
use of neutron's retry_if_session_inactive decorator.

The developer has run into several problems, including that
networking_odl methods here seem to accept a "session" directly,
rather than the "context" as is standard throughout neutron, and
retry_if_session_inactive assumes the context calling pattern.
Additionally, the retry_db_errors() decorator which is also used by
retry_if_session_inactive is doing a deepcopy operation on arguments,
which when applied to ORM-mapped entities, makes a copy of them which
are then detached from the Session and they fail to function beyond
that.

For context, the developer's patch is at:
https://review.openstack.org/#/c/500584/3

and the neutron features I'm looking at can be seen when they were
reviewed at: https://review.openstack.org/#/c/356530/22


So I have a bunch of questions, many are asking the same things: "is
networking_odl's pattern legacy or not?" and "is this retry decorator
buggy?"   There's overlap in these questions.  But "yes" / "no" to
each would still help me figure out that this is a giraffe and not a
duck :) ("does it have a long neck?" "does it quack?" etc)

1. since the retry_if_session_inactive decorator assumes functions
that receive a "context", what does it mean that networking_odl uses
functions that receive a "session" and not a "context" ?   Should
networking_odl be modified such that it accepts the same "context"
that Neutron passes around?

2. Alternatively, should the retry_if_session_inactive decorator be
modified (or a new decorator added) that provides the identical
behavior for functions that receive a "session" argument rather than a
"context" argument ?  (or should this be done anyway even if
networking_odl's pattern is legacy?)

3. I notice that the session.is_active flag is considered to be
meaningful.   Normally, this flag is of no use, as the enginefacade
pattern only provides for a Session that has had the begin() method
called.  However, it looks like in neutron_lib/context.py, the Context
class is providing for a default session
"db_api.get_writer_session()", which I would assume is how we get a
Session with is_active is false:

3a.  Is this a temporary measure to work around legacy patterns?
3b.  If 3a., is the pattern in use by networking_odl, receiving a
"session" and not "context", the specific legacy pattern in question?
3c.  if 3a and 3b, are we expecting all the various plugins to
start using "context" at some point ?  (and when they come to me with
breakage, I can push them in that direction?)

4. What is the bug we are fixing by using deepcopy() with the
arguments passed to the decorated function:

4a.  Is it strictly that simple mutable lists and dicts of simple
types (ints, strings, etc.) are preserved across retries, assuming the
receiving functions might be modifying them?

4b. Does this deepcopy() approach have any support for functions
that are being passed not just simple structures but ORM-mapped
objects?   Was this use case considered?

4c. Does Neutron's model base have any support for deepcopy()?  I
notice that the base classes in model_base do **not** seem to have a
__deepcopy__ present.  This would mean that this deepcopy() will
definitely break any ORM mapped objects because you need to use an
approach like what Nova uses for copy():
https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/models.py#L46
.  This would be why the developer's objects are all getting kicked
out of the session.   (this is the "is this a bug?" part)

4d. How frequent is the problem of mutable lists and dicts, and
should this complex and actually pretty expensive behavior be
optional, only for those functions that are known to receieve mutable
structures and change them in place?

Would there be some interest from Cinder and Ironic (and others of course) team

Also it would give the Kolla team an opportunity to hear about your teams 
interest and experiences in containerization and what you need from Kolla going 
forward.

I'm thinking an hour or two on Monday afternoon, the first day of the PTG?

Re: [openstack-dev] [keystone] [nova] [neutron] [cinder] [ironic] [glance] [swift] Baremetal/VM SIG PTG Schedule/Etherpad

out for the Baremetal/VM SIG. All the sessions/ideas/carry-over topics
from Boston have been filtered into a schedule and is available in the
etherpad [0].

Each entry should have a "lead" to drive the discussion and a "goal" to
work towards. I took a stab at listing leads and goals accordingly, but
if you're more familiar with the topics, please adjust as necessary. If
you noticed a conflict with another session, feel free to respond here,
leave a comment in the etherpad, or ping me on IRC. I know it's a bit
late, but I'd like to have the schedule pretty well set by the weekend.

Thanks!

An easy way to check for broken links:

We moved everything out from docs.openstack.org/developer, any such link
in your code is outdated and needs updating,

We realized recently that we haven't publicized some of the tools
in the releases repository very well. One tool that will be useful
this week as you prepare your release candidates is the 'new-release'
command, which edits a deliverable file to add a new release from
HEAD of the given branch, automatically computing the next verison
number based on the inputs.

Use the ``venv`` tox environment to run the tool, like this:

  $ tox -e venv -- new-release SERIES DELIVERABLE TYPE

The SERIES value should be the release series, such as "pike".

The DELIVERABLE value should be the deliverable name, such as
"oslo.config" or "cinder".

The TYPE value should be one of "bugfix", "feature", "major",
"milestone", or "rc".

If the most recent release of cinder during the pike series is
11.0.0.0b3 then running:

  $ tox -e venv -- new-release pike cinder rc


On systems with Python 3 by default this fails on installing
lazr.restfulclient.
I think we should add

basepython = python2

for now.


I wonder if you have an old copy of the releases repo. In master we
explicitly set basepython to python3 and lazr.restfulclient is no longer
a dependency.


Updated to latest HEAD, removed *.pyc files and .tox. Still getting:

I cannot find where this dependency comes from, still investigating.


And here is what helped: rm -rf *.egg-info/

I suspect it was coming from stale directory releases.egg-info (currently we
have openstack_releases.egg-info instead). I'm not sure why it was picked..


Yes, that's odd, but I'm glad you found the problem.

I see you're running with python 3.6. I've only tested with 3.5 so far,
so I would appreciate bug reports or patches if you find issues.


So far so good. I haven't had any problems with doing Pike releases on it.

This patch is in the gate and now merging, and with it devstack now has
a single run mode, using systemd units, which is the same between test
and development.

Thanks to everyone helping with the transition!

That's still going to be backwards-incompatible with the way it's been
shipped for quite a while now. Passing ENV vars or something to point to
specific config files is going to need to be explored.

[openstack-dev] [ptg][heat] Heat PTG + Virtual meetup Agenda

[Rico Lin]

Hi heat members

As we're going to have PTG in Denver(and online)
Here are schedules and Etherpads for it [1].

Encourage all to join us remotely if you can't make it to Denver!, we
welcome anyone shares their ideas, experiences, efforts, and stories to us
to help us make our design/implement better.

Attached an ics file, feel free to add it to your calendar

As we discussed in heat meeting, this Heat PTG will be a mixed format,
Physical PTG room + Virtual Online channel together.
The virtual link will share in [1], and if anything went wrong(like we have
to change room URL), we will update to etherpad as well. So keep update to
date with the etherpad.

Also please notice that we won't host team meeting next week.

Re: [openstack-dev] [nova] [placement] Modeling SR-IOV with nested resource providers

[Andrey Volkov]

Ed,

Thanks for the response.

I'm also interested how those models can be used from two points of view.

First, how I can request the desired configuration. I thought about
some anti-affinity logic based on traits in Placement, but probably
that's not a task for Placement. Solution Jay Pipes proposed [1] is to
make several requests to /allocation_candidates and then combine a new
request from responses.

Second, how complicated it would be to update resource provider structure
if some conditions are changed (port was connected to a different switch).
I agree that simple structure is preferable here, for me having PFs as
resource providers
and VFs as inventories with tags (third option in the previos post) is
closer
to reality than hierarchical resource providers. What do you think?

FYI Eric Fried started an etherpad about generic device management [2].

[openstack-dev] [opensatck] [freezer] Looking for a worked intallation guide for freezer

[hanc...@iscas.ac.cn]

Hello,

Among the projects in OpenStack, freezer is the rare one who does the data 
backups and disaster recovery. This really attracts me on working on it.

However, I sufferred several pitfalls during the installation. The 
"installation guide" in the project wiki page shows the installation for the 
mitaka release? However, it did not help much even on a mitaka based openstack. 
I have spent a few days already, but the freezer-api even could not be 
installed and configured correctly. I also followed the guide from the official 
github. The similar result (failure) returns to me... It all happens on the 
"db-sync" or "db-init" steps... 

I wonder is there an up-to-date guide for the service installation anywhere? Or 
specifically for a release, like mitaka, but worked tutorial that can lead me 
to a successful installation?
Rare detailed information of this project can be found over the Internet. Hope 
anyone who can leave me a hint. I would be very appreciated. :)

PS: By the way, is the Swift a necessary service to guaranteeing freezer 
working properly?

Thanks,
Chao
