[ops][glance][nova] scheduling problem because of ImagePropertiesFilter
by Massimo Sgaravatto 29 Jul '19

29 Jul '19

We have just finished the update of our cloud to Rocky but we are seeing a strange issue with images with property: hypervisor_type='QEMU' The scheduling of instances created with such images fails because of the ImagePropertiesFilter [*] Removing that property from the image, the scheduling works. We also tried changing hypervisor_type='QEMU' --> hypervisor_type='qemu', but this didn't help. Any suggestions? Thanks, Massimo [*] 2019-07-17 13:52:58.148 13312 INFO nova.filters [req-1863bef0-0326-46d1-a836-436227e91eef 6e3b136d578f4292a5c03b16f443ab3d d27fe2becea94a3e980fb9f66e2f291a - default default] Filtering removed all hosts f\ or the request with instance ID '63810b60-76e4-4e76-a1c3-e4d3932c002e'.

[tc][all] seeking candidates to run in the next TC election
by Doug Hellmann 29 Jul '19

29 Jul '19

Nominations for the next Technical Committee term open on 27 August, just over 4 weeks from now. In the past, we have had people wait until the last minute to consider running, and then in some cases they had issues getting approval from their managers to serve in the role. This time, since I know there will be at least one open seat when I step down, I thought it would be a good idea to start that recruiting process a little earlier. Our community places a high value on democratically electing representative leadership — selecting members of the community to help steer the project. That system only works if we have people willing and able to serve in the elected roles like the Technical Committee. There is no fall-back option. We need community members to step up and run. So, if you are interested in serving on the TC, now is the time ask the necessary questions within your company. If you need advice about how to approach your manager, any current TC member, including me, would be happy to help you. Doug

[requirements] changes in requests library maintainership
by Doug Hellmann 29 Jul '19

29 Jul '19

It looks like the Kenneth Reitz, the primary maintainer of the requests library, is stepping down [1]. There are several offers to take over right now, so it's not really clear to me what's going to happen. I think we'll want to keep an eye on both requests and requests3 until the new maintainer is designated. And of course if anyone is interested in helping out, I encourage you to get involved in the discussion on github. [1] https://github.com/not-kennethreitz/team/issues/21 -- Doug

[ironic][edge] L3/DHCP-Less deployments
by Julia Kreger 29 Jul '19

29 Jul '19

Greetings everyone! Over the last few weeks, I've had numerous discussions with contributors who have expressed interest in the DHCP-less deployment method specification document[0]. It seems many parties are interested! I think the path forward at this time is to get everyone talking about where and how they can help push this feature forward. If those interested could propose time windows when they are available, I'll try to find a mutual time window where we can try to get everyone on IRC or on a call and try to map out the next steps together. Sound good? -Julia [0]: https://specs.openstack.org/openstack/ironic-specs/specs/not-implemented/L3…

[nova][sfe] Use PCPU and VCPU in One Instance
by David Wang 29 Jul '19

29 Jul '19

Hi, We are proposing a Nova spec for the feature of creating an instance of mixed dedicated CPUs and shared CPUs and experience communities review. The spec link is https://review.opendev.org/#/c/668656/ and spec name is "Use PCPU and VCPU in One Instance". I recognized that Nova Sepc for Train release is frozen, I'd like to request a spec freeze exception process and let the spec to be merged in train release. I may have trouble in attending next week's team meeting, on Aug 1, so, please discuss in the email thread. Thanks Huaqiang

[osc] Very slow openstack commands in Stein Devstack running on VM
by Bernd Bausch 29 Jul '19

29 Jul '19

I run Stein Devstack in a virtual machine. Occasionally, openstack client commands take minutes to complete, which didn't happen at earlier releases, and which is rather annoying. The delay seems to take place at an early stage: Even when I forget to set the OS_* environment, it takes minutes until I am told that the request requires authentication. Interrupting the command, the stack trace confirms this (as a side remark, it also takes a long while until my ^C is processed): Traceback (most recent call last): File "/usr/local/bin/openstack", line 7, in <module> from openstackclient.shell import main File "/usr/local/lib/python2.7/dist-packages/openstackclient/shell.py", line 22, in <module> from osc_lib.api import auth File "/usr/local/lib/python2.7/dist-packages/osc_lib/api/auth.py", line 19, in <module> from keystoneauth1.loading import base File "/usr/local/lib/python2.7/dist-packages/keystoneauth1/loading/__init__.py", line 13, in <module> from keystoneauth1.loading import adapter File "/usr/local/lib/python2.7/dist-packages/keystoneauth1/loading/adapter.py", line 13, in <module> from keystoneauth1 import adapter File "/usr/local/lib/python2.7/dist-packages/keystoneauth1/adapter.py", line 17, in <module> from keystoneauth1 import session File "/usr/local/lib/python2.7/dist-packages/keystoneauth1/session.py", line 25, in <module> import requests File "/usr/local/lib/python2.7/dist-packages/requests/__init__.py", line 95, in <module> from urllib3.contrib import pyopenssl File "/usr/local/lib/python2.7/dist-packages/urllib3/contrib/pyopenssl.py", line 48, in <module> from cryptography.hazmat.backends.openssl import backend as openssl_backend File "/usr/local/lib/python2.7/dist-packages/cryptography/hazmat/backends/openssl/__init__.py", line 7, in <module> from cryptography.hazmat.backends.openssl.backend import backend File "/usr/local/lib/python2.7/dist-packages/cryptography/hazmat/backends/openssl/backend.py", line 2419, in <module> backend = Backend() File "/usr/local/lib/python2.7/dist-packages/cryptography/hazmat/backends/openssl/backend.py", line 119, in __init__ self.activate_osrandom_engine() File "/usr/local/lib/python2.7/dist-packages/cryptography/hazmat/backends/openssl/backend.py", line 163, in activate_osrandom_engine with self._get_osurandom_engine() as e: File "/usr/lib/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/local/lib/python2.7/dist-packages/cryptography/hazmat/backends/openssl/backend.py", line 146, in _get_osurandom_engine res = self._lib.ENGINE_init(e) KeyboardInterrupt My wild speculation is that the delay has something to do with obtaining a random number, which can be a problem on virtual machines due to their lack of entropy. My knowledge in this area is paper-thin, though. And I wonder what happens to all the Devstacks used in CI? Thus my questions: *Is the delay really caused by my running the cloud on a VM? What can I do to improve this?* Thanks, Bernd

[goals][IPv6-Only Deployments and Testing] Week R-12 Update
by Ghanshyam Mann 29 Jul '19

29 Jul '19

Hello Everyone, I am starting this status email for 'IPv6-Only Deployments and Testing ' community goal for Train. Storyboard: ========= - https://storyboard.openstack.org/#!/story/2005477 Current status: ============ 1. Base job 'devstack-tempest-ipv6' has been prepared on Tempest (patch yet to merge)[1] 2. 'tempest-ipv6-only' is defined in Tempest (patch yet to merge)[1] 3. 'tempest-ipv6-only' has been proposed to run on 5 services project date side [2]. 4. I have proposed few more projects jobs like congress etc and will keep doing for other projects also. 5. Neutron stadium projects jobs. I talked to slaweq on IRC [3]on what all neutron stadium falls under the IPv6 address communication criteria so that we can add ipv6-only job for those project only. He is going to prepare the list of those project and accordingly we will add jobs Everything related to this goal can be found under this topic: Topic: https://review.opendev.org/#/q/topic:ipv6-only-deployment-and-testing+(stat… How to define and run new IPv6 Job on project side: ======================================= - I prepared a wiki page to describe this section - https://wiki.openstack.org/wiki/Goal-IPv6-only-deployments-and-testing - I am adding this wiki info in goal doc also[4]. Review suggestion: ============== - Main goal of these jobs will be whether your service is able to listen on IPv6 and can communicate to any other services either OpenStack or DB or rabbitmq etc on IPv6 or not. So check your proposed job with that point of view. If anything missing, comment on patch. - One example was - I missed to configure novnc address to IPv6- https://review.opendev.org/#/c/672493/ - base script as part of 'devstack-tempest-ipv6' will do basic checks for endpoints on IPv6 and some devstack var setting. But if your project needs more specific varification then it can be added in project side job as post-run playbooks as described in wiki page[5].

[tripleo] Roadmap to simplify TripleO
by Emilien Macchi 29 Jul '19

29 Jul '19

Even though TripleO is well known for its maturity, it also has a reputation of being complex when it comes to the number of tools that it uses. Somewhat related to the efforts that James is leading with "Scaling TripleO" [1] [2], I would like to formalize our joint efforts to make TripleO simpler in the future. Some work has been done over the last releases already and yet we have seen net benefits; however we still have challenges ahead of us. - With no UI anymore, do we really need an API? - How can we reduce the number of languages in TripleO? ... and make Python + Ansible the main ones. - How can we reduce our dependencies? I created a document which explains the problems and propose some solutions: https://docs.google.com/document/d/1vY9rsccgp7NHFXpLtCFTHQm14F15Tij7lhn5X_P… For those who can't or don't want Google Doc, I've put together the notes into etherpad [3] and I'll take care of making sure it's updated at last at the beginning until we sort things out. Feel free to be involved: - comment or suggest edits if you have feedback / ideas - sign-up if you're interested to contribute For now I expect this document to be a clear place what our plan is but I wouldn't be surprised if in the future we break it down into specs / blueprints / etc for better tracking.

[requirements] docutils-0.15.1 pypi missing wheel
by Matthew Thode 28 Jul '19

28 Jul '19

Hi, In trying to update openstack past the broken 0.15 release to the 0.15.1 bugfix release I ran into a problem when trying to install it in python3 (we are currently testing on ppython 3.6). It seems like the missing wheel is the issue. When do you plan on publishing it? The following demonstrates the issue. The logs are not kept forever but it's a standard error. ERROR: No matching distribution found for docutils===0.15.1 http://logs.openstack.org/73/672873/3/check/requirements-tox-py36-check-uc/… It seems like other devs/users have reported the problem as well but there hasn't been any activity to address it. See the following messages: https://sourceforge.net/p/docutils/mailman/message/36726543/ https://sourceforge.net/p/docutils/mailman/message/36726888/ Please let me know if you need anything else from me. -- Matthew Thode

[nova] Train Cycle Themes - An Interactive Experience
by Eric Fried 27 Jul '19

27 Jul '19

Hi all. Now that we're past spec freeze, Matt suggested I write a report on how we're doing against our cycle themes. That sounded really tedious and boring and project-managementy, so I thought I would spread the joy. Bear with me, this is going to be a little different. I've created a null review in the nova-specs repository [1]. I'd like us to use this as a mechanism to collaboratively gather thoughts via review comments [2]. I've made a start on some bits. Have fun! efried [1] https://review.opendev.org/#/c/673095/ [2] I could have used an etherpad. But this will be more... permanent.

Forcing restart of a worker node with running guest
by Mauricio Tavares 27 Jul '19

27 Jul '19

So one of my worker nodes is, to put it mildly, rather unhappy: Message from syslogd@openstack-w1 at Jul 25 15:57:49 ... kernel:NMI watchdog: BUG: soft lockup - CPU#3 stuck for 22s! [vnc_worker:9141] Message from syslogd@openstack-w1 at Jul 25 15:57:57 ... kernel:NMI watchdog: BUG: soft lockup - CPU#10 stuck for 22s!

[migration/8:49] I found out when it was taking 30 min to delete a guest. So, what I can do in a forceful way? 1. How to kill the guest? Can I kill it through virsh or openstack compute service will get sad? 2. What would happen if I stop the compute service? 3. What would happen if I get really annoyed and tell worker node to reboot?

[nova][sfe] Train Spec Freeze Exception Process
by Eric Fried 26 Jul '19

26 Jul '19

Hello Nova. Spec freeze happened, which means we won't be approving any more specs for Train. Unless we do. >From this point on, you will be required to run the following gauntlet if you want your spec to land in Train. - Put your name and a link to your spec on the agenda for the next Nova meeting [1][2]. - Send a note to openstack-discuss tagged with [nova][sfe] (like this one is) including the spec for which you are requesting an exception, and noting the date of the meeting. - Attend that meeting and state your case. Assuming a quorum of cores is present, we will attempt to render a decision, or at least indicate what further actions are necessary. Thanks, efried [1] https://wiki.openstack.org/wiki/Meetings/Nova#Agenda_for_next_meeting [2] If you can't attend a meeting, or "next Thursday" is just too long to wait, say so in your email and we'll endeavor to discuss it entirely on the mailing list.

[nova][oslo.log] global_request_id help
by Eric Fried 26 Jul '19

26 Jul '19

While doing something unrelated, I noticed this code [0] that shouldn't need to exist if global_request_id is working. I threw out some debug patches [1] to dump headers. Results: [2] (nova), [3] (placement). We're tracking global_request_id ``req-a51f...``. Nova is sending the global_request_id properly in the X-Openstack-Request-Id header, and Placement is receiving it correctly, because it's showing up in the expected spot in the Placement log line (after the opening bracket, per the logging_context_format_string in placement.conf [4]). Placement is sending back the request_id (``req-b3ce...``) in the x-openstack-request-id header in the response. (I thought this was a bug, but it turns out this is correct per the design [5].) So the problem is that the Nova log is printing ``None`` for the global_request_id. Based on logging_context_format_string in nova-cpu.conf [6], I expect it in the first field after the opening bracket, just like for Placement. If the global_request_id were showing up in the Nova log, we wouldn't need to correlate the Nova and Placement sides of this conversation via the Placement request_id, and we could get rid of [0] and its usages. I don't understand how LOG.xxx() is supposed to glean this value. Can someone help me find the disconnect? Thanks, efried [0] https://opendev.org/openstack/nova/src/commit/d358df32f7a2a1125962e27f24253… [1] https://review.opendev.org/#/q/topic:where-are-you-global_request_id [2] http://logs.openstack.org/86/672986/1/check/nova-live-migration/e426c8a/log… [3] http://logs.openstack.org/86/672986/1/check/nova-live-migration/e426c8a/log… [4] http://logs.openstack.org/86/672986/1/check/nova-live-migration/e426c8a/log… [5] https://specs.openstack.org/openstack/oslo-specs/specs/pike/global-req-id.h… [6] http://logs.openstack.org/86/672986/1/check/nova-live-migration/e426c8a/log…

by Budai Laszlo 26 Jul '19

26 Jul '19

Dear all, I am testing different migration scenarios in our openstack, and I ended up with an instance that is running (I can access it by ssh), but its Status is Error. and its task_state is resize_migrating. I suppose that I got here due to the fact that the `allow_resize_to_same_host` is set to True, and the scheduler has tried to use the same compute node in the migration as described here: https://bugs.launchpad.net/nova/+bug/1811235. Is there any possibility to be able to manage again that instance using openstack (except to delete it)? I have tried the shut off (from horizon) and it gives me an error: fault: code: 400 created: '2019-07-26T14:46:05Z' message: Unavailable console type novnc. Thank you, Laszlo

[placement] update 19-29

26 Jul '19

HTML: https://anticdent.org/placement-update-19-29.html Welcome to a rushed pupdate 19-29. My morning was consumed by other things. A reminder: The Placement project holds office hours every Wednesday at 1500 UTC in the `#openstack-placement` IRC channel. If you have a topic that needs some synchronous discussion, then is an ideal time. Just start talking! # Most Important The two main things on the Placement radar are implementing Consumer Types and cleanups, performance analysis, and documentation related to nested resource providers. # What's Changed * The [api-ref](https://docs.openstack.org/api-ref/placement/) has moved to `docs.openstack.org` from `developer.openstack.org`. Redirects are in place. * Both traits and resource classes are [now cached](https://review.opendev.org/672298) per request, allowing for some name to id and id to name optimizations. * A new zuul template is [being used](https://review.opendev.org/671257) in placement that means fewer irrelevant tempest tests are run on placement changes. # Stories/Bugs (Numbers in () are the change since the last pupdate.) There are 21 (-1) stories in [the placement group](https://storyboard.openstack.org/#!/project_group/placement). 0 (0) are [untagged](https://storyboard.openstack.org/#!/worklist/580). 2 (0) are [bugs](https://storyboard.openstack.org/#!/worklist/574). 5 (0) are [cleanups](https://storyboard.openstack.org/#!/worklist/575). 10 (0) are [rfes](https://storyboard.openstack.org/#!/worklist/594). 4 (0) are [docs](https://storyboard.openstack.org/#!/worklist/637).

[openstack-ansible] weekly update
by Mohammed Naser 26 Jul '19

26 Jul '19

Hi everyone, I'm going to try doing these more often to keep everyone updated on the current state of openstack-ansible (mostly around what is discussed during our office hours / meetings). - Dmitriy has been working on removing unused code in playbooks, mostly around logs as we move to 100% systemd-journald. - We're discussing the proposal to remove os-log-dir-setup.yml, as well as rsyslog_client and rsyslog_server roles as they aren’t used anymore with the move to systemd-journald - We're also discussing removing all the complex bind mounts, which would clean it and simplify the code base. - Our continuous integration has been stable but needs upgrade jobs and increased coverage. Our coverage would go up significantly by running aio_lxc for all supported systems. - Jonathan's work on binding to management IPs is making progress (and seems to be at the Galera stage). - CentOS CI has been very slow and nobody knows why. It seems to be something we've regressed at some point. - A unicast flood issue affecting deployments using linuxbridge that happened inside os-vif needs to be patched. It's still pending os-vif to patch. - Namrata mentioned an issue during the upgrade from Rocky to Stein (when upgrading WSREP SST method from xtrabackup-V2 to mariabackup) that will have to be fixed is Stein. That's something that's in progress now. Thanks everyone for reading!

[cinder][ceph][RBD mirroring] Error while creating a mirrored volume
by Ajitha Robert 26 Jul '19

26 Jul '19

Hi all Following picture shows my setup [image: image.png] I m facing following error when i issue a command to enable rbd mirroring on a particular image either manually or through cinder. *"rbd::mirror::InstanceWatcher: C_NotifyInstanceRequest: 0x7fb364025310 finish: resending after timeout"* in rbd-mirroring.log and getting *"failed to get omap key: client_0921b3ce-716a-4462-b3cf-86b5102bfd9"* error in osd.log. . Should I enable anything else apart from timeout parametes, if the distance between the two ceph clusters is greater than 300km? when I create a bootable volume of 100 GB with a glance image.Image get downloaded and from cinder, volume log throws with "volume is busy deleting volume that has snapshot" . Image was enabled with exclusive lock, journaling, layering, object-map, fast-diff and deep-flatten Cinder volume is in error state but the rbd image is created in primary but not in secondary. pls check the logs 1)Log for manual rbd image creation http://paste.openstack.org/show/754766/ 2)Log for 16gb volume created from cinder, status in cinder volume is available http://paste.openstack.org/show/754767/ 3)Log for 100gb volume created from cinder, status in cinder volume is error http://paste.openstack.org/show/754769/ -- *Regards,Ajitha R*

[placement] update 19-27
by Chris Dent 26 Jul '19

26 Jul '19

HTML: https://anticdent.org/placement-update-19-27.html Pupdate 19-27 is here and now. # Most Important Of the features we planned to do this cycle, all are done save one: consumer types (in progress, see below). This means we have a good opportunity to focus on documentation, performance, and improving the codebase for maintainability. You do not need permission to work on these things. If you find a problem and know how to fix it, fix it. If you are not sure about the solution, please discuss it on this email list or in the `#openstack-placement` IRC channel. This also means we're in a good position to help review changes that use placement in other projects. The Foundation needs to know how much, if any, Placement time will be needed in Shanghai. I started a [thread](http://lists.openstack.org/pipermail/openstack-discuss/2019-July/00… and an [etherpad](https://etherpad.openstack.org/p/placement-shanghai-ptg). # What's Changed * The `same_subtree` query parameter has merged as [microversion 1.36](https://docs.openstack.org/placement/latest/placement-api-microversio…. This enables a form of nested provider affinity: "these providers must all share the same ancestor". * The placement projects have been updated (pending merge) to match the [Python 3 test runtimes for Train](https://governance.openstack.org/tc/goals/train/python3-updates.html) community wide goal. Since the projects have been Python3-enabled from the start, this was mostly a matter of aligning configurations with community-wide norms. When Python 3.8 becomes available we should get on that sooner than later to catch issues early. # Specs/Features All placement specs have merged. Thanks to everyone for the frequent reviews and quick followups. Some non-placement specs are listed in the Other section below. # Stories/Bugs (Numbers in () are the change since the last pupdate.)

The changes we are making this cycle are fairly complex to use and are fairly complex to write, so it is good that we're going to have plenty of time to clean and clarify all these things. As mentioned last week, one of the important cleanup tasks that is not yet in progress is updating the [gabbit](https://opendev.org/openstack/placement/src/branch/master/gate/gabb… that creates the nested topology that's used in nested performance testing. The topology there is simple, unrealistic, and doesn't sufficiently exercise the several features that may be used during a query that desires a nested response. This needs to be someone who is more closely related to real world use of nested than me. efried? gibi? Another cleanup that needs to start is satisfying the community wide goal of [PDF doc generation](https://storyboard.openstack.org/#!/story/2006110).

[keystone] Need clarification about Stein policies
by Bernd Bausch 25 Jul '19

25 Jul '19

The Keystone policy.json file I created with oslo-policy-generator contains lines I don't understand. For example /list_users/. The comment says: # DEPRECATED "identity:list_users":"rule:admin_required" has been # deprecated since S in favor of "identity:list_users":"(role:reader # and system_scope:all) or (role:reader and # domain_id:%(target.domain_id)s)". I do understand the expression starting with (role:reader .... , but contrarily to the comment, the policy is "identity:list_users": "rule:identity:list_users" This looks like a circular definition, and in any case, nowhere do I seerule:identity:list_users defined. Can someone in the know explain how this policy is processed? Thanks much, Bernd

[dev][nova][glance][cinder] introducing 'compressed' image container_format
by Ma, Zheng 25 Jul '19

25 Jul '19

Hello Nova developers, Cinder is working on a feature that will allow it to compress volumes uploaded to Glance [0,1]. We are proposing a new container_format for Glance named 'compressed' [2]. The idea is that a consumer of a 'compressed' image would read the file to determine the kind of compression and take appropriate action (either successfully decompress to find a payload that matches the image's disk_format, or fail with 'unsupported container_format'). Our preliminary testing with a raw image with container_format == compressed, disk_format == raw is that Nova boots a VM from the image but the VM appears to be unusable. Nova seems taking it as a real RAW image as disk_format indicates. So we want to open a discussion about handling this. Thanks!

[nova] Train Spec Freeze
by Eric Fried 25 Jul '19

25 Jul '19

Hi Nova contributors and maintainers. Spec freeze for Nova is Thursday, July 25th. This means that any specs not approved by EOD [1] become drastically less likely to land in Train. For your convenience, here is a search that's intended to catch open Train specs while filtering out things like updates to existing specs: https://review.opendev.org/#/q/project:openstack/nova-specs+status:open+pat… At the time of this writing, there are 15 on that list. Of those, IMO two are "close": Add Unified Limits Spec - https://review.opendev.org/602201 - Two +1s, needs review from "Nova API subteam" Spec for the Nova part of Image Encryption - https://review.opendev.org/608696 - +3, needs a second core If you own a spec you think should be able to land [2], please: - Check it to make sure any comments have been addressed (even if there's no -1). - Explicitly ask for reviews, here on the mailing list and/or in IRC in #openstack-nova. Reviewers, please make an effort to ensure that all the specs on that list have at least one vote. (Currently there are six with no vote.) I'll send an update Friday or Monday with a final tally. Thanks, efried [1] i.e. by the time cores have signed off for the day, wherever they are [2] meaning it has already been through some reviews and seems to have support. If you just proposed your spec this week, it's not reasonable to expect it to land.

Heat resource types - aodh and ceilometer
by Dhairyasheel Ghadge 25 Jul '19

25 Jul '19

Hello all, I have installed heat engine along with heat dashboard for orchestration in openstack cloud. I am creating a template to autoscale a web server pool and spin a new VM when load on other one increases. For the autoscaling purpose, I require to have an alarming system which will monitor the cp meter of the instance, which is provided by ceilometer and aodh services of openstack. I cannot find resource types of aodh and ceilometer on the heat dashboard. These same resource types are present in the heat openstack resources directory. Are there any steps to be carried out to make it available on the dashboard? Thanks & Regards Dhairyasheel

[nova] [horizon] Horizon and nova-cli inconsistency in live migration parameters
by Mary Atakova 25 Jul '19

25 Jul '19

Hi everyone, I think I have found an inconsistency between nova cli and Horizon in the way they send live migration commands to nova API. I'm not sure where this needs to be fixed, so please advise on that. The situation: I try to live-migrate a VM, and I do it through nova cli and through Horizon, and nova-api logs contain different data depending on the way I do it. 1. nova cli I run the command: nova live-migration 17359460-d23c-4acc-a9b1-5cf117b54430 and it shows up in nova-api logs as: {"os-migrateLive": {"block_migration": "auto", "host": null}} 2. horizon I run live migration via Horizon with unchecked Disk Overcommit and unchecked Block Migration. It shows up in nova-api logs as: {"os-migrateLive": {"disk_over_commit": false, "block_migration": false, "host": null}} This difference can lead to different parameters provided for live migration when block_migration: auto is translated into block_migration: true. My environment: Openstack Stein CentOS Linux release 7.6.1810 nova versions: # yum list installed | grep nova openstack-nova-api.noarch 1:19.0.1-1.el7 @centos-openstack-stein openstack-nova-common.noarch 1:19.0.1-1.el7 @centos-openstack-stein openstack-nova-conductor.noarch 1:19.0.1-1.el7 @centos-openstack-stein openstack-nova-console.noarch 1:19.0.1-1.el7 @centos-openstack-stein openstack-nova-novncproxy.noarch openstack-nova-placement-api.noarch openstack-nova-scheduler.noarch 1:19.0.1-1.el7 @centos-openstack-stein python2-nova.noarch 1:19.0.1-1.el7 @centos-openstack-stein python2-novaclient.noarch 1:13.0.0-1.el7 @centos-openstack-stein horizon version: # yum list installed | grep dashboard openstack-dashboard.noarch 1:15.1.0-1.el7 @centos-openstack-stein openstack-dashboard-theme.noarch 1:15.1.0-1.el7 @centos-openstack-stein Thank you in advance for your attention Best regards, Mary

[release] (Belated) Release countdown for week R-12, July 22-26
by Kendall Nelson 25 Jul '19

25 Jul '19

Hello Everyone, Development Focus ----------------- The Train-2 milestone is July 25! Train-related specs should now be finalized so that teams can move to implementation ASAP. Some teams observe specific deadlines on the second milestone (mostly spec freezes): please refer to https://releases.openstack.org/train/schedule.html for details. General Information ------------------- Libraries need to be released at least once per milestone period. This week, the release team will propose releases for any library that has not been otherwise released since milestone 1. See list at: http://paste.openstack.org/show/754817/. PTL's and release liaisons, please watch for these and give a +1 to acknowledge them. If there is some reason to hold off on a release, let us know that as well. A +1 would be appreciated, but if we do not hear anything at all by the end of the week, we will assume things are OK to proceed. Remember that non-library deliverables that follow the cycle-with-intermediary release model should have an intermediary release before milestone-2. Those who haven't will be proposed to switch to the cycle-with-rc model, which is more suited to deliverables that are released only once per cycle. This week is also the deadline to freeze the contents of the final release. All new 'Train' deliverables need to have a deliverable file ( https://opendev.org/openstack/releases/src/branch/master/deliverables/train) and need to have done a release by milestone-2. The following new deliverables have not had a release yet (or not been already discussed in the etherpad[1]), and will not be included in Train unless a release is requested for them in the coming week: python-adjutantclient, cyborg-tempest-plugin, neutron-interconnection, openstack-helm, openstack-helm-addons, openstack-help-docs, openstack-helm-images, openstack-helm-infra, and compute-hyperv. The full list of currently deliverable-less deliverables can be found here[2]. Upcoming Deadlines & Dates -------------------------- Train-2 Milestone: July 25 (R-12 week) Thanks! -Kendall Nelson(diablo_rojo) + the Release Management Team [1]https://etherpad.openstack.org/p/train-membership-freeze [2] http://paste.openstack.org/show/754816/

[oslo] PTO next week
by Ben Nemec 24 Jul '19

24 Jul '19

Just a heads up that I will be on PTO next week and incommunicado pretty much the whole time. Moises (moguimar) volunteered to run the Oslo meeting so that will still be happening. Herve (hberaud) and Doug (dhellmann) are our release liaisons so if you need a release of any Oslo libraries next week, they're the ones to talk to. Otherwise, things have been pretty quiet in Oslo-land (which would be Norway, I guess), so I expect all the things to break next week while I'm out. Good luck. ;-) Thanks. -Ben

[ops] [nova] How to change/remove a property from an instance ?
by Massimo Sgaravatto 24 Jul '19

24 Jul '19

In my OpenStack Rocky cloud I have some instances that were created (before updating to Rocky) using images with the property hypervisor_type='qemu'. Since in my compute nodes [libvirt]/virt_type is "kvm", after having updated to Rocky I had to change these images removing that property of changing its value (qemu --> kvm): this is discussed in the thread: http://lists.openstack.org/pipermail/openstack-discuss/2019-July/thread.htm… Now I am not able to migrate anymore the instances that were created using those images (ImagePropertiesFilter filters out all compute nodes) before fixing the property. As suggested by Matt I tried to play with the instance_system_metadata table of the nova database. I first tried to change the value of that property (qemu --> kvm) [*] I also tried to remove the property [**] but the nova migrate keeps failing. In the request I keep seeing that Instance contains properties ImageMetaProps...img_hv_type='qemu' What else needs to be modified?

[opendev] git clone fails: "The TLS connection was non-properly terminated"
by Bernd Bausch 24 Jul '19

24 Jul '19

There seems to be something wrong with the opendev server. Is this a glitch, a daily occurrence (backup?), or a deeper problem? This happens around midnight between July 22 and 23 UTC. $ git clone https://opendev.org/openstack/devstack.git -b stable/stein Cloning into 'devstack'... fatal: unable to access 'https://opendev.org/openstack/devstack.git/': gnutls_handshake() failed: The TLS connection was non-properly terminated. Same result when I try to clone any other random repo. I can get Devstack from Github, but when setting up the cloud, stack.sh wants to clone everything from git.openstack.org, which fails again. I could replace all the hardcoded /git.openstack.org/ strings with the equivalent /github.com/ URL, but I am not sure if I can trust that all Github repos are up to date. Bernd.

Hi, I'm using kolla-ansible stable/rocky release to deploy Openstack Try to test with multi-domains requirements. I'm do nothing but add "horizon_keystone_multidomain: True" into globals.yml After deployment, it works because I have to enter the domain name at login screen. Logged in with default domain and admin account. But I cannot found any "Domains" section in identity block. Is there something I miss?

[keystone] Keystone Train Midcycle Report
by Colleen Murphy 24 Jul '19

24 Jul '19

This week the keystone team conducted a two-day virtual midcycle. Thanks to everyone who participated and contributed to making this a successful and productive meeting! This email will be a short summary of the key takeaways from the last two days. The full agenda and meeting notes can be found on this etherpad: https://etherpad.openstack.org/p/keystone-train-midcycle-topics # Caching Guide We've long been proposing to document best practices for configuring caching for keystone. We began the meeting with a discussion about what exactly should be contained in such a guide, starting with anecdotes from the team about our own operational experience with configuring memcached for keystone. We quickly realized the guide needed at least two parts, one for keystone itself and one for keystonemiddleware. We also made two technical observations, first that the default value for the memcache_socket_timeout option in oslo.cache could be reduced[1] and second that the memcache_socket_timeout option exposed in keystone is not actually used by keystone and needs to be removed[2]. We talked about security strategies for memcached: oslo.cache exposes encryption capabilities which is required for organizations that consider the data stored in memcached to be "at rest", but it also hurts performance. An alternative strategy that could be recommended in the guide is to set up TLS tunneling to secure in-flight data without impeding fetching performance. The initial caching guide update was proposed here[3]. This guide will be a living document and will continue to grow as we gather real-life data from operators. After this initial update, we'll start taking steps to ensure that keystone requires caching be set up in order to operate. [1] https://review.opendev.org/672063 [2] https://bugs.launchpad.net/keystone/+bug/1837407 [3] https://review.opendev.org/672120 # Community Goals We then had a short status update session on the various community goals we need to meet. The mutable config goal from a few cycles ago is not yet complete but has an implementation proposed[4] which needs more eyes and testing. The PDF generation goal implementation is underway[5] but there are some issues already being tracked by the community[6]. We will need to work to ensure the issues we're seeing are noted and addressed. The last of the Python3 Train job changes for keystone repos were merged, so I think we've completed our end of that goal. We also already have a patch proposed to add the ipv6-only job[7] which is just waiting on the base job to merge in tempest.

Some key areas for improvement from this were: * Do more video conferencing - The real-time face-to-face communication is really effective for getting to the heart of discussions and making decisions quickly - Since it is looking likely that most of us will not be at the next PTG in Shanghai, we can set up a pre- and post- PTG video meeting to plan the cycle and catch people up after the IRL PTG - Milestone-ly video meetings are working for helping us keep pace and sync up - We can keep a queue of potential topics and make sure we have a meeting when there are enough topics to discuss - We'll try using video conferencing for office hours - We'll try Jitsi again even though there were some technical issues last time since it is OSS and supports recording * Improve office hours - Office hours still don't feel useful and haven't happened regularly, but we still think they have potential - We'll use the weekly newsletter to commit to the topic the week before, which gives the team a better opportunity to prepare for it and can also attract interest from people outside the keystone team - Use video conferencing as mentioned above * Improve the weekly newsletter - We'll use the weekly newsletter to call out action items from the last meeting - In addition to providing statistics about the number of open reviews, we'll highlight certain reviews that need attention based on various criteria such as age, priority with regard to cycle commitments, community goals, and specific review requests. - We'll announce the following week's office hours topic in the newsletter [8] https://etherpad.openstack.org/p/keystone-train-midcycle-retrospective # System Scope and Default Roles The second day of the midcycle was used to go through our list of open system scope[9] and default roles[10] bugs and work through what scopes and roles each API should support. The notes in the etherpad largely capture every decision fairly well, but a few issues worth highlighting are: * Implied roles[11]: the regular roles API is currently system-scope only, even though it's possible to have domain-specific roles, because for the most part for a role to be useful the role's creator must also have the ability to configure policy, which domain admins do not. Implied roles still require access to policy configuration except in the case where you are only using implied roles for aliasing, in which case it may make sense for a domain admin to have the ability to create an implied role relationship. We decided to start with making the implied roles API system-scope only for now and to open a separate bug to discuss how to deal with domain-specific roles and implied roles. * Revocation list[12]: we're currently not enforcing policy on this API at all because it can only ever return a 410 Gone or a 403 Forbidden, never a success, so we will just deprecate the policy entirely rather than updating it to work with system scope or default roles. We reevaluated the priority on some of the bugs in the list. However, we noted that while some APIs are more heavily used than others, we can't change enforce_scope to True until all of them are completed - picking and choosing the most important ones and letting the others slide is not really an option. [9] https://bugs.launchpad.net/keystone/+bugs?field.tag=system-scope [10] https://bugs.launchpad.net/keystone/+bugs?field.tag=default-roles [11] https://bugs.launchpad.net/keystone/+bug/1805371 [12] https://bugs.launchpad.net/keystone/+bug/1818845 If I've left out any important details, don't hesitate to add them to this thread. Thanks again to everyone who was able to join the meeting! Thanks also to Julia Kreger for her advice on how to hold one of these virtual midcycles, it proved to be very useful and this first-timer really appreciated it :) Colleen

[tripleo] CI scenario001-standalone broken
by John Fulton 24 Jul '19

24 Jul '19

As per $subject [0]. scenario010 is affected too. This correlates with the promotion of the ceph-ansible 4rc11 RPM [1]. 001 jobs using rc9 do not have this problem. I'm looking into a fix, e.g. removing the storage7-ceph-nautilus-release tag from the rc11 package as TripleO CI uses the version of ceph-ansible which is tagged for release [2]. I'll keep this thread updated with the status and when it's fixed.

[Diversity] Grace Hopper Lead Co-Mentor(s) needed
by Amy Marrich 23 Jul '19

23 Jul '19

OpenStack has participated in Open Source Day at the Grace Hopper Conference for the last 5 years and this year it is in Orlando on October 3rd. Due to unforeseen circumstances we are one lead mentor short to participate this year and are looking for someone willing to help lead the session. The Anita Borg Institute will provide a ticket for the entire conference, the downside is you or your company will be responsible for your travel, lodging and food. This year CityNetwork is supplying the VM infrastructure for us to use. The session submitted is as follows: Participants will sign up for the necessary accounts needed to contribute to OpenStack and install Git and Gerrit. They will configure their systems and learn how to file bugs and review code within the Open Dev infrastructure. Due to time and resource requirements the groups will be given a virtual machine running Devstack in which to create their own theme for the Horizon Dashboard. The group will decide on which humanitarian effort they wish to support but suggestions will be provided for those groups that can not decide. The group will also work as a team to locate the necessary documentation on the OpenStack site if they have not done so in preparation. The selected Project Manager will lead these discussions as well as making sure efforts are staying on track to meet the deadline of the demonstrations. The Developers in the group will work to locate the necessary files and directories on the VM in order to complete their task. They will be in charge of creating/changing the necessary files to create a new theme utilizing SCSS and restarting any services needed to implement. The Graphic Designer if present will create any necessary graphics for the theme and will either scp them themselves to the virtual machine or provide to the developer. If there is no designated graphic designer the PM and devs will divide this duty up. After the themes are designed relevant files will be scped back down to the participants machines and they will be able to commit their code for review in a sandbox environment for other groups to review. If you are interested in participating please let me know by July 20th as we need to send additional information to the OSD folks on July 21st. Any questions please reach out on the lists, IRC, or privately! Thanks, Amy (spotz)

[Octavia]-Seeking performance numbers on Octavia
by Singh, Prabhjit 23 Jul '19

23 Jul '19

Hi I have been trying to test Octavia with some traffic generators and my tests are inconclusive. Appreciate your inputs on the following * It would be really nice to have some performance numbers that you guys have been able to achieve for this to be termed as carrier grade. * Would also appreciate if you could share any inputs on performance tuning Octavia * Any recommended flavor sizes for spinning up Amphorae, the default size of 1 core, 2 Gb disk and 1 Gig RAM does not seem enough. * Also I noticed when the Amphorae are spun up, at one time only one master is talking to the backend servers and has one IP that its using, it has to run out of ports after 64000 TCP concurrent sessions, id there a way to add more IPs or is this the limitation * If I needed some help with Octavia and some guidance around performance tuning can someone from the community help Thanks & Regards Prabhjit Singh

[ironic] Using ironic in a devstack environment to deploy OS on bare-metal host.
by Guannan GN2 Sun 23 Jul '19

23 Jul '19

Hi team, I met some problem when using ironic in a devstack environment to deploy OS on bare-metal host. By now I can successfully boot into the tiny os and set ip, also I can ping the ip from my devstack server. However, when the tiny os running some configuration, it will failed after about 5 minutes. I found some log information in "/var/log/ironic-python-agent.log" in the tiny os that may relate to the problem: "DEBUG oslo_concurrency.processutils [-] u'iscsistart -f' failed. Not Retrying. execute /usr/local/lib/python2.7/site-packages/oslo_concurrency/processutils.py:457" "DEBUG root [-] No iscsi connection detected. Skipping iscsi. Error: [Errno 2] No such file or directory _check_for_iscsi /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware.py:107" "WARNING root [-] The root device was not detected in 27 seconds: DeviceNotFound: Error finding the disk or partition device to deploy the image onto: No suitable device was found for deployment - root device hints were not provided and all found block devices are smaller than 4294967296B." "WARNING root [-] Can't find field vendor for device usb0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/usb0/device/vendor'" "WARNING root [-] Can't find field vendor for device tunl0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/tunl0/device/vendor'" "DEBUG root [-] No Mellanox devices found evaluate_hardware_support /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware_managers/mlnx.py:84" And when it deploy faild and I run command "openstack baremetal node show server-51", it will show following information on 'last_error' field: "Asynchronous exception: Node failed to deploy. Exception: Connection to agent failed: Failed to connect to the agent running on node f8794658-bc69-40cb-9673-be75f78ced21 for invoking command iscsi.start_iscsi_target.

[dev][magnum] Magnum event notifications not having relevant content related to clusters
by Emnauel Andrecut 23 Jul '19

23 Jul '19

I'm writing about Magnum event notifications that do not contain any relevant information about the related Cluster (missing cluster id, other attributes..) As I've seen the PyCADF library receives no targetId and so the id (and mostly any other id) is randomly generated. Do you plan to add more information about the cluster on create success/pending events. Or would you accept a patch that does that?

[all][meta-sig][containers-sig] Creation of Containers SIG
by Jean-Philippe Evrard 23 Jul '19

23 Jul '19

Hello everyone, I have discussed with some of you about the fact OpenStack is lacking a a group interested in sharing the practices for the building/management of OpenStack application containers. Every container related project is doing its own way (and it's probably fine), but very few experiences are shared (and it's sad). I started an etherpad [1] to see areas where container projects/people could collaborate. I already received significant feedback on how to improve some of my practices, so I think it's already a positive experience for me to have this group started. Anyway, long story short, I believe we should create a SIG for this, so I proposed the addition of the containers-sig into governance [2]. We have enough work to started this group nowadays (with documentation, bindep shared practices, and improvement of projects). I suppose technologies will evolve over time, so I expect a SIG is the best tool to do this job of *for example* gathering experience, as it's not really time bound, and it _is_ a quite special interest. If you're interested by learning what is going on in the container building world for OpenStack, please add [containers-sig] to your openstack-discuss topics watch list. Regards, Jean-Philippe Evrard (evrardjp) [1]: https://etherpad.openstack.org/p/containers-sig [2]: https://review.opendev.org/#/c/666001/

[nova] FYI to out-of-tree drivers: adding a positional argument to finish_revert_migration()
by Artom Lifshitz 23 Jul '19

23 Jul '19

[1] will most likely merge in its current shape or something very close to it. It adds a `migration` positional argument to the finish_revert_migration() virt driver method. `migration` is the, err, migration that's being reverted. If you have out of tree virt drivers, please update them to match this new method signature. Thanks! [1] https://review.opendev.org/#/c/668631/

[tripleo] TripleO CI Summary: Sprint 33
by Rafael Folco 22 Jul '19

22 Jul '19

Greetings, The TripleO CI team has just completed Sprint 33 / Unified Sprint 12 (Jun 27 thru Jul 17). The following is a summary of completed work during this sprint cycle: - Tested check jobs for periodic image/container builds on RHEL8 and resolved its dependencies on rhui repositories. - Enabled tripleo-repos to support RHEL8. - Addressed changes in kolla to support RHEL8. - Created a nodepool image on RDO for RHEL8 w/ elements and dependencies installed. - Improved container build script to consolidate kolla build logs and ease troubleshooting. - Manually pushed rhel containers to RDO registry and identified gaps in authentication workflow for the container build jobs using buildah tooling. - Modified scripts and post playbooks to upload RHEL8 overcloud images. - Created RHEL8 jobs to build a periodic pipeline in the RDO Software Factory and provide feedback for CentOS8 coverage. - Resumed scenario007 and featureset039 job updates upstream. - Promotion status: green on all branches at most of the sprint. The planned work for the next sprint [1] are: - Get RDO on RHEL8 build jobs working in periodic pipeline and bootstrap standalone and featureset001 jobs to consume RHEL8 images/containers. - Get featureset039 job to run novajoin tests and merge scenario007 job changes. - Review templates for branched and non-branched projects to have more control on what jobs are being run and reduce queue lengths. - Resume the design work for a staging environment to test changes in the promoter server for the multi-arch builds. The Ruck and Rover for this sprint are Marios Andreou (marios) and Rafael Folco (rfolco). Please direct questions or queries to them regarding CI status or issues in #tripleo, ideally to whomever has the ‘|ruck’ suffix on their nick. Ruck/rover notes are being tracked in etherpad [2]. Thanks, rfolco [1] https://tree.taiga.io/project/tripleo-ci-board/taskboard/unified-sprint-13 [2] https://etherpad.openstack.org/p/ruckroversprint13
