by Ignazio Cassano 14 May '21

14 May '21

Hello, I have a problem on stein neutron. When a vm migrate from one node to another I cannot ping it for several minutes. If in the vm I put a script that ping the gateway continously, the live migration works fine and I can ping it. Why this happens ? I read something about gratuitous arp. Please, help me ? Any workaround , please ? Best Regards Ignazio

I'm bringing this up because we have https://review.openstack.org/#/c/647009/ which is for the upcoming rename but CI is broken and we have no interest in continue to keep the stable/ocata branches alive (or fix ci for them).

I believe it started after we upgraded to the Stein release. I haven't tracked it down yet, but calls to the YAQL function: std:Project.getEnvironmentOwner() in a Murano app seem to generate it.

If you change the network with "create new" parameter, it stuck on "creating -or updating- environment" state and after that throws connection error. So i searched Murano network errors and i found this: https://docs.oracle.com/cd/E73172_01/E73173/html/issue-21976631.html. I applied these steps and i created successfully an environment just only with "create new" network parameter. After all these, i realized my devstack environment has no internet connection and because of this murano-agent could not install. So i tried to install Murano on my OSA stable/train test environment and i came with success until last step. Murano-agent installed but this time agent could not connect to rabbitmq instance. I discussed this with OSA IRC channel and i think i have to struggle with this for a long time. Apologize for this long mail but i wanted to inform you. Thanks.

I think you've probably just worked around the issue. Using your new method, you're probably just avoiding the std:Project.getEnvironmentOwner YAQL call now. I've also worked around it in our environment, but I'd like to solve it properly. When I get some time to look into it properly, I'll let you know. cheers, Andy

[ceilometer][octavia] polling meters
by Ionut Biru 14 Jul '20

14 Jul '20

Hello guys, I was trying to add in polling.yaml and pipeline from ceilometer the following: - network.services.lb.active.connections - network.services.lb.health_monitor - network.services.lb.incoming.bytes - network.services.lb.listener - network.services.lb.loadbalancer - network.services.lb.member - network.services.lb.outgoing.bytes - network.services.lb.pool - network.services.lb.total.connections But it doesn't work, I think they are for the old lbs that were supported in neutron. I found https://docs.openstack.org/ceilometer/latest/admin/telemetry-dynamic-pollst… but this is not available in stein or train. I was wondering if there is a way to meter loadbalancers from octavia. I mostly want for start to just meter if a loadbalancer was deployed and has status active. -- Ionut Biru - https://fleio.com

[all][stable] Moving the stable/ocata to 'Unmaintained' phase and then EOL
by Ghanshyam Mann 02 Jul '20

02 Jul '20

Hello Everyone, Ocata is in the 'Extended Maintenance' phase[1] but its gate is broken and difficult to fix now. The main issue started for gate is about Tempest and its deps constraint is correctly used on Ocata or not. We fixed most of those issues when things started failing during py2 drop[2]. But now things are broken due to newer stestr is installed in Ocata jobs[2]. As Sean also mentioned in this backport[4] that stestr is not constraint in Ocata[5] as it was not in g-r that time so cannot be added in u-c. Tempest old tag cannot be fixed to have that with cap on the tempest side. The only option left to unblock the gate is to remove the integration testing from Ocata gate. But it will untested after that as we cannot say unit testing is enough to mark it tested. At least from QA perspective, I would not say it is tested if there is no integration job running there. Keeping it untested (no integration testing) and saying it is Maintained in the community can be very confusing things. I think its time to move it to the 'Unmaintained' phase and then EOL. Thought?

[tc][election] campaign discussion: how TC can solve the less contributor issue?
by Ghanshyam Mann 23 Jun '20

23 Jun '20

This topic is a very important and critical area to solve in the OpenStack community. I personally feel and keep raising this issue wherever I get the opportunity. To develop or maintain any software, the very first thing we need is to have enough developer resources. Without enough developers (either open or closed source), none of the software can survive. OpenStack current situation on contributors is not the same as it was few years back. Almost every project is facing the less contributor issue as compare to requirements and incoming requests. Few projects already dead or going to be if we do not solve the less contributors issue now. I know, TC is not directly responsible to solve this issue but we should do something or at least find the way who can solve this. What do you think about what role TC can play to solve this? What platform or entity can be used by TC to raise this issue? or any new crazy Idea? -gmann

Openstack user surver - questions
by Slawek Kaplonski 17 Jun '20

17 Jun '20

Hi, First of all sorry if I didn't look for it long enough but I have couple of questions about user surver and I couldn't find answer for them anywhere. 1. I was looking at [1] for some Neutron related data and I found only one questions about used backends in "Deployment Decisions". Problem is that this graph is for me a bit unreadable due to many things on x-axis which overlaps each other. Is there any place where I can find some "raw data" to check? 2. Another question about the same chart is: is there any way to maybe change possible replies in the surver for next years? I'm asking about that becasue I have a feeling that e.g. responses "Open vSwitch" and "ML2 - Open vSwitch" may be confusing for users. My understanding is that "Open vSwitch" means simply old "Open vSwitch" core plugin instead of ML2 plugin but this old plugin was removed around "Libery" cycle so I really don't think that still 37% of users are using it. 3. Is there any way to propose new, more detailed questions about e.g Neutron? For example what service plugins they are using.

[tc][uc][all] Starting community-wide goals ideas for V series
by Ghanshyam Mann 15 Jun '20

15 Jun '20

Hello everyone, We are in R14 week of Ussuri cycle which means It's time to start the discussions about community-wide goals ideas for the V series. Community-wide goals are important in term of solving and improving a technical area across OpenStack as a whole. It has lot more benefits to be considered from users as well from a developers perspective. See [1] for more details about community-wide goals and process. We have the Zuulv3 migration goal already accepted and pre-selected for v cycle. If you are interested in proposing a goal, please write down the idea on this etherpad[2] - https://etherpad.openstack.org/p/YVR-v-series-goals Accordingly, we will start the separate ML discussion over each goal idea. Also, you can refer to the backlogs of community-wide goals from this[3] and ussuri cycle goals[4]. NOTE: TC has defined the goal process schedule[5] to streamlined the process and ready with goals for projects to plan/implement at the start of the cycle. I am hoping to start that schedule for W cycle goals.

[all][infra] Upcoming removal of preinstalled pip and virtualenv from base images
by Ian Wienand 15 Jun '20

15 Jun '20

Hello, This is to notify the community of the planned upcoming removal of the "pip-and-virtualenv" element from our infra image builds. This is part of the "cleanup test node python" spec documented at [1]. tl;dr ----- - pip and virtualenv tools will no longer be pre-installed on the base images we use for testing, but will be installed by jobs themselves. - most current jobs will depend on common Zuul base jobs that have been updated to install these tools already *i.e. in most cases there should be nothing to do* - in general, jobs should ensure they depend on roles that install these tools if they require them - if you do find your job failing due to the lack of either of these tools, use the ensure-pip or ensure-virtualenv roles provided in zuul-jobs - we have "-plain" node types that implement this now. If you think there might be a problem, switch the job to run run against one of these node types described below for testing. History ------- The "pip-and-virtualenv" element is part of diskimage-builder [2] and installs the latest version of pip and virtualenv, and related tools like setuptools, into the system environment for the daily builds. This has a long history of working around various issues, but has become increasingly problematic to maintain. One of the more noticable effects is that to prevent the distribution packages overwriting the upstream installs, we put various pip, setuptools and virtualenv packages on "hold" in CI images. This prevents tests resinstalling packaged tools which can create, in short, a big mess. Both destroying the extant environment and having the tools on hold have been problems for various projects at various times. Another other problem is what happens when you call "pip" or "virtualenv" has diverged. It used to be that "pip" would install the package under Python2, while pip3 would install under python3. However, modern distributions now have "pip" installing under Python 3. To keep having "pip" install Python 2 packages on these platforms is not just wrong, but drags in Python 2 dependences to our images that aren't required. The addition of Python 3's venv and the split with virtualenv makes things even more confusing again. Future ------ As famously said "the only winning move is not to play". [3] By dropping this element, images will not have non-packaged pip/virtualenv/setuptools/etc. pre-installed. No packages will be on hold. The "ensure-pip" role [4] will ensure that dependencies for "pip:" commands will work. Because of the way base jobs are setup, it is most likely that this role has already run. If you wish to use a virtual environment to install a tool, I would suggest using the "ensure_pip_virtualenv_cmd" this role exports. This will default to "python3 -m venv". An example is [5]. In a Python 3 word, you probably do not *need* virtualenv; "python3 -m venv" is available and works after the "ensure-pip" role is run. However, if you require some of the features that virtualenv provides that venv does not (explained at [6]) there is a role "ensure-virtualenv" [7]. For example, we do this on the devstack branches because it is common to use "virtualenv" there due to the long history [8]. If you need specific versions of pip or virtualenv, etc. beyond the system-packaged versions installed with the above, you should have your job configure these. There is absolutely no problem with jobs installing differing versions of pip/virtuatlenv/etc in any way they want -- we just don't want the base images to have any of that by default. Of course, you should consider if you're building/testing something that is actually useful outside the gate, but that is a global concern. Testing ------- We have built parallel nodes with the suffix "-plain" where you can test any jobs in the new environment. For example [9] speculatively tests devstack. The node types available are centos-7-plain centos-8-plain ubuntu-xenial-plain ubuntu-bionic-plain The newer focal images do not have pip pre-installed, neither do the faster moving Fedora images, any SUSE images, or any ARM64 images. Rollout ------- We would like to make the switch soon, to shake out any issues early in the cycle. This would mean on or about the 8th June.

Hi, I need to book slots for nova discussions on the official schedule[2] of the virtual PTG[1]. I need two things to do that: 1) What topics we have that needs real-time discussion. Please add those to the etherpad [3] 2) Who wants to join such real-time discussion and what time slots works for you. Please fill the doodle[4] Based on the current etherpad content we need 2-3 slots for nova discussion and a half slot for cross project (current neutron) discussion. Please try to provide your topics and options before the Thursday's nova meeting.

[nova][neutron][ptg] How to increase the minimum bandwidth guarantee of a running instance
by Balázs Gibizer 05 Jun '20

05 Jun '20

Hi, [This is a topic from the PTG etherpad [0]. As the PTG time is intentionally kept short, let's try to discuss it or even conclude it before the PTG] As a next step in the minimum bandwidth QoS support I would like to solve the use case where a running instance has some ports with minimum bandwidth but then user wants to change (e.g. increase) the minimum bandwidth used by the instance. I see two generic ways to solve the use case: Option A - interface attach --------------------------- Attach a new port with minimum bandwidth to the instance to increase the instance's overall bandwidth guarantee. This only impacts Nova's interface attach code path: 1) The interface attach code path needs to read the port's resource request 2) Call Placement GET /allocation_candidates?in_tree=<compute RP of the instance> 3a) If placement returns candidates then select one and modify the current allocation of the instance accordingly and continue the existing interface attach code path. 3b) If placement returns no candidates then there is no free resource left on the instance's current host to resize the allocation locally. Option B - QoS rule update -------------------------- Allow changing the minimum bandwidth guarantee of a port that is already bound to the instance. Today Neutron rejects such QoS rule update. If we want to support such update then: * either Neutron should call placement allocation_candidates API and the update the instance's allocation. Similarly what Nova does in Option A. * or Neutron should tell Nova that the resource request of the port has been changed and then Nova needs to call Placement and update instance's allocation. The Option A and Option B are not mutually exclusive but still I would like to see what is the preference of the community. Which direction should we move forward? Both options have the limitation that if the instance's current host does not have enough free resources for the requested change then Nova will not do a full scheduling and move the instance to another host where resource is available. This seems a hard problem to me. Do you have any idea how can we remove / ease this limitation without boiling the ocean? For example: Does it make sense to implement a bandwidth weigher in the scheduler so instances can be spread by free bandwidth during creation?

[nova][neutron][ptg] Future of the routed network support
by Balázs Gibizer 05 Jun '20

05 Jun '20

Hi, [This is a topic from the PTG etherpad [0]. As the PTG time is intentionally kept short, let's try to discuss it or even conclude it before the PTG] There is only basic scheduling support in nova for the neutron routed networks feature (server create with port.ip_allocation=deferred seems to work). There was multiple attempts in the past to complete the support (e.g.server create with port.ip_allocation=immediate or server move operations). The latest attempt started by Matt couple of cycles ago, and in the last cycle I tried to push that forward[1]. When I added this topic to the PTG etherpad I thought I will have time in the Victoria cycle to continue [1] but internal priorities has changed. So finishing this feature needs some developers. If there are volunteers for Victoria then please let me know and then we can keep this as a topic for the PTG but otherwise I will remove it from the schedule.

[nova][ptg] bumping compute RPC to 6.0
by Balázs Gibizer 05 Jun '20

05 Jun '20

Hi, [This is a topic from the PTG etherpad [0]. As the PTG time is intentionally kept short, let's try to discuss it or even conclude it before the PTG] Do we want to bump the compute RPC to 6.0 in Victoria? We did not have the full view what we can gain[2] with such bump so Stephen and I searched through nova and collected the things we could clean up [1] eventually if we bump the compute RPC to 6.0 in Victoria. I can work on the RPC 6.0 patch during V and I think I can also help in with the possible cleanups later.

[nova][ptg] Runway process in Victoria
by Balázs Gibizer 04 Jun '20

04 Jun '20

Hi, [This is a topic from the PTG etherpad [0]. As the PTG time is intentionally kept short, let's try to discuss it or even conclude it before the PTG] In the last 4 cycles we used a process called runway to focus and timebox of the team's feature review effort. However compared to the previous cycles in ussuri we did not really keep the process running. Just compare the length of the Log section of each etherpad [1][2][3][4] to see the difference. So I have two questions: 1) Do we want to keep the process in Victoria? 2) If yes, how we can make the process running? 2.1) How can we keep the runway etherpad up-to-date? 2.2) How to make sure that the team is focusing on the reviews that are in the runway slots? Personally I don't want to advertise this process for contributors if the core team is not agreed and committed to keep the process running as it would lead to unnecessary disappointment.

[cyborg][nova][neutron]Summaries of Smartnic support integration
by yumeng bao 03 Jun '20

03 Jun '20

Hi all, In cyborg pre-PTG meeting conducted last week[0],shaohe from Intel introduced SmartNIC support integrations,and we've reached some initial agreements: The workflow for a user to create a server with network acceleartor(accelerator is managed by Cyborg) is: 1. create a port with accelerator request specified into binding_profile field NOTE: Putting the accelerator request(device_profile) into binding_profile is one possible solution implemented in our POC. Another possible solution,adding a new attribute to port object for cyborg specific use instead of using binding_profile, is discussed in shanghai Summit[1].

[all] Week Out PTG Details & Registration Reminder
by Kendall Nelson 03 Jun '20

03 Jun '20

Hello Everyone! We are so excited to see you next week at our first virtual PTG! Below are all the details you need to have a fun and successful event. First and foremost: PLEASE REGISTER; https://virtualptgjune2020.eventbrite.com/ If you don't register for the event, we have no way of sending you information about the event, specifically the passwords that we will have set on the zoom rooms. Registration is free. =Final Schedule= The final schedule for the event is available here[1] and in the PTGBot[2]. =Tooling & Passwords= For each virtual PTG meeting room, we will provide an official Zoom videoconference room, which will be reused by various groups across the day. Please make sure to leave the room at the end of your team meeting! We will be setting passwords on the rooms to prevent vandalism/harassment, and we will send those out 24 hours before the start of the event. OpenDev's Jitsi Meet instance is also available at https://meetpad.opendev.org as an alternative tooling option to create team-specific meetings. This is more experimental and may not work as well for larger groups, but has the extra benefit of including etherpad integration (the videoconference doubles as an etherpad document, avoiding jumping between windows). PTGBot can be used to publish the chosen meeting URL if you decide to not use the official Zoom one. The OpenDev Sysadmins can be reached in the #opendev IRC channel if any problems arise. We recommend you try out Zoom and Meetpad ahead of the PTG to solve audio/video issues. =IRC= The main form of synchronous communication between attendees during the PTG is on IRC. If you are not on IRC, learn how to get started here [3]. The main PTG IRC channel is #openstack-ptg on Freenode, and it's used to interact with the PTGbot. The OpenStack Foundation (OSF) staff will be present to help answer questions. =PTGbot= The PTGbot[2] is an open source tool that PTG room moderators use to surface what's currently happening at the event. Room moderators will send messages to the bot via IRC, and from that information the bot publishes a webpage with several sections of information: - The discussion topics currently discussed in the room ("now") - An indicative set of discussion topics coming up next ("next") - The schedule for the day with available extra slots you can book Learn more about the PTGbot via the documentation here [4]. =Help Desk= We are here to help! If you have any questions during the event week, we will have a dedicated Zoom room where an OSF staff member will be available to answer your event related questions. If a staff member is not there to help, you can always reach someone at ptg(a)openstack.org or on IRC in the #openstack-ptg channel. =Feedback= We have created an etherpad[5] to collect all of your feedback throughout the event. Please add your thoughts so we can continue improving our virtual events! =Virtual Event Best Practices= Check out our list of virtual event best practices[6] prior to the event to help make the most of your time at the PTG. =Code of Conduct= The PTG is for everyone. We have zero tolerance for harassment and other violations of the OSF Community Code of Conduct. Before the PTG begins, please review the Code of Conduct[7] and know how to report an issue. -The Kendalls (diablo_rojo & wendallkaters) [1] Schedule: https://www.openstack.org/ptg#tab_schedule [2] Live PTGBot: http://ptg.openstack.org/ptg.html [3] IRC Setup: https://docs.openstack.org/contributors/common/irc.html [4] PTGBot Documentation: https://github.com/openstack/ptgbot/blob/master/README.rst [5] Feedback Etherpad: https://etherpad.opendev.org/p/June2020-PTG-Feedback [6] PTG Best Practices: https://etherpad.opendev.org/p/virtual-ptg-best-practices [7] Code of Conduct: https://www.openstack.org/legal/community-code-of-conduct/

[cinder] [ironic] Any update on Cinder Ceph ISCSI Driver?
by kevinz 02 Jun '20

02 Jun '20

Hi Cinder, We are looking forward to the IRONIC boot from Cinder Ceph Volume. I went through the mailist and found the conversation last year, the main gap for the Ironic boot from Cinder volume(Ceph BACKEND) is lacking Cinder Ceph iscsi driver. http://lists.openstack.org/pipermail/openstack-discuss/2019-May/006041.html So I'm sending to ask the current status for this. We are from Linaro, all our machines are under Ironic and we use Ceph as backend storage. Recently we are looking at the Diskless server boot plan from the Ceph cluster. Any info or update or advice, I really appreciate it. Look forward to hearing from you.

[cinder][security] propose Rajat Dhasmana for cinder coresec
by Brian Rosmaita 02 Jun '20

02 Jun '20

Jay Bryant is stepping down from the Cinder core security team due to time constraints. I am proposing to replace him with Rajat Dhasmana (whoami-rajat on IRC). Rajat is has been a cinder core since January 2019 and is a thorough and respected reviewer and developer. Additionally, he'll extend our time zone coverage so that there will always be someone available to review/work on security patches around the clock. I intend to add Rajat to cinder coresec on Tuesday, 2 June; please communicate any concerns to me before then. cheers, brian
