It's time to submit your OpenStack User Survey
by Allison Price 20 Aug '21

20 Aug '21

Hi everyone, Here’s my annual email requesting you complete the OpenStack User Survey [1] and share with your local communities / community friends who are operating OpenStack. Anonymous reposes and aggregated data from the User Survey are shared with the OPenStack PTLs and overall community to help understand operator software requirements. If you have never taken it before, please do! We welcome your feedback and I am happy to answer any questions you may have. If you are one of the many who have, all of your previous information should be stored, so you will just need to provide updates where relevant and re-save. Thank you all! Cheers, Allison [1] https://www.openstack.org/user-survey/survey-2021 <https://www.openstack.org/user-survey/survey-2021> Allison Price Director of Marketing & Community OpenInfra Foundation e: allison(a)openstack.org <mailto:allison@openstack.org>

[masakari] Compute service with name XXXXX not found.
by at 19 Aug '21

19 Aug '21

Hi, I have some problem with masakari. I can create segment (from CLI and Horizon), but can't create host (the same result from Horizon and CLI). openstack segment host create XXXXX COMPUTE SSH segment_id returns BadRequest: Compute service with name XXXXX could not be found. XXXXX is the name which Horizon suggest, and it's a name of compute host. openstack compute service list returns proper list with state up/enabled on compute hosts (zone nova) Maybe I misunderstood some parameters of host create? As "type" I use COMPUTE, what value should it be? From "Binary" column of openstack compute service list? What is "control_attributes" field, because documentation lacks preceise information what value should be there and what is it use for. Tried to found some info on this error but I haven't found anything... Thanks in advance for any help. Best regards Adam Tomas

[tc][all] Please Help On Collecting Pain Points
by Rico Lin 16 Aug '21

16 Aug '21

Dear all As a proposal for pre-select goals for Yoga [1]. We need to figure out the possibility. *I would like to ask each project team, SIG, and pop-up if you can kindly provide the major pain point you have (and better to be fixable by bugs/features).* *What you can help with is added in pain point information in [2].* *Information like pain point topic, description, and ideas on how to targeting them.* *Why this is important?* I think this data allows us to see clearly if we can have goals like `eliminate pain points`. *What's after this?* If we can make sure this can be a goal material, we might be able to have this as a goal and allow project teams to focus on one of their most important issues. As an alternative, we might be able to collect from user side with a user survey, but that's more like a really long-term plan for this.

Pls help newbie :) bare metal new Ansible deployment
by Nicola Ferrari (#554252) 14 Aug '21

14 Aug '21

Dears, I'm new to the list. We're just trying to introduce a demo install of openstack in our network. Our intention was to use 5 machine, already installed with ubuntu-mini 20.04. ostack1 as control node ostack2 -| ostack3 -| AS COMPUTE NODE ostack4 -| ostack5 -| ostack4 - ostack5 also as block storage node, they are connected on a direct storage (sas) where we deployed lvm with a vg named "cinder_volumes". All nodes both are on a /24 network (192.168.32.0/24) behind a router (32.254) and also on a "private" network (10.255.255.0/24) which just interconnect nodes themselves. We inteded to deploy openstack using openstack-ansible, available on github, last stable release. You can see our user_config as attachment. setup-hosts playbook runs with no errors. setup-infrastructure playbook hangs on RUNNING HANDLER [repo_server : reload nginx] **************************************************************************************** FAILED - RETRYING: reload nginx (1 retries left). fatal: [ostack1_repo_container-aabb6a12]: FAILED! => {"attempts": 5, "changed": false, "msg": "Unable to start service nginx: Job for nginx.service failed because the control process exited with error code.\nSee \"systemctl status nginx.service\" and \"journalctl -xe\" for details.\n"} Looking at log I can see that nginx coudn't start due to "Cannot assign requested address: 99" error. I suppose that must be a mistake in the deploy file? Many thanks for your suggestion, and pls, be sorry for my poor english :) Nick

[neutron] Status of networking-mlnx: Is it still maintained ?
by Takashi Kajinami 12 Aug '21

12 Aug '21

Hello, I noticed the networking-mlnx repo[1] is not updated for a while and looks unmaintained. The repo doesn't have a stable/wallaby release created, and its setup.cfg doesn't include python 3.8 as a supported platform. https://opendev.org/x/networking-mlnx Is anybody still maintaining this repo ? If the repo is no longer maintained, I'll propose deprecating support for the plugin from puppet-neutron. Please let me know if you have any concern with that deprecation. I appreciate any input about this $topic. Thank you, Takashi Kajinami

[PTLs][release] Xena Cycle Highlights
by helena＠openstack.org 12 Aug '21

12 Aug '21

Hello Everyone!It's that time of the year once again! It's time to start thinking about calling out 'cycle-highlights' in your deliverables! As PTLs, you probably get many pings towards the end of every release cycle by various parties (marketing, management, journalists, etc) asking for highlights of what is new and what significant changes are coming in the new release. By putting them all in the same place it makes them easy to reference because they get compiled into a pretty website like this from the last few releases: Ussuri[1], Victoria[2]. We don't need a fully fledged marketing message, just a few highlights (3-4 ideally), from each project team. Looking through your release notes might be a good place to start. The deadline for cycle highlights is the end of the R-5 week [3] on September 3.How To Reminder: -------------------------Simply add them to the deliverables/$RELEASE/$PROJECT.yaml in the openstack/releases repo like this: cycle-highlights: - Introduced new service to use unused host to mine bitcoin.The formatting options for this tag are the same as what you are probably used to with Reno release notes.Also, you can check on the formatting of the output by either running locally: tox -e docsAnd then checking the resulting doc/build/html/$RELEASE/highlights.html file or the output of the build-openstack-sphinx-docs job under html/$RELEASE/highlights.html. Feel free to add Kendall Nelson (diablo_rojo) as a reviewer on your patches. Can't wait to see you all have accomplished this release! Thanks :) -Helena Spease (hspease) [1] [ https://releases.openstack.org/ussuri/highlights.html ]( https://releases.openstack.org/ussuri/highlights.html ) [2] https://releases.openstack.org/victoria/highlights.html [3] https://releases.openstack.org/xena/schedule.html

[interop][cinder] review of next.json (part 2)
by Brian Rosmaita 09 Aug '21

09 Aug '21

Hello Interop WG, The Cinder team completed its discussion of what capabilities should be added as advisory in next.json at yesterday's weekly cinder meeting [0]. The tldr; is that we don't have anything to propose for inclusion in next.json at the present time. The team does have some general questions that would help us determine the suitability of some proposed capabilities. We'd like to invite someone from the Interop WG to the cinder xena R-9 virtual midcycle (Wednesday 4 August 2021, 1400-1600 UTC) so we can discuss this "live". So if someone could put 1400 UTC 4 August on their schedule for a 20 minute discussion, that would be very helpful. cheers, brian [0] http://eavesdrop.openstack.org/meetings/cinder/2021/cinder.2021-05-12-14.00…

Re: [neutron-vpnaas][kolla-ansible][victoria] Growing memory consumption with only one VPN connection
by at 09 Aug '21

09 Aug '21

Hi, 1. There is only one, bidirectional vpn connection between project networks in two regions 2. there is no (or almost no) traffic on this vpn link 3. second region is on one host (kolla all-in-one) and situation looks the same- with vpn service enabled there is excessive Memory use (growing also about 5-6MB/ minute and forcing the system to use swapfile) there is no big cpu usage (ofcourse also due to no traffic inside VPN) It's the same case even if there's no vpn connection configured.

I was able to create VPN connection and communication is correct. But after a week of running vpnaas (only one VPN connection created/working!)

[neutron][ops] VLAN Provider Network
by DHilsbos＠performair.com 07 Aug '21

07 Aug '21

All; We're using OpenStack Victoria, with OVS networking (no OVN). I'm having some problems with a VLAN provider network that I added to my OpenStack. I have other VLAN provider networks, that I based this one off of. Instances are getting the tap interfaces, but these interfaces are not getting IP addresses, and when a static IP is given, they can't ping either the DHCP address or the gateway address. I have checked the switch configuration, to verify the VLAN is bound appropriately. I rebooted the whole cluster to ensure the configuration change applied. Here's a snip our plugin.ini [ml2_type_vlan] network_vlan_ranges = provider_core:55:55,provider_core:64:64,... 64 works, 55, doesn't. I'm not seeing anything concerning in /var/log/openvswitch/ovs-vswitchd.log I'm sure it's something dumb, but I'm not seeing it. Any suggestions for what else to look at? Thank you, Dominic L.
