[Kolla Ansible] Error in "heat" stage during deployment - Followed Quick Start Guide (ubuntu 18.04.5, virtualbox)

Hi everyone, I am new to openstack and just followed the "Quick Start" guide for kolla-ansible [https://docs.openstack.org/kolla-ansible/ussuri/user/quickstart.html] on ussuri release, but now having some problems during deployment. I used virtualbox to create a new vm with ubuntu 18.04.5 [https://releases.ubuntu.com/18.04/ubuntu-18.04.5-live-server-amd64.iso.torr…] and attached one interface (enp0s3, 10.0.2.15) with Nat-Network and the second interface as for the neutron interface (enp0s8, no ip) an internal network and named it "neutron". Then I followed the guide to create a new virtual python environment (logged in over ssh using "user" user). -- sudo apt-get update sudo apt-get install python3-dev libffi-dev gcc libssl-dev sudo apt-get install python3-venv python3 -m venv $(pwd) source $(pwd)/bin/activate pip install -U pip pip install 'ansible<2.10' -- Everything seems to work as mentioned with no problems so far. (Beside the missing "python-venv" package in the docs) -- pip install kolla-ansible sudo mkdir -p /etc/kolla sudo chown $USER:$USER /etc/kolla cp -r $(pwd)/share/kolla-ansible/etc_examples/kolla/* /etc/kolla cp $(pwd)/share/kolla-ansible/ansible/inventory/* . mkdir /etc/ansible sudo nano /etc/ansible/ansible.cfg ### content from /etc/ansible/ansible.cfg [defaults] host_key_checking=False pipelining=True forks=100 ### -- I then modified the "multinode" file to only deploy on localhost (replaced all control01, etc. with localhost) as I first wanted to try openstack on one node. The ping worked, changed the globals.yml file according to the documentation, then bootstrap and the prechecks worked so far with no issue. -- ansible -i multinode all -m ping kolla-genpwd sudo nano /etc/kolla/globals.yml ### additional content of /etc/kolla/globals.yml kolla_base_distro: "ubuntu" kolla_install_type: "source" network_interface: "enp0s3" neutron_external_interface: "enp0s8" kolla_internal_vip_address: "10.0.2.10" ### kolla-ansible -i ./multinode bootstrap-servers kolla-ansible -i ./multinode prechecks -- But on the deploy stage I am stuck right now: -- kolla-ansible -i ./multinode deploy -- The mentioned error is telling me, that the keystone service is not available. I attached the error log file, because the error is longer. As a side node, now when I try to login using tty, the vm is nearly frozen and only prompts very, very slowly (about 10 minutes for prompt). ssh in putty is also frozen and the connection broke after about 30 minutes. Does anyone know what is wrong or has some hints/insight on how to correctly deploy openstack using kolla-ansible? Best Regards, Lukas Lüdke

[TC] Looking for a volunteer to help with community goal selection
by Nate Johnston 05 Sep '20

05 Sep '20

TC members, Since I have not been able to get in contact with Graham, I would like to see if there is anyone who would like to work with me for the selection of community goals for the W series. The commitment would be to identify a few good candidates that have well formulated goal proposals and champions, which usually involves a meeting followed by some reaching out and logistical work. I am hoping to increase the pool of those familiar with the goal selection process, so this is a great place to jump in if you have not done this before. Also, if Graham does have time then we can make sure to include him as well. Two is good but three is better! Please let me know if you are interested. Thanks! Nate

Mentoring Boston University Students
by Kendall Nelson 05 Sep '20

05 Sep '20

Hello! As you may or may not know, the last two years various community members have mentored students from North Dakota State University for a semester to work on projects in OpenStack. Recently, I learned of a similar program at Boston University and they are still looking for mentors interested for the upcoming semester. Essentially you would have 5 to 7 students for 13 weeks to mentor and work on some feature or effort in your project. The time to apply is running out however as the deadline is Sept 3rd. If you are interested, please let me know ASAP! I am happy to help get the students up to speed with the community and getting their workspaces set up, but the actual work they would do is more up to you :) -Kendall (diablo_rojo)

[oslo][ffe] request for oslo
by Herve Beraud 05 Sep '20

Hey Oslofolk, I request an FFE for these oslo.messaging changes [1]. The goal of these changes is to run rabbitmq heartbeat in python thread by default. Also these changes deprecating this option to prepare future removal and force to always run heartbeat in a python thread whatever the context. Land these changes during the victoria cycle can help us to prime the option removal during the next cycle.

[all][TC] OpenStack Client (OSC) vs python-*clients
by Belmiro Moreira 04 Sep '20

04 Sep '20

Hi, during the last PTG the TC discussed the problem of supporting different clients (OpenStack Client - OSC vs python-*clients) [1]. Currently, we don't have feature parity between the OSC and the python-*clients. Different OpenStack projects invest in different clients. This can be a huge problem for users/ops. Depending on the projects deployed in their infrastructures, they need to use different clients for different tasks. It's confusing because of the partial implementation in the OSC. There was also the proposal to enforce new functionality only in the SDK (and optionally the OSC) and not the project’s specific clients to stop increasing the disparity between the two. We would like to understand first the problems and missing pieces that projects are facing to move into OSC and help to overcome them. Let us know. Belmiro, on behalf of the TC [1] http://lists.openstack.org/pipermail/openstack-discuss/2020-June/015418.html

[nova] Session Recording for Feedback
by Apsey, Christopher 04 Sep '20

04 Sep '20

Nova supports using the websockify -record functionality to capture frames sent over arbitrary console sessions. Currently, the record = path/to/file option in nova.conf saves these sessions on nova-(spice|vnc)proxy endpoints at the specified path in the format of /path/to/file.(session number). These session numbers appear to be incrementally created starting from 1 and don't really have an association with their respective instance from what I can tell. It would be useful to have these files saved using the instance UUID instead. Ignoring that minor problem, playing back these files is a challenge. I've tried using noVNCs vnc_playback.html function from both the master branch and stable/v0.6 with no luck - it looks like the libraries and the utilities haven't been maintained at the same cadence and there are missing functions that the player is expecting. My goal here is to be able to capture the activities of students as they progress through various exercises and then have instructors be able to go over their work with them after the fact if they have questions. Has anyone been able to do this (or something like this) successfully, or are we just better off trying to do this in-band per instance? Chris Apsey GEORGIA CYBER CENTER
