by Eduardo Gonzalez 25 Jan '19

25 Jan '19

Reading the info in the COA site [0] says the following* "The OpenStack Foundation is winding down the administration of the COA exam".* Is there any reason for retiring the exam? I've tried to find a notice in the mailing list but not found anything at all. [0] https://www.openstack.org/coa/ Regards

Not getting full bandwidth VXLAN + DVR
by Yedhu Sastri 25 Jan '19

25 Jan '19

Hello, In our OpenStack environment(Newton) we are using 10G network in all our nodes. We are using OVS bridging with VXLAN tunneling and DVR. We also enabled Jumbo frames in NIC and also in physical switches. We also enabled VXLAN offloading in our NIC. irqbalance is running which suppose to distribute the network irqs to all cores of the CPU. But unfortunately we are only getting below 1G bandwidth when communicate with our VM's with floating IP's from compute hosts. We tested it using iperf and results are like Host to VM using floating IP - less than 1Gbits/sec VM to VM using internal IP - ~2.5Gbits/sec Any idea or solutions to solve this issue is much appreciated. -- With kind regards, Yedhu Sastri

[Keystone] How to retrieve secret key for a given access key id
by Pritha Srivastava 24 Jan '19

24 Jan '19

Hi All, I have a scenario where I need to retrieve the secret key of a given access key id (of EC2 credentials) from Keystone. I know that this can be done by sending a GET request to the following URL: v3/users/{user_id}/credentials/OS-EC2/access_key_id I don't have the user_id required for the above request, but I have the admin username and admin password, that was used to create the EC2 credentials. Is there a way to get the user_id, and then get the secret key from Keystone? Thanks, Pritha

[nova][dev] stein blueprint tracking status
by melanie witt 24 Jan '19

24 Jan '19

Hi all, I've updated our stein blueprint tracking status etherpad with all of our approved blueprints for the cycle and notes about their current status: https://etherpad.openstack.org/p/nova-stein-blueprint-status Feature freeze s-3 is fast approaching on March 7. Let's use this etherpad to help us focus our work and complete as much as we can in the next 6 weeks. At the top, I've collected status on our cycle themes. TL;DR is that some efforts have stalled and we probably need people to jump in and help. Some people are already helping, and that's awesome! Please use this etherpad as a review guide and a place to communicate notes about blueprint status and progress, anything that will help us all move forward on completing implementations and reviews. Communication will be key as we try to get things done by s-3. Use the etherpad, #openstack-nova on IRC, and the ML to ask questions, get unstuck, and give updates. Let me know if I've missed any blueprints and feel free to add notes about any items that need to be moved, etc. Cheers, -melanie

[magnum] Persistent Volume Claim with cinder backend
by Christian Zunker 24 Jan '19

24 Jan '19

Hi, we are running Magnum Rocky. I tried to create a persistent volume claim and got it working with provisioner: kubernetes.io/cinder But it failed with provisioner: openstack.org/standalone-cinder The docs state kubernetes.io/cinder is deprecated: https://kubernetes.io/docs/concepts/storage/storage-classes/#openstack-cind… Which one should be used in Rocky? This is our complete config for this case: apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: cinder annotations: storageclass.beta.kubernetes.io/is-default-class: "true" labels: kubernetes.io/cluster-service: "true" addonmanager.kubernetes.io/mode: EnsureExists provisioner: openstack.org/standalone-cinder parameters: type: volumes_hdd availability: cinderAZ_ceph --- kind: PersistentVolumeClaim apiVersion: v1 metadata: name: myclaim spec: accessModes: - ReadWriteOnce resources: requests: storage: 42Gi storageClassName: cinder regards Christian

[ptl][goals][python3] please update your team's status in the wiki
by Doug Hellmann 24 Jan '19

24 Jan '19

I noticed this morning that the last time the Python 3 status page [1] was updated in the wiki was August. I hope we've had changes to the level of support since then. Keeping that page up to date is part of fulfilling the goal this cycle. Please take a few minutes to review the content today and update it if necessary. Thanks!

[openstack-dev] [neutron]
by Farhad Sunavala 24 Jan '19

24 Jan '19

Hi, I am open to suggestions.We have a need to switch traffic from our project to other projects without first getting out on the internet, floating IPs, etc. The other projects will be sharing their networks with our project.As shown in figure below, the orange network belongs to our project (10.0.0.0/26) The green network (172.31.0.0/24) belongs to another project andhas an overlapping network with the red tenant (172.31.0.0/16) For now, the solution is to create VMs in our project and make sure none of the interfaceshaving overlapping CIDRs. Thus, there is a VM attached to the 'orange' and 'red' netsand another VM attached to the 'orange' and 'green' nets. Problem: Too much resources (VMs) will need to be created if we have 100 tenants with overlapping networks. Solution:Is there a way I can minimize VM resource in our project by not allocating a separate VMfor shared networks with overlapping CIDRs? thanks,

[tc][telemetry][horizon] ceilometer-dashboard repository creation
by Jakub Slíva 24 Jan '19

24 Jan '19

Hello, our company created a little plugin to Horizon and we would like to share it with the community in a bit more official way. So I created change request (https://review.openstack.org/#/c/619235/) in order to create official repository under project Telemetry. However, PTL recommended me to put this new repository under OpenStack without any project - i.e. make it unofficial. I have also discussed this with Horizon team during their meeting (http://eavesdrop.openstack.org/meetings/horizon/2019/horizon.2019-01-09-15.…) and now I am bit stuck because I do not know how to proceed next. Could you, please, advise me? All opinions are appreciated. Jakub Sliva Ultimum Technologies s.r.o. Na Poříčí 1047/26, 11000 Praha 1 Czech Republic http://ultimum.io
