[venus][ptg]Venus vPTG Summary April 2021
by Liye Pang(逄立业) 27 Apr '21

27 Apr '21

Hi all, Thanks for all your participation! We've conducted the first meeting of venus last week and it is successful. Here's the summary of the topics we have discussed: *Progress in the past six months: - Develop devstack-based deployment for venus - Add log retrieval of modules such as vitrage - Develop the configuration, based on which you can retrieve the chain log of the call *Next step: - Develop alarm task code to set threshold for the number of error logs of different modules at different times, and provides alarm services and notification services - The configuration, analysis and alarm of Venus will be integrated into horizon in the form of plugin. - Develop a deployment method based on kolla-ansible - (discuss)Summarize the log specifications of some typical scenarios and develop them to venus - Evaluate whether to collect event data (considering usage, pressure, etc.We will continue to discuss with the telemetry project team) *Promblem: - Many projects's log records are not standardized, so they can only support full-text retrieval, not multi-dimensional analysis Full discussion (PTG etherpad): [1] https://etherpad.opendev.org/p/venus-xena-ptg Introduction of venus: [2] https://youtu.be/mE2MoEx3awM

How to delete such entities? Best regards, Adam Tomas

[Multi-arch SIG][sig][PTG] PTG Summary. Next meeting: May, 11.
by Rico Lin 27 Apr '21

27 Apr '21

Dear all Before we starts, just like to notify that we're not running meeting this week, but will run meeting at May, 11. So please join and provide topics if you got any: https://etherpad.opendev.org/p/Multi-Arch-agenda As we just have our PTG meeting last week, and I thank everyone who joins our PTG session. Here are some summaries from PTG: - Success to run full tempest tests on Arm64 env. What's next? - ML: http://lists.openstack.org/pipermail/openstack-discuss/2021-April/021600.ht… - Job patch: https://review.opendev.org/c/openstack/devstack/+/708317 - Job status: https://zuul.openstack.org/builds?job_name=devstack-platform-arm64+ - actions: - propose to add swift arm64 UT job: Swift is one of services directly touch file system or basic storage services. - pushing forward for integrating Ceph with current CI job to test more similar to user's environment - tunning volume backup/restore on the current job: - we might try to use POSIX as volume backup backend to testing performance issue. - ricolin and kevinz will take action to run tests locally for debugging - Also will try to switch to OSUOSL environment to check what kind of result we will face. - propose a periodic task for current CI job (once landed): as current job performance is not suitable for gating every patch set, I believe it will make sense to at least have a periodic job running. After performance issue is fixed, we can consider adding gating job or post-merge job. - We should also consider having multi-node job to test cross node. - SIG report (https://www.openstack.org/multi-arch-sig-report) - As general agreement that we definitely will generate report out to keep update the community with works related to multi-arch supports. Also hope to get use cases for share around. - We found some error in SIG report, but they are fixed now. - SIG video meeting - We discuss about the chances to run a video meeting. Once we have more material collected or topics ready. - Check libvirt 7 and cpu stuff - as libvirt 7 released this year, we should check if behavior changes: - There was code added for CPU features on migration - Need to check does 'cpu_mode' different than host-passthrough work now Please reference our PTG etherpad for more detailed discussion: https://etherpad.opendev.org/p/xena-ptg-multi-arch-sig *Rico Lin* OIF Board director, OpenStack TC, Multi-arch SIG chair, Heat PTL, Senior Software Engineer@EasyStack

[neutron]Really need some help in network aspect
by Rey 27 Apr '21

27 Apr '21

Hello, I'm not sure this is the right place, but I want to try whether if can I get any useful help. I stuck in some network problem for couple of days, and the problem I listed in https://github.com/projectcalico/calico/issues/4563 In short, the environment is kubernetes over openstack vm, and calico is kubernetes network componenet. However, the container to container network is very very slowly than host to host. So, I confused in questions: 1. Does kernel support double virturalization network? Like container network in vm 2. Is there any way to dig more? Sincerely, Yuan

[cyborg][ptg]Cyborg vPTG Summary April 2021
by Wang, Xin-ran 27 Apr '21

27 Apr '21

Hi all, Please ignore my previous message, it is sent to wrong person. Sorry about this. Thanks for all your participation! We've conducted a successful meeting last week. Here is the aggregated summary from Cyborg vPTG discussion. Please check it out and feel free to feedback any concerns you might have. We did a retrospective of Wallaby release, including: * We supports more operations supported for a VM with accelerator attached. * We introduced new drivers for Intel x710 NIC and Inspur's NVMe SSD Card. * We implemented a new configuration file allowing more flexible device configuration. Topic discussion: Here's some major discussion and conclusion of Cyborg vPTG. For more details, please refer to the etherpad[1]. * More nova operation supporting: - We prioritized the tasks: 1. suspend/resume. 2. cold migration. 3. live migration. * vGPU support: - We reached an internal agreement on whole workflow which can be apply as a generic framework for mdev device. * API enhancement: Some of the following items requires a new micro-version. - Add refresh policy check for all APIs. - Add device profile update API. - Add ARQ query by multiple instances API. - Add disable/enable device API, this one requires a spec first. - Enhance device profile show API with more information. * Cleanup issue: - This issue comes from the case where one compute node shutdown accidently, and the accelerator records in placement and cyborg DB remains as the orphaned resources. We agreed to implement a mechanism to clean up the orphaned resources, this one also need a spec. [1] https://etherpad.opendev.org/p/cyborg-xena-ptg Thanks, Xin-Ran Wang

[sdk]: compute service create_server method, how to create multiple servers
by dmeng 27 Apr '21

27 Apr '21

Hello there, Hope this email finds you well. We are currently using the openstacksdk for developing our product, and have a question about the openstacksdk compute service create_server() method. We are wondering if the "max_count" and "min_count" are supported by openstackskd for creating multiple servers at once. I tried both the max_count and the min_count, and they both only create one server for me, but I'd like to create multiple servers at once. The code I'm using is like the following: conn = connection.Connection( session=sess, region_name=None, compute_api_version='2') nova = conn.compute nova.create_server( name='sdk-test-create', image_id=image_id, flavor_id=flavor_id, key_name=my_key_name, networks=[{"uuid": network_id}], security_groups=[{'name':security_group_name}], min_count=3, ) The above code will create one server "sdk-test-create", but I'm assuming it should create three. Wondering did I miss anything, or if we have any other option to archive this? Thanks for your help and have a great day! Catherine
