How to create snapshot via python module?
by Saeed 08 Oct '24

08 Oct '24

Hello, this is my full code to create a snapshot from an instance. The code creates a new image with type snapshot, but after around 2 hours, its status is still in queue. But when I create another snapshot via the Openstack UI, it works fine. Would you please help me how can I create a snapshot? import openstack import datetime now = datetime.datetime.now() today = now.strftime('%Y_%m_%d_%H_%M_%S') openstack.enable_logging(debug=False) servers = [] images = [] openstack_connection = openstack.connect(cloud='region1') # clouds.yaml for server in openstack_connection.compute.servers(details=True, hostname='my_server'): servers.append(server.to_dict()) servers = servers[0] for image in openstack_connection.compute.images(details=True, id=servers['image']['id']): images.append(image.to_dict()) images = images[0] name = f'my_server_{today}' openstack_connection.image.create_image( name=name, disk_format='raw', container_format='bare', visibility='private', timeout=1, properties={ 'hw_disk_bus': 'scsi', 'hw_qemu_guest_agent': 'yes', 'hw_scsi_model': 'virtio-scsi', 'hw_watchdog_action': 'reset', 'base_image_ref': servers['image']['id'], 'owner_user_name': 'whmcs', 'owner_project_name': 'admin', 'boot_roles': 'admin,reader,member', 'os_admin_user': 'administrator', 'os_distro': 'windows', 'os_type': 'windows', 'owner_specified.openstack.object': images['metadata']['owner_specified.openstack.object'], 'clean_attempts': '1', 'hw_machine_type': 'pc', 'password_0': '', 'password_1': '', 'password_2': '', 'password_3': '', 'hw_cdrom_bus': 'ide', 'hw_input_bus': 'usb', 'hw_pointer_model': 'usbtablet', 'hw_video_model': 'virtio', 'hw_vif_model': 'virtio', 'instance_uuid': servers['id'], 'image_type': 'snapshot', } )

[neutron] OVS Agent constant bridges recreation
by Artsiom Antropau 08 Oct '24

08 Oct '24

Hi, Team! Pretty long time we’re experiencing some troubles with auto-restoration of ovs after some storms. We’re using neutron-wallaby and openvswitch 2.15. The problem is the next: After some storms we’re receiving situation, when ovs agent constantly recreating bridges and doing full syncs, which affects our network stability. All versions (incl. 2024.2), containing some parts of code that I want to highlight: 1. Non-empty `idl_monitor.bridges_added` triggers 2. `_do_reconfigure_physical_bridges`, then it triggers 3. `setup_physical_bridges(bridge_mappings)` then it contains 4. br.create() I’m seeing note in code «The bridge already exists, so create won't recreate it», BUT at the same time we’re receiving in logs: ``` Matched CREATE: BridgeCreateEvent(events=('create',), table='Bridge', conditions=None, old_conditions=None) to row=Bridge(name=br-tun ``` and ``` BridgeCreateEvent, bridge name: br-tun ``` Constantly – by hours and for all our bridges (we have four: br-tun, br-ex, br-int, br-rmi) while we will not restart ovs agent. So this event filling idl_monitor.bridges_added then ovs reacting on it by _do_reconfigure_physical_bridges, then it triggers br.create() and we’re receiving event once again – we’re in loop. Want to add that our datapath-id NOT changing between these runs – keeps same. Any ideas or ways how to fix this problem and never experience it next?

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-25)
by Goutham Pacha Ravi 08 Oct '24

08 Oct '24

Hello Stackers, This week, we begin our 26-week endeavor towards the next SLURP release, 2025.1 ("Epoxy") [1]. OpenStack Project Teams will meet virtually at the Project Teams Gathering (PTG) in two weeks, starting on 2024-10-21 [2]. The OpenStack TC plans to host cross project meetings during the following time slots: - 2024-10-21 (Monday): 1400 UTC - 1700 UTC - 2024-10-25 (Friday): 1500 UTC - 1700 UTC You'll find the proposed topics on the PTG Etherpad [3]; please add your IRC nickname if you'd like to attend or be notified when discussions begin. Last week, a few community leads presented at OpenInfra Live, recapping the 2024.2 release [4]. I encourage you to watch the presentation and follow the themes each team is pursuing in the "Epoxy" release cycle. I'm excited to share that the organizers of the upcoming OpenInfra Days North America (Oct 15-16) have made it a hybrid event. Please register if you plan to attend virtually [5]. === Weekly Meeting === The last weekly meeting of the OpenStack Technical Committee was held simultaneously on IRC [6] and video [7]. We discussed meeting times, and the current time (Tuesdays at 1800 UTC) was retained due to a lack of consensus on better alternatives. Sylvain Bauza (bauzas) volunteered to be an Election Official for the 2025.2 elections, which will be announced around February 2025. We also discussed "leaderless" projects for the 2025.1 release and appointed leaders for the OpenStack Mistral, OpenStack Watcher, and OpenStack Swift projects. Additionally, we created a TC tracker for the 2025.1 release cycle [8] to monitor the progress of community goals and other governance initiatives. The next OpenStack Technical Committee meeting is today (2024-10-08) at 1800 UTC on the #openstack-tc IRC channel on OFTC. You can find the agenda on the weekly meeting wiki page [9]. I hope you can join us! Below is a list of governance changes that have merged in the past week and those still pending community review. === Governance Proposals === ==== Merged ==== - Appoint Tim Burke as PTL for Swift | https://review.opendev.org/c/openstack/governance/+/928881 ==== Open for Review ==== - Mark kuryr-kubernetes and kuryr-tempest-plugin inactive | https://review.opendev.org/c/openstack/governance/+/929698 - Add Axel Vanzaghi as PTL for Mistral | https://review.opendev.org/c/openstack/governance/+/927962 - Propose the eventlet-removal community goal | https://review.opendev.org/c/openstack/governance/+/931254 === Upcoming Events === - 2024-10-08: OpenInfra Monthly Board Meeting: https://board.openinfra.dev/ - 2024-10-15: OpenInfra Days NA, Indianapolis: https://ittraining.iu.edu/explore-topics/titles/oid-iu/ - 2024-10-21: OpenInfra Project Teams Gathering: https://openinfra.dev/ptg/ Thank you for reading!

L2 gateway
by engineer2024 07 Oct '24

07 Oct '24

I am trying to understand the L2-GW concept in openstack neutron. I understand that its primary purpose is to bridge two l2 networks into one single network. We have tenant and provider networks in neutron. 1. Why would anyone want to bridge two l2 networks in the first place ? 2. Can these two l2 networks be, two unroutable tenant networks ? Please bear with my ignorance here. I am trying to grasp and learn these concepts. Any help in this regard is much appreciated... Thanks elinux

[neutron][nova][oslo][all] Common middleware to log requests
by Takashi Kajinami 07 Oct '24

07 Oct '24

Hello, (I'm adding tags from teams which may be directly involved with this discussion but also add all tag because this topic is actually a global topic) I recently spent some time to try neutron deployments with api run by httpd and rcp-server, and I noticed that I no longer see request details logged in neutron logs. It used to be logged by WSGI server implementation in oslo.service (which heavily depends on eventlet and being removed). Based on my past experience, the information is quite important when we have to debug any problems triggered by API request (API returned 500, Tried to create a resource but it failed, etc...). WSGI server (uwsgi or apache) may have their own request loggings but the problem with these is that these do not log context details (especially request id) so analyzing logs is still difficult. I initially created https://bugs.launchpad.net/neutron/+bug/2083760 to discuss this problem in neutron. However, when I looked at a few other repos, I noticed that current implementation is quite inconsistent across projects and now I think this needs to be discussed as a more global topic. IMO the current inconsistency makes debugging quite difficult and we need more consistent logging to help operators get more consistent and detailed information. 1. Some projects (eg. aodh, designate, octavia) does not log requests 2. Other projects (eg. cinder, glance, heat) log requests in their logic but does not log some items such as remote addr and response time. 3. nova[1] and placement[2] have own request_log middleware with more complete information (but one in nova does not have debug log dumped when api starts processing the request) I'm wondering if it makes sense to import the existing request_log middleware implementation from nova/placement and use it globally (and drop the existing logging with less incomplete information to avoid redundant logs). Thank you, Takashi [1] https://github.com/openstack/nova/blob/master/nova/api/openstack/requestlog… [2] https://github.com/openstack/placement/blob/master/placement/requestlog.py -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

[neutron] [ovs] OVS agent constant bridge recreate flow

Hi, Team! Pretty long time we’re experiencing some troubles with auto-restoration of ovs after some storms. We’re using neutron-wallaby and openvswitch 2.15. The problem is the next: After some storms we’re receiving situation, when ovs agent constantly recreating bridges and doing full syncs, which affects our network stability. All versions (incl. 2024.2), containing some parts of code that I want to highlight: 1. Non-empty `idl_monitor.bridges_added` triggers 2. `_do_reconfigure_physical_bridges`, then it triggers 3. `setup_physical_bridges(bridge_mappings)` then it contains 4. br.create() I’m seeing note in code «The bridge already exists, so create won't recreate it», BUT at the same time we’re receiving in logs: ``` Matched CREATE: BridgeCreateEvent(events=('create',), table='Bridge', conditions=None, old_conditions=None) to row=Bridge(name=br-tun ``` and ``` BridgeCreateEvent, bridge name: br-tun ``` Constantly – by hours and for all our bridges (we have four: br-tun, br-ex, br-int, br-rmi) while we will not restart ovs agent. So this event fills idl_monitor.bridges_added then ovs reacting on it by _do_reconfigure_physical_bridges, then it triggers br.create() and we’re receiving event once again – we’re in the loop. Want to add that our datapath-id NOT changing between these runs – keeps same. Additional debugging shows that bridges `_uuid` are not changing in tables, which means that rows were not added => but for some reason, we’re receiving an event about it. Any ideas or ways how to fix this problem and never experience it again?
