[ironic]About the OS supported by Diskimage-builder
by Junya Noguchi (Fujitsu) 22 Jan '25

22 Jan '25

To whom it may concern. My name is Junya Noguchi. I have some questions about the supported OS for Diskimage-builder operation. Please respond. References https://docs.openstack.org/ironic-python-agent-builder/latest/admin/dib.html Does it mean that the OS that says "work but receive only limited testing and support" works but is not supported? References https://docs.openstack.org/diskimage-builder/latest/ This document describes RHEL and other operating systems that are not supported in the previous question. Are these operating systems supported? Also, are there any plans to support more operating systems in the future? Best regards, Junya Noguchi

[glance][ops] proposal to remove the glance-scrubber
by Brian Rosmaita 20 Jan '25

20 Jan '25

Hello Glance users, The Glance project team wants to determine whether anyone is using the glance-scrubber utility [0]. If not, we are thinking of deprecating it this cycle to be removed in the appropriate future cycle. If you have not previously heard of the glance-scrubber, that's most likely because it's only useful for particular deployment configurations of which yours is not one. See the doc [0] for details if you are curious. Our suspicion is that the glance-scrubber may have outlived its usefulness for modern OpenStack configurations. (The last time I remember it being discussed at a PTG was during the snowstorm in Dublin, which I believe was the Rocky development cycle). On the other hand, the team also has some ideas for improving the scrubber, but there's no point doing that if it's not actually being used in the first place. So if removal of the glance-scrubber would negatively affect you, please respond to this email so we can get some data points. Thanks!

[cinder][kubernetes] pvc stuck in reserved state
by Eugen Block 10 Jan '25

10 Jan '25

Hi, we have a couple of k8s clusters in our openstack environment (Victoria) and are facing some problems when pods get moved to different worker nodes. The PVCs get stuck in "reserved" state, and they only get attached after resetting the volumes to "available" state. First I thought it was due to the missing multiattach volume type which seems to work fine in our customer's cluster. I also found the "duplicate connector" error messages in the nova-compute.log: > Unable to update attachment.(Invalid volume: duplicate connectors > detected on volume But after adding the multiattach volume type and retyping the affected volumes, the PVCs still get stuck in "reserved" state while I don't see any error messages on the hypervisors anymore. So it seems that something has changed/improved, but now I don't have a trace where to look next. Could this be a cinder-csi driver issue or something? Our cinder backend is ceph (Pacific). Not sure which information could help so please ask for anything I can provide. Any pointers are highly appreciated! Thanks! Eugen

Kolla Ansible on Ubuntu 20.04 - cloud-init & other network issues
by Tobias McNulty 10 Oct '24

10 Oct '24

Hi, I'm attempting to use Kolla Ansible 14.6.0 to deploy OpenStack Yoga on a small 3-node Ubuntu 20.04 cluster. The nodes have 128 GB RAM each, dual Xeon processors, and dual 10G Intel NICs. The NICs are connected to access ports on a 10G switch with separate VLANs for the local and external networks. All the playbooks run cleanly, but cloud-init is failing in the Ubuntu 20.04 and 22.04 VMs I attempt to boot. The VM images are unmodified from https://cloud-images.ubuntu.com/, and cloud-init works fine if I mount a second volume with user-data. The error is a timeout attempting to reach 169.254.169.254. This occurs both when booting a VM in an internal routed network and directly in an external network. I tried various neutron plugin agents (ovn, linuxbridge, and openvswitch both with and without firewall_driver = openvswitch <https://docs.openstack.org/kolla-ansible/latest/reference/networking/neutro…>) first with a clean install of the entire OS each time, all with the same result. Running tcpdump looking for 169.254.169.254 shows nothing. As a possible clue, the virtual NICs are unable to pass any traffic (e.g., to reach an external DHCP server) unless I completely disable port security on the interface (even if the associated security group is wide open). But disabling port security does not fix cloud-init (not to mention I don't really want to disable port security). Are there any additional requirements related to deploying OpenStack with Kolla on Ubuntu 20.04? This is a fairly vanilla configuration using the multinode inventory as a starting point. I tried to follow the Quick Start <https://docs.openstack.org/kolla-ansible/yoga/user/quickstart.html> as closely as possible; the only material difference I see is that I'm using the same 3 nodes for control + compute. I am using MAAS so it's easy to get a clean OS install on all three nodes ahead of each attempt. I plan to try again with the standard (non-HWE) kernel just in case, but otherwise I am running out of ideas. In case of any additional clues, here are my globals.yml and inventory file, along with the playbook I'm using to configure the network, images, VMs, etc., after bootstrapping the cluster: https://gist.github.com/tobiasmcnulty/7dbbdbc67abc08cbb013bf5983852ed6 Thank you in advance for any advice! Cheers, Tobias

Live migration fails
by Szabo, Istvan (Agoda) 07 Aug '24

07 Aug '24

Hi, I have couple of compute nodes where the live migration fails with existing vms.

However I have many existing vms where it fails with a servername not found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 ERROR nova.conductor.tasks.migrate [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Unable to find record for source node servername on servername: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Failed to compute_task_migrate_server: Compute host servername could not be found.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Setting instance to ACTIVE state.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.672 227612 ERROR oslo_messaging.rpc.server [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Exception during message handling: ComputeHostNotFound: Compute host am-osfecn-4025 Tried with this command: nova live-migration --block-migrate id.

[Tempest] [Blazar] Connection Refused Error 111 on Blazar tempest plugin
by Tran, Kenny 28 May '24

28 May '24

First time asking a question on the mailing list, I am trying to set up tempest against a quick start yoga (kolla-ansible) deployment with Keystone, Zun, Heat, Blazar, and Nova (1 controller, 1 compute). Default tempest tests are behaving as expected but when I try to run the blazar plugin tests they fail with Errno 111 Connection Refused. I ran a tcpdump on the tempest server side and saw no issues. Tcpdump on controller showed a reset when trying to connect to keystone. Is this an issue with blazar not being able to authenticate against the openstack deployment? The default tempest tests succeed so I don't think my admin_password admin_username etc. are incorrect. Kenny Tran Iowa State University Student Computer Engineer 515-441-5237 | trantk(a)iastate.edu

[ptl][tc] OpenStack packages PyPi additional external maintainers audit & cleanup
by Ghanshyam Mann 17 May '24

17 May '24

Hi PTLs, As you might know or have seen for your project package on PyPi, OpenStack deliverables on PyPi have additional maintainers, For example, https://pypi.org/project/murano/, https://pypi.org/project/glance/ We should keep only 'openstackci' as a maintainer in PyPi so that releases of OpenStack deliverables can be managed in a single place. Otherwise, we might face the two sets of maintainers' places and packages might get released in PyPi by additional maintainers without the OpenStack project team knowing about it. One such case is in Horizon repo 'xstatic-font-awesome' where a new maintainer is added by an existing additional maintainer and this package was released without the Horizon team knowing about the changes and release. - https://github.com/openstack/xstatic-font-awesome/pull/2 To avoid the 'xstatic-font-awesome' case for other packages, TC discussed it in their weekly meetings[1] and agreed to audit all the OpenStack packages and then clean up the additional maintainers in PyPi (keep only 'openstackci' as maintainers). To help in this task, TC requests project PTL to perform the audit for their project's repo and add comments in the below etherpad. - https://etherpad.opendev.org/p/openstack-pypi-maintainers-cleanup Thanks to knikolla to automate the listing of the OpenStack packages with additional maintainers in PyPi which you can find the result in output.txt at the bottom of this link. I have added the project list of who needs to check their repo in etherpad. - https://gist.github.com/knikolla/7303a65a5ddaa2be553fc6e54619a7a1 Please complete the audit for your project before March 15 so that TC can discuss the next step in vPTG.

neutron's OVS based VXLAN seems to be unable to access the network
by 2292613444＠qq.com 07 May '24

07 May '24

I found that the cloud host I created cannot connect to the network. The network type is VXLAN, and it cannot even access cloud init I used this installation document (partially in Chinese) and it was normal around 2022, but it cannot be used after updating the software source recently. The use of VXLAN in cloud hosts has the following faults (1) Unable to access network resources other than ICMP (ping), and even curl http://169.254.169.254 (This also leads to the inability to use cloud init) (2) Sometimes unable to ping 169.254.169.254 for unknown reasons. (3)Any service other than ICMP service cannot be accessed, All firewalls and security groups are allowed or closed. My network situation is as follows Internal (vxlan) 10.0.0.0/24 Gateway 10.0.0.1 Router gateway 10.0.0.1 → 192.168.10.121 External (flat) 192.168.10.11.0/24 Gateway 192.168.10.1.1 If any other information is needed, I can provide it and hope to fix this error. system version:ubuntu 22.04 last version (online ) openstack Y version I used a command in the openstack routing host to check The specific details are as follows：：（10.0.0.129 is cloud host,vxlan is port qr-4528fcca-21） ###start root@controller:~# ip netns qdhcp-2aa854ba-7fa6-43e4-989e-e97dafd777ee (id: 1) qdhcp-c7d9811d-1fcc-4aee-8f01-6f556fb56044 (id: 2) qrouter-48610214-6030-4e7e-8fe8-c60241e7c89c (id: 0) root@controller:~# ip netns exec qrouter-48610214-6030-4e7e-8fe8-c60241e7c89c bash root@controller:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 13: qr-4528fcca-21: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether fa:16:3e:41:c8:47 brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/24 brd 10.0.0.255 scope global qr-4528fcca-21 valid_lft forever preferred_lft forever inet6 fe80::f816:3eff:fe41:c847/64 scope link valid_lft forever preferred_lft forever 14: qg-622550f9-80: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether fa:16:3e:31:eb:c2 brd ff:ff:ff:ff:ff:ff inet 192.168.101.121/24 brd 192.168.101.255 scope global qg-622550f9-80 valid_lft forever preferred_lft forever inet 192.168.101.177/32 brd 192.168.101.177 scope global qg-622550f9-80 valid_lft forever preferred_lft forever inet6 fe80::f816:3eff:fe31:ebc2/64 scope link valid_lft forever preferred_lft forever root@controller:~# tcpdump -i qr-4528fcca-21 -vvvvv tcpdump: listening on qr-4528fcca-21, link-type EN10MB (Ethernet), snapshot length 262144 bytes 17:36:02.295718 IP6 (hlim 1, next-header Options (0) payload length: 36) :: > ff02::16: HBH (rtalert: 0x0000) (padn) [icmp6 sum ok] ICMP6, multicast listener report v2, 1 group record(s) [gaddr ff02::1:ff0f:28ea to_ex { }] 17:36:02.371746 IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: [udp sum ok] BOOTP/DHCP, Request from fa:16:3e:0f:28:ea (oui Unknown), length 300, xid 0xe07c1d6a, Flags [none] (0x0000) Client-Ethernet-Address fa:16:3e:0f:28:ea (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Discover Parameter-Request (55), length 13: Subnet-Mask (1), BR (28), Time-Zone (2), Classless-Static-Route (121) Domain-Name (15), Domain-Name-Server (6), Hostname (12), YD (40) YS (41), NTP (42), MTU (26), Unknown (119) Default-Gateway (3) END (255), length 0 PAD (0), length 0, occurs 41 17:36:02.373214 IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: [udp sum ok] BOOTP/DHCP, Request from fa:16:3e:0f:28:ea (oui Unknown), length 300, xid 0xe07c1d6a, Flags [none] (0x0000) Client-Ethernet-Address fa:16:3e:0f:28:ea (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Request Server-ID (54), length 4: 10.0.0.2 Requested-IP (50), length 4: 10.0.0.129 Parameter-Request (55), length 13: Subnet-Mask (1), BR (28), Time-Zone (2), Classless-Static-Route (121) Domain-Name (15), Domain-Name-Server (6), Hostname (12), YD (40) YS (41), NTP (42), MTU (26), Unknown (119) Default-Gateway (3) END (255), length 0 PAD (0), length 0, occurs 29 17:36:02.402630 ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 10.0.0.1 tell 10.0.0.129, length 28 17:36:02.402639 ARP, Ethernet (len 6), IPv4 (len 4), Reply 10.0.0.1 is-at fa:16:3e:41:c8:47 (oui Unknown), length 28 17:36:02.403415 IP (tos 0x0, ttl 64, id 47481, offset 0, flags [DF], proto UDP (17), length 72) 10.0.0.129.46568 > 223.5.5.5.domain: [udp sum ok] 57238+ A? does-not-exist.example.com.

[all][oslo][neutron][glance][ironic] Deprecating eventlet based WSGI server
by Takashi Kajinami 07 May '24

07 May '24

Hello, As you know there has been a long discussion about eventlet usage in OpenStack, and after seeing multiple problems caused by the library and no long term plan in the project, and we are moving toward doping the dependency on eventlet. https://review.opendev.org/c/openstack/governance/+/916546 One of the core implementation which heavily depends on eventlet is WSGI server. Multiple projects have been providing the -api console scripts (eg nova-api) based on the oslo.service's WSGI server implementation which depends on eventlet. On the other hand, nowadays we have multiple methods to launch api services, such as httpd+mod_wsgi, uwsgi and gunicorn. And a few projects in OpenStack don't provide the -api console script (eg. aodh, barbican and placement) but suggest using these external frameworks to run their api WSGI application. I know that multiple deployment tools (for example TripleO in the past) and some distros (Debian) already started using the external framework for consistency, better concurrency and so on. Given the situation, I wonder if we can consider deprecating the eventlet WSGI server in oslo.service in 2024.2/2025.1 and eventually remove all -api script in 2025.2. This was discussed during the previous nova PTG sessions and I think this makes complete sense as a global direction given the variety of alternative approaches currently available. I'm tagging neutron(*1) and glance(*2) because IIRC these had(or even have) some problems with running API in wsgi mode, and also ironic because I've seen some works coming from it, iiuc. Please let me know if you have any concern applying this approach to these (or the other) projects. Thank you, Takashi Kajinami (*1) For neutron, there are a few issues being fixed now https://bugs.launchpad.net/neutron/+bug/2062009 but ml2-ovn may need additional fixes. https://bugs.launchpad.net/neutron/+bug/1912359 (*2) As far as I know the issue with glance was already fixed some time ago[1]. https://bugs.launchpad.net/glance/+bug/1888713 -- Takashi Kajinami irc: tkajinam github: https://github.com/kajinamit launchpad: https://launchpad.net/~kajinamit

[all][packaging][release][qa] pep-517 and pip 23
by smooney＠redhat.com 06 May '24

06 May '24

hi folks, TL;DR ----- this is a long email so the tl;dr is we should add pyproject.toml ``` [build-system] requires = ["pbr>=5.7.0", "setuptools>=36.6.0", "wheel"] build-backend = "pbr.build" ``` to all openstack projects to supprot pip 23.1+ Long version ------------ As some of you may know the ptg happend last week an done of hte topic raised there was a know limitation in devstack where GLOBAL_VENV=True does not work on centos/fedora derived distros. while i generally dont use centos/fedora derived distros for my daily work i have been using devstack for over 10 years at this point so when im told it broken i ocationlly will go fix it. In this case the issue is not with devstack (it often isnt) and is actully in our collective reliance on a deprecated functionality and how we package openstack today. Back story, for better or worse when openstack was created the landscape of python packaging was significantly different then it is today. To help corodinate our dependcies the openstack comunity went all in on requirements.txt and developed upper-constraits to manage our requirements and developed PBR (python build Reasonableness). both of those approches have served us well and likely will continue to do so for some time. Since then pyproject.toml has started to gain popularity and pep-517 (A build-system independent format for source trees) has been adotpted but so far openstack as a comunity has not embraced those changes. (although pbr already supprot pep-517 :) ). Until now this has not been a problem however with recent release of pip things are now breaking. Problem Context: - openstack does not provide pyporject.toml files - openstack project configure setuptools to use pbr via setup.py - setuptools support generating scripts form entry points(console_scripts) which we use for project binaries( nova- compute, neutron-server, ...) - openstack api services use a pbr extension know as wsgi_scripts which adds a similar functionality for generating wsgi application mains file - devstack due to coming changes in distro to block "sudo pip install" now installs openstack in a single by default on debian distros. on centos/fedora distros it currently almost functional (but not). - devstack installs in editable mode because that is how most developers use devstack for developemnt What changed: - pip 20.2 deprecated support for falling back to calling setup.py when pyproject.toml is not present - https://pip.pypa.io/en/stable/news/#v20-2 - https://github.com/pypa/pip/issues/8368 - at this point when pyproject.yaml is not called pip calls setup.py install [-e] <path to repo or package name> - setup.py invokes pbr to generate wsgi_scripts and other files - in pip 23.1 the fallback was removed https://pip.pypa.io/en/stable/news/#v23-1 - pip now builds a temp local wheel instead of calling setup.py install when pyproject.toml is not found - in editable mode (-e) the default way the wheel is built does not invoke pbr properly to generate the wsgi files - as a result the wsgi files are not installed to the venv bin dir and this causes devstack to fail to start keystone (or any other wsgi api) The fix, there are a few ways to approch this: - clamp pip (https://review.opendev.org/c/openstack/devstack/+/898845) this is a terible idea and it breaks debian - clamping pip below 23.1 works on centos for now however OVS on debian already requires pep 517 for installing - as such when that version of ovs (or other projects start enforcing that) hits centos it will break - add a minimal pyproject.toml to all openstack project - example for keystone https://review.opendev.org/c/openstack/keystone/+/899519 - this example jsut adds the minium pyproject.toml to enable pbr to be used as the build system - it does not remove supprot for setup.py but it will not be used by default going forward whit new version of pip - all config is still in setup.cfg - add pyproject.toml support but remove setup.py support https://review.opendev.org/c/opendev/bindep/+/816741 - this goes one step futrue and actuly nulls out setup.py - we could take this approach if we want to but its not required. The reason for this email is to get agreement on how to support pip 23.1+ My proposal would be to add pyproject.toml with the minimal config required to enable pip 23.2 but not drop the setup.py support in this cycle. i would suggest that we can deprecate installing via setup.py in caracal if that is desirable but not make that change until the next slurp to give time to projects and packages to catch up. if there are no objections to that i would like to ask what is the preferd way to create and submit the patches for the minimal pyproject.toml ``` [build-system] requires = ["pbr>=5.7.0", "setuptools>=36.6.0", "wheel"] build-backend = "pbr.build" ``` i can propose patches to the main project deployed by devstack by default. i.e. nova/neutron ectra but it might be better if someone form the core teams of each project could take on that task and chasing the reviews. if someone has a script to generate a patch for a set of repos that just add the above pyporject.toml then we can use that to keep a consistent topic/commit message across all patches. my proposal for testing this is two fold. in ci we can test the patches are functional by using a DNM patch to devstack to force enable the gloal venv on centos and depend on the set of patches, i will modify https://review.opendev.org/c/openstack/devstack/+/898845 to do that locally we can test that the patch is functional by doing the following substituting keystone for the relevant project. ``` git clone https://opendev.org/openstack/keystone cd keystone python3 -m venv .venv . .venv/bin/activate python3 -m pip install -U pip python3 -m pip install -e . ls .venv/bin/keystone* ``` the ls will not contain the wsgi script with the addition of the pyproject.toml it should. on debian sid i can reproduce the same issue the problem we are seeing on centos 9 now will start impacting other distos eventually so its good to fix this now. if i start proposing this to glance/nova/neutron/cinder/swift/horizon/placement (to get a default devstack working) can i get cores to review? can cores form each project nominate peopel to review or volenteer to do this work. i have created https://etherpad.opendev.org/p/pep-517-and-pip-23 to track this work i have some other work that i think we can do in parallel like addign pyporject.toml support to the pti requirements if we go this way but that i think we can discuss on a governacne patch to updated it. anyway this is a lot to digest so feedback is welcome. if someone else would like to drive this that is also welcome (i.e. tc/release team) regards sean.

[nova][cinder] Openstack with FC SAN storage with HA
by Satish Patel 06 May '24

06 May '24

Folks, I have a question, Does openstack support FC SAN storage? I have deployed openstack with ceph but first time got this requirement that a customer has SAN storage because they were using VMware but now move to openstack. How does openstack talk to FC SAN and what about VM migration etc? Do I need to mount the LUN disk on each computer and point nova to the LUN disk? Or I have to create some kind of shared file system on top of the LUN and expose that to nova/cinder. Can someone explain the entire workflow?
