[neutron] oslo.messaging and port notifications broadcast
by Thomas Goirand 09 Oct '25

09 Oct '25

Hi, Is it possible, with oslo.messaging, to have 3 daemons to get the Neutron port.{create,update,delete}.end notification events? I tried hard, but no mater how I do it, only one of my 3 daemons get the message. I'm about to add forwarding feature to the other 2 when one receives an event. Is there a better way? Cheers, Thomas Goirand (zigo)

by Andy Zhou 02 Oct '25

02 Oct '25

Hello Everyone, Any advice about configure of Openstack or OVN/OVS, to implement a centralized gateway of all the flows of VMs for flow audit? Since the default type is distributed mode for the East-West flow, I want to know if we can change to a centralized one? Thank you! Best regards, Andy Zhou

Using slave_connection in keystone for a read-only local database node
by Tyler Wilson 01 Oct '25

01 Oct '25

Hello All, I'm trying to get keystone to respect my slave_connection configuration to use a local database node in my galera cluster. I have this set currently; connection = mysql+pymysql://keystone:$PASSWORD@$DB_PRIMARY_WRITE_IP/keystone slave_connection = mysql+pymysql://keystone:$PASSWORD@$DB_LOCAL_READ_IP/keystone However whenever I have this configured I still am getting queries sent to the $DB_PRIMARY_WRITE_IP for even simple things like 'openstack user list'. Is there some other configuration I need to set for this to go to the read DB node? I have query logging enabled on the mariadb side to confirm where the requests are going. For troubleshooting I changed them both to the local DB node IP, and it can indeed process the sql requests fine. Operating System: Ubuntu 24.04 Package Version: 2:25.0.0-0ubuntu1 Thanks for any assistance!

Debian packages for Flamingo are available and validated
by Thomas Goirand 30 Sep '25

30 Sep '25

Hi, I am finished packaging Flamingo, at least for all artifacts that were released already. I was able to run tempest on it, and all went well. I uploaded all to Debian Unstable already minor a few packages (like Ironic, that is having issues coping with pysnmp 7, and mistral that is stuck on one of its unit tests: I'll investigate both soon). Packages are available through the usual channel. To get the osbpo.debian.net backport repository for Trixie, do: apt-get install extrepo extrep enable openstack_flamingo apt-get update Note that osbpo is now updated automatically on all git push based on event, rather than a cron job, so it's kind of instant now. So there's no reason to use the http://<debian-suite>-<openstack-release.debian.net repositories anymore (these are now only useful for me, internally, to build backport packages with Jenkins). Also, the deb-status page is also event driven, and updated each time a new package is updated. Please see: https://osbpo.debian.net/deb-status/ In there, you will see that I also took the time to update all past OpenStack release to the latest point release for all deliverables. Please report bugs through the usual channel: https://www.debian.org/Bugs/Reporting I'll package final versions as they come, though changes are expected to be minimal (if any change at all), as for every OpenStack release. Cheers, Thomas Goirand (zigo)

[openstack] about libvirt exporter
by Nguyễn Hữu Khôi 30 Sep '25

30 Sep '25

Hello. I see that this exporter looks like it collects a lot of information such as projectname, username or flavor of metrics but it looks not popular. It could help us build a very useful dashboard. https://github.com/zhangjianweibj/prometheus-libvirt-exporter I just want to understand some thoughts. Nguyen Huu Khoi

how to spare resource for evacuation
by Jiatong Shen 30 Sep '25

30 Sep '25

Hello experts, I would like to ask if there is a way to reserve some resources (CPU and Memory) in advance and later use them in case one compute node crashes. For example, vSphere implemetens Cluster Resources Percentage Admission Control [1] and could reserve resources beforehand. Thank you very much for the help. -- Best Regards, Jiatong Shen [1] https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/7-0/vsphere-…
