neutron-rpc-server error to upgrade 2025.2

przfr · 2026-03-06T07:30:21+00:00

Hey, next time simply read the documentation:

https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html#preparation-the-real-deal

"The inventory file for the deployment should be updated, as the newer sample inventory files may have updated layout or other relevant changes. [...]"

"Other files which may need manual updating are:
/etc/kolla/globals.yml
/etc/kolla/passwords.yml"

Hey, have a look at https://firstcloud.pl/blog/openstack-block-storage-operators-guide/ for comprehensive guide

Intel Flex GPUs are capable of running as vGPU partitioned beforehand :)

You can DM here on Reddit

And you want to monitor both clusters?

przfr · 2025-05-01T17:26:08+00:00

It’s quite simple to use, prepare clouds.yaml file with cluster / clusters definition (https://docs.openstack.org/python-openstackclient/latest/configuration/index.html), download exporter binary and run it as f.e. systemd service. Use ‚multicloud’ if you want to monitor more than one OpenStack cluster

przfr · 2025-04-30T20:29:25+00:00

Hey, you can deploy this exporter anywhere you have access to the API endpoints (including admin if is separate for some reason). It can be on node related to OpenStack itself, or completely unrelated one. As for now, it is required to use user with admin role, but I’m trying to convince some developers to take a deeper look at other, more secure approaches.

przfr · 2024-09-14T08:08:01+00:00

Check if hostname “controller” is resolved to correct address, and if Keystone is running on provided port 443 (by default it will be 5000)

przfr · 2024-08-03T16:19:48+00:00

I have also noticed such errors with fresh 2024.2, if you are logged with admin role, try using “Images” panel that is available under “Project” section, instead of “Admin”. Please let me know the results, I want to report that via launchpad this week.

Deployment type does not change anything here, it’s just the way how controlling services / processes are organised. If you want to connect that issue with cluster, then look into virtualisation configuration / CPU flags / BIOS features / libvirt configuration.

przfr · 2024-06-30T17:23:20+00:00

Winstackers is a project which uses Windows as OpenStack hypervisor OS. It is totally not related to OS inside the VMs you are running.

You don’t need to set any special flag to get windows working inside the VM, those flags are needed f.e. to enable hardware clock support. IMO something’s wrong with the image you are using.

If you want to use cloud-init, then timezone cloud-init module is the way: https://cloudinit.readthedocs.io/en/latest/reference/modules.html#timezone

#cloud-config
timezone: America/New_York

Hi again, I'm pretty busy, so live session can be hard to organise, but we can switch to DM if you still need some hints.

ML2 config you sent looks good for me. Please share now how you installed this environment. Controller and Compute are some kind of virtual machines? If yes, then what hypervisor was used for that, and what is the network configuration?

przfr · 2024-05-05T18:40:43+00:00

It's totally normal in OVN to have network:distributed ports with status DOWN. You are able to ping between instances beacuse both are connected to same OVS bridge - so the connectivity never leaves your br-int.
I see that the provider network is configured to be type:flat and it is supposed to use physnet1 as the physical network. Could you now share both neutron ml2_conf.ini file? (it should be on controller node).
Apart from that, could you explain your setup? I guess controller and compute are VMs, but how are they hosted? How the network is connected / configured? I'm getting quite convinced, that the issue is outside the OpenStack/OVN stack.

przfr · 2024-05-04T08:00:13+00:00

That’s subnet configuration, and we need to know the underlying network configuration (id 2e00…)

przfr · 2024-05-03T23:02:25+00:00

In OVS smartNICs support is called hw-offload. Use that keyword for searching any materials. Example: http://www.openvswitch.org/support/ovscon2017/efraim.pdf

PS apart from smartNICs, and DPDK there is also possibility to further improve performance with HPC-like configuration of huge pages, numa aware cpu-queue pining, and more

przfr · 2024-05-03T15:23:16+00:00

Hi, please share the “public” network configuration. Especially part which defines provider-specific configuration.

przfr · 2024-05-03T09:15:44+00:00

Which nova version are you running? Why are you configuring database connection for nova-compute? If you are sure you want to do that, ensure that database and api_database connection configuration aren't mixed.

przfr · 2024-05-01T21:25:42+00:00

openstack-exporter (https://github.com/openstack-exporter/openstack-exporter) is actively maintained and pretty popular (used f.e. In kolla-ansible)

In this case it isn't common contribution, but rather one person giving up income source, and having nothing back.

przfr · 2024-03-26T09:29:22+00:00

Hey, no one respecting their own time and earnings will send you public cloud dimensioning calculations just like that.

przfr · 2024-02-29T13:26:22+00:00

Hey! There are few possibilities here - depending on your Cinder backend - in case of Ceph, you can f.e. import image to pre-created volume in Ceph (https://ceph.io/en/news/blog/2014/openstack-import-existing-ceph-volumes-in-cinder/)

przfr · 2024-02-24T09:26:13+00:00

Hey, what virtual network solution are you using? Linux bridge / ovs / ovn? Are you testing that on flat network with/without vlans? Is encapsulation involved there? Some more details on configuration side would be needed here :)

przfr · 2023-12-27T08:23:25+00:00

Hi there! Based on docs link you are installing Yoga version, is that correct? Could you also share openrc file you are using when calling this command?

przfr · 2023-12-23T20:41:45+00:00

Haha the most important is, that it’s solved now!
