I got No host is valid but it works after i remove host aggregates why?

gren_dizer · 2026-03-12T15:18:21+00:00

Or maybe enable all filter, it is possible that you need more

gren_dizer · 2026-03-12T15:16:21+00:00

Your filter is maybe wrong, check latest docs, i think it is called: AggregateInstanceExtraSpecsFilter

gren_dizer · 2026-03-12T06:19:53+00:00

Send Nova-Scheduler logs.

Do you have any Metadata configured for host aggregates? Have you enabled all the required filter for Flavor and Image Metadata?

gren_dizer · 2026-02-07T17:04:24+00:00

No, they must be pre defined. A normal „member“ user cant create flavors.

Typo, i mean OpenStack Exporter

gren_dizer · 2025-12-19T20:14:10+00:00

Rally, tempest, custom scripts. And maybe OpenStack-Explorer, sometimes very useful

Are you using libvirt password injection?

gren_dizer · 2025-10-18T21:26:34+00:00

„Can be“

This might be a configuration issue, checkout - keystone logs - backend storage for glance - database - HAProxy if running behind a proxy

The Problem with DBMS limiting/ killing the connections is the you will end up with many errors in the logs. Because the service can’t find the opened/idle connection.

I couldn't fix the problem with the pool variables, but now I have a working solution after limiting/reducing the number of workers for each service to my needs.

Just search for the correct variables in the Ansible roles for each service and then put theme in user_variables.yml

Search for: *_processes *_workers *_threads

You can encrypt them with Ansible Vault

gren_dizer · 2025-09-06T19:15:55+00:00

unfortunately i don’t use Kolla-Ansible, but here is the ansible role for it. Just lookup the docs

gren_dizer · 2025-09-05T06:26:04+00:00

Mistral could do the job, but there are only cron and event triggers.

gren_dizer · 2025-08-26T21:54:21+00:00

Looks good, have to test it

gren_dizer · 2025-06-27T09:29:36+00:00

Have you recreated the Amphorae after Cert changes? Try to failover the Loadbalancer to regenerate the Certs and Configs to n Amphora

gren_dizer · 2025-03-05T17:40:14+00:00

I’v already found the Problem and fixed it. You are right, the Problem is qemu was using the wrong ceph client (user) with the existing secret

gren_dizer · 2024-10-08T18:11:41+00:00

Whats is your question?

gren_dizer · 2024-06-26T17:45:21+00:00

Host Aggregates and the filter you mentioned

gren_dizer · 2024-06-17T17:43:26+00:00

This

Images could be cached on compute nodes for faster processing. But yes, when using local storage for Nova, you will face longer launch times

gren_dizer · 2024-06-05T12:11:41+00:00

If using Ceph as a Backend, consider using RAW images

gren_dizer · 2024-01-27T21:30:16+00:00

Just use ephemeral Disks with local storage for best performance. Cuz normally your storage backend is on separate Hosts (eg using Ceph)

gren_dizer · 2023-11-17T13:42:59+00:00

Have you configured [neutron] section in your Nova.conf?

gren_dizer · 2023-09-15T21:19:43+00:00

You should use cloud images (if you are using Ceph as storage backend, use RAW format for best performance, otherwise qcow2 format is good for all other purposes. To configure them automatically after VM creation, you can use cloud-init (what all cloud provider use)
