rabbitmq: Bump default rabbit_qos_prefetch_count from 1 to 50

2026-07-23T16:44:21+00:00

rabbit_qos_prefetch_count was previously set to 1, the lowest value permitted by oslo.messaging when rabbit_stream_fanout is enabled (oslo.messaging requires prefetch_count > 0 for stream queues, since the stream protocol needs a positive credit window to make progress). However, non-zero is not the same as optimal. RabbitMQ's own quorum queue documentation recommends the opposite of what a prefetch of 1 provides: "Quorum queues also benefit from consumers using higher prefetch values to ensure consumers aren't starved whilst acknowledgements are flowing through the system and allowing messages to be delivered in a timely fashion." -- https://www.rabbitmq.com/docs/quorum-queues With rabbit_quorum_queue enabled by default alongside rabbit_stream_fanout, prefetch=1 forces every quorum-queue consumer (nova-conductor, neutron-server, cinder-volume, etc.) into fully serialized delivery: RabbitMQ will not deliver the next message to a channel until the previous one has been acked. Combined with a small worker count, this can turn a burst of RPC traffic into a queueing delay long enough to exceed rpc_response_timeout, surfacing as a false-positive MessagingTimeout with no actual broker outage. Bump the default to 50. This keeps the value legal for stream queues (still > 0), keeps a bound on how much a single consumer can hold in flight, but gives quorum-queue consumers enough headroom to avoid unnecessary serialization and consumer starvation under load. This is a shared value across all services using oslo_messaging_rabbit, so it is intentionally conservative rather than tuned per-service; operators with specific throughput requirements can still override om_rabbitmq_qos_prefetch_count.

kolla-toolbox: Template clouds.yaml and use it

2026-04-15T12:17:01+00:00

Basically Ansible heuristic obfuscation methods mark auth: that we pass to openstack.* modules as no_log_values and then obfuscates it's values in other runs (which then end up as **** e.g. auth_url, domain_id, domain name, etc) Example return: "domains": [ { "description": "The ******** domain", "id": "VALUE_SPECIFIED_IN_NO_LOG_PARAMETER", "is_enabled": true, "links": { "self": "********/v3/domains/********" }, "name": "Default", "options": {}, "tags": [] } This patch adds clouds.yaml to files templated for kolla-toolbox (but without the password) and only uses password from Kolla-Ansible secrets instead of storing that on disk on all of the nodes.

Fix ulimit defaults for Debian family container engines

2026-02-25T11:04:40+00:00

When using containerd, ulimits are not enforced by default. On Debian-based systems this commonly results in missing nofile limits and service startup failures. This change introduces sane default ulimit values for Debian-based distributions while keeping existing EL9 behavior unchanged.
