Replace debian-bookworm with debian-trixie for the base job in order to use a newer version of qemu that has patch [0] that addresses an issue where test_boot_cloned_encrypted_volume fails when run on a fast machine. The default python in debain-trixie is Python 3.13, which is a supported python version for the Gazpacho development cycle [1]. Also, updated the package prereq file for some necessary packages that aren't included by default in trixie.

Devstack Ceph Plugin
Overview
Devstack plugin to configure Ceph as the storage backend for openstack services
As part of stack.sh:
- Creates a Ceph cluster for use with openstack services using Ceph orchestrator
- Configures Ceph as the storage backend for Cinder, Cinder Backup, Nova, Manila, and Glance services
- (Optionally) Sets up & configures Rados gateway (aka rgw or
radosgw) as a Swift endpoint with Keystone integration. Set
ENABLE_CEPH_RGW=Truein yourlocalrc - Supports Ceph cluster running local or remote to openstack services
As part of unstack.sh | clean.sh:
- Tears down the Ceph cluster and its related services
Usage
To get started quickly, just enable the plugin in your
local.conf:enable_plugin devstack-plugin-ceph https://opendev.org/openstack/devstack-plugin-ceph
Run stack.sh in your devstack tree and boom! You're good
to go.
Ceph is setup as the default storage backend for Cinder, Cinder Backup, Glance, Manila and Nova services. You have the ability to control each of the enabled services with the following configuration in your
local.conf:ENABLE_CEPH_CINDER=True # ceph backend for cinder ENABLE_CEPH_GLANCE=True # store images in ceph ENABLE_CEPH_C_BAK=True # backup volumes to ceph ENABLE_CEPH_NOVA=True # allow nova to use ceph resources ENABLE_CEPH_MANILA=True # allow manila to use CephFS as backend (Native CephFS or CephFS via NFS)
Change any of the above lines to False to disable that
feature specifically.
Manila's CephFS Native driver that supports native Ceph protocol is enabled by default. To use CephFS NFS-Ganesha driver that supports NFS protocol add the setting:
MANILA_CEPH_DRIVER=cephfsnfsIf you'd like to use a standalone NFS Ganesha service in place of
ceph orchestrator deployed ceph-nfs service, set:
CEPHADM_DEPLOY_NFS=FalseMake sure that the manila plugin is enabled before
devstack-plugin-ceph in the local.conf file.
- Then run
stack.shand wait for the magic to happen :)
Known Issues / Limitations
- Rados Gateway with Keystone for Swift - works on Ubuntu only
- Tempest test failures when using RGW as swift endpoint
- Tempest fails due to verify-tempest-config erroring out, when using RGW as swift endpoint
