=== hacluster - default transport ===

For the 15.04 charm release, the hacluster charm will continue to use multicast as its default transport option for cluster communications.

Unicast is generally more universally usable across all Juju providers - we'll be switching the default for 15.07 including automatic migration and re-configuration of existing multicast clusters. Instructions will also be provided for users who wish to continue to use the multicast transport option.

=== Neutron deployments without using the neutron-api charm ===

Summary

The 15.04 OpenStack Charm release includes updates for the following charms:

  • ceilometer
  • ceilometer-agent
  • ceph
  • ceph-radosgw
  • cinder
  • cinder-ceph
  • glance
  • hacluster
  • heat
  • keystone
  • neutron-api
  • neutron-openvswitch
  • nova-cloud-controller
  • nova-compute
  • openstack-dashboard
  • quantum-gateway
  • rabbitmq-server
  • swift-proxy
  • swift-storage
  • percona-cluster

These release notes complement the 15.01 charm release notes in terms of charm features delivered since the last Ubuntu release.

New Charm Features

Neutron - Distributed Virtual Router

Neutron - Router High Availability

Percona Cluster - Improved HA failure detection

The percona-cluster charm now ensures that the access Virtual IP is always co-located with an active, up-to-date instance of Percona XtraDB Cluster.

Deployment from source

EXPERIMENTAL FEATURE

The following charms now have support for deploying OpenStack directly from git repositories:

  • cinder
  • keystone
  • glance
  • nova-cloud-controller
  • nova-compute
  • neutron-api
  • quantum-gateway
  • neutron-openvswitch

This feature is enabled by using the new 'openstack-origin-git' configuration option; this can be used to configure a minimal or expanded list of repositories to collate and install - see the README in each charm for specific details.

Further deploy from source enablement is expected during the 15.07 charm development cycle.

Deprecation Notices

quantum-gateway

15.04 is the last release of the 'quantum-gateway' charm; for 15.07 it will be renamed 'neutron-gateway'. Migration instructions will be provided for 15.07 release.

MySQL HA with Ceph

The original HA implementation of OpenStack used the MySQL charm in-conjunction with Ceph to provide a traditional active/passive shared block device HA mysql option.

Percona XtraDB Cluster, as provided by the percona-cluster charm, provides an active/active MySQL configuration with no requirement for a shared block device.

Users of the original MySQL HA option should migrate to a Percona XtraDB Cluster deployment between now and the 15.10 charm release, where support for MySQL with Ceph will be removed.

hacluster - default transport

For the 15.04 charm release, the hacluster charm will continue to use multicast as its default transport option for cluster communications.

Unicast is generally more universally usable across all Juju providers - we'll be switching the default for 15.07 including automatic migration and re-configuration of existing multicast clusters. Instructions will also be provided for users who wish to continue to use the multicast transport option.

Neutron deployments without using the neutron-api charm
