Feature Name

OpenStack using Qpid.

Summary

Provide an alternative to using RabbitMQ as the AMQP backend for an OpenStack deployment. This requires a new module inside of OpenStack nova.

Owner

Name: Russell Bryant
Email: rbryant at redhat dot com

Current status

Targeted release: Fedora 17
Last updated: 2012-01-09
Percentage of completion: 100%

Detailed Description

OpenStack deployments currently use RabbitMQ as the AMQP backend for messaging between OpenStack nova services on different nodes. This feature will allow the use of Qpid as an alternative.

Benefit to Fedora

With this feature in place, OpenStack administrators have more choice about what infrastructure they would like to put in place for their cloud.

Scope

This is primarily an upstream development effort. We must develop a new module that will be incorporated into OpenStack nova to support using Qpid. We aim to get this completed and integrated into the OpenStack Essex release. At that point we will just need to make sure that the new module is properly packaged and is compatible with the version of Qpid in Fedora.

How To Test

Install the qpid-cpp-server package.
Start the qpidd service.
Set --rpc_backend=nova.rpc.impl_qpid in /etc/nova/nova.conf
Use OpenStack nova as usual from there. For example, one could follow the test day test cases.

User Experience

The user experience will be the same.

Dependencies

None.

Contingency Plan

If this feature is not completed in time, it will get pulled and bumped to the next release. No other feature depends on this one.

Documentation

Upstream feature blueprint
The Getting Started with OpenStack Nova page will be updated with information on how to use Qpid.

Release Notes

OpenStack: Support for using Qpid as the messaging backend for nova.
