OpenStack Conference / Design Summit 2011 Sponsored by Citrix

The time has finally come to reveal the agenda for the conference portion of next month’s OpenStack Conference / Design Summit 2011 sponsored by Citrix. The Design Summit agenda is still in active development and will be finalized once the Project Team Leader elections are complete and the new team members are able to offer input into the schedule. Please remember that I reserve the right to make any changes to this agenda; however I am confident that we are past the 95% complete mark. Register for this event here.

OpenStack Developer Activity (March 11 – 18)

Many people have asked for more insight into the developer activities for OpenStack as the large number of code changes and proposals make it difficult to monitor everything happening. In hopes of exposing more of the developer activities, I plan to post a weekly or biweekly blog post on the latest development activities. If you have any ideas for this blog post, please email me at I am always ready to listen to the community for new ideas.

Cactus Branch Merge Proposal Freeze in Effect –
OpenStack Design Summit Registration –

Coming up in OpenStack Cactus…

In a bit more than a week, we will hit FeatureFreeze for OpenStack “Cactus” cycle, so we start to have a good idea of what new features will make it. The Cactus cycle focus was on stability, so there are fewer new features compared to Bexar, but the developers still achieved a lot in a couple of months…

Swift (OpenStack object storage)
The Swift team really focused and stability and performance improvements this cycle. I will just single out the refactoring of the proxy to make backend requests concurrent, and improvements on sqlite3 indexing as good examples of this effort.

Glance (OpenStack image registry and delivery service)
Bexar saw the first release of Glance, and in Cactus it was vastly improved to match standards we have for the rest of OpenStack: logging, configuration and options parsing, use of paste.deploy and non-static versioning, database migrations…

Nova (OpenStack compute)
A lot of the feature work in Nova for Cactus revolved around the OpenStack API 1.1 and exposing features through XenServer (migration, resize, rescue mode, IPv6, file and network injection…).
