Release Process

• nova (and other projects under the compute program in governance) are released through the standard openstack release process: https://github.com/openstack/releases/blob/master/README.rst
• Server side release checklist is found in Nova/ReleaseChecklist

Code Review Dashboards

• Many Nova reviewers use dashboards to help them decide what to review. Nova/GerritDashboards tracks some of our favorites.

Other resources

Nova subteams

The Nova team meets weekly: Meetings/Nova.

In addition to a project-wide Nova gathering each week, there are some sub-teams. These sub-teams get together to discuss work going on in a focused area of Nova.

Code Review Subteam

Sub-teams don't need permission. They can be around for short or long periods of time.

A common pattern is an ad-hoc group of people, focusing on a sub set of reviews. They generally co-ordinate on here: https://etherpad.openstack.org/p/stein-nova-subteam-tracking

For each sub-team, the etherpad usually includes:

• list of people in the group (IRC nicks)
• list of patches the sub-team have reviewed, and think are ready for nova-core to approve
• list of patches the sub-team are focusing their reviews on
• May link to a regular meeting, but that is strictly optional

Over time, it is hoped, some sub-teams may become trusted enough to count as a +2. Even without counting as a +2, the review focus and implied prioritisation is still very valuable.

Sub-team Meetings

Some subteams are more formal, with a regular meeting and a wiki page.

• The linked wiki page should include:
  • The mission of the team
  • A regular meeting time
  • A coordinator / point of contact
  • Meeting Agenda
  • Links to logs from previous meetings
• A sub-team representative should regularly attend the main Nova meeting to provide a sub-team status report.
• A sub-team is *not* exclusively responsible for an area of code. Anyone is welcome to contribute anywhere. However, you are encouraged to communicate regularly with others working in the same area as you and sub-teams help encourage that.
• A sub-team is about organizing development efforts, but not necessarily setting direction for the project in a given area. Approval of patches is still done by the nova-core team and it is beneficial to publish designs to the openstack-dev mailing list for vetting in advance.

Active Sub-teams

TODO - this list can get out-of-date, need a better approach.

• Scheduler
• Cellsv2
• NovaAPI
• Libvirt
