Launchpad bugs are used to track known issues and defects in OpenStack software.

Bugs reference

Here are the different fields available in Launchpad bugs, and how we use them within the OpenStack project.


New The bug was just created
Incomplete The bug is waiting on input from the reporter
Confirmed The bug was reproduced or confirmed as a genuine bug
Triaged The bug comments contain a full analysis on how to properly fix the issue
In Progress Work on the fix is in progress, bug has an assignee
Fix Committed The branch containing the fix was merged into master
Fix Released The fix is included in the proposed/* branch, a past milestone or a past release
Invalid This is not a bug
Opinion This is a valid issue, but it is the way it should be
Won't Fix This is a valid issue, but we don't intend to fix that


This should be set when the status reaches Confirmed stage. It is a combination of short-term impact (unavailability of a feature), long-term impact (data corruption, security breach), number of people affected, and presence of a documented workaround. Use these as guidelines:

Critical Data corruption / complete failure affecting most users, no workaround
High Data corruption / complete failure affecting most users, with workaround
Failure of a significant feature, no workaround
Medium Failure of a significant feature, with workaround
Failure of a fringe feature, no workaround
Low Small issue with an easy workaround
Any other insignificant bug
Wishlist Not really a bug, but a suggested improvement
Undefined Impact was not assessed yet

Note that presence of Critical bugs will delay the release.

Assigned To

The person currently working to fix this bug. Must be set by In progress stage.


The milestone we need to fix the bug for, or the milestone/version it was fixed in.


Free-form tags you can use to search bugs with. Here is the list of official tags.

Bugs lifecycle

Bugs go through multiple stages before final resolution.


When you find a bug, you should file it against the proper OpenStack project using the corresponding link:

Make sure there is no bug already filed for the same issue, then enter the details of your report. It should at least include:

  • The release, or milestone, or commitid corresponding to the software that you are running

When this is done, the bug is created with:

  • Status: New

Confirming & prioritizing

This stage is about checking that a bug is real and assessing its impact. If you are lacking information to properly reproduce or assess the importance of the bug, you should ask the original reporter for more information and set the bug to:

  • Status: Incomplete

Once you have reproduced the issue (or are 100% confident that this is indeed a valid bug), you should set:

  • Status: Confirmed

If you're a core developer or a member of the project bug supervision team, you should also prioritize the bug:

  • Importance: <Bug impact> (see above)

Debugging (optional)

This optional stage is about determining how to fix the bug and posting the solution in the comments. Sometimes the implementation of the fix will be straightforward and you would jump directly to bugfixing, but in some other cases, you would just post your complete debugging analysis and give someone else the opportunity of fixing the bug. Then you should ask a core developer or bug supervisor to set:

  • Status: Triaged


At this stage, a developer will work on a fix. During that time, in order to avoid duplicating the work, he should set:

  • Status: In progress
  • Assignee: <yourself>

When the fix is ready, he will propose the change and get it reviewed.

Note that Gerrit will automatically set the status and assignee when a change is proposed that mentions the bug number.

After the change is accepted

Once the change is reviewed, accepted, and has landed in master, it will automatically move to:

  • Status: Fix Committed

When the fix makes it into a milestone or a proposed/* release branch, it will automatically move to:

  • Milestone: Milestone the bug was fixed in
  • Status: Fix Released

Bug list maintainers

In 2014, the role of a "bug czar" was proposed on the mailing list. Since most probably most projects face the same issues when managing their bugs, it makes sense that the bug czars of the different projects work together. Right now these are:

  • Neutron: Kyle Mestery (IRC: mestery)
  • Nova: Markus Zoeller (IRC: markus_z)
  • Cinder: TBD (the role is not yet officially implemented; interim contact "jgriffith")
  • <other-projects-here>
