Mailing List

"If it hasn't happened in an email list, it hasn't happened,"  -- Open Source axiom

Mailing Lists are the lifeblood of the Xen Project.  If you intend to actively participate in the development of the Xen Project, you will need to become familiar with the mailing lists and the mailing list etiquette:

  • Please post in plain text (i.e. not HTML), word-wrapped to somewhere around 72 characters.
  • Please don't top-post.
  • Please start a new thread for a new bug (don't just reply to a random email from the list).
  • Please don't email bugs directly to Xen Project developers. Keep the conversation on the list where other people (and search engines) can see it.
  • When you reply to a mail, ensure that you reply to the list and all author(s). Not all posters to the list may be subscribed to the list.

What About XenServer Questions?

Many people are confused about the relationship between Xen Project and XenServer.  XenServer is a distribution of Xen Project the same way that Ubuntu or SUSE are distributions of Linux.  You might go to a Linux kernel mailing list to talk about kernel bugs in your distribution, but the bulk of your issues are probably best handled by asking questions of the distribution itself.  This is true with XenServer as well, so for most XenServer-related issues, you will do best by starting with one of the XenServer support channels described at  The people in that community understand the context of their distribution very well and can most likely guide you to a resolution.

Special Mailing Lists


This list is for maintainers of all Xen teams, and key developers that have been invited by maintainers. This list is intended to be used only when privacy implications or similar prevent usage of a public list. Example usage may be to let other community members know of absence (due to holidays, maternity/paternity leave, etc.) and to arrange cover. Another example may be to ask other team members for advice on how to respond to a difficult situation in the community. Any conversations that should have been started on a public list, will be forwarded to an appropriate public list. 

This list is invite only and is not archived. Community members can subscribe, but approval in line with Mailing List Conventions is required.

For more information on how the Xen Project handles security vulnerabilities, see the Xen Security Problem Response Process.
