“If it hasn’t happened in an email list or forum, it hasn’t happened”
Open Source Axiom

Mailing Lists are the lifeblood of the Xen Project.  We welcome the community to participate in the development of the Xen Project, and encourage you to be familiar with mailing list etiquette:

  • Post in plain text (i.e. not HTML), word-wrapped to somewhere around 72 characters.
  • Don’t top-post: reply in-line below the text you’re replying to.
  • Trim the quoted material in your reply to only include the bits you are responding to.
  • Start a new thread for a new bug (don’t just reply to a random email from the list).
  • 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 on the list may be subscribed to the list.

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

Info Subscribe Unsubscribe


This is a list to coordinate content for the Xen Project blog, articles in the open source and Linux press, other media, press activities, to coordinate attendance and submissions for open source and industry events and anything else to promote the Xen Project. The list is open for people in the community who care about promoting the Xen Project. The list is also archived. To join, please email the Community Manager.

This e-mail alias is intended for reporting security vulnerabilities in Xen Project software (this also covers the situation where an existing published changeset is retrospectively found to be a security fix). List membership is restricted to members of the Xen Project Security Response Team and thus invite only and obviously, there is no public archive. For more information on how the Xen Project handles security vulnerabilities, see the Xen Security Problem Response Process.

Organizations who want to become a member of the Xen Project predisclosure list to receive pre-disclosure of security advisories and who meet the criteria outlined in the Xen Security Problem Response Process should become members of this mailing list and submit their application through this mailing list as outlined in Xen Security Problem Response Process. The list is open to all community members who care about security and although pre-disclosure membership applications are evaluated based on strict criteria, all applications are open for review and comment by community members.
