“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.  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.

Search all Xen Project mailing lists using MarkMail (not secure):

All Xen Project mailing lists are archived using the MarkMail system at xen.markmail.org. Often you will find an answer for a question by searching here!

Mailing List Usage

Xen Project mailing lists have a web as well as an email interface.

  • Send an email command to mylist-request@lists.xenproject.org (mylist may for example be xen-announce ) with one of the following commands in the subject line. Common commands are help, subscribe and unsubscribe. Alternatively, you can use the  SUBSCRIBE  buttons below.
  • Go to https://lists.xenproject.org/mailman/listinfo/mylist (mylist may for example be xen-announce) and use the web interface to subscribe, unsubscribe or log into the list management interface.
  • You can send a note to a Xen Project mailing list, without being subscribed to it. But your post will be moderated.
  • If you have problems, please send an e-mail to community dot manager at xenproject dot org.

Special Mailing Lists

private@

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

publicity@

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.

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.

What About XenServer Questions?

Many people are confused about the relationship between Xen Project and XenServer. XenServer, now called Citrix Hypervisor, 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 Citrix Hypervisor as well, so for most Citrix Hypervisor -related issues, you will do best by starting with one of the support channels described at citrix.com.
