Version Control

As of February 2013 Xen is maintained using the GIT version control system. Previously, the Xen Project was maintained in Mercurial and mirrors of git into mercurial are still provided.

Staging

All changes to Xen Project software, whether to mainline or a stable branch, are initially pushed to a staging branch. These staging branches are then tested using the automated test system. When the tests passed the staging trees are automatically pushed to the primary trees.

Repositories

Primary Xen Project Repository

The main Xen Project repository is git://xenbits.xen.org/xen.git. This single repository contains branches for each of the stable maintenance branches as well as development and staging branches.

Stable release branches (stable-4.4, stable-4.3, ...)

More information on stable releases can be found in Xen Project Maintenance Releases.

The latest stable release from this branch is available from http://xenproject.org/downloads/xen-archives.html.

These branches contain the in-progress work on the next release on the previous stable branch and are named stable-X.Y (and staging-X.Y) where X.Y is the version.

Xen development branch (master)

These branches contain the development version of Xen Project software.

TAGS

Releases are tagged using the following conventions:

  • RELEASE-X.Y.Z (e.g. RELEASE-4.4.0 for Xen 4.4, RELEASE-4.3.2 for Xen 4.3.2)
  • Release candidates are tagged X.Y.Z-rc{number} with {number} > 0

Other components hosted or mirrored on xenbits

As well as the Xen Project repository, a Xen system contains several other components either developed as part of Xen Project or incorporated from other projects.

Qemu

Qemu is used to provide device emulation for HVM guests. It can also be used to provide PV backends for some PV devices.

More information can be found at QEMU Upstream

Qemu Xen Tree

The qemu-xen code is maintained upstream in the qemu.org git trees. In addition the Xen project also maintains its own stable branch of qemu, based on the upstream stable branches with a small number of additional fixes for Xen.

It can be found on xenbits in qemu-xen.git with a branch for each release of Xen named stable-VERSION, e.g. stable-4.10.

Qemu Xen Traditional Trees

The qemu-xen-traditional fork is maintained on xenbits in qemu-xen-traditional.git. There are branches for each release of Xen named stable-VERSION e.g. stable-4.10.

Guest Firmware

Guest firmware is used with HVM guests.

SeaBIOS

OVMF is the Legacy BIOS firmware used with qemu-xen.

http://xenbits.xen.org/gitweb/?p=seabios.git;a=summary

Upstream: http://seabios.org/SeaBIOS

OVMF

OVMF is the UEFI firmware, it is available with qemu-xen.

http://xenbits.xen.org/gitweb/?p=ovmf.git;a=summary

Upstream: http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=EDK2

ROMBIOS

ROMBIOS (used with qemu-xen-traditional) is contained in the main Xen tree at tools/firmware/rombios.

Other components hosted elsewhere

Kernels

Linux

Note that the Linux branches are not hosted on xenbits.

For more information on selecting suitable domain 0 kernels please see XenDom0Kernels.

The recommended Linux kernel branch is the upstream stable release branch:

For development the recommended branch is:

To see what's queued for the next release, the next merge window, and other work in progress:

  • The Xen subsystem maintainers' tip.git tree.

Additional information:

Cloning git repositories over http

For the benefit of those behind firewalls most git repositories hosted on xenbits are also exposed via http.

For a repository git://xenbits.xen.org/foo.git you can clone via http using http://xenbits.xen.org/git-http/foo.git.

Mercurial mirrors of Xen Project software

In addition to the git repositories of Xen Project software, there is a Mercurial repository for each branch:

As well as these previous staging and stable branches can be found at http://xenbits.xen.org/hg/.
