Topics

Xen Developer and Roadmap discussion

Date of insert: 02/03/2013; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Lars Kurth
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: N/A
Skills Needed: N/A
Description: As we are all together, the Xen maintainers and committers should discuss Xen 4.4 roadmap items as well as any other items that need coordination. Alternatively we could consider doing this the day before the Hackathon.
Outcomes: A rough plan for Xen 4.4 and meeting minutes

Xen on ARM "Portathon"

Date of insert: 12/03/2013; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Ian Campbell
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: Not too hard if you are familiar with the hardware and have Linux running
Skills Needed: Mostly C
Description: Xen on ARM has reached the point where it is becoming reasonable to port it to a wider set of hardware. The idea of this session would be to take advantage of the presence of the Xen on ARM developers to port Xen to your hardware. In order to participate you will need:
  • Access to a hardware platform which supports the ARM virtualisation extension which you wish to port Xen to.
    • Could be local access if hardware is portable, otherwise remote serial and power control will be required
    • Software models could also be considered
  • An existing functioning port of Linux >3.8 to the platform
  • Access to datasheets and/or extensive knowledge of the hardware platform
Outcomes: Xen running on some new ARM platforms


Update toolstacks to make use of libxl and/or xl

Date of insert: 12/03/2013; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Ian Campbell
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: Depends on the complexity of the toolstack which needs modifying
Skills Needed: Some C, perhaps knowledge of the C bindings for the language which the toolstack uses.
Description: There are various higher-level toolstacks which make direct use of the xend interfaces (either through xm, sxp or XML/RPC). This project offers an opportunity to collaborate on porting toolstacks to use xl or other modern toolstack interfaces.

This project also covers those who wish to use libxl directly to implement their own toolstack or to port an existing toolstack from other lower-level interface (such as libxc) to libxl.

It is expected that participants will be familiar with the internals of the toolstack the wish to port to libxl/xl
Outcomes: More toolstacks using xl or libxl.


VMFUNC, grant table operations, Intel QuickData engines
