Project Ideas for GSoC 2012

This page is used to list project ideas for Google Summer of Code (GSOC) 2012. Xen will apply as a mentoring organization again.

Key Google Pages


Project Ideas


  • Be creative
  • Be specific: what do you want to be implemented; if at all possible provide an indication of size and complexity as described above to make it easier for a student to choose ideas
  • If you are willing to mentors those ideas, add your name and email to the idea.
  • If you're an interested student, add your name and email next to the idea. It is ok to have several students interested by one idea.
  • Aspiring students need to get in touch with the community manager via to register their interest

New Project Ideas

Please add new ideas with a description or mail if in doubt. - This is now open for 2012 GSoC!

Port XCP Toolstack to ARM (unconfirmed) XCP Mike McClurg <> Size: Medium/Large. Knowledge: Debian packaging; compiling for Linux on ARM; basic C, Python and OCaml A team of core Xen engineers has just finished porting the Xen hypervisor to the unreleased ARM A15 platform. In preparation for new A15 hardware, we'd like to make sure that the XCP toolstack runs on on current ARM hardware in emulated-Xen mode. This project would involve modifying the XCP toolstack build system to run on current ARM hardware, and produce an XCP toolstack that will run in emulated-Xen mode.
Virtulazation of the CPU Performance Monitoring Unit (unconfirmed) XCP Marcus Granado <> Size: Unknown. Skills: C, kernel/hypervisor hackery Right now, the CPU PMU (performance monitoring unit) is not virtualized, therefore in general it is not possible to run hardware counter profilers (such as Linux oprofile, FreeBSD hwpmc or similar tools for Windows) inside guest domains. The goal of the project would be to allow these hardware counter profilers to run inside guest domains.
Improvement of OpenXenManager, the XCP GUI XCP Mike McClurg <> Size: Medium. Knowledge: Python and GTK OpenXenManager is a free, open-source, multi-platform GUI for both Xen Cloud Platform and XenServer. It has many nice features, but could use some bug fixes and new features.
Clean segment under tree snapshots of HLFS, a sub-project of Cloudxy (unconfirmed) XEN Chen Lijun <>, Kang Hua <> Size: Medium. Knowledge: C, block driver, File system and HDFS HLFS, sub-project of Cloudxy, is a distributed vm image storage system for XEN. HLFS(Hadoop Log Structure Filesystem,actually named Hadoop Log Structure Block System is more proper) provides highly available block level storage volumes that can be attached to XEN virtual machines by its tapdisk driver — Similar projects in KVM region is sheepdog,however in different architecture. For details, you can visit or (In Cheinese).We hope to accomplish "clean segment under tree snapshots" feature during GSOC 2012. This one will involve:

1. Implement mechanism of segment clean - it involves "mid-snapshot segment clean" and "over-snapshot segment clean". so you can do it in normal way(pull data) and "map/reduce" way. 2. Implement strategy of segment clean - it will take into account that how to avoid IO contention between clean operation and vm disk access operation
