Google Summer of Code 2013

From QEMU

Introduction

QEMU is going to apply as a mentoring organization for Google Summer of Code 2013. This page contains our ideas list and information for students and mentors.

Preliminary information: This page is under construction as we plan to apply for 2013. Please contribute but remember that Google has not accepted organizations for 2013 yet.

Please note that QEMU, as a GSoC organization, also includes the following projects:

  • The Linux Kernel's KVM module
  • Libvirt, the virtualization library

Organization

Any Question, request or problem regarding QEMU in GSoC, please contact the following people. IRC is usually the quickest way to get an answer, see below for methods of communication.

Information for students

We require students to provide at least the following information in their applications:

  • Contact information (email, irc nick, phone number)
  • A general personal description (skills, past experiences and open source contributions, if any)
  • Why QEMU and why this project
  • A detailed description of the approach the student will take

Please get in touch before applying so we can arrange for an IRC interview and get to know each other. Students who do not contact the mentor cannot be accepted.

VERY IMPORTANT: Submitting a patch and having it merged by QEMU or KVM increases your chances of being accepted.

QEMU projects

TITLE

Improving the Win32 and Win64 ports of QEMU

Summary: QEMU supports Windows (both 32-bit and 64-bit), but the limited amount of testing caused performance to suffer and bugs to creep in release after release. This project aims at fixing QEMU bugs affecting Windows platforms, and adding new features such as migration.

KVM projects

Libvirt projects

Introducing job control to the storage driver

Currently, libvirt support job cancellation and progress reporting on domains. That is, if there's a long running job on a domain, e.g. migration, libvirt reports how much data has already been transferred to the destination and how much still needs to be transferred. However, libvirt lacks such information reporting in storage area, to which libvirt developers refer to as the storage driver. The aim is to report progress on several storage tasks, like volume wiping, file allocation an others.

  • Skill level: intermediate

More intelligent virsh auto-completion

Even though there's already some auto-completion in virsh, it is not enough. For better user experience, virsh should auto complete objects to virsh commands, e.g. "start <TAB><TAB>" lists not only options that the start command knows, but list of inactive domains as well. Moreover, the same applies to command options.

  • Skill level: beginner

Introduce API to query IP addresses for given domain

One of the most desired APIs in libvirt that still hasn't been implemented. The aim is to get/guess list of IP addresses assigned to domain. There are several ways to get such list: asking guest agent, snooping for domain traffic, parsing dnsmasq lease file, etc.

  • Skill level: beginner

Ability to run qemu-{system-}arm

Libvirt is nowadays tight to PCI bus based qemus: qemu-i386 and qemu-x86_64. However, with recent development of ARM architecture, as ARM based devices become more and more popular, the voice calling for ARM support in libvirt is getting stronger. The libvirt's assumption every domain has at least one PCI bus needs to be dropped and code adapted accordingly.

Information for mentors

Mentors are responsible for keeping in touch with their student and assessing the student's progress. GSoC has a mid-term evaluation and a final evaluation where both the mentor and student assess each other.

The mentor typically gives advice, reviews the student's code, and has regular communication with the student to ensure progress is being made.

Being a mentor is a significant time commitment, plan for 5 hours per week. Make sure you can make this commitment because backing out during the summer will affect the student's experience.

The mentor chooses their student by reviewing student application forms and conducting IRC interviews with candidates. Depending on the number of candidates, this can be time-consuming in itself. Choosing the right student is critical so that both the mentor and the student can have a successful experience.
