[libvirt] Looking for project ideas and mentors for Google Summer of Code 2014
KVM & libvirt: you are welcome to join the QEMU umbrella organization like last year. What is GSoC? Google Summer of Code 2014 (GSoC) provides funding for students to work on open source projects for 12-weeks over the summer. Open source organizations apply to participate and those accepted receive funding for one or more students. How we are participating QEMU has participated, together with KVM and libvirt, in past years and I would like to continue that tradition this year. We now need to collect a list of project ideas on our wiki. We also need mentors to volunteer. http://qemu-project.org/Google_Summer_of_Code_2014 Project ideas Please post project ideas on the wiki page below. Project ideas should be suitable as a 12-week project that a student fluent in C/Python/etc can complete. No prior knowledge of QEMU/KVM/libvirt internals can be assumed. http://qemu-project.org/Google_Summer_of_Code_2014 Mentors Please add your name to project ideas you are willing to mentor. In order to mentor you must be an established contributor (regularly contribute patches). You must be willing to spend about 5 hours per week from May 19 to August 18. I have CCed the 8 most active committers since QEMU 1.5.0 but everyone is invited. Official timeline: https://www.google-melange.com/gsoc/events/google/gsoc2014 Stefan

I've updated wiki with a libvirt idea. But I can sense more to come later as I have some time to think about it :)
Great, thanks! I have added my QEMU block layer ideas too. Deadline for the organization application is 14th of February. As part of the application form we need to show our list of ideas. Thanks for posting your project ideas so that our list is ready. Stefan
Hi all, i offer part of my free time as mentor. Cheers, Giorgio 2014-02-06 13:27 GMT+01:00 Stefan Hajnoczi <stefanha@gmail.com>:

From my original email: "In order to mentor you must be an established contributor (regularly contribute patches)."
I couldn't find any commits from you in QEMU, libvirt, or Linux. Did I miss your contributions? Stefan

I'd like to add persistent dirty bitmap as an idea but I seem to have no account on wiki, so I'll just reply here, please help with review and update the page if it makes sense. (Who could create an account for me, BTW?) Project Idea Below ================== Incremental backup of block images ---------------------------------- Summary: Implement persistent incremental image backup. Users want to do regular backup of VM image data to protect data from unexpected loss. Incremental backup is a backup strategy that only copies out the "new data" that is changed since previous backup, to reduce the overhead of backup and improve the storage utilization. To track which part of guest data is changed, QEMU needs to store image's "dirty bitmap" on the disk as well as the image data itself. The task is to implement a new block driver (a filter) to load/store this persistent dirty bitmap file, and maintain the dirty bits while the guest writes to the data image. As a prerequisite, you also need to make the design of this bitmap file format. Then, design test cases and write scripts to test the driver. The persistent bitmap file must contain: 0. Magic bits to identify the format of this file. 1. Bitmap granularity (e.g. 64 KB) 2. The actual bitmap (1 TB disk @ 64 KB granularity = 2 MB bitmap) 3. Flags including a "clean" flag. The "clean" flag is used to tell whether the persistent bitmap file is safe to use again. When QEMU opens the persistent dirty bitmap, it clears the "clean" flag. When QEMU deactivates and finishes writing out the dirty bitmap, it sets the "clean" flag. If the QEMU process crashes it is not safe to trust the dirty bitmap; a full backup must be performed. Make use of this flag in the driver to limit the performance overhead.

Now I've got two because Paolo and Kevin helped me at the same time :). Thank you! Fam
Hi all, I would like to add fault tolerance mechanism. 2014-02-07 11:10 GMT+01:00 Fam Zheng <famz@redhat.com>:

I'm assuming you would contribute as a student rather than a mentor, since I am not familiar with contributions from you to either libvirt or QEMU. In that case, do not worry. The page is only listing project ideas from the mentors, and it is certainly possible for student to propose their own projects. This has already happened in the past. Thanks, Paolo

Hope it's not too late: just added the VT-d emulation proposal. Jan

Excellent! I was going to ping you today because the project you mentored last year was quite successful. Thank you for posting your idea for 2014. Stefan

It's not too late. Ideas page must be ready when students will discover the list of accepted organizations on Monday 24th. I'm not GSoc admin here, but on LibreOffice ;) -- Cedric

The project ideas list is linked from the organization application form and Google folks have mentioned messy/incomplete project ideas lists when giving feedback to orgs that were not accepted. This is why it's worth having the project ideas list ready. But Cedric is right that we can still add project ideas later. I set the hard deadline at March 10th when students begin applying. Stefan

There are only a few days left before the hard deadline (March 10th) but I wanted to mention one possible project which I think is worth considering: Integration of Libvirt and CRIU to allow live-migration (and snapshots?) for containers In [1] you can find more details about the reasons why this feature would make sense together with a first analysis by Daniel about what to consider for the design. I am not applying as a student and I am not offering myself as a mentor (I do not qualify as a mentor), I Just wanted to point out a possible interesting (and challenging) project. I am afraid it would be too challenging for a 12 weeks projects, but I'll let you decide that. Having said that, I would be happy to help with the testing and reviews if needed. /Chris [1] http://www.redhat.com/archives/libvir-list/2013-November/msg00055.html

Agreed, it seems like it could be too much for someone new to libvirt and containers. But definitely an exciting feature idea. Stefan

I don't know how you're usually handling those sort of things, but in LibreOffice project we have just created a GenialIdeas page for ideas lacking mentors, or a slightly too big for GSoc... so that interested people can pick it later. On a mailing list, that idea is likely to be lost sooner or later ;) -- Cedric
