Great. I have put up a more detailed description on the QEMU GSoC 2011 page: http://wiki.qemu.org/Google_Summer_of_Code_2011#QCOW2_.3C-.3E_QED_image_converter Please be aware that organizations have not yet been selected by Google and that GSoC planning is still in the early stages. I want to make sure that your expectations and the amount of upfront effort you invest at this early stage reflect that so you're not disappointed if things don't come together. > I am now planning to start reading their source code. What do you suggest? > Are there any other specific things that I should read about? btrfs has an ext3 conversion mode that could be inspiring: https://btrfs.wiki.kernel.org/index.php/Conversion_from_Ext3 You could tackle open bugs to familiarize yourself with the codebase: http://goo.gl/DMxOD Or this: which is faster, qemu-img convert -f <format> -O <format> <src-image> <dst-image> or cp <src-image> <dst-image>? What about for raw images, shouldn't that be the same speed as cp(1)? Poke around the source code, profile it, understand what it's doing, think about ways to improve it. No need to do everything, just doing part of this will give you background on QEMU's block layer. Contributing patches is a good way get up to speed and show your skills. If time doesn't permit that, just think about the problem and how you intend to solve it, and feel free to bounce ideas off me. Stefan
