I have been lately involved in an ongoing project Baadal Cloud Computing Platform in my institute, which has got me interested in oVirt for a potential GSoC project. I was going through the virt-sparsify integration project idea. I have gone through the architecture documentation on the oVirt website. As far as I understand, the virt-sparsify integration needs to be done on the VDSM daemon, and it's control is either going to be completely independent of ovirt-engine (for example running it once every 24 hours), or it's something that is centrally controlled by the ovirt-engine through XML/RPC calls. The details are not specified in the project ideas page. I would like to ask - 1. What would be the proposed ideal implementation? (Central-Control or Independent-Control) 2. Is virt-sparsify usage going to be automated or administrator-triggered, or a combination of both? There are some aspects of the idea, which I would like to discuss before I start working on a proposal. It's not necessary that an automated usage of virt-sparsify is limited to any simple idea. Architecture documentation states that ovirt-engine has features like Monitoring that would allow administrators (and possibly users) to be aware of vm-guest performance as well as vm-host performance. I am not very sure about how this data is collected, Is it done through MoM, or Is this directly done by VDSM, or is someone else doing this (for hosts). It would be great if someone can explain that to me. This information about vm-guest usage and vm-host health can help in determining how virt-sparsify is to be used. I am also not very clear about the Shared Storage component in the architecture. Does oVirt make any assumptions about the Shared Storage. For example, the performance difference between running virt-sparsify on NFS as compared to running it (if possible) directly on storage hardware. If the Storage solution is necessarily a NAS instance, then virt-sparsify on NFS mount is the only option. Right now, I am in the process of setting up oVirt on my system, and getting more familiar with the architecture. Regarding my experience. I am acquainted with both Java and Python. I have little experience with JBoss, but I have worked on some other Web Application Servers like web2py and Play Framework. My involvement in Baadal Platform has got me acquainted with libvirt/QEMU, the details of which I have mentioned below (if anyone is interested). Please advise me about the things that I am missing about this project. If there are some implementation details that I need to know, kindly help me with that too. Looking forward. Thanks. ===================== Utkarsh IIT Delhi Ongoing project details - Article (Old) http://www.cc.iitd.ernet.in/CSC/index.php?view=article&id=123:baadal-...
