Dear CentOS gsoc mentors, my name is Marios and I am a student from Greece. I participated in gsoc last year in LTTng project and I am interested in participating again this year in the CentOS project. I found the projects you proposed extremely interesting and I am really confused which one to choose to make my proposal for. So, I would like to ask some clarifying questions, which are groupped per project. I address my questions here but I am more than willing to talk with the equivalent mentors in IRC or mail. My questions are: * Centos cloud storage - Is glusterfs a prerequisite for the program? Is it possible to use another fs, eg CephFS, because I am familiar with the Ceph architecture, since I have partially worked with that. * Lightweight Cloud instance contextualisation tool Can I have some more details about this project especially as far as the lightwieght part is concerned. As I imagine this tool will not be CentOS specific, right? * Xen based Hypervisor in a Box According to the ideas page "the aim of this task is to build an installer instance". So, will the result be like a live CD where the user can try different CentOS versions, or a new instance that from the time is installed xen is running and several CentOS VMs can be initiated. * App to trim containers Is this project about docker containers or containers in general? Are there any specific ideas and tools in mind behind that project or it is more of a research project? * Cloud in a box Is there any prerequisite about the cloud software that should be used? There are a lot of choices eg OpenStack, oVirt, synnefo As you can understand from my questions I am more interested in cloud and virtualization projects and CentOS is among the few gsoc projects that offer me this chance. I am looking forward your reply. Best regards, Marios
