Welcome to VDD-Project.org: The official Virtual Distro Dispatcher Project website. |
|
 Virtual Distro Dispatcher is an innovative way for Linux distributions dispatching for LAN environment. My name's Flavio Bertini and this project comes from my degree thesis. The main VDD's feature, is its Trashware based laboratory. Our1 research started setting up a lot of obsolete hardware coming from old PCs trashing activites of companies. A lot of people brought us a huge quantity of old PCs for free. Trashware groups, helped us to create a costless distributed environment, whose aim is to supply for Internet access, word processing software and many other things to that people which cannot afford a new workstation. Trashware gave us the possibility to realize both teaching and development environment especially using Open Source software and Operating Systems like GNU/Linux. 1. Research is going ahead in cooperation with Ing. Davide Lamanna - Department of Computer Science at "La Sapienza" University of Rome |

Salvatore Cristofaro joined the VDD Project. Welcome Salvatore. He is a student like me who decided to contribute in the VDD Project development. During his stage period (still in progress) at the Dipartimento di Informatica e Sistemistica "Antonio Ruberti", he brought a large contribute to this research. He gave VDD the possibility to experiment new alternatives to UML, such as Xen, and he studied many possibilities to speed up the whole system also setting up a RAID architecture. With his precious contribute we were able to rebuild VDD in another Computer Laboratory at the our Department of Computer Science. New workstations support the overall system and VDD's performances are increased actually. Now we have two last generation Gentoo Linux based Server, a Gigabit Ethernet LAN and a few thin clients to make tests. We are also studying for a HPC Clustering system to be applied to VDD even though there are many difficulties in finding the right one which fits our necessities. Also the LTSP configuration files have been updated with new entries, especially the dhcp server configuration file. You may contact Salvatore at  . |

Part of the contents of this website came from other resources, especially from User Mode Linux and LTSP official sites. The author don't want to copy or distribute copyrighted material without owner's authorization. All what you read here came from personal experience, and it's aim is to tell you how our work and research are going ahead. Here you will find a non-profit-making documentation. If you think I did some mistake or I published some protected material, please contact me soon. I will only use Free and Open Source software and projects. In order to explain in the best way what my purposes are, I have to publish how UML and LTSP work. |

I'm sorry. Yes I know, my website is terribly outdated. Research has just begun again. We are at work to study how to increase VDD performances, to find out alternative methods to dispatch virtual Linux distributions, and much more.
We expect good results about performances because the hardware we use at our Department (DIS) Laboratory is very recent. So, the performance analysis section mustn't be considered as definitive. I'll publish new results as soon as possible, once the new stage of our research has been reached. Note that, skas4 patch has been released. That patch must be applied both to the guest and the host kernel sources. That's great! Now we can run UML in skas4 mode also on x86_64 architectures without any problem, and obtaining great performances. I hope to update my website soon (time permitting  ) with new research results. I hope you understand, Flavio |
