The first attempt ® Condor is a program developed by the University of Wisconsin to allow desktop computers to The initial solution we devised was to install VMWare® within a native Linux install, and then to install Windows inside VMWare®. The steps harness idle time to perform computationally intensive operations. See were: “http://www.cs.wisc.edu/condor/” for more information about Condor®. 1. Install Linux as the native host operating system Why do you need it? 2. Install Condor inside Linux 3. Install VMWare® inside Linux ® Condor® provides free computing cycles for scientific and research use, which extends current 4. Install Windows inside VMWare super-computing resources by adding additional computing time. We installed this solution on approximately 200 lab computers across OU’s campus during the summer of 2005. During testing, we noticed a significant performance decrease using Windows inside VMWare®. To alleviate this problem, we changed VMWare® to use raw disk mode. This mode significantly increased disk performance inside VMWare®. If this is so simple, why can’t I just install it? Once we deployed VMWare® in the labs, several more issues appeared: ® Most scientific and research programs are designed for Linux, but most desktops are running • CD/DVD Burning from inside VMWare did

The Hypervisor is the one which provides the complete virtualization environment which will intend to virtualize as much as hardware and systems which will include the CPUs, Memory, network interfaces and so on. Because of the virtualization technologies such as the KVM and others such as ESXi, there has been a significant decrease in the usage if the resources and decrease in the costs involved.
  • Authentication Services in Mobile Ad-Hoc Networks

    Authentication Services in Mobile Ad-Hoc Networks

    Authentication Services in Mobile Ad-hoc Networks LOgiciels-Réseaux Willy Jiménez 08013 -LOR Hakima Chaouchi Maryline Laurent-Maknavicius _______________________________________________________________________________ Authentication Services in Mobile Ad-hoc Networks ABSTRACT The deployment of wireless ad hoc networks is useful for people when they desire to communicate even if they are not connected to any infrastructure, with the purpose of playing games, sharing internet connection, or exchange files. In some ad hoc scenarios, they might know each other, so they can establish trusted relationships. However, if the number or users and mobility increase then it is more complicated to trust all users and a security mechanism is required. Few researches has been done in this field to find security solutions for MANETs deployments; one of them proposes a framework where the traditional AAA services are distributed inside the network with the idea of allowing secure exchange of services that could be chargeable. Based on this framework, we evaluate technical solutions, focusing mainly on the Authentication service; in order to have real implementations. One possibility is using virtualization technology to offer a de-centralized authentication service. Another solution is the development of a secure version of a routing protocol that uses a de-centralized authentication service as a previous requirement to allow any node to join the ad hoc routing domain.

To my near family, for their accumulated efforts of improving our collective life. And to Maria Alexandra Siso, Robert Baumgartner, Alyssa Juday and Marc Ramirez for keeping me sane. i ACKNOWLEDGMENTS I extend my gratitude to everyone that has made my work possible. I express my thanks to the communities of VirtualBox, StackOverflow, ServerFault and Ubuntu Help as well as the Reddit communities for Linux and Networking for answering all my technical questions in detail and without prejudice I would like to thank Dr Anna Calveras for her guidance and patience. ii RESUMEN Nuestro objetivo fue la creación de una red compuesta de máquinas virtuales conectadas de forma específica a través de interfaces virtuales y con una seria de protocolos pre configurados que permiten la fácil creación de túneles IPv6 y traductores IPv6 a IPv4. Esta red les permitirá a profesores y estudiantes analizar y observar trafico IPv6 real sin la necesidad de una red física. La red está compuesta de múltiples Máquinas Virtuales Ubuntu y una Máquina Virtual Windows 7. La red puede ser fácilmente instalada en un ordenador corriendo Ubuntu o una distribución basada en Ubuntu. Un USB arrancable fue desarrollado para usar la red en un ordenador sin la necesidad de una instalación o de un sistema operativo especifico. Todas las máquinas virtuales Linux pueden fácilmente ser controladas a través de una terminal sin necesidad de clave utilizando una serie de scripts.

  • Porting the QEMU Virtualization Software to MINIX 3

    Porting the QEMU Virtualization Software to MINIX 3

    Porting the QEMU virtualization software to MINIX 3 Master's thesis in Computer Science Erik van der Kouwe Student number 1397273 [email protected] Vrije Universiteit Amsterdam Faculty of Sciences Department of Mathematics and Computer Science Supervised by dr. Andrew S. Tanenbaum Second reader: dr. Herbert Bos 12 August 2009 Abstract The MINIX 3 operating system aims to make computers more reliable and more secure by keeping privileged code small and simple. Unfortunately, at the moment only few major programs have been ported to MINIX. In particular, no virtualization software is available. By isolating software environments from each other, virtualization aids in software development and provides an additional way to achieve reliability and security. It is unclear whether virtualization software can run efficiently within the constraints of MINIX' microkernel design. To determine whether MINIX is capable of running virtualization software, I have ported QEMU to it. QEMU provides full system virtualization, aiming in particular at portability and speed. I find that QEMU can be ported to MINIX, but that this requires a number of changes to be made to both programs. Allowing QEMU to run mainly involves adding standardized POSIX functions that were previously missing in MINIX. These additions do not conflict with MINIX' design principles and their availability makes porting other software easier. A list of recommendations is provided that could further simplify porting software to MINIX. Besides just porting QEMU, I also investigate what performance bottlenecks it experiences on MINIX. Several areas are found where MINIX does not perform as well as Linux. The causes for these differences are investigated.
