Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.
In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization. Xen is an open-source software project that provides high-performance, resource-managed virtualization on the x86 processor architecture. It allows multiple operating system instances to run concurrently on a single physical computer. Xen manages the computer's hardware resources so they are shared effectively among the operating system instances, called domains. So what does all this mean? It means that by using Xen virtualization, you can run and use several different operating systems at the same time on a single computer. Full article
