Open Source Virtualization (LFS462)

Open Source Virtualization takes a deep dive into KVM (Kernel-based Virtual Machine) and Xen, the most popular hypervisor virtualization technologies in the open source ecosystem, as well as the deployment and use of containers. Built by experts in the field of virtualization, this course provides the technical background to understand the components required to build and administer a modern virtual IT infrastructure. 

This course is focused on problems typically faced in the enterprise world. The lectures are filled with examples of how KVM, Xen and containers can be used in business environments as well as practical lab sessions that let participants gain a real�­-world perspective of common virtualization problems and how to address them.c

Prerequisites

This course is for technical IT professionals interested in building a reliable, efficient and open virtualization infrastructure with KVM. Students are expected to be well versed in Linux command line usage, shell scripting and text file editing.

Course Outline

At the end of the training, attendees will have acquired the skills needed to: 

• Understand the role KVM and Xen play in the virtualization ecosystem
• Know how to assemble KVM and other components into a robust and efficient virtual IT infrastructure
• This course is designed to work with a wide range of Linux distributions, so you will be able to apply these concepts regardless of your distro.
