Part I Introduction Edit source

1 Virtualization Technology

Virtualization is a technology that provides a way for a machine (Host) to run another operating system (guest virtual machines) on top of the host operating system.

2 Introduction to Xen Virtualization

This chapter introduces and explains the components and technologies you need to understand to set up and manage a Xen-based virtualization environment.

3 Introduction to KVM Virtualization

4 Virtualization Tools

libvirt is a library that provides a common API for managing popular virtualization solutions, among them KVM, LXC, and Xen. The library provides a normalized management API for these virtualization solutions, allowing a stable, cross-hypervisor interface for higher-level management tools. The library also provides APIs for management of virtual networks and storage on the VM Host Server. The configuration of each VM Guest is stored in an XML file.

With libvirt you can also manage your VM Guests remotely. It supports TLS encryption, x509 certificates and authentication with SASL. This enables managing VM Host Servers centrally from a single workstation, alleviating the need to access each VM Host Server individually.

Using the libvirt-based tools is the recommended way of managing VM Guests. Interoperability between libvirt and libvirt-based applications has been tested and is an essential part of SUSE's support stance.

5 Installation of Virtualization Components

Depending on the scope of the installation, none of the virtualization tools may be installed on your system. They will be automatically installed when configuring the hypervisor with the YaST module Virtualization › Install Hypervisor and Tools. In case this module is not available in YaST, install…
