Getting Started with oVirt 3.3

By: Alexey Lesovsky

Overview of this book

<p>Virtualization technologies are evolving very rapidly. With advanced capabilities for hosts and guests including high availability, live migration, storage management, system scheduler, and many more, oVirt comes with the latest advancements in the field of open source virtualization. oVirt is built on the powerful Kernel-based Virtual Machine (KVM) hypervisor and on the RHEV-M management server, and it allows you to utilize the most advanced capabilities of virtualization in an easy and efficient way.</p> <p>Getting Started with oVirt 3.3 talks you through the internal structure and working of oVirt 3.3 using a practical, hands-on approach. You will learn how to install and set up your own virtualization infrastructure as well as in what order you should configure your virtualization environment, what features oVirt has, and how to use them. You will also learn how easy it is to create cluster policies to control the operation of a cluster as well as how to create and use a virtual machine template.</p> <p>With this book, you will learn how to run your own data centers in different configurations and about the existing opportunities for creating virtual machines. You will perform the re-balancing of clusters and quickly create dozens of virtual machines. This book will also help you create a network environment and set policies for QoS. You will also learn how to manage users and allocate resources between them. Getting Started with oVirt 3.3 teaches you everything you need to know about oVirt 3.3 and shows you how to get the most out of the technology quickly and effectively.</p>

Hosts


The main components of the infrastructure are the virtualization hosts called Hosts.

Start and run the VMs on the hosts. All hosts are members of the cluster. Joining Hosts into clusters accomplishes many goals, for example, creating a logical structure in the virtualization environment or creating a separated group of servers for special purposes. Also, hosts can be joined into clusters by CPU type.

Configuring hosts

The configuration of virtualization hosts in oVirt is simple and requires only a physical server that meets the hardware requirements with CentOS/RHEL preinstalled and accessible via SSH. This host must have a preconfigured VDSM repository. This issue is described in Chapter 2, Installing oVirt, in the oVirt Engine setup section.

After clicking on Configure Hosts in the Guide Me wizard, a dialog box for adding virtualization host is displayed, which has the following three sections:

  • General: Here you should enter the basic settings for the new host. These settings are given...
