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>

Cluster policies


oVirt allows you to configure the clusters in load balancing mode or power saving mode. When setting up oVirt, it is recommended to determine the clusters for one of the policies. For a cluster, you can assign only one policy. By default, there are two policies available:

  • Even Distribution: In this mode, the load is distributed to all nodes in the cluster. To apply the policy, all virtualization hosts are measured by the load on the CPU.

  • Power Saving: In this mode, the load is distributed on a minimum number of nodes in order to save energy.

For setting up the cluster policy to the cluster, perform the following steps:

  1. Select the Clusters tab in the resource pane. In the list of clusters, select the desired cluster and click on Edit.

  2. In the dialog box, select the Cluster Policy section in the left-hand side of the window. In the right-hand side of the window, choose either one of the policies in the Select Policy section: Even_Distributed or Power_Saving.

  3. When the policy chosen...
