Introduction
About Parallels Virtuozzo Containers
Parallels Virtuozzo Containers is a patented OS virtualization solution. It creates isolated partitions
or Containers on a single physical server and OS instance to utilize hardware, software, data center
and management effort with maximum efficiency. The basic Parallels Virtuozzo Containers
capabilities are:
• Intelligent Partitioning—Division of a server into as many as hundreds of Containers with
full server functionality.
• Complete Isolation—Containers are secure and have full functional, fault and performance
isolation.
• Dynamic Resource Allocation—CPU, memory, network, disk and I/O can be changed
without rebooting.
• Mass Management—Suite of tools and templates for automated, multi-Container and multi-
server administration.
The diagram below represents a typical model of the Parallels Virtuozzo Containers system
structure:

Introduction
The Parallels Virtuozzo Containers OS virtualization model is streamlined for the best performance,
management, and efficiency. At the base resides a standard Host operating system which can be
either Windows or Linux. Next is the virtualization layer with a proprietary file system and a kernel
service abstraction layer that ensure the isolation and security of resources between different
Containers. The virtualization layer makes each Container appear as a standalone server. Finally,
the Container itself houses the application or workload.
The Parallels Virtuozzo Containers OS virtualization solution has the highest efficiency and
manageability making it the best solution for organizations concerned with containing the IT
infrastructure and maximizing the resource utilization. The Parallels Virtuozzo Containers complete
set of management tools and unique architecture makes it the perfect solution for easily
maintaining, monitoring, and managing virtualized server resources for consolidation and business
continuity configurations.
About This Guide
This guide provides exhaustive information on the process of installing, configuring, and deploying
Parallels Virtuozzo Containers 4.7 on your system including the pre-requisites and the stages you
shall pass.
The primary audience for this book is anyone interested in installing and putting Parallels Virtuozzo
Containers 4.7 in operation on their servers. To fully understand the guide, you should have strong
Linux system administration habits. Still, no more than superficial knowledge of Linux Server OS is
required in order to learn to perform the basic installation operations.
Organization of This Guide
Chapter 2, Preliminary Operations, explains the fundamentals of planning your Parallels system,
describes hardware and software requirements your system must meet, and sketches out the
steps required to successfully install Parallels Virtuozzo Containers 4.7.
Chapter 3, Installing Parallels Virtuozzo Containers 4.7, focuses on setting up Parallels
Virtuozzo Containers 4.7 on the Hardware Node including the installation and configuration of both
the Host operating system and the Parallels Virtuozzo Containers software itself.
Chapter 4, Setting Parallels Tools to Work, provides information on how to set up Parallels
Management Console and Parallels Virtual Automation—tools for managing Hardware Nodes and
Containers residing on them.

Besides the formatting conventions, you should also know about the document organization
convention applied to Parallels documents: chapters in all guides are divided into sections, which,
in their turn, are subdivided into subsections. For example, About This Guide is a section, and
Documentation Conventions is a subsection.

Introduction
Getting Help
In addition to this guide, there are a number of other resources shipped with Parallels Virtuozzo
Containers 4.7 which can help you use the product more effectively.
• Getting Started With Parallels Virtuozzo Containers 4.7 for Linux. This guide provides basic
information on how to install Parallels Virtuozzo Containers 4.7 on your server, create new
Containers, and perform main operations on them. Unlike this guide, it does not contain
detailed description of all the operations needed to install and set Parallels Virtuozzo Containers
to work (e.g. planning the structure of your network or performing the Parallels Virtuozzo
Containers unattended installation).
• Parallels Virtuozzo Containers 4.7 for Linux User's Guide. This guide provides comprehensive
information on Parallels Virtuozzo Containers 4.7 covering the necessary theoretical
conceptions as well as all practical aspects of working with Parallels Virtuozzo Containers.
However, it does not deal with the process of installing and configuring your Parallels system.
• Parallels Virtuozzo Containers 4.7 for Linux Templates Management Guide. This guide is meant
to provide complete information on Parallels templates—an exclusive Parallels Virtuozzo
Containers technology allowing you to efficiently deploy standard Linux applications inside your
Containers and to greatly save the Hardware Node resources (physical memory, disk space,
and so on).
• Parallels Virtuozzo Containers 4.7 for Linux Reference Guide. This guide is a complete reference
on all Parallels configuration files and Hardware Node command-line utilities.
• Deploying Clusters in Parallels-Based Systems. This document provides information on creating
failover and data sharing clusters in Parallels Virtuozzo Containers-based systems.
