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
The Getting Started With Parallels Virtuozzo Containers 4.7 for Linux guide will help you install and
run Parallels Virtuozzo Containers 4.7 on your server. You will also learn the basics of working with
Containers—how to create a Container, start and stop it, install additional software in it, and the
like.
Organization of This Guide
The guide is organized in the following way:
• Chapter 1, Preface, provides an overview of available information sources shipped with
Parallels Virtuozzo Containers 4.7, introduces the main Parallels Virtuozzo Containers notions,
and lists the requirements for installing the Parallels Virtuozzo Containers 4.7 software.
• Chapter 2, Installation in a Nutshell, is a quick reference list sketching out the steps required
to install Parallels Virtuozzo Containers 4.7.
• Chapter 3, Parallels Virtuozzo Containers Installation, explains how to install Parallels
Virtuozzo Containers 4.7 on your server including the installation and configuration of both the
Host operating system and Parallels Virtuozzo Containers software itself.
• Chapter 4, Parallels Virtuozzo Containers Tools, contains brief instructions on setting up
Parallels Management Console and Parallels Virtual Automation—tools for managing Hardware
Nodes and Containers.
• Chapter 5, Container Management, describes the main operations you can perform on
Containers: create new Containers, start and stop them, manage applications inside
Containers, and so on.
