General utilities are intended for performing day-to-day maintenance tasks

vzctl
Utility to control Containers.
vzlist
Utility to view a list of Containers existing on the Node with additional information.
vzquota
Utility to control Virtuozzo Containers disk quotas.

Licensing utilities allow you to install a new license, view the license state, generate a license request for a new license

vzlicview
Utility to display the Virtuozzo license status and parameters.
vzlicload
Utility to manage Virtuozzo licenses on the Hardware Node.
vzlicupdate
Utility to activate the Virtuozzo Containers installation, update the Virtuozzo licenses installed 
on the Hardware Node, or transfer the Virtuozzo license from the Source Node to the Destination
Node.

Container migration tools allow to migrate Containers between Hardware Nodes or within one Hardware Node

vzmigrate
Utility for migrating Containers from one Hardware Node to another.
vzmlocal
Utility for the local cloning or moving of the Containers.
 
vzp2v
Utility to migrate a physical server to a Container on the Node.
vzv2p
Utility to migrate a Container to a physical server.

Container backup utilities allow to back up and restore the Container private areas, configuration files, action scripts, and quota information

vzbackup
Utility to back up Containers.
vzrestore
Utility to restore backed up Containers.
vzabackup
Utility to back up Hardware Nodes and their Containers. As distinct from vzbackup, this utility 
requires the Parallels Agent software for its functioning.
vzarestore
Utility to restore backed up Hardware Nodes and Containers. As distinct from vzrestore, this utility 
requires the Parallels Agent software for its functioning.

Template management tools allow the template creation, maintenance and installation of applications into a Container

vzpkg
Utility to manage OS and application EZ templates either inside your Containers or on the Hardware Node 
itself.
vzmktmpl
Utility to create OS and application EZ templates.
vzveconvert
Utility to convert Containers based on Virtuozzo standard templates to EZ template-based Containers.
vzpkgproxy
Utility to create caching proxy servers for handling OS and application EZ templates.
vzrhnproxy
Utility to create RHN proxy servers for handling the packages included in the RHEL 4 and RHEL 5 OS EZ 
templates.
vzpkgls
Utility to get a list of templates available on the Hardware Node and in Containers.
vzpkginfo
Utility to get the information on any template installed on the Hardware Node.
vzpkgcreat
Create a new package set from binary RPM or DEB files.
vzpkgadd
Utility to add a new template to a Container.
vzpkglink
Utility to replace real files inside a Container with symlinks to these very files on the Node.
vzpkgrm
Utility to remove a template from a Container.
vzpkgcache
Update a set of preinstalled Container archives after new template installation.

Supplementary tools perform a number of miscellaneous tasks in the Hardware Node and Container context

vzup2date
Utility to update your Virtuozzo software and templates.
vzup2date-mirror
Utility to create local mirrors of the Virtuozzo official repository.
vzfsutil
Utility for the VZFS optimization and consistency checking.
vzcache
Utility to gain extra disk space by caching the files identical in different Containers.
vzsveinstall
Utility to create the Service Container on the Hardware Node.
vzsveupgrade
Utility to update the packages inside the Service Container.
vzps
Utility working as the standard ps and top utilities, with Containerrelated functionality added.
vztop
Utility working as the standard ps and top utilities, with Containerrelated functionality added.
vzsetxinetd
Utility to switch some services between a standalone and xinetddependent modes.

vzdqdump
Utility to dump the Container user/group quota limits and grace times from the kernel or the quota file or for 
loading them to a quota file.
vzdqload
Utility to dump the Container user/group quota limits and grace times from the kernel or the quota file or for 
loading them to a quota file.
vznetstat
Utility that prints network traffic usage statistic by Containers.

(in the text and graphical form).
vzreport
Utility to draw up a problem report and to automatically send it to the Parallels support team.
vzhwcalc

Common Terms

Hardware Node
Hardware Node (or HN) is a physical computer that hosts Containers.
Container
Container is functionally identical to an isolated standalone server with its own IP addresses, processes, files, 
users, its own version, its own configuration files, its own applications, system libraries, and so on. Containers
share the same Hardware Node and the same OS kernel. However, they are isolated from each other. Each Container has
a unique numerical ID starting with 1.
Host Operating System
Host Operating System (or Host) is an operating system installed on the Hardware Node. It is also called Container 
0 in contrast to real Containers the IDs of which start with 1.
Template
Template (or package set) is a set of original application files repackaged for mounting over Virtuozzo File System (VZFS).
 There are two types of templates in Virtuozzo:
OS templates which can be used to create new Containers on their
basis and
application templates which can be added to Containers after their creation.
PIM
Parallels Infrastructure Manager (or PIM) is a Web-based management tool designed for Host administrators.
PMC
Parallels Management Console (or PMC) is a remote management tool with a graphical user interface designed for Host 
administrators.
PPP
Parallels Power Panel is a Web-based management tool designed for Container owners.
