Glossary

Application template is a template used to install a set of applications in Containers. See also Template.

Container (or regular Container) is a virtual private server, which is functionally identical to an isolated standalone server, with its own IP addresses, processes, files, its own users database, its own configuration files, its own applications, system libraries, and so on. Containers share one Hardware Node and one OS kernel. However, they are isolated from each other. A Container is a kind of 'sandbox' for processes and users. Container 0 and Container 1 are used to designate the Hardware Node and the Service Container, respectively.

Container 0 is used to designate a Hardware Node where the Virtuozzo Containers software is installed.

Container 1 is used to designate the Service Container.

EZ template is a template file that points to a repository with the packages that comprise the template. Unlike standard templates, EZ templates cannot be updated because the repository stays the same. However, the packages in the repository can be updated.

Hardware Node (or Node) is a server where the Virtuozzo Containers software is installed for hosting Containers. Sometimes, it is marked as Container 0.

Host Operating System (or Host OS) is an operating system installed on the Hardware Node.

MAC address stands for Media Access Control address, a hardware address that uniquely identifies each Node in a network. The MAC layer interfaces directly with the network media. Consequently, each different type of network media requires a different MAC layer.

OS template (or Operating System template) is used to create new Containers with a preinstalled operating system. See also Template.

Package set is a synonym for Template.

Parallels Infrastructure Manager (or Infrastructure Manager) is a tool designed for managing Hardware Nodes and all Containers residing on them with the help of a standard Web browser on any platform.

Parallels Management Console (or Management Console) is a Virtuozzo Containers management and monitoring tool with graphical user interface. It is used to control individual Hardware Nodes and their Containers. Management Console is cross-platform and runs on both Microsoft Windows and Linux workstations.

Parallels Power Panel is a means for administering personal Containers with the help of a standard Web browser (Internet Explorer, Mozilla, etc.) on any platform.

Parallels Virtuozzo Containers (or Virtuozzo Containers) is a complete server automation and virtualization solution allowing you to create multiple isolated Containers on a single physical server to share hardware, licenses, and management effort with maximum efficiency.

Private area is a part of the file system where Container files that are not shared with other Containers are stored.

SSH stands for Secure Shell. It is a protocol for logging on to a remote machine and executing commands on that machine. It provides secure encrypted communications between two untrusted hosts over an insecure network.

Service Container is a special Container automatically created on the Hardware Node during the Virtuozzo Containers installation and needed to manage your regular Containers by means of Parallels Infrastructure Manager, Parallels Power Panel, and Parallels Management Console. Sometimes, the Service Container is marked as Container 1.

Standard template is a template file that has inside itself all the re-usable files of all the packages comprising the template. If newer versions of any of these packages appear, a standard template can be correspondingly updated. Compare EZ template.

TCP (TCP/IP) stands for Transmission Control Protocol/Internet Protocol. This suite of communications protocols is used to connect hosts on the Internet.

Template (or package set) is a set of original application files (packages) repackaged for mounting over Virtuozzo File System. There are two types of templates. OS Templates are used to create new Containers with a preinstalled operating system. Application templates are used to install an application or a set of applications in Containers. See also Standard template and EZ template.

UBC is an abbreviation of User Beancounter.

User Beancounter is the subsystem of the Virtuozzo Containers software for managing Container memory and some system-related resources.

VENET device is a virtual networking device, a gateway from a Container to the external network.

Virtual Environment (or VE) is an obsolete designation of a Container.

Virtuozzo Control Center (or VZCC) is an obsolete designation of Parallels Infrastructure Manager.

Virtuozzo File System (VZFS) is a virtual file system for mounting to Container private areas. VZFS symlinks are seen as real files inside Containers.

Virtuozzo Server license is a special license that you should load to the Hardware Node to be able to start using the Virtuozzo Containers software. Every Hardware Node shall have its own Virtuozzo Server license.

Virtuozzo Power Panels (or VZPP) is an obsolete designation of Parallels Power Panel.

Virtual Private Server (or VPS) is an obsolete designation of a Container.

Parallels Agent (or Parallels Agent Protocol) is an XML-based protocol used to monitor and manage a Hardware Node. The Parallels Agent software implements this protocol and is a backend for the Parallels Management Console.
