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.
