Virtuozzo creates multiple isolated Virtual Private Servers (VPSs) on a single physical server to share hardware, licenses and management effort with maximum efficiency. Each VPS performs and executes exactly like a stand-alone server for its users and applications as it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

VPS performs and executes exactly like an isolated stand-alone server

• Each VPS has its own processes, users, files and provides full root access.
• Each VPS can have its own IP addresses, port numbers, tables, filtering and routing rules.
• Each VPS can have its own system configuration files and can house an application.
• Each VPS can have its own versions of system libraries or modify existing ones.
• For Example: Multiple distributions of Linux can reside on the same physical server.

VPS runs off-the-shelf software without any changes
