Virtuozzo

Virtuozzo provides OS‑level virtualization that lets a single physical server host multiple isolated virtual environments, each with its own file system, network stack, and resource limits. The platform implements containers that share the host kernel while maintaining strong separation, allowing workloads to run side‑by‑side without interference.

Developers and system administrators use Virtuozzo to consolidate services, test software in distinct environments, and manage resource allocation across applications. Its tools include command‑line utilities for creating, starting, stopping, and monitoring containers, as well as mechanisms for configuring CPU, memory, and storage quotas per environment.

What distinguishes Virtuozzo is its focus on server‑grade container management with built‑in isolation and resource control, offering a stable, production‑ready solution for running many independent workloads on a single host.
