What is Virtuozzo Hybrid Server?

Virtuozzo Hybrid Server is a bare-metal virtualization platform that uniquely combines container-based and hypervisor-based virtualization on a single host. This hybrid architecture delivers higher density and more efficient resource utilization compared to traditional solutions.

Key Features

• Hybrid Architecture: Run both lightweight OS containers and full KVM virtual machines on the same physical server.
• High Density: Up to 3x more workloads per server compared to traditional hypervisors thanks to container technology.
• Live Migration: Move running containers and VMs between hosts with zero downtime for maintenance.
• Storage Optimization: Built-in distributed storage with thin provisioning and deduplication.

Architecture

Virtuozzo runs directly on bare metal with a modified Linux kernel. Containers share the host kernel for minimal overhead, while KVM provides full hardware isolation for VMs. A unified management layer handles both workload types transparently.

Use Cases

• Hosting Providers: Maximize server density with mixed container/VM offerings.
• Enterprise IT: Consolidate legacy VM workloads alongside modern containerized apps.
• Development Environments: Rapidly provision isolated dev/test environments.
