OpenVZ
OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

Virtuozzo
Virtuozzo Containers is an operating system virtualization solution that maximizes your investment in server hardware. Virtuozzo Containers is uniquely suited to Cloud server virtualization, enabling near instant provisioning and on-the-fly modification of hosting and Cloud server plans while delivering maximum density, cost efficiency and application performance.
OpenVZ and Virtuozzo are both virtualization platforms, but they have some key differences in terms of their architecture and capabilities.

1. Architecture: OpenVZ is based on container virtualization, where a single Linux kernel is shared among multiple containers or virtual environments. Each container operates as an isolated entity, sharing the host's resources. Virtuozzo, on the other hand, combines container virtualization with a hypervisor layer. It utilizes a modified version of the OpenVZ kernel along with a proprietary hypervisor, enabling the creation of both containers and full virtual machines.

2. Scalability: Virtuozzo offers more scalability options compared to OpenVZ. With Virtuozzo, you can create both containers and full virtual machines, allowing for greater flexibility in resource allocation and management. OpenVZ, on the other hand, focuses solely on container-based virtualization, which may limit the scalability options depending on the requirements of your workload.

3. Management Tools: Virtuozzo provides a comprehensive set of management tools and a web-based control panel that simplifies the administration and monitoring of both containers and virtual machines. It offers advanced features like live migration, high availability, and automatic load balancing. OpenVZ, on the other hand, has a more minimalistic approach to management tools, requiring users to rely on command-line utilities for container management.

4. Commercial Support: Virtuozzo is primarily offered as a commercial product, and it provides professional support services for its users. OpenVZ, on the other hand, is an open-source project that relies on community support, although some companies offer commercial support for OpenVZ deployments.
