OpenVZ vs VirtualBox: What are the differences?

  1. Architecture: OpenVZ is a container-based virtualization system that shares the host operating system's kernel, providing better performance but only supporting Linux guests. In contrast, VirtualBox is a full virtualization software that emulates physical hardware, enabling the creation of virtual machines running various operating systems, including Windows, Linux, and macOS.

  2. Resource Allocation: OpenVZ allocates resources dynamically, meaning that resources are shared among containers based on demand. VirtualBox, on the other hand, allocates a fixed amount of resources to each virtual machine, providing more isolation but potentially lower utilization efficiency.

  3. Performance: Due to its container-based approach, OpenVZ offers better performance than VirtualBox since there is less overhead from simulating hardware. VirtualBox, being a full virtualization solution, requires more resources and incurs higher overhead, impacting performance compared to container-based virtualization.

  4. Operating System Support: OpenVZ supports only Linux guests since it shares the host kernel, while VirtualBox supports a wide range of operating systems, making it more versatile for users who require different guest OS support.

  5. Management and Maintenance: OpenVZ requires less management overhead since it runs on a single, shared kernel, simplifying updates and patches. VirtualBox, being a full virtualization solution, requires individual management for each virtual machine, making it more complex to maintain in environments with multiple VMs.

  6. Security: OpenVZ provides lower levels of isolation between containers since they share the host kernel. VirtualBox offers higher security by providing individual virtual machines with their own simulated hardware, decreasing the risk of security breaches affecting other VMs.

In Summary, OpenVZ and VirtualBox differ in terms of architecture, resource allocation, performance, operating system support, management and maintenance requirements, and security features.

OpenVZ

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2.

Virtuozzo leverages OpenVZ as its core of a virtualization solution offered by Virtuozzo company. Virtuozzo is optimized for hosters and offers hypervisor (VMs in addition to containers), distributed cloud storage, dedicated support, management tools, and easy installation.

Portability;No hardware virtualization required;Guest Additions: shared folders, seamless windows, 3D virtualization;Great hardware support;Multigeneration branched snapshots;VM groups;Clean architecture; unprecedented modularity;Remote machine display
A container (CT) looks and behaves like a regular Linux system. It has standard startup scripts; Software from vendors can run inside a container without OpenVZ-specific modifications or adjustment; A user can change any configuration file and install additional software; Containers are completely isolated from each other (file system, processes, Inter Process Communication (IPC), sysctl variables); Processes belonging to a container are scheduled for execution on all available CPUs

What are some alternatives to VirtualBox, OpenVZ?

Docker

Docker

The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere

LXD

LXD

LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.

Proxmox VE

Proxmox VE

It is a complete open-source platform for all-inclusive enterprise virtualization that tightly integrates KVM hypervisor and LXC containers, software-defined storage and networking functionality on a single platform, and easily manages high availability clusters and disaster recovery tools with the built-in web management interface.

VMware vSphere

VMware vSphere

vSphere is the world’s leading server virtualization platform. Run fewer servers and reduce capital and operating costs using VMware vSphere to build a cloud computing infrastructure.

LXC

LXC

LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.

rkt

rkt

Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.

KVM

KVM

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V).

Qemu

Qemu

When used as a machine emulator, it can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance. When used as a virtualizer, it achieves near native performance by executing the guest code directly on the host CPU. it supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, it can virtualize x86, server and embedded PowerPC, 64-bit POWER, S390, 32-bit and 64-bit ARM, and MIPS guests.

Parallels Desktop

Parallels Desktop

Parallels Desktop for Mac allows you to seamlessly run both Windows and MacOS applications side-by-side with speed, control and confidence.

Vagrant Cloud

Vagrant Cloud

Vagrant Cloud pairs with Vagrant to enable access, insight and collaboration across teams, as well as to bring exposure to community contributions and development environments.
