KVM vs VirtualBox: What are the differences?

Comparison between KVM and VirtualBox

KVM and VirtualBox are both popular options for virtualization, but they have some key differences.

  1. Performance: KVM, being a type 1 hypervisor, provides better performance compared to VirtualBox, which is a type 2 hypervisor. KVM has direct access to the host hardware, resulting in faster execution and better overall performance.

  2. Compatibility: VirtualBox offers compatibility with various operating systems, including Windows, macOS, and Linux, making it a popular choice for desktop virtualization. On the other hand, KVM is primarily used in Linux environments and is well-integrated with the Linux kernel.

  3. Management: KVM is managed through command-line tools and APIs, making it suitable for advanced users and system administrators. VirtualBox, on the other hand, provides a user-friendly graphical interface that makes it easier for beginners to manage virtual machines.

  4. Resource Allocation: KVM allows for dynamic allocation of resources like CPU and memory to virtual machines. It also provides better control over resource utilization and allocation. In contrast, VirtualBox has limitations in resource management, making it less suitable for resource-intensive applications.

  5. Hardware Support: KVM has better hardware support, including features like nested virtualization, which allows running virtual machines within virtual machines. VirtualBox, although it supports a wide range of hardware, doesn't have the same level of hardware compatibility as KVM.

  6. Community Support: VirtualBox has a larger user community and a vast amount of online resources available for support and troubleshooting. KVM, on the other hand, has a more niche user base, mostly consisting of Linux enthusiasts and developers.

In Summary, KVM excels in performance, hardware support, and resource allocation, while VirtualBox offers better compatibility, user-friendly management, and larger community support.

KVM

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.

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

What are some alternatives to VirtualBox, KVM?

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.

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.

Parallels

Parallels

It is an application and desktop virtualization software vendor that offers management and delivery platforms for Apple macOS and Microsoft Windows desktop deployments.

VMware Fusion

VMware Fusion

It gives Mac users the power to run Windows on Mac along with hundreds of other operating systems side by side with Mac applications, without rebooting. It is simple enough for home users and powerful enough for IT professionals, developers and businesses.

Xen

Xen

It is a hypervisor using a microkernel design, providing services that allow multiple computer operating systems to execute on the same computer hardware concurrently. It was developed by the Linux Foundation and is supported by Intel.

VMware vSAN

VMware vSAN

It is enterprise-class, storage virtualization software that, when combined with vSphere, allows you to manage compute and storage with a single platform. You can reduce the cost and complexity of traditional storage and take the easiest path to hyperconverged infrastructure and hybrid cloud. Evolve to an integrated hyperconverged infrastructure (HCI) solution with vSAN to improve business agility, all while speeding operations and lowering costs.

Oracle VM Server

Oracle VM Server

It is a zero license cost server virtualization and management solution that makes enterprise applications easier to deploy, manage, and support. Backed worldwide by affordable enterprise-quality support for both Oracle and non-Oracle environments, it reduces operations and support costs while increasing IT efficiency and agility.

Virtuozzo

Virtuozzo

It is an operating system-level server virtualization solution designed to centralize server management and consolidate workloads, which reduces overhead by reducing the number of physical servers required. Organizations use it for server consolidation, disaster recovery, and server workload agility.
