![]() Affordability: Since it’s open source and available as a Linux kernel module, KVM costs nothing out of the box.ĭeveloped by Oracle, VirtualBox is an open source virtualization software that is a type 2 hypervisor.Security: As part of the Linux kernel source code, KVM benefits from rigorous development and testing processes, as well as continuous security patching.It also enables clustering for thousands of nodes, which helps set the foundation for a cloud-based infrastructure. Scalability: The KVM hypervisor automatically scales to respond to heavy loads once the number of VMs increases.There are plenty of experts to go to for support and questions. This high level of maturity means it’s well developed and very debugged. Maturity: KVM is more than 15 years old and has more than 1,000 code contributors.This gives KVM an inherent advantage in terms of performance and efficiency. This means it doesn’t have to load an underlying OS and has direct access to the underlying hardware without having to contend for virtualization with other software such as other operating systems and device drivers. Performance: KVM is a type 1 or “bare metal” hypervisor, meaning it runs directly on the host machine’s physical hardware.Advantages of KVMĪ KVM hypervisor enables full virtualization capabilities, giving each VM all the features of a physical system, including the basic input/output system (BIOS) and hardware, such as processors, memory, storage, and network cards. A hypervisor is software that creates and runs virtual machines (VMs), allowing a host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing. The Linux kernel is the main component of a Linux operating system (OS) that acts as the core interface between a computer’s hardware and its processes. ![]() KVM, also known as the KVM hypervisor, is a virtualization module that turns the Linux kernel into a hypervisor. The key differences are in how they work and the types of features and use cases they support. Both are full virtualization solutions and open source. "Free" is the top reason why over 357 developers like VirtualBox, while over 6 developers mention "Strong host isolation" as the leading cause for choosing VMware vSphere.Īccording to the StackShare community, VirtualBox has a broader approval, being mentioned in 724 company stacks & 975 developers stacks compared to VMware vSphere, which is listed in 56 company stacks and 24 developer stacks.Kernel-based Virtual Machine (KVM) and Oracle VM VirtualBox are Linux-based virtualization solutions that allow users to run various operating systems without “bare-metal” hardware. On the other hand, VMware vSphere provides the following key features: ![]() Guest Additions: shared folders, seamless windows, 3D virtualization.Some of the features offered by VirtualBox are: VirtualBox and VMware vSphere belong to "Virtualization Platform" category of the tech stack. Run fewer servers and reduce capital and operating costs using VMware vSphere to build a cloud computing infrastructure. vSphere is the world’s leading server virtualization platform. What is VMware vSphere? Free bare-metal hypervisor that virtualizes servers so you can consolidate your applications on less hardware. 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. ![]() ![]() VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. What is VirtualBox? Run nearly any operating system on a single machine and to freely switch between OS instances running simultaneously. VirtualBox vs VMware vSphere: What are the differences? ![]()
