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. Both are full virtualization solutions and open source. The key differences are in how they work and the types of features and use cases they support. Show
What Is KVM?KVM, also known as the KVM hypervisor, is a virtualization module that turns the Linux kernel into a hypervisor. 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. 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. Advantages of KVMA 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. The primary advantages of KVM are:
What Is VirtualBox?Developed by Oracle, VirtualBox is an open source virtualization software that is a type 2 hypervisor. That means it runs on a conventional OS just as other computer programs do and abstracts guest operating systems from the host OS. Type 2 hypervisors like VirtualBox are sometimes called “hosted” hypervisors because they rely on the host machine’s pre-existing OS to manage calls to CPU, memory, storage, and network resources. VirtualBox supports the following guest operating systems:
Advantages of VirtualBoxVirtualBox offers many features that should be attractive to IT and development professionals:
To summarize, VirtualBox provides a high-performance environment to have multiple operating systems living under a single hood (i.e., one computer). This allows you to easily develop and test your applications and see how they would run on Windows, Mac, Linux, Oracle Solaris, or any other machine. KVM and VirtualBox are both powerful virtualization solutions that cost nothing out of the box and have robust community support. The best one to use will depend on your needs. KVM, a type 1 hypervisor, is smaller and faster than VirtualBox, but VirtualBox is more scalable. KVM is better integrated with Linux, and while it will work with other guests, it works best with Linux. In short, if you want to install a binary Linux distribution as a guest, it’s better to use KVM. But if your guest involves lots of compiling and requires more advanced features, or if it isn’t a Linux system, VirtualBox would be a better choice. Make the Most of Your Virtualization Software with FlashArray//XVirtualization software has proven to dramatically increase IT efficiency and flexibility. However, most IT departments are unable to take full advantage of their virtualization investments because their data storage systems aren’t updated and are creating massive bottlenecks in their virtual environments. Pure Storage® FlashArray//X, the latest generation of all-flash enterprise block storage, allows companies to optimize their virtualized environments with flexible, scalable data storage that enables the virtualization of everything, even performance-hungry mission-critical workloads such as large databases. The 100% NVMe FlashArray//X is designed to accelerate and consolidate all your apps—both mainstream enterprise and next-gen web-scale—delivering up to 3PB effective storage in 6U. Not only can you virtualize every workload, but common management tasks are also simpler and faster, reducing the burden on IT administrators. Learn more about FlashArray//X. Which virtualization platform runs on top of Windows Linux and macOS?VMware Fusion
It's best for corporate and enterprise-level systems thanks to its advanced management systems and because its virtual machines can run on macOS, Windows, and Linux.
What is VirtualBox in Linux?VirtualBox is open-source software for virtualizing the x86 computing architecture. It acts as a hypervisor, creating a VM (virtual machine) where the user can run another OS (operating system). The operating system where VirtualBox runs is called the "host" OS.
Which software is used for virtualization?VMware Fusion, Parallels Desktop, Oracle VM Virtual Box and VMware Workstation are the top four software that is really good for virtualization. Oracle VM Virtual Box gives you really nice features at a free of cost. It can also be used on Mac, Windows, Linux, and Solaris.
Which is better VMware or VirtualBox?If you already work in a VMware environment, Workstation/Fusion is clearly the better option, as it has better compatibility with VMware servers and data management tools. Overall, it's probably a superior option for business use. Virtual machines created by VMware are faster than those created by VirtualBox.
