#The best virtual machine software software#

Top opensource virtualization software for Linux 1. The hypervisor assigns each VM a portion of the underlying computing resources like memory and storage, thus preventing them from interfering. The hypervisor is a thin software layer that allows multiple operating systems to share physical computing resources and run alongside each other. However, you can use a hypervisor (a lightweight software layer) to manage the physical hardware. A virtual machine can’t interact directly with a physical computer. You can create multiple virtual machines, each with an operating system and applications on a single physical device. Virtual machineĪ virtual machine (VM) is a virtual representation of a physical computer. In essence, the main advantage of virtualization is that it’s a more efficient use of physical computer hardware. It allows a user or a business to run multiple virtual computers and operating systems on a single physical server.

Virtualization creates an abstraction layer over the physical hardware to create a virtual computing system, known as virtual machines (VMs).

The article will highlight several open-source virtualization software like Oracle VM VirtualBox, Linux-KVM, Redhat virtualization, Microsoft Hyper-V, Xen Project, oVirt, and boxes in Fedora. The Linux community has created several virtualization tools or Virt tools like QEMU, KVM, Libvert, or libguestfs which act as the basis for creating open-source virtualization software.
