Introduction to Top Open Source Virtualization Tools

Ganeti

Ganeti is a cluster server management tool developed by Google; it is built on existing virtualization technologies like KVM, Xen and other Open Source software

KVM (Kernel-based Virtual Machine)

KVM is an open source virtualization tool for Linux and contains virtualization extensions (AMD-V or Intel VT). It can either be operated in emulation or hardware mode;

oVirt

oVirt is a virtualization solution used to manage/create virtual datacenters. oVirt manages storage options, virtualized networks, and virtual machines using interactive an easy to use web-based administration and user portal

Packer

Packer can be used by system admins to build then subsequently manage the operations of virtual machine images. The same commands and files can be used to build an image on Digital Ocean, AWS or for vagrant and VirtualBox.

Vagrant

Vagrant is a command-line tool that provides a framework and configuration format for creating, managing and distributing virtualized development environments.

VirtualBox

VirtualBox is an open source cross-platform product that is currently under the stewardship of Oracle. VirtualBox is one of the veterans of the virtualization scene, and remains a lightweight and reliable virtualization tool that is easy to install and use.

Xen

Xen is a hypervisor that started out as a Microsoft backed startup at the University of Cambridge and has now risen to become one of the best Linux hypervisors. The Xen Hypervisor is inserted between the server’s hardware and the operating system. This creates an abstraction layer that allows multiple guest operating systems to be concurrently executed on a single physical server. Xen is included with most popular Linux distributions like Fedora, RHEL, CentOS, Ubuntu, and Debian.
