What is Xen Project?
Xen Project is an open-source virtualization platform that enables the creation and management of virtual machines (VMs) and containers. It is a hypervisor that runs directly on the host machine’s hardware, allowing multiple guest operating systems to run simultaneously. The Xen Project is widely used in cloud computing, server virtualization, and embedded systems.
History of Xen Project
The Xen Project was first released in 2003 by the University of Cambridge. It was later acquired by Citrix Systems in 2007 and became an open-source project in 2013. Today, the Xen Project is maintained by the Linux Foundation and has a large community of contributors.
Key Features of Xen Project
Virtualization
