What is Xen Project?
The Xen Project is an open-source virtualization platform that enables users to run multiple virtual machines (VMs) on a single physical host. It is a type-1 hypervisor, which means it runs directly on the host machine’s hardware, providing a layer of abstraction between the operating system and the hardware. The Xen Project is widely used in cloud computing, virtualization, and containerization due to its high performance, scalability, and security features.
