What is Xen Project?
Xen Project is an open-source virtualization platform that allows users to run multiple virtual machines (VMs) on a single physical host. It is a type-1 hypervisor, also known as a bare-metal hypervisor, which means it runs directly on the host machine’s hardware without the need for a host operating system. Xen Project is widely used in cloud computing, virtual private servers, and other applications where multiple VMs need to be run on a single physical host.
