What is Xen Project?
Xen Project is a free and 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 an underlying operating system. This provides a high level of performance, security, and isolation for each VM.
