xEN

xEN refers to a virtualization technology that allows multiple operating systems to run on a single physical machine. It is an open-source hypervisor that supports paravirtualization and hardware-assisted virtualization. xEN enables efficient resource management and operational flexibility by abstracting the underlying hardware and providing isolated environments (domains) for guest operating systems. This allows for better utilization of server resources, as multiple guests can be run concurrently without significant performance degradation. xEN is known for its stability and scalability, making it suitable for enterprise environments and cloud computing services. The technology typically includes tools for managing virtual machines, such as starting, stopping, and configuring guests, and it is commonly used in data centers for server consolidation and increasing workload efficiency.
