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 a host operating system. This provides a high level of performance, security, and isolation between VMs.
Main Features of Xen Project
Xen Project provides a range of features that make it an attractive solution for virtualization and containerization. Some of the key features include:
- Support for multiple VMs on a single host
- High-performance and low overhead
- Secure and isolated environments for each VM
- Live migration and snapshots for easy backup and recovery
- Support for a wide range of guest operating systems
