What is Xen Project?
The Xen Project is a free and open-source virtual machine monitor (VMM) that allows for the creation and management of virtual machines (VMs). 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 for the VMs.
Main Benefits
The Xen Project provides several benefits, including:
- Hardware Virtualization: Xen Project allows multiple VMs to run on a single physical machine, each with its own operating system and applications.
- High Performance: Xen Project’s type-1 hypervisor architecture provides direct access to hardware resources, resulting in high performance and low overhead.
- Security and Isolation: Xen Project provides a high level of security and isolation between VMs, making it suitable for use in environments where security is a top priority.
