Introduction
Xen is a free and open source type-1 hypervisor. The Xen hypervisor is developed as a Linux Foundation project as part of the Xen Project.
On AMD-Xilinx devices, Xen runs as part of Arm execution-level 2 (EL2). Xen hypervisor consists of three components:
- Xen Core - the central management engine of the Xen hypervisor
- Xen Domain 0 (Dom0) - the primary control domain. This domain hosts Xen utilities used to manage the lifecycle of User Domains
- One or more User Domains (DomU) - the various user/application domains. These domains run user applications and operating systems.
