ERIKA3 on the Xen hypervisor

Introduction

Xen is an open-source type-1 or baremetal hypervisor.

Xen runs directly on the hardware and is responsible for handling CPU, memory, timers and interrupts. The hypervisor is started by the boot loader and, once it is loaded, it starts the privileged domain Dom0 (short for "domain 0") containing the drivers of the system devices. Once Dom0 has started, one or more user domains, referred to as DomU, can be started and controlled in the Dom0. Xen supports both para-virtualized (PV) and fully hardware virtualized (HVM) user domains.

This tutorial will explain how to build and run ERIKA3 as Xen hardware-virtualized DomU on the x86-64 platform.
