ACRN超级管理器介绍
|
||||
==================
|
||||
|
||||
ACRN超级管理器是一个第一类超级管理器,直接在裸机硬件上运行。它有一个特权管理虚拟机,称为服
|
||||
务虚拟机,用于管理用户虚拟机和进行I/O仿真。
|
||||
|
||||
ACRN用户空间是一个运行在服务虚拟机中的应用程序,它根据命令行配置为用户虚拟机仿真设备。
|
||||
ACRN管理程序服务模块(HSM)是服务虚拟机中的一个内核模块,为ACRN用户空间提供管理程序服
|
||||
务。
|
||||
|
||||
下图展示了该架构。

|
||||
|
||||
ACRN用户空间为用户虚拟机分配内存,配置和初始化用户虚拟机使用的设备,加载虚拟引导程序,
|
||||
初始化虚拟CPU状态,处理来自用户虚拟机的I/O请求访问。它使用ioctls来与HSM通信。HSM通过
|
||||
与ACRN超级管理器的hypercalls进行交互来实现管理服务。HSM向用户空间输出一个char设备接口
|
||||
(/dev/acrn_hsm)。
|
||||
|
||||
ACRN超级管理器是开源的,任何人都可以贡献。源码库在
