摘要

Minix是一个开源的多服务器操作系统,设计为高度可靠、灵活和安全。内核很小,是唯一在特权模式下运行的软件,另一方面,用户进程、专用服务器和设备驱动程序作为独立的进程在用户模式下运行。系统调用使用进程间通信原语向服务器发送请求服务的消息,并等待响应消息。本文中描述的项目的目标是在基于中间件的虚拟机上运行一个用户空间的多服务器操作系统(修改后的Minix版本),该虚拟机具有由主机操作系统(Linux)提供的服务构建的模拟硬件。

Minix over Linux: A User-Space Multiserver Operating System
Minix is an open-source multiserver operating system designed to be highly reliable, flexible, and secure. The kernel is small and is the only piece of software that runs in privileged-mode, on the other hand user processes, specialized servers and device drivers run as isolated processes in user-mode. System Calls use Interprocess Communications primitives to send messages requesting services from the servers, and to wait for response messages. The aim of the project described in this article is a user-space multiserver operating system (a modified Minix version) running on top of a middleware-based virtual machine with simulated hardware constructed from services provided by a host operating system (Linux).
