【MIT6.828】centos7下使用Qemu搭建xv6运行环境

1. 基础依赖

yum install libX11 libX11-devel SDL2 SDL2-devel -y

2. 编译和安装 QEMU

~]# wget https://download.qemu.org/qemu-4.2.0.tar.xz

~]# xz -d qemu-4.2.0.tar.xz && tar xf qemu-4.2.0.tar

~]# cd qemu-4.2.0/

~]# cat VERSION

~]# 4.2.0

~]# ./configure --help

~]# ./configure --prefix=/usr/local  \

--enable-kvm \

--enable-debug \

--enable-debug-info \

--enable-curl \

--enable-sdl   \

--enable-vhost-net  \

--enable-vnc   \

--enable-gtk \

--target-list=i386-softmmu

然后安装

make && make install

3. xv6运行

git clone https://github.com/yaoliu/xv6-public

cd xv6-public

make

运行方式

make qemu

或者使用make-gdb的方式运行

使用qemu-system-i386 -serial mon:stdio -hdb fs.img xv6.img -smp 1 -m 512

以上三种均可
