QEMU简单使用的笔记

安装

apt update && apt install qemu

启动

支持的架构真的多

很多时候已经有现成的镜像和内核了

比如debian就提供了比较多

https://people.debian.org/~aurel32/qemu/

而且里面也给了启动方式，至于内核，32还是64什么的就自己选了

- qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1"
- qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.32-5-versatile -initrd initrd.img-2.6.32-5-versatile -hda debian_squeeze_armel_desktop.qcow2 -append "root=/dev/sda1"
- qemu-system-arm -M versatilepb -kernel vmlinuz-3.2.0-4-versatile -initrd initrd.img-3.2.0-4-versatile -hda debian_wheezy_armel_standard.qcow2 -append "root=/dev/sda1"
- qemu-system-arm -M versatilepb -kernel vmlinuz-3.2.0-4-versatile -initrd initrd.img-3.2.0-4-versatile -hda debian_wheezy_armel_desktop.qcow2 -append "root=/dev/sda1"

当然这里还有一些装好gdb和gef的镜像

https://blahcat.github.io/2017/06/25/qemu-images-to-play-with/

还要说的就是端口的映射，可以在上面指令的基础上加上下面这个

-redir tcp:22::22

不要图像界面可以下面这样，直接给完整示例吧

qemu-system-arm -M versatilepb -kernel vmlinuz-3.2.0-4-versatile -initrd initrd.img-3.2.0-4-versatile -hda debian_wheezy_armel_standard.qcow2 -append "root=/dev/sda1" -redir tcp:22::22 -redir tcp:10000::10000 -redir tcp:10001::10001 -redir tcp:10002::10002 -redir tcp:1616::1616 -nographic

退出当前虚拟机

ctrl + A 再按 X
