通过官方仓库安装

官方文档：https://www.qemu.org/download/#linux

Ubuntu

容易安装，但是版本有可能更新不及时：

sudo apt-get install qemu

通过源码编译安装

官方文档：https://www.qemu.org/download/#source

安装步骤

首选下载源码

官方地址太慢了，这里去清华镜像源 https://mirror.tuna.tsinghua.edu.cn/help/qemu.git/ 下载源码

git clone https://mirrors.tuna.tsinghua.edu.cn/git/qemu.git

然后编译安装

$ cd qemu/
$ ./configure
$ make

RISC-V 相关

官方文档：https://wiki.qemu.org/Documentation/Platforms/RISCV

这里如果想用 QEMU 模拟其他平台，可以在配置时指定，例如对于 RV64：

 ./configure --target-list=riscv64-softmmu && make

对于 RV32：

 ./configure --target-list=riscv32-softmmu && make

常见报错及处理
