QEMU零知识学习3 —— QEMU配置

本文接前一篇文章《QEMU零知识学习2 —— QEMU源码下载》，链接如下：

QEMU零知识学习2 —— QEMU源码下载_蓝天居士的博客-CSDN博客

基于第2种方式通过wget下载源码压缩包解压后生成的源码进行QEMU的配置。

配置QEMU

QEMU的配置并不复杂，直接运行源码根目录下的configure进行配置即可。

（1）查看配置帮助信息

如果对QEMU的配置不熟悉，可以运行以下命令查看配置的选项及其帮助信息：

$ ./configure --help

在以上configure选项中，特别提一下“--target-list”，其指定QEMU对客户机架构的支持。可以看到，对应的选项相当多，从表面上来看，QEMU对客户机的支持非常全面。

加上“--target-list=x86_64-softmmu代表”只使用x86架构的客户机，在编译时可以节省大量的编译时间。

在配置完成以后，QEMU源码根目录的build文件夹下会生成config-host.mak和config.status文件。

config-host.mak文件中可以查看执行configure后的结果，它会在后续make编译时被引用。不带“--target-list=x86_64-softmmu”选项时其内容如下：
