篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了qemu制作CentOS 7虚拟机镜像文件相关的知识,希望对你有一定的参考价值。

参考技术A

如果是vm虚拟机,记得开启cpu的虚拟化功能

笔者的环境是CentOS 7.3 1611

想要强制指定虚拟网卡的名称eth0,安装完系统重启后进行一下配置

启动虚拟机

安装Qemu-6.1.0

安装Qemu

1. yum安装

TODO
CentOS8使用yum安装的qemu版本为4.2.0,如果需要最新版本,需要从https://www.qemu.org/download/下载最新源码,编译安装。

2. 源码安装

2.1. 下载

Qemu最新源码下载链接:https://www.qemu.org/download/

CentOS8使用yum安装的qemu版本为4.2.0,如果需要最新版本,需要从https://www.qemu.org/download/下载最新源码,编译安装。

2.2. 编译

wget https://download.qemu.org/qemu-6.1.0.tar.xz
tar xvJf qemu-6.1.0.tar.xz
cd qemu-6.1.0
./configure
make

如果使用GitLab上的master分支,可以:

git clone https://gitlab.com/qemu-project/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
make

当执行./configure会产生如下错误:

[rongtao@bogon qemu-6.1.0]$ ./configure 
Using './build' as the directory for build output

ERROR: Cannot find Ninja

为了确保体系结构、KVM支持、调试功能,可以在配置阶段指令选项:

./configure '--target-list=x86_64-softmmu' '--enable-kvm' '--enable-debug'

安装Ninja见附录。安装Ninja之后,再次./configure,提示仍旧有错误:

$ ./configure

我们一个一个看。为了清晰,给出截图:

安装pixman即可,参见附录。接着再次./configure,即可成功。然后进行编译:

安装成功。

4. 附录

4.1. 安装Ninja

参考链接:How to Install Invoice Ninja on CentOS 7

Ninja下载:RPM包

这里使用RPM包安装,但是安装过程会提示需要Python2.7,正如centos.pkgs.org所说,ninja的依赖为:

emacs-filesystem	-
libc.so.6(GLIBC_2.15)(64bit)	-
libgcc_s.so.1()(64bit)	-
libgcc_s.so.1(GCC_3.0)(64bit)	-
libm.so.6()(64bit)	-
libstdc++.so.6()(64bit)	-
libstdc++.so.6(CXXABI_1.3)(64bit)	-
libstdc++.so.6(GLIBCXX_3.4)(64bit)	-
python(abi)	= 2.7
rtld(GNU_HASH)	-
vim-filesystem	-

直接使用yum安装python2.7就可以了:

$ sudo yum install python2

然后再次安装ninja:

$ sudo rpm -i ninja-build-1.10.2-3.el7.x86_64.rpm

成功。

4.2. 安装pixman

很简单

$ sudo yum install -y pixman pixman-devel
