KVM部署Alibaba Cloud Linux操作系统

下载镜像文件

下载链接：https://mirrors.aliyun.com/alinux/image/?spm=a2c4g.11186623.0.0.79ed5af6pehv54
下载文件：aliyun_3_x64_20G_nocloud_alibase_20230727.qcow2

部署KVM虚拟化环境

yum -y install qemu libvirt rr-testsuite
systemctl start libvirtd
systemctl enable libvirtd

准备镜像文件

将aliyun_3_x64_20G_nocloud_alibase_20230727.qcow2拷贝到镜像文件目录，一般默认/var/lib/libvirt/images/disks/

本地生成seed.img引导镜像

1、在镜像文件同一级目录下，创建meta-data和user-data两个配置文件。

cd /var/lib/libvirt/images/disks/
mkdir seed
cd seed
vi meta-data

#cloud-config
#vim:syntax=yamllocal-hostname: alinux-host

vi user-data

#cloud-config
#vim:syntax=yaml# 添加一个名为alinux的账号，并且可以执行sudo命令。
users:- default- name: alinuxsudo: ['ALL=(ALL)   ALL']plain_text_passwd: aliyunlock_passwd: false# 添加Alibaba Cloud Linux 3的YUM源。

2、配置epel-testing仓库

vi /etc/yum.repos.d/epel-testing.repo

[epel-testing]
name=Extra Packages for Enterprise Linux 8 - Testing - $basearch
baseurl=http://mirrors.cloud.aliyuncs.com/epel/testing/8/Everything/$basearch
enabled=0
gpgcheck=1
countme=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8

3、安装cloud-utils并生成seed.img镜像

sudo yum install -y cloud-utils
sudo cloud-localds seed.img user-data meta-data

定义虚拟机

vi /etc/libvirt/qemu/AliyunOS3.xml
