标签：x86 自定义 python QCOW2 noarch 64 OpenStack el7 2.5
一、安装KVM虚拟机
1.1 虚拟机安装虚拟化软件包
注意：虚拟机指的是CentOS7.8
#挂载光盘
[root@cloudcs ~]# mount /dev/cdrom /mnt
mount: /dev/sr0 is write-protected, mounting read-only
[root@cloudcs ~]# ls /mnt/
CentOS_BuildTag EULA images LiveOS repodata RPM-GPG-KEY-CentOS-Testing-7
EFI GPL isolinux Packages RPM-GPG-KEY-CentOS-7 TRANS.TBL
#配置本地YUM源
[root@cloudcs ~]# mkdir /tmp/repo
[root@cloudcs ~]# mv /etc/yum.repos.d/*.repo /tmp/repo/
[root@cloudcs ~]# vim /etc/yum.repos.d/local.repo
[root@cloudcs ~]# cat /etc/yum.repos.d/local.repo
[local_repo]
name = local
baseurl = file:///mnt/
gpgcheck = 0
#安装虚拟化软件包及虚拟机镜像管理工具
[root@cloudcs ~]# yum groupinstall -y "Virtualization*"
[root@cloudcs ~]# yum install -y libguestfs-tools-c.x86_64
1.2 创建KVM虚拟机
注意：虚拟机通过命令ifconfig可看到一张虚拟网卡vritbr0，该虚拟网卡为kvm虚拟机default默认的NAT网络类型网卡（192.168.122.1）
#创建目录上传ISO镜像
[root@cloudcs ~]# mkdir -p /soft/disk
#将CentOS7.4上传到 /soft 目录下
[root@cloudcs ~]# ls /soft/
CentOS-7-x86_64-DVD-1708.iso disk
#创建kvm虚拟机使用的磁盘文件
[root@cloudcs ~]# qemu-img create -f qcow2 /soft/disk/centos7.qcow2 15G
Formatting '/soft/disk/centos7.qcow2', fmt=qcow2 size=16106127360 encryption=off cluster_size=65536 lazy_refcounts=off
#创建kvm虚拟机
virt-install \
--name centos \
--disk path=/soft/disk/centos7.qcow2 \
--vcpus 1 \
--memory 2048 \
--location /soft/CentOS-7-x86_64-DVD-1708.iso \
--network network=default
1.3 安装KVM虚拟机
1.3.1 语言选择
1.3.2 自动分区
1.3.3 网络及主机名
注意：当开启网络后，必须可以通过 DHCP 自动获取到 IP 地址，如下图
1.3.4 配置 ROOT 密码
默认采用最小化 minimal 安装
1.3.5 重启并测试网络
重启kvm虚拟机，并以root身份登录，测试kvm虚拟机 能否连通外网
二、配置 KVM 虚拟机
2.1 修改KVM虚拟机网络配置文件
注意：修改的是kvm虚拟机，不是虚拟机，概念分不清？参考第一部分 约定
# 修改 kvm 虚机网卡配置文件，使其只包括以下 4 行内容
[root@local ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@local ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=dhcp
DEVICE=eth0
ONBOOT=yes
2.2 安装 cloud-init 软件包
根据 1.3.5 小节测试，kvm 虚机可正常连通外网，此时直接在线安装软件包即可。目的是为了可以获取到客户自定义元数据信息，如主机名及root密码等。
[root@local ~]# yum install -y cloud-utils-growpart cloud-init

2.6 关闭 KVM 虚拟机
[root@local ~]# init 0
三、创建 QCOW2 镜像
注意：以下步骤在虚拟机中操作，不是kvm虚拟机，概念分不清？参考第一部分 约定
3.1 重置并清理镜像
[root@cloudcs ~]# virsh list --all

3.2 创建并压缩镜像
#查找 centos 实例对应的磁盘文件
[root@cloudcs ~]# virsh domblklist centos

vda /soft/disk/centos7.qcow2
hda -
#创建并清理压缩镜像
[root@cloudcs ~]# virt-sparsify --compress /soft/disk/centos7.qcow2 /tmp/centos-cloud.qcow2

四、测试镜像启动
4.1 注册镜像
将镜像 centos-cloud.qcow2 注册到 OpenStack 平台，以下为图形化注册演示，命令行注册请参考博文 G020-OP-INS-RHEL-02 RedHat OpenStack 发放云主机（命令行）
4.2 创建云主机类型（规格）
4.3 发放云主机测试
注意：网络及路由请参考 G020 创建，务必保证路由及网关存在，否则无法获取到客户自定义主机名
观察启动流程及尝试登录，测试镜像正确无误
