一、oVirt安装前准备
1.1 基本规划
ip地址 系统 主机名 192.168.1.1 centos7.6 oVirt-engine 192.168.1.2 centos7.6 node1
1.2 配置DNS
# vi /etc/resolv.conf nameserver=114.114.114.114 search localdomain
配完后可以ping www.baidu.com看是否配置成功
1.3 设置主机名
1.4 Ovrit部署虚拟机主要分为五部分
1.5 环境准备
主机名为node1的虚拟机需要在虚拟机上开启嵌套虚拟化，CentOS7是否支持虚拟化，参考：《http://在 Centos7 的KVM虚拟机上启用嵌套虚拟化》
二、Vorit-engine安装及配置
2.1 安装Vorit-engine
添加官方oVir存储库并安装ovirt-engine程序包和依赖包(由于软件源问题会非常慢)
1). 设置安装源
yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2). 安装 ovirt-engine
yum install ovirt-engine
2.2 配置oVirt-engine
ovirt-engine安装完成后需要运行首次配置向导，执行如下命令：
# engine-setup
(配置向导比较多，需要注意的地方红色标出,未标出的直接回车下一步)

具体配置截图如下：
2.3 修改oVirt-engine的web登陆方式（默认是以FQDN方式登陆）
[core@localhost ~]$ vi /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf # ovirt取消主机名解析 SSO_CALLBACK_PREFIX_CHECK=false
全部修改结果如下图：
修改完成后重启ovirt-engine服务：
# service ovirt-engine restart
2.4 浏览器访问
在windows浏览器中输入：https://ip/ovirt-engine
用户名：admin,密码为安装过程中设置的
点击“管理门户”
用户名admin
密码：上述安装过程输入的密码
2.5 安装计算节点
2.5.1 在计算节点机器，执行如下命令
# 1.设置安装源, 这里为官方oVir存储库 # yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm # 2.安装软件 # yum -y install qemu-kvm libvirt virt-install bridge-utils vdsm # yum install cockpit cockpit-ovirt-dashboard -y # 3.启动服务并设置开机启动 # systemctl start libvirtd # systemctl enable libvirtd
2.5.2 添加节点
在oVirt-engine界面上创建相应资源
输入节点的Ip地址和root密码
此处忽略电源管理
点击事件可以看到过程
节点正在安装过程
添加完成之后可以看到节点信息
三、创建虚拟机镜像
3.1 创建存储目录
在node1节点上面执行以下命令：
mkdir /images chown -R vdsm /images/ mkdir /iso chown -R vdsm /iso/
3.2 engine管理页面添加存储域
新建存储域
新建镜像域
创建成功
四、安装spice客户端
本文选用spice客户端来访问虚拟机，因此需要在使用windows的机子上安装一个virt-viewer（也就是官方推荐的remote-viewer客户端），官网直接下载即可，没什么技巧。使用linux的机子就更简单啦~直接yum install virt-viewer即可。
5.3 高级配置
点击左下角的高级选项，根据需要自己定义内存大小，控制台图形界面类型可以选择spice或者是vnc
记得选择引导序列，需要把CD附加勾选上
配置好之后，点击确定稍等30秒左右，虚拟机创建成功。
运行一次进行安装
5.5 调整引导顺序
点击确定会自动下载一个console.vv文件，在安装了remote-viewer的前提下，直接双击该文件即可打开虚拟机控制台。
六、网络配置
安装的时候选择桥接模式，linux装成功后，选择手动，正确配置ip,掩码，网关，DNS,可直接用控制台工具，在桌面设置
6.1 点击控制台-进入Linux桌面
6.2 编辑-配置网络
Linux安装完成后，在控制台选择部署好的虚拟机，编辑-配置网络
