参考: ovirt一种基于kvm的开源虚拟化软件
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 node11.2 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
- Vorit engine安装
- 安装计算节点
- 存储部署（此文档用的是NFS存储）
- spice客户端安装
- 创建虚拟机
- 网络配置
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.rpm2). 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)

If you choose to not configure it on this host, you have to configure
it on a remote host, and then configure the engine on this host so
that it can access the database of the remote Data Warehouse host.

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 restart2.4 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 libvirtd2.5.2 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
3.3 镜像拷贝
3.3.1 拷贝镜像
把系统的镜像拷贝到node1节点的以下路径：
/iso/2eb33fb7-ecae-490a-9463-15016a6c41fb/images/11111111-1111-1111-1111-111111111111
3.3.2 上传镜像文件
进行完上述操作，成功添加存储域后，查看node43的data目录，发现已经更新下级的文件夹
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。
五、创建虚拟机
5.1 新建虚拟机配置
5.2 添加虚拟磁盘
点击新建实例镜像
编辑虚拟机配置，该项比较重要，不然会没法引导
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
