在研究桌面云的过程中，发现对于真正落地来说，服务端（私有云或者虚拟化）没有太多的区别，更多的是瘦客户端的使用和对桌面的管理方面有诸多需要考虑的地方，最终落地可能都是需要定制化开发才能很好的满足需求。
在开源虚拟化产品中，限于自己的经验和眼界，Ovirt原来一直没有接触，在和朋友的沟通过程中，发现Ovirt对于桌面云解决方案更接地气，更具有项目落地的优势。
这里记录一下第一次安装oVirt测试环境熟悉过程。
Ovirt官网安装参考：
https://ovirt.org/documentation/install-guide/Installation_Guide.html
安装前准备：
下载CentOs7.8和Ovirt-node 安装镜像：
CentOS-7-x86_64-DVD-1908
ovirt-node-ng-installer-4.3.6-2019092614.el7
oVirt-engine官网安装文档：
https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html
在自己的PVE测试环境中创建2个虚拟机安装centos7.8 ，一个安装ovirt引擎，一个安装宿主机host。
编辑 /etc/hosts文件：
192.168.170.110 ovirt-manager.yuweibing.com ovirt-engine
192.168.170.114 ovirt-host1.yuweibing.com ovirt-host1
配置IP地址（略）
修改主机名（略）
根据上面oVirt-engine官网安装文档逐步进行安装，其中，执行下面命令：
# yum install ovirt-engine
的时候花了很长时间，主要是下载包的时间花了较多的时间，网络速度很慢，大概10k-20k左右甚至更低，400M的包花了几个小时下载完。
之后，需要配置ovirt-engine
对postgresql数据库不熟悉，随便参考网上新手教程：

安装成功。需要使用域名访问web管理网页：
编辑本机的 c:\windows\system32\drivers\etc\hosts文件，增加：
192.168.170.110 ovirt-manager.yuweibing.com ovirt-engine
192.168.170.114 ovirt-host1.yuweibing.com ovirt-host1
