ovirt是RHEV的社区版，是一个免费开源的虚拟化软件。它包括管理端和node节点，类似于vsphere和esxi大关系一样。Ovirt中集成了glusterfs分布式存储的管理功能，在图形化界面下友好的管理了glusterfs。下面大概看看它的组成部分：
一个 Ovirt环境包括：
1、主机（host）：基于 KVM 的、用来运行虚拟机的主机。在本文档中有时也被称为虚拟主机。
代理和工具程序：运行在主机上的代理和工具程序（包括 VDSM、QEMU 和 libvirt）。这些工具程序提供了对虚拟机、网络和存储进行本地管理的功能。
2、ovirt manager：一个对 CecOSvt 环境进行中央管理的图形界面平台。用户可以使用它查看、增添和管理资源。
3、存储域：用来存储虚拟资源（如虚拟机、模版和 ISO 文件）。
4、数据库：用来跟踪记录整个环境的变化和状态。/5、目录服务器：用来提供用户账户以及相关的用户验证功能的外部目录服务器。
5、网络：用来把整个环境联系在一起。它包括物理网络连接和逻辑网络。
搭建Ovirt 管理的ovirt-engine
本次系统环境为centos6.5，由于本次只是搭建管理端，并没有采用"all in one"的部署方式，所以我们本次的环境就仅仅有一台服务器。
将所有主机配置好DNS服务器或者将所有主机的主机名写入/etc/hosts中

可以看到已经安装成功了。使用浏览器输入https://192.168.2.100 输入账户密码就可以进入管理界面，一睹我们的管理平台了。
