服务器评测
说一下我的网络拓扑结构，
192.168.3.1 是RHEV-M端，系统是RHEL6.2 x86_64，并且兼职DNS服务器和存储的服务端
192.168.3.101 是RHEV-H端，系统是RHEV hypervisor 6.2 beta版本
192.168.3.201 是浏览器端，安装的是Windows XP，浏览器是IE 8

由于我只有两台机器，其中RHEV-H端还必须安装在真机上，所以，我只能吧RHEV-M和Windows XP这两个操作系统安装到虚拟机里面了。
其中，我的RHEV-H的真机是16G的内存，我在另外一台机器上给RHEV-M分了4G 内存，Windows XP分了512M内存。
红帽的官方的最低要求是：
RHEV-M：最低4G内存，25G的磁盘可用空间，千兆网卡
（推荐是 双路/四核的CPU，16G内存，50G的可用磁盘，千兆网卡）
RHEV-H：最低是双核的CPU，10G内存，10G的存储，千兆网卡
（推荐是双路的CPU，16G内存，50G的存储，两块千兆网卡）
浏览器端：操作系统是Windows （XP，2003，Vista，7,2008），浏览器的版本必须是IE 7.0以上版本（包含IE 7.0），并且要安装Microsoft .NET Framework 4（下载地址是http://www.microsoft.com/download/en/details.aspx?id=17718）
安装RHEV-M
如果你注册了红帽的RHN，并且订阅了RHEVM相关的频道，你只需要敲一条命令即可：
yum -y install rhevm
我这里已经将所有的依赖包都做成了一个ISO文件，下载地址见上一篇博客，安装的
时候，只需要将这个ISO镜像拷进系统里面，mount到一个目录，然后sh目录中的
install.sh这个脚本即可。
mount -o loop rhevm-for-rhel6.2.iso 任意目录，然后sh 目录中的install.sh
这个ISO镜像适合RHEL6.2及其衍生版本，比如CentOS 6.2 Scientific Linux 6.2
等，我测试过CentOS 6.2没什么问题。
执行完脚本之后，执行rhevm-setup这个命令来进行安装配置：
我的安装过程如下。
[root@rhevm named]# rhevm-setup
Welcome to RHEV Manager setup utility
HTTP Port [8080] :
HTTPS Port [8443] :
Host fully qualified domain name, note that this name should be fully resolvable [rhevm.linuxidc.com] :
Password for Administrator (admin@internal) :
Warning: Weak Password.
Confirm password :
Database password (required for secure authentication with the locally created database) :
Warning: Weak Password.
Confirm password :
Organization Name for the Certificate: linuxidc-lab
The default storage type you will be using [‘NFS’| ‘FC’| ‘ISCSI’] [NFS] : ISCSI
Should the installer configure NFS share on this server to be used as an ISO Domain? [‘yes’| ‘no’] [yes] : yes
Mount point path: /var/iso
Display name for the ISO Domain: linuxidc-iso
Firewall ports need to be opened.
You can let the installer configure iptables automatically overriding the current configuration. The old configuration will be backed up.
Alternately you can configure the firewall later using an example iptables file found under /usr/share/rhevm/conf/iptables.example
Configure iptables ? [‘yes’| ‘no’]: yes
RHEV Manager will be installed using the following configuration:
=================================================================
http-port: 8080

* To configure additional users, first configure authentication domains using the ‘rhevm-manage-domains’ utility
* To access RHEV Manager please go to the following URL: http://rhevm.linuxidc.com:8080
解释一下安装过程，首先是提示相关的端口，然后是主机名，管理员登陆的密码，数据库的密码，存储的类型，我这里选择的是iSCSI，然后又设置了NFS来存储系统的安装镜像。
最后系统生成了SSH和SSL的信息。
最后是提示你，可以通过http://rhevm.linuxidc.com:8080这个路径来访问。
