在RHEV3.3平台建立一个新的数据中心后，发现不能重复使用默认的ISO_DOMAIN，需要重新建立一个ISO存储域。通过了解相关文档，方法如下：首先登陆RHEVM管理机服务器，在home目录下新建ISO文件夹，并将该文件夹共享：

执行命令如下：

[root@localhost iso]# cd /home/
[root@localhost home]# ls
exp  lost+found  nfs_rhev
[root@localhost home]# mkdir ISO
[root@localhost home]# chmod 777 ISO/
[root@localhost home]# ls
exp  ISO  lost+found  nfs_rhev
[root@localhost home]# vi /etc/exports
[root@localhost home]#
[root@localhost home]#
[root@localhost home]# exportfs -r
[root@localhost home]# exportfs
/var/lib/exports/iso0.0.0.0/0.0.0.0
/home/nfs_rhev  0.0.0.0/0.0.0.0
/home/exp       0.0.0.0/0.0.0.0
/home/ISO       0.0.0.0/0.0.0.0

执行完毕后登陆管理平台，在平台中新建存储域：

添加完成后激活该ISO存储域，添加成功：

添加默认的驱动程序：在RHEVM上执行如下命令：

[root@localhost home]# engine-iso-uploader --iso-domain=ISO_DOMAIN_HB upload /usr/share/virtio-win/virtio-win.iso /usr/share/virtio-win/virtio-win_x86.vfd /usr/share/virtio-win/virtio-win_amd64.vfd /usr/share/rhev-guest-tools-iso/rhev-tools-setup.iso
Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort):
Uploading, please wait...
INFO: Start uploading /usr/share/virtio-win/virtio-win.iso

INFO: Start uploading /usr/share/rhev-guest-tools-iso/rhev-tools-setup.iso
INFO: /usr/share/rhev-guest-tools-iso/rhev-tools-setup.iso uploaded successfully

添加成功后，新建主机即可发现已经加载了相关驱动程序，如下图：
