解决RHEV上传安装源（ engine-iso-uploader）异常出错问题解决方案

在rhev3.4红帽虚拟化平台中，遇到上传安装源异常出错的问题，提示错误信息为“'NoneType' object is not iterable”，具体如下：
[root@rhevm ]# engine-iso-uploader --iso-domain=ISO_DOMAIN -v upload rhev-hypervisor6-6.5-20140407.0.iso

Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort):
ERROR: Problem connecting to the REST API. Is the service available and does the CA certificate exist?
ERROR: 'NoneType' object is not iterable
INFO: Use the -h option to see usage.
DEBUG: Configuration:

官方给出的解决方案有四种，分别如下：









但尝试了以上的解决方案都没有解决，最终提供一种最简单的方法：直接将安装源ISO文件复制到对应目录，目录为：
/path-to-iso-domain/SOME-UUID/images/11111111-1111-1111-1111-111111111111/

如：

[root@rhevm 11111111-1111-1111-1111-111111111111]# cd /home/ISO_DOMAIN/d75fefad-a4ce-4528-8055-450a98e1dd5e/images/11111111-1111-1111-1111-111111111111/
[root@rhevm 11111111-1111-1111-1111-111111111111]# ls
cn_windows_server_2012_vl_x64_dvd_917962.iso virtio-win_amd64.vfd
rhev-hypervisor6-6.5-20140407.0.iso virtio-win.iso
rhev-tools-setup.iso virtio-win_x86.vfd
virtio-win-1.7.1.iso
[root@rhevm 11111111-1111-1111-1111-111111111111]# cp rhev-tools-setup.iso /home/ISO_DOMAIN/d75fefad-a4ce-4528-8055-450a98e1dd5e/images/11111111-1111-1111-1111-111111111111
直接上传后，更新存储域：ISO_DOMAIN，可发现已经将ISO安装源成功上传到RHEV平台中：



在虚拟机运行选项中也可以发现上传的安装源：
