linux - VirtualBox环境使用fuel部署openstack

我的环境：
部署硬件：windows 7 (8GB RAMCPU I5)+ virtualbox 5.1.4
部署工具：Mirantis Fuel 6.0，openstack juno
部署网络：

     1、10.20.0.0：这是master的专有网络，我们访问web的时候就是走这个网络；
     2、172.16.0.0：这是公共网络，也是浮动IP网段，给虚机提供外网
     3、192.168.4.0：这是openstack的管理、存储和虚机内部网络

前面步骤一切正常，最后起了一个controller节点和一个compute节点，给这两个节点安装操作系统后，界面报错了，如下图

红色文字信息如下：

用fuel部署openstack好几天了，一直没有成功，哪位大侠帮帮忙，谢谢
