一直跟着视频做，没有遇到错误。在下载镜像是出现错误：命令：wget -P /tmp/images http://cdn.download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img
错误：
正在连接 cdn.download.cirros-cloud.net (cdn.download.cirros-cloud.net)|173.205.6.209|:80... 已连接。
已发出 HTTP 请求，正在等待回应... 404 Not Found
2015-06-17 00:11:23 错误 404：Not Found。

解决方法：
1 核对命令没有写错
2 在浏览器上直接访问，结果是：The resource could not be found.
3 到官网查看：发现（ pdf和视频上的地址和官网上资源地址不同）
$ mkdir /tmp/images$ cd /tmp/images/$ wget http://download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-disk.img4 问题解决：已发出 HTTP 请求，正在等待回应... 200 OK

十分抱歉：后知后觉！没有往下面看就发布了！

在首次配置nova时遇到ERROR nova.virt.libvirt.driver [-] Connection to libvirt failed: no connection driver available for qemu:///system的问题无法解决，在第二次重新搭建后未遇到此类问题，估计是参数复制时出错了，错误截图如附件。
在创建虚拟机时两次出现错误而终止，第3次在重启openstack后成功部署。

根据老师视频上的操作，先后执行source admin-openrc.sh和source demo-openrc.sh，执行后报错
[root@localhost ~]# keystone user-list
You are not authorized to perform the requested action: admin_required (HTTP 403)
解决的办法是，只执行source admin-openrc.sh就可以了
是不是因为，admin用户前边已经分配权限了，而demo用户虽然创建了，但是却没设置权限呢
先不试了，就这样吧，要不进度跟不上了

这个我创建的网络，没有任何错误。
但是之后运行neutron net-create demo-net一直报错ervice Unavailable (HTTP 503) 这是/var/log/neutron/service.log中的错误信息：

就是这个错误：NoNetworkAvailable: Unable to create the network. No tenant network is available for allocation.

这个是我的neutron网络信息：可见ext-net是创建成功的

报错是因为服务队列没有起来
一般来说从启服务即可
systemctl restart rabbitmq-server
systemctl statusrabbitmq-server
systemctl status rabbitmq-server

systemctl status rabbitmq-server
systemctl start libvirtd.service openstack-nova-compute.service

当大家安装错了，如何进行下一步呢？像我一样，先御载后再继续安装就可以了，谢谢老师，深入浅出，起码有点步骤如配置如何代理上网等不用我们去深研，MYSQL的知识也是先安装好后再过一遍，这样讲课思路OK

一路顺利安装完成，在测试时，云主机也能正常生成，但是终止实例的时候一直删除不了。通过nova service-list和neutron agent-list发现服务也正常启动了，但是nova-compute.log文件里面有报错，goole没查到相关报错信息的处理方法。最后重启了系统，在观察各项服务正常启动后再测试又正常了！
