所有的配置方式都是按照官方的，验证方式也是显示正确，比如service-list，image-list等
但是就是无法创建云主机，返回No valid host was found. 的错误，是不是/etc/hosts里面的127.0.1.1 是不能删除的？

新手上路，急求各位老手的帮助，已经拖了几天了。。

这里说明网络的问题，楼主可以检测下网络的各个服务进程。

这里说的是磁盘已经满了，其它的地方也有类似的，比如内存可能也不够用了。

ERROR nova.compute.manager PortBindingFailed: Binding failed for port bfb8b700-85af-4ff3-9061-0eb684162212, please check neutron logs for more information.
这里说的是端口，应该也是网络的问题

建议先解决上面的问题。


，是不是/etc/hosts里面的127.0.1.1 是不能删除的？
127.0.1.1是可以删除
