请问各位大佬？这怎么解决？
我各个服务都启动正常，都排查了？

Setting instance to ERROR state.

Failed to deallocate networks

No valid host was found. There are not enough hosts avail

通过楼主的帖子发现了以上三个错误，其实应该还有更多的错误，所以建议楼主要综合分析，很多错误是由别的错误引发的。

首先要发现错误，通过下面方法：
openstack排除查找错误的两种方法

对于网络取消分配，network肯定是有错误的，为何会取消分配。也就是network会有更详细的错误，需要到上面去找ERROR。

Setting instance to ERROR state.是指初始化失败，初始化失败所以要设置instance 为错误状态，既然为错误状态，实例初始化失败，肯定是找不到hosts 的，所以根据上面推测是network引发的。当然如果想更准确的定位，楼主还需要去找更多的ERROR及运行信息
