首先这个问题比较复杂了。首先but知道计算结点是否安装成功。这里面涉及到网络和控制结点。而且看到控制结点楼主有多个。是否有失败的。添加计算结点又是按照什么文档操作的

问题挺大的，需要具体某一个问题。否则根本看不过来。
也可以把相关具体问题都列出来。
比如进程看不到，服务没起来。添加失败，看看到底哪里导致的，先定位基本的问题，或则分析出来导致这个原因的进程。比如网络原因，cinder，或则控制节点的原因等.这样才有个方向。

根据提供的错误，初步判断
1.确定租户的资源是充足的，每个租户默认应该只能创建10个实例
2.ERROR nova.compute.manager这个错误，只能说明计算节点的问题，具体是什么原因，还需查看详细日志。比如因为网络或则其它原因
