在OpenStack图形界面中，怎么创建一台云主机？

Question

用的是OpenStack mirantis，用的是fuel安装。

在新建云主机的时，选择可用区域为空，看到教程上都会出来nova。

强行新建之后，日志提示：

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

消息   No valid host was found. There are not enough hosts available.

还想知道，怎么在OpenStack图形界面中看到当前有哪些控制节点，有哪些计算节点？

Answer 1

1.可用区域是nove端配置有问题，具体看配置文件nova.conf
2,"No valid host was found"很简单，计算节点没配置好，或者网络不通，也可能是你nova端就有问题
