我已经使用 openstack-autopilot 安装了 openstack，并尝试使用“从映像启动（创建新卷）”选项启动实例，但是它给了我来自 nova-compute.log 的此错误：

如果我尝试在仪表板中以管理员身份运行，则会出现这些错误；如果我以项目所有者身份运行，则会在 Horizon 中收到此错误：
The requested instance cannot be launched.
Requested volume exceeds quota: Available: 0, Requested: 1.
如果我创建一个卷并附加一个图像，并从该卷创建实例，那么我就可以启动一个实例。
从日志来看，它似乎无法识别可用区域。
任何帮助都非常感谢。
答案1
我在用演示账户登录 UI 时也遇到了类似的问题。我还看到项目演示的配额没问题。但是当我将卷配额从 10 更改为 9 并保存时，我可以正常创建实例。
