“错误：没有找到有效的主机。没有足够的可用主机”+Newton

Question

我已经在 Ubuntu 16.04（一体机）上安装了 openstack（牛顿版本）。每个服务都运行良好，但是当我尝试启动实例时，出现错误：

错误：无法对实例“test1”执行请求的操作， 实例有错误状态：请稍后再试 [错误：无效 主机被发现。没有足够的主机可用。].

当我进入时：

[root@controller-hp ~(keystone_admin)]$ nova-hypervisor-list
+----+---------------------+-------+---------+
| ID | Hypervisor hostname | State | Status  |
+----+---------------------+-------+---------+
| 1  | controller-hp       | up    | enabled |
+----+---------------------+-------+---------+

和

的输出

我对@9​​87654336@ 图像使用了大风格，这表明问题与资源无关。

这是“tailf /var/log/neutron/neutron-*.log”的输出

这些是我的插件配置：

Linux Bridge Agent

openvswitch

DHCP agent

L3 agent

我已经阅读了这些主题，但它们无法解决我的问题：
