通过在 OpenStack 中创建实例，IP 被注入到实例中，而不是像主机名和密钥对中的其他元数据。nova 和 neutron 日志文件中没有错误。
问题：
...

上面的代码片段是 Cirros 实例创建日志的一部分。（创建过程的完整日志在这里发布）
日志中的另一个错误是这一行：
acpi PNP0A03:00: fail to add MMCONFIG information, can't access extended PCI configuration space under this bridge。这与问题有关吗？
一些配置文件：

以下是来自cloud-init.log实例的错误：

自创建实例以来，
- neutron-metadata-agent.log：空！
- 中子服务器日志：http: //sprunge.us/a27LHT
- nova-compute.log：http ://sprunge.us/sl8eu7
