按照官方文档部署openstack的O版，创建实例失败

[yanghuabin1202]

在完成openstack主要组件的部署后，并且每个组件都进行过验证，但在创建实例时失败

希望大神能够指点迷津，帮忙确认一下是哪里出了错误！

@yanghuabin123 去看下/var/log/nova/nova-api.log 日志文件里说的错，你应该是遇见bug了。

很多服务中都出现了同样的问题，也不知道是哪里出了问题。 ● openstack-nova-consoleauth.service - OpenStack Nova VNC console auth Server Loaded: loaded (/usr/lib/systemd/system/openstack-nova-consoleauth.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2017-09-25 20:45:11 CST; 19min ago Main PID: 932 (nova-consoleaut) CGroup: /system.slice/openstack-nova-consoleauth.service └─932 /usr/bin/python2 /usr/bin/nova-consoleauth Sep 25 20:43:31 controller systemd[1]: Starting OpenStack Nova VNC console auth Server...

启动实例失败后，看/var/log/nova/nova-api.log 日志，也看不出出了什么错。

一个服务一个服务的排查， 例如keystone 例如nova 例如neutron 看日志，提示比较全了. 你这大面积报错，不好定位，或者说有很多错误. 一个一个来解决。
