可见是云主机调度错误 uuid是这台 93e30e33-d136-43bb-b5a2-9c1bd9f5519f 云主机创建失败被回滚删了。

先去nova scheduler上查日志。

scheduler节点较多，要一个一个节点上去看日志。没有elk好苦

2017-02-22 14:31:21.894 173557 INFO nova.scheduler.filter_scheduler [req-b0ce6a30-03c0-4ceb-88d8-2d031b5f4f6c 8cd57421117640a0aa7012878dc53aa1 56ef8405224b44fea50ec80cbfce8fed] Choosing host WeighedHost [host: pubt1-nova21.yq.163.org, weight: 48709.0] for instance 93e30e33-d136-43bb-b5a2-9c1bd9f5519f

看到这，说明调度选择到 pubt1-nova21.yq.163.org 这个节点上去了。我们接下来跳到这个节点看nova compute 日志。

关键信息 nce/pubt1 has no valid network。nce网段没有。

使用neutron 查询一下

neutron vnet-binding-list --tenant-id 56ef8405224b44fea50ec80cbfce8fed
+--------------------------------------+----------+--------------------------------------+-------+
| id                                   | vnetwork | network_id                           | az    |

+--------------------------------------+----------+--------------------------------------+-------+

可见vnet中的确没有。

原因，初始化的时候没有走完nce的流程，让底层同学帮直接初始化了。

那解决的办法是可以帮他绑上一个nce的vnet。

先找个正常的通过nce初始化的租户，查询一下

neutron vnet-binding-list --tenant-id 6596d85821c54c16a70d919aa79c1bbc
+--------------------------------------+----------+--------------------------------------+-------+
| id                                   | vnetwork | network_id                           | az    |
+--------------------------------------+----------+--------------------------------------+-------+

| 4335aed2-4b0b-4b0a-8410-33440831a48e | nce      | 5646d40e-637c-4ce4-b306-cb5e62648a9c | pubt1 |
| b96f2bde-9345-4be3-a87f-96ab260cbffd | private  | d3ed1a4a-b4b9-430e-b147-180472fc3aeb | pubt1 |
+--------------------------------------+----------+--------------------------------------+-------+

然后帮他绑上

neutron vnet-binding-create --tenant-id 56ef8405224b44fea50ec80cbfce8fed --vnet nce    --network   5646d40e-637c-4ce4-b306-cb5e62648a9c    --az pubt1

done！
