Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. [Wed May 24 13:59:15.475574 2017] [wsgi:error] [pid 8013:tid 140130413639424] (HTTP 500) (Request-ID: req-d786ae6a-f413-4654-b8d8-0297a0c5f52b) ``` 2. LOG如果出現:DBError: (pymysql.err.InternalError) (1054, u“Unknown column 'XXXXXXXXXXX 'field list'”) 請重新sync db ``` # su -s /bin/sh -c "xxxxx-manage db_sync" xxxxx ``` 3. 建立VM噴錯 因為compute上的nova-compute有問題，只要建立VM，nova-compute就會死掉: ``` Failed to perform requested operation on instance "test", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.]. ``` 4. 無法進入dashboard，查看apache2 error.log ImportError: cannot import name security\_group\_rules 然後在controller輸入 openstack flavor list，出現下錯誤 ``` Unable to establish connection to http://controller:8774/v2.1/3fa5fc21995f4bf2b2da8d3073d9b819/flavors/detail: HTTPConnectionPool(host='controller', port=8774): Max retries exceeded with url: /v2.1/3fa5fc21995f4bf2b2da8d3073d9b819/flavors/detail (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',)) ``` 之後查看nova所有服務，發現狀態為dead，重啟後為active，但是再下一次openstack flavorlist或重整網頁，nova所有服務又死了
