本篇文章給大家分享的是有關上傳的鏡像無法用來啟動云主機怎么辦，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。
Openstack各功能正常，使用其它鏡像創建云硬盤并用來啟動云主機也正常，但是就是這個鏡像有問題。

錯誤里提示要求neutron的認證，突然靈光一閃想起來這個虛擬機鏡像cirros是一開始安裝完glance服務上傳測試用的，那個時候還沒有對接ceph，也就是說這個鏡像并不是存儲在ceph里的。重新上傳一個cirros的鏡像，啟動云主機成功。
另外因為更改了glance的存儲后端，導致原先的鏡像無法刪除，有兩種解決辦法：
1、修改glance-api.conf,改回原先的配置，重啟glance的相關服務，再刪除，刪除之后再改成新的配置重啟服務
2、直接修改元數據庫，在glance庫中，image_locations和images表記錄了鏡像的存儲信息。
