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

stance解決
錯誤里提示要求 neutron 的認(rèn)證，突然靈光一閃想起來這個虛擬機(jī)鏡像 cirros 是一開始安裝完 glance 服務(wù)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(jī)成功。
另外因為更改了 glance 的存儲后端，導(dǎo)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(guān)服務(wù)，再刪除，刪除之后再改成新的配置重啟服務(wù)
2、直接修改元數(shù)據(jù)庫，在 glance 庫中，image_locations 和 images 表記錄了鏡像的存儲信息。
