本篇文章給大家分享的是有關(guān)上傳的鏡像無(wú)法用來(lái)啟動(dòng)云主機(jī)怎么辦，小編覺(jué)得挺實(shí)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(shuō)，跟著小編一起來(lái)看看吧。
成都創(chuàng)新互聯(lián)-專業(yè)網(wǎng)站定制、快速模板網(wǎng)站建設(shè)、高性價(jià)比瑞安網(wǎng)站開(kāi)發(fā)、企業(yè)建站全套包干低至880元,成熟完善的模板庫(kù),直接使用。一站式瑞安網(wǎng)站制作公司更省心,省錢(qián),快速模板網(wǎng)站建設(shè)找我們，業(yè)務(wù)覆蓋瑞安地區(qū)。費(fèi)用合理售后完善，十載實(shí)體公司更值得信賴。
Openstack各功能正常，使用其它鏡像創(chuàng)建云硬盤(pán)并用來(lái)啟動(dòng)云主機(jī)也正常，但是就是這個(gè)鏡像有問(wèn)題。

錯(cuò)誤里提示要求neutron的認(rèn)證，突然靈光一閃想起來(lái)這個(gè)虛擬機(jī)鏡像cirros是一開(kāi)始安裝完glance服務(wù)上傳測(cè)試用的，那個(gè)時(shí)候還沒(méi)有對(duì)接ceph，也就是說(shuō)這個(gè)鏡像并不是存儲(chǔ)在ceph里的。重新上傳一個(gè)cirros的鏡像，啟動(dòng)云主機(jī)成功。
另外因?yàn)楦牧薵lance的存儲(chǔ)后端，導(dǎo)致原先的鏡像無(wú)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(kù)，在glance庫(kù)中，image_locations和images表記錄了鏡像的存儲(chǔ)信息。
