问题描述：
出现这个500错误的原因是python-glanceclient版本过高。当我执行glance image-list   glance image-show f114bed4-2116-4943-92c8-092842370b01 nova image-list的时候都不报错，但是执行nova image-show f114bed4-2116-4943-92c8-092842370b01的时候会返回以下错误：

解决方法：升级一下python-glanceclient的版本，然后重启服务器就可以解决了。。。

你的弄好了吗？我也出现该问题了

具体怎么解决的？能否发下命令，更新后，要重新修改配置文件吗？

请问有谁解决这个问题了的吗，怎么升级

恩，升级了之后就可以了

您好，请问您是怎么升级的，能贴下具体命令吗？

我又用packstack自动安装了一台新机器，结果还是这个错误，也是醉了

我找到问题了，是nova image-show命令会返回500错误。
