Openstack之Queen版本启动实例ssh连接实例问题（未解决）

Posted 2020-11-26 pan-xi-yi

问题描述

使用http://cloud.centos.org/centos/7/images提供的镜像。

下载链接：https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1907.raw.tar.gz?，（windows 下载似乎更快），再上传到vmvare，进行转换位qcow2格式。

转换：

#首先解压，压缩后的镜像比较小，下载也比较快
$ tar -zxvf CentOS-7-x86_64-GenericCloud-1907.raw.tar.gz
#转化镜像格式，raw格式转化为qcow2格式
$ qemu-img convert -f raw -O qcow2 CentOS-7-x86_64-GenericCloud-1907.raw CentOS-7-x86_64-GenericCloud-1907.qcow2
$ ls
CentOS-7-x86_64-GenericCloud-1907.qcow2

状态查看

启动实例时一切（电源状态，实例状态）都正常。

看dashboard的日志好像是说没有将ssh指定的key注入到镜像中。。

ssh登陆

尝试一下，使用ssh指定私钥文件进行登陆，似乎失败了。

暂时未解决！！！
