Public bug reported:
My existing CentOS 6.7 qcow2 image had ssh password authentication
disabled. To remedy this I made necessary changes
#vi /etc/ssh/sshd_config
comment PasswordAuthentication no and uncomment PasswordAuthentication yes.
#sudo service sshd restart
#chkconfig --level 5 sshd on
in an instance running this image. Then, after shutting it down
(checked pausing it too) I took snapshot of it from cli.
[root@node-61 ~]# nova --version
2.18.1
[root@node-61 ~]# nova image-create e25a6289-d3f3-4ed1-8ab3-c4b828963c85
Meghadoop_snapshot_ready
Now, If I instantiate a new VM with the created snapshot
"Meghadoop_snapshot_ready", the changes made to sshdconfig is not
reflected i.e. the new VM's sshdconfig has PasswordAuthentication no.
However, the original instance, as expected, retains the changes made to
sshdconfig after starting (or resuming). So I guess this is not due to
dirty OS buffers etc.
