I found a crucial clue.
When I tried to create an instance, every time, I got the error messages
repeated continuously.
It is from the log file of node2, /var/log/nova/nova-compute.log:

 Above logs all occurred with only one instance creation.
Although I already searched the internet, I found nothing meaningful.

Just, I'm guessing that when I requested an instance creation on the
controller node, it delivered the request with an empty parameter, which
was deemed to None type. I mean, the empty one is password.

However, I'm confused because I have set all the config files which the
official documentation guided to add.
As I think, the main issue is the reason the instance creation request was
sent to 'node2' without password parameter.
Have you ever seen the error message I had?
