Hi,

I created an instance in OpenStack. It shows that’s its up and running but
I cannot ping or ssh to it. I added security group as default and port 22
open rules to the security group and assigned it to my instance. But still
can't ping or ssh to it.

Error message displays was
     ssh: connect to host 10.0.0.2 port 22: No route to host

Below details were from command line using nova command
