No. The playbook won't neither do \*ssh-copy-id\* nor will it copy  
public keys from each host in rhev\_hosts to every other host in that  
host group. The playbook will read /root/.ssh/id\_rsa.pub on the  
controller and insert this public key into the root's authorized\_key  
file on each host in the group rhev\_hosts.

Notes:  
\* lookup always works on the controller.  
\* It is a bad idea to use root account on the Ansible controller to  
&nbsp;&nbsp;run a playbook.  
\* It is also a bad idea to ssh to root on the remote host.  
\* The module ansible.posix.authorized\_key doesn't use \*ssh-copy-id\*  
&nbsp;&nbsp;utility. It writes the file authorized\_key directly.
