[ovirt-users] Ovirt Cluster SSH key exchange

hi, we have setup a ovirt system with 9 hosts. we will now add three more nodes and we have to exchange from each host the SSH public keys to the other one. we use ovirt 4.3 on centos 7. how did you exchange the SSH keys? did you have ansible to do this or other tools? ssh-copy-id is not the best process here and waste time. br marcel
