KVM Host ssh error

Hello, i have some issue to configure my external kvm host, this is what i had done:

  1. setup Centos 7, disabled selinux, installed epel
  2. added OpenNebula repository and runned yum install opennebula-node-kvm
  3. started and enabled the services: messagebus, libvirtd, nfs
  4. copied the key from my Opennebula server to the kvm host: ssh-copy-id -i /var/lib/one/.ssh/id_rsa.pub oneadmin@XXX.XXX.XXX.XXX
  5. verified that the key has been copied

but i cannot access into from Opennebula to the kvm host using opennebula user still asking the password… what is wrong ?
this is the ssh verbose connection, thanks:

Hi serverx,

Try to chmod your .ssh/config and .ssh/authorized_keys files :

ssh-keygen
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chown oneadmin:oneadmin ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
cat << EOT > ~/.ssh/config
Host *
StrictHostKeyChecking no
ConnectTimeout 5
UserKnownHostsFile /dev/null
EOT
chmod 600 ~/.ssh/config

scp -r ~/.ssh/ oneadmin@YOURHOST:/var/lib/one/

thank you so much… it worked
