Later on, when defining the network in OpenNebula, you will specify the name of this bridge and OpenNebula will know that it should connect the VM to this bridge, thus giving it connectivity with the physical network device connected to the bridge.SIMATIC STEP 7 is the world's best known and most widely used engineering software in industrial automation. For this driver, you will need to setup a Linux bridge and include a physical device in the bridge. You may want to use the simplest network model, that corresponds to the bridged driver. There are various models for Virtual Networks, check the Open Cloud Networking chapter to find the ones supported by OpenNebula. It is highly recommended to use a dedicated network for this purpose. Network connection is needed by the OpenNebula Front-end daemons to access, manage and monitor the Hosts, and to transfer the Image files.

It should be executed on your Front-end under oneadmin user and copied on all your Nodes.

The file is located in /var/lib/one/.ssh/known_hosts and we can use the command ssh-keyscan to manually create it. known_hosts) so that all communicating parties know the identity of the other sides. You should prepare and further manage the list of host SSH public keys of your nodes (a.k.a. To learn more about the SSH, read the Advanced SSH Usage guide. While the authentication agent is used, you donвЂ™t need to distribute private SSH key from Front-end to hypervisor Nodes! Access to this agent is delegated (forwarded) from the OpenNebula Front-end to the hypervisor Nodes for the operations which need to connect between Nodes or back to the Front-end. On the Front-end runs dedicated SSH authentication agent service which imports the oneadminвЂ™s private key on its start. In this guide, we are going to manually use SSH tools. Ultimately the administrator should choose a method the recommendation is to use a configuration management system (e.g., Ansible or Puppet). There are many methods to achieve the distribution of the SSH keys. To enable passwordless connections you must distribute the public key of the oneadmin user from the Front-end to /var/lib/one/.ssh/authorized_keys on all hypervisor Nodes. It happens only if these files donвЂ™t exist yet, existing files (e.g., leftovers from previous installations) are not touched! For new installations, the default SSH configuration is placed for the oneadmin from /usr/share/one/ssh into /var/lib/one/.ssh/config. When OpenNebula server package is installed on the Front-end, a SSH key pair is automatically generated for the oneadmin user into /var/lib/one/.ssh/id_rsa and /var/lib/one/.ssh/id_rsa.pub, the public key is also added into /var/lib/one/.ssh/authorized_keys.

It must be ensured that Front-end and all Nodes can connect to each other over SSH without manual intervention.
