The sections above, guide you though the actions needed to create a synnefo backend. Once you have at least one backend up and running you can go back to the cyclades section, add the backend, create a public network and have full Synnefo functionality.

In the following sections we will refer to the following roles:

• ganeti (all nodes of a Ganeti cluster/synnefo backend)
• master (ganeti master node)
• router

Please note that all these roles can be “played” by the same node.

Prerequisites:

master:

• Available master IP that resolves to FQDN (ganeti.example.com)

ganeti:

• primary interface: eth0 with IP that resolves to FQDN (nodeX.example.com)
• /etc/hosts: hostname should not resolv to 127.* address.
• /etc/ssh/ssh_host_rsa_key*: must be identical among all nodes.
• extra interfaces: eth1, eth2 (vlans can be used too)
• NFS mount point: /srv/pithos
• lvm: Volume Group named ganeti

router:

• primary interface: eth0 with public routable IP
• extra interfaces: eth1, eth2 (vlans can be used too) connected with ganeti nodes
