Introduce /etc/network/interfaces.synnefo that will setup bridges used for VMs' public and private networks. Instead of using a common bridge use two separate bridges (br0, prv0). Their default ports are defined in nodes.conf (vm_public_iface, vm_private_iface) which are by default dummy. In a single node setup we don't need those interfaces. In case of router node, br0 will get the gateway IP. Use ferm for persistent network configuration. Add masq.ferm that is responsible for masquerading on router node and MAC SNAT on all nodes (needed in case we have a MAC filtered setup on vm_public_iface). Use rc.local to losetup extra disk and ifup bridges. Signed-off-by: Dimitris Aragiorgis <dimara@grnet.gr>
