 #In case some of the previous 'bridge_ifaces' are connected to an EXTERNAL dhcp server, provide 
 #   the server parameters to allow openvim getting the allocated IP addresses of virtual machines
 #   connected to the indicated 'bridge_ifaces' and or 'nets'. Openvim will connect to the dhcp server by ssh.
