You can use SDN (Software Defined Networking). Salvatore sent some mails about the work he had done which got to a beta state. It sets up zone-wide L2 overlay networks using GRE tunnels. Salvatore's work was XenServer specific and used a controller native to CloudStack. Hugo has done some commits on Nicira NVP integration as well. SDN is bleeding edge for CloudStack now but is an interesting future direction. Would be great to get some feedback on these features.
