A private cloud is built upon a virtualized network, along with storage and compute resources. Many virtual networks are overlaid on top of the shared physical network, logically separating tenants on the shared resources. One challenge is that the physical network lacks visibility into the topology of the overlays. A second obstacle is that network overlays utilizing standard vSwitches do not allow for security and network policies to live-migrate with VMs.
