 ==========
 OVX is a network hypervisor that can create multiple virtual and programmable networks on top of a single physical infrastructure. Each tenant can use the full addressing space, specify their own topology, and deploy the network OS of their choice. Networks can be reconfigured at run-time, and OVX can automatically recover from physical failures.
 
 Currently, OVX is maintained by Operating Systems Lab, Korea University led by Prof. Chuck Yoo.
