A virtualization controller may select a physical device as a root device of a virtual device, and select a physical device as a leaf device of the virtual device. The virtualization controller may obtain a user network interface (UNI) on the leaf device, establish a virtual interface on the root device for the UNI, and record a relation which associates the UNI with the virtual interface. The virtualization controller may control the root device and the leaf device to establish a virtual tunnel between the UNI and the virtual interface through which the root device and the leaf device may exchange data. |
