1. A method performed by a control device in a network function virtualization (NFV) environment, the method comprising:
determining a virtual compute node corresponding to a server device;
identifying physical layer information related to the server device, and virtual layer information related to the virtual compute node;
displaying the physical layer information and the virtual layer information; and
examining a malfunction in a virtual layer to detect a malfunction in at least one virtual machine, VM, which operates in the virtual compute node,
wherein association between the physical layer information and the virtual layer information is used to manage quality of service, QoS, in the NFV environment;
in case that a malfunction is not detected in the virtual layer, examining a malfunction in a server device associated with the virtual layer and a physical port of the server device;
in case that a malfunction is not detected in the server device and the physical port, examining a malfunction in a switch connected to the physical port of the server device and a port of the switch,
in case that a malfunction is not detected in the switch and the port of the switch, determining no malfunction is occurred in an infrastructure and a service, and displaying that it is necessary to examine a software running on the at least one VM,
in case that a malfunction is detected in at least one of the virtual layer, the server device, the physical port, the switch, and the port of the switch, displaying information indicating the malfunction of the at least one VM, information indicating the server device including the physical port corresponding to the at least one VM, information of the switch connected to the physical port, and virtual layer information related to the at least one VM;
in case that a malfunction is detected in the physical port and a sum of traffic usage of the at least one VM is not supported, notifying through a user interface that the physical port is down; and
in case that a malfunction is detected in the physical port and a sum of traffic usage of the at least one VM is not supported, controlling one of the at least one VM to stop an operation without notification.
