PURPOSE: A virtualization based resource management device, a method thereof, and a system thereof are provided to improve efficiency of the resource management by uniformly managing a plurality of virtual machines and physical machines. CONSTITUTION: A computing system(10) capable of virtualization-based resource management comprises a plurality of physical machines(100_1~100_n), a plurality of virtual machines(400_1~400_n), and a virtual management machine. A plurality of virtual machines is composed with the virtualization of each physical machine. The administration virtual machine is located among a plurality of physical machines in one physical machine. The administration virtual machine performs resource reallocation and resource return through monitoring of time cost of the virtual machine and network usage amount of each physical machine.
