The processing performance of an entire system is enhanced by efficiently using CPU resources shared by a plurality of guests. A serverincludes a host OSand a plurality of guest OSsA andB running on a plurality of virtual machinesA andB, respectively, which are virtually constructed on the host OS. The plurality of virtual machinesA andB shares CPU resources implemented by hardware. A guest priority calculation unitof a resource management device (resource management unit) calculates a processing priority of at least one of the guest OSsbased on at least one of a packet transfer rate from the host OSto the guest OSand an available capacity status of a kernel buffer of the host OS. A resource utilization control unitcontrols allocation of a utilization time for CPU resources to be used by the plurality of guest OSsbased on the calculated processing priority.

Resource management device and resource management method

Resource use efficiency is improved while realizing quality guarantee of an application. A resource allocation device includes a storage unit that stores resource capacity information indicating a capacity of each of server resources, an SLI information collection unit that acquires information regarding an SLI at a predetermined time interval with regard to each of a plurality of applications, and a resource allocation determination unit that calculates an allocation resource amount of each application using a moving average and a standard deviation of the acquired information regarding the SLI during a predetermined period, and determines server resources which are allocation destinations of the applications by sorting the applications in descending order of the allocation resource amounts and sequentially adding the allocation resource amounts of the sorted applications within a range which does not exceed a capacity of each server resource in descending order of the allocation resource amounts.
