Virtualization-based resource management apparatus and method and computing system for virtualization-based resource management

A virtualization-based resource management apparatus performing resource management of a computing system including a plurality of physical machines and a plurality of virtual machines configured by virtualizing each of the plurality of physical machines, the virtualization-based resource management apparatus comprising:

• a processor;
• a memory;
• and
• a non-transitory computer readable medium with computer readable instructions stored thereon, which, when executed by a processor, perform the following steps:
• measuring a time taken for the management virtual machine to read information on a list of the plurality of virtual machines, read information on a list of the plurality of physical machines, reading information on an amount of resources used, and read information on a resource allocation relationship;
• determining whether the measured time falls within an allowable range;
• if the measured time falls within the allowable range, comparing an amount of network resources used by a first physical machine on which the management virtual machine is located to a threshold value;
• if the amount of network resources exceeds the threshold value, migrating the management virtual machine to a second physical machine;
• if the measured time exceeds the allowable range, allocating additional resources to the management virtual machine;
• if the measured time is less than the allowable range, reclaiming resources allocated to the management virtual machine and allocating the reclaimed resources to machines other than the management virtual machine.

• if the measured time exceeds the allowable range, allocating additional resources to the management virtual machine;
• if the measured time is less than the allowable range, reclaiming resources allocated to the management virtual machine and allocating the reclaimed resources to machines other than the management virtual machine.

A virtualization-based resource management method of a management virtual machine located at any one of a plurality of physical machines where one or more virtual machines are executed, the virtualization-based resource management method comprising:

• selecting a physical machine that uses the least amount of network resources among the plurality of physical machines, and positioning the management virtual machine to the selected physical machine;
• collecting and managing information on the one or more virtual machines;
• measuring a time taken for the management virtual machine to read information on a list of the plurality of virtual machines, read information on a list of the plurality of physical machines, reading information on an amount of resources used, and read information on a resource allocation relationship;
• determining whether the measured time falls within an allowable range;
• if the measured time falls within the allowable range, comparing an amount of network resources used by a first physical machine on which the management virtual machine is located to a threshold value;
• if the amount of network resources exceeds the threshold value, migrating the management virtual machine to a second physical machine;
• if the measured time exceeds the allowable range, allocating additional resources to the management virtual machine;
• if the measured time is less than the allowable range, reclaiming resources allocated to the management virtual machine and allocating the reclaimed resources to machines other than the management virtual machine.
