1. A method comprising:
- monitoring, by a processor, while an additional virtual machine is under an activation process to be launched on a management target system on which a plurality of virtual machines are executing, a load of hardware resources used by the plurality of executed virtual machines on the management target system;
cancelling, by the processor, the activation process to launch the additional virtual machine, in response to the monitoring detecting a decrease of the load of hardware resources of the management target system; and
issuing, by the processor, to the management target system an instruction to stop an additional virtual machine, among other additional virtual machines, under the activation process for which an activation start time is more recent than the other additional virtual machines under the activation process, in response to an instruction to decrease a resource of the management target system.

Abstract
A method includes monitoring a load of a management target system on which a plurality of virtual machines are executed, cancelling an instruction to activate a virtual machine according to the monitored load and a status of the virtual machine for which the instruction to activate the virtual machine is previously given to the system and which is still under the activation process; and issuing an instruction to the system to stop the virtual machine which is still under an activation process according to the monitored load and the status of the virtual machine.

5. An apparatus comprising:
-
a memory; and a processor coupled to the memory and configured to execute a process comprising; monitoring while an additional virtual machine is under an activation process to be launched on a management target system on which a plurality of virtual machines are executing, a load of hardware resources used by the plurality of executed virtual machines on the management target system; cancelling the activation process to launch the additional virtual machine, in response to the monitoring detecting a decrease of the load of hardware resources of the management target system; and issuing to the management target system an instruction to stop an additional virtual machine, among other additional virtual machines, under the activation process for which an activation start time is more recent than the other additional virtual machines under the activation process, in response to an instruction to decrease a resource of the management target system. - View Dependent Claims (6, 7, 8)

9. A non-transitory computer-readable medium storing therein a program that causes the computer to execute a process, the process comprising:
-
monitoring while an additional virtual machine is under an activation process to be launched on a management target system on which a plurality of virtual machines are executing, a load of hardware resources used by the plurality of executed virtual machines on the management target system; cancelling the activation process to launch the additional virtual machine, in response to the monitoring detecting a decrease of the load of hardware resources of the management target system; and issuing to the management target system an instruction to stop an additional virtual machine, among other additional virtual machines, under the activation process for which an activation start time is more recent than the other additional virtual machines under the activation process, in response to an instruction to decrease a resource of the management target system. - View Dependent Claims (10, 11, 12)
