METHOD AND DEVICE FOR DYNAMICALLY ALLOCATING RESOURCES TO A PLURALITY OF VIRTUAL MACHINES

摘要

PROBLEM TO BE SOLVED: To provide a dynamic resource allocating method for allowing a host server to adjust a plurality of virtual machines by sensing a change in a resource request of the respective virtual machines in real time.;SOLUTION: This method includes steps of: monitoring activity of the application in the respective virtual machines executed on the host server, determining priorities of the application in the respective virtual machines based of the activity of the monitored application, setting the priorities of the respective virtual machines based on the determined priority of the application in the respective virtual machines, and dynamically adjusting resource allocation to the respective virtual machines by the host server based on the priorities of the respective virtual machines. Resources of the host server can be dynamically allocated to the respective virtual machines according to a real-time resource request of the operation application of the respective virtual machines.;COPYRIGHT: (C)2009,JPO&INPIT
