虛擬機叢集之動態資源分配方法 Method of dynamic resource allocation for a virtual machine cluster
A method of dynamic resource allocation for a virtual machine cluster is to calculate the resource usage weight of the respective virtual machine, the resource usage weight of the respective physical machine, and the average resource usage weight of the physical machines, to pick the physical machine with the greatest resource usage weight as the migration source machine, to pick the physical machine with the least resource usage weight as the migration object machine, and to move the virtual machine in the migration source machine with the resource usage weight thereof being closest to the migration difference value to the migration object machine to achieve the effect of load balancing.

一種綠能管理方法，係以虛擬機叢集之總使用資源權值比，來判斷應否增開或關閉實體機器之運轉。當總使用資源權值比高於最大容許使用資源權值比時，自非運轉中之實體機器中選擇一備用實體機器，並將其喚醒加入成為運轉中之實體機器，另外，當總使用資源權值比低於最小臨界使用資源權值比時，自運轉中之實體機器中選擇一遷移實體機器，並將其中之虛擬機器遷移至其他運轉中之實體機器後再予關閉，以及執行一資源分配程序，以分配運轉中之實體機器的負載。因此，可靈活地調度運轉中之實體機器的數量，達成綠能管理的目的。
