Abstract
Load leveling between hosts (computes) is realized in a virtual infrastructure regardless of application restrictions on the virtualization technique and by reducing the influence on services. A load leveling apparatusincludes: a load determination unitthat acquires load information for a computeof each VM, calculates a load of each computeby totaling the load information for every computein which the VMs are disposed, calculates a standard deviation of the load of each compute, and, in a case where the calculated standard deviation is larger than a predetermined reference standard deviation, determines that there is a large load bias; a VM disposition determination unitthat extracts the computehaving the highest load among the loads of the computes, selects a VMdisposed in the compute, specifies a VMforming a pair with selected VM, and determines the pair of VMsas a pair of VMs for switching; and a switching instruction unitthat outputs instruction information for switching the determined pair of VMs.
