    • There is provided an apparatus and method for executing live-migrations concurrently on a plurality of virtual machines. Resource-usage state information is acquired from each of the plurality of virtual machines when a first live migration of a first virtual machine is started. A correlation factor indicating a degree of correlation between first resource-usage state information for the first virtual machine and second resource-usage state information for each of one or more virtual machines other than the first virtual machine is calculated using the acquired resource-usage state information. Next, a second virtual machine having a positive correlation factor with respect to the first virtual machine is selected from the one or more virtual machines where the positive correlation factor indicating a close similarity between the first and second resource-usage state information. Then, a second live-migration is executed on the second virtual machine in parallel with the ongoing first live migration.
    • 提供了一种用于在多个虚拟机上同时执行实时迁移的装置和方法。 当第一虚拟机的第一次实时迁移开始时,从多个虚拟机中的每一个获取资源使用状态信息。 使用所获取的资源使用状态来计算表示第一虚拟机的第一资源使用状态信息与第一虚拟机以外的一个以上的虚拟机的第二资源使用状态信息之间的相关程度的相关因子 信息。 接下来,从表示第一和第二资源使用状态信息之间的密切相似性的正相关因子的一个或多个虚拟机中选择具有相对于第一虚拟机的正相关因子的第二虚拟机。 然后,与正在进行的第一次实时迁移并行地在第二虚拟机上执行第二次实时迁移。

    • A computer-readable medium stores therein an information processing program that causes a computer to execute a process. The process includes referring to relationship property information records that are stored in a storage device and indicate the type of each relationship property between configuration elements in a system and calculating a total count of configuration elements having a predetermined relationship property with a first configuration element, or a total count of relationship property information records having a predetermined relationship property, among relationship property information records concerning the first configuration element; executing conditional determination concerning the number of configuration elements having the predetermined relationship property with the first configuration element, among the calculated total count of configuration elements or the calculated total count of relationship property information records; and outputting a result of the determination.
    • 计算机可读介质中存储有使计算机执行处理的信息处理程序。 该处理包括参考存储在存储装置中的关系属性信息记录,并指示系统中的配置元素之间的每个关系属性的类型,并计算与第一配置元素具有预定关系属性的配置元素的总数,或 关于第一配置元素的关系属性信息记录中具有预定关系属性的关系属性信息记录的总计数; 计算出配置要素总计数或所计算出的关系属性信息记录总计数的关于具有与第一配置元素具有预定关系属性的配置元素的数量的条件确定; 并输出确定的结果。
