现有的虚拟机能耗计算方法,首先是在物理机上选择一些典型的物理资源,如CPU、存储设备、网络I/O作为划分物理机系统能耗的功能单元,根据经验为每个功能单元选择一个或多个能够体现该功能单元的工作量的事件计数器,例如CPU利用率,实时采集物理机上这些事件计数器的统计信息,根据各个功能单元对应的一个或多个事件计数器的汇总的统计信息与物理机的总能耗进行建模,得到每个功能单元的统计信息与物理机能耗的模型,模型中包括每个功能单元的单位工作量对应的能耗系数,然后,根据所有事件计数器的统计信息中包含的虚拟机标识,获得每个虚拟机对应的各种事件计数器的统计信息,按照每个虚拟机的各功能模块对应的事件计数器的统计信息得到每个虚拟机的各功能模块对应的能耗,对每个虚拟机对应的各个功能模块的各个事件计数器的能耗求和,得到每个虚拟机的能耗。

本发明实施例提供的虚拟机能耗确定方法,通过根据所述物理机上的特征信息,以及所述物理机的非映射基础能耗,确定所述物理机的能耗模型,所述非映射基础能耗为物理机的未运行虚拟机时的能耗中未映射到所述特征信息的能耗,并根据所述物理机能耗模型确定所述物理机上运行的虚拟机的能耗,由于该物理机能耗模型中与特征信息对应的能耗参数矩阵的确定考虑了物理机的基础能耗中的特征信息对特征信息的水平变化对物理机总能耗的影响,物理机能耗中与特征信息有关的能耗参数更准确,因此,本发明实施
例提供了一种更准确的虚拟机能耗确定方法。进一步地,采用本发明实施例的确定虚拟机能耗的方法,在物理机运行阶段可以不必在物理机安装电表等能耗测量设备获取物理机的实时能耗,降低了物理机供应商的设备投资成本。
图4为本发明提供的虚拟机能耗确定方法实施例二的流程图,在图1至图3所示方法的基础上,如图4所示,本发明实施例的步骤包括:
与图1至图3所示方法不同的是,若所述物理机上的特征信息中可以包括CPU资源的值、内存资源的值、IO资源的值,
则S1021-01所述获取至少一组历史参数矩阵和历史可变能耗因子,每组所述历史参数矩阵和历史可变能耗因子根据一组历史特征信息和物理机的历史能耗和物理机的非映射基础能耗确定,可以具体包括:

其中,所述预设的特征信息的利用率区间组合条件为预设的物理机的CPU资源的利用率区间、内存资源的利用率区间、IO资源的利用率区间的组合,所述物理机的CPU资源的利用率区间包括预设的第一CPU资源利用率区间、第二CPU资源利用率区间、第三CPU资源利用率区间,所述内存资源的利用率区间包括预设的第一内存利用率区间、第二内存利用率区间、第三内存利用率区间,所述IO资源的利用率区间包括预设的第一IO资源利用率区间、第二IO资源利用率区间、第三IO资源利用率区间。
S1021-02所述从至少一组历史参数矩阵和历史可变能耗因子中,选择与所述物理机的特征信息满足预设的匹配条件的历史特征信息对应的历史参数矩阵和历史可变能耗因子,作为所述物理机的能耗模型中的所述设定的参数矩阵和设定的可变能耗因子,可以具体包括:
S1021-12、从至少一组历史参数矩阵和历史可变能耗因子中,选择与所述物理机的特征信息中的CPU资源的值、内存资源的值、IO资源的值所属的利用率区间的组合相同的历史特征信息对应的历史参数矩阵和历史可变能耗因子,作为所述物理机的能耗模型中的所述设定的参数矩阵和所述设定的可
变能耗因子。
需要说明的是,所述预设的第一、第二和第三CPU资源利用率区间可以是分别是CPU资源利用率为50%至100%、30%至50%,0%至30%,相应的,所述预设的内存资源利用率区间和所述预设的IO资源利用率区间的设置可以参考CPU资源利用率区间的设置,本发明不做限制。当物理机的CPU资源利用率为50%至100%时,可以称之为物理机的能耗状态为CPU密集型,当物理机的内存资源利用率为50%至100%时,可以称之为物理机的能耗状态为内存密集型,当物理机的IO资源利用率为50%至100%时,可以称之为物理机的能耗状态为IO密集型。
本发明实施例通过划分利用率水平区间的历史特征信息确定的历史参数矩阵和历史可变能耗因子确定虚拟机能耗,并选择与当前物理机的特征信息的历史特征信息所述的利用率水平区间组合相同的历史参数矩阵和历史可变能耗因子确定物理机能耗模型,并进一步根据该物理机能耗模型确定虚拟机的能耗,由于该物理机能耗模型体现的物理机的能耗状态更接近物理机当前的特征信息对应的能耗状态,使得虚拟机能耗的确定更准确。
图5为本发明提供的虚拟机能耗确定方法实施例三的流程图,图6为图5所示方法的第二种流程图,在图1至图4所示方法的基础上,如图5所示,本发明实施例的步骤包括:
与图1至图4所示方法不同的是,若所述物理机和所述物理机上运行的第一虚拟机的CPU资源的值均属于预设的第一CPU资源利用率区间,且所述预设的第一CPU资源利用率区间的最小值不低于50%,或者,

则S102所述根据所述物理机上的特征信息,以及所述物理机的非映射基础能耗,确定所述物理机的能耗模型,还可以包括S1023和S1024:
S1023、根据所述物理机上运行的除所述第一虚拟机之外的第二虚拟机的特征信息,确定用于计算所述第二虚拟机的能耗的设定的参数矩阵和设定的可变能耗因子;
需要说明的是,所述第一虚拟机的CPU资源的值与所述物理机的CPU资源的值均是相对于所述物理机总的CPU可用资源而言的,举例来说,所述物理机的CPU资源的值为80%,所述物理机上运行有两个虚拟机,两个虚拟机的CPU资源的值可以是30%和50%。进一步地,当第一虚拟机的CPU资源的值和物理机的CPU资源的值分别为70%和80%,预设的第一CPU利用率区间为50%至100%,则所述物理机和所述第一虚拟机的CPU资源的值均属于第一CPU资源利用率区间,这种情况实际上表面物理机处于CPU密集型的能耗状态,而这种能耗状态是由该第一虚拟机造成的。因此,对该第一虚拟机继续使用根据物理机的特征信息确定的物理机能耗模型确定该第一虚拟机的能耗,而对物理机上除所述第一虚拟机之外的其他虚拟机,可称为第二虚拟机,使用根据第二虚拟机的特征信息确定的物理机的能耗模型确定其能耗将更准确。
具体的,可参考图6,S1023可以具体包括:
S1023-1、获取所述第二虚拟机的特征信息;
S1023-2、从至少一个历史参数矩阵和历史可变能耗因子中,选择与所述物理机上运行的第二虚拟机的特征信息所属的利用率水平区间组合相同的历史特征信息对应的历史参数矩阵和历史可变能耗因子,作为用于计算所述第二虚拟机的能耗的物理机的能耗模型中的所述设定的参数矩阵和设定的可变能耗因子。
其中,所述利用率区间组合包括所述CPU资源的利用率区间、内存资源的利用率区间、IO资源的利用率区间,所述CPU资源的利用率区间包括预设的第一CPU资源利用率区间、第二CPU资源利用率区间、第三CPU资源利用率区间,所述内存资源的利用率区间包括预设的第一内存利用率区间、第二内存利用率区间、第三内存利用率区间,所述IO资源的利用率区间包括预设的第一IO资源利用率区间、第二IO资源利用率区间、第三IO资源利用率区间。

所述物理机空闲能耗之和,确定为用于计算所述第二虚拟机的能耗的所述物理机的能耗模型。
其中,所述特征矩阵包括以下至少一种矩阵元素:CPU资源、内存资源、输入输出IO资源和网络流量,或者,所述特征矩阵包括以下至少一种矩阵元素:执行的指令数、LLC数、中断计数器的计数。
相应地,S103所述根据所述物理机的能耗模型,确定所述物理机上运行的虚拟机的能耗,还具体包括:
S1035、根据所述用于计算所述第二虚拟机的能耗的所述物理机的能耗模型,确定所述物理机上运行的第二虚拟机的能耗。
其中,S1035计算第二虚拟机的能耗的方法与S1032和S1033类似,所不同的是,S1032和S1033中所述物理机能耗模型中的所述设定的参数矩阵和设定的可变能耗因子,采用S1023确定的用于计算所述第二虚拟机的能耗的物理机能耗模型中的所述设定的参数矩阵和设定的可变能耗因子计算。
本发明实施例的其他技术方案和技术效果与图1至图2所示方法相同,此处不再赘述。
图7为本发明提供的虚拟机能耗确定方法实施例四的流程图,图8为图7所示方法实施例四的第二种流程图,在图1至图6所示方法的基础上,如图7至图8所示,本发明实施例的步骤包括:
在步骤S103之后,还包括:
S104、根据所述物理机的特征信息、所述物理机的能耗模型和所述物理机的能耗,计算第一能耗偏差。
其中,可参考图8,S104可以具体包括S1041和S1042。
S1041、获取所述物理机的特征信息对应的实测能耗。
S1042、根据Pcaculate=Rtotal·(Atotal)T+a0+Pstatic计算物理机的理论能耗。
其中,Pcalculate为所述物理机的理论能耗,Rtotal中的元素R1、R2、……、Rn为所述物理机的n种特征信息,(Atotal)T中的元素a1、a2、…、an为所述物理机能耗模型中的所述设定的参数矩阵,a0为所述物理机能耗模型中的所述设定的可变能耗因子,Pstatic为所述物理机的非映射基础能耗
S1043、根据△P=Pcalculate-Pmeasure计算第一能耗偏差。
其中,△P为第一偏差能耗,Pcalculate为所述物理机的理论能耗,Pmeasure为所述物理机的实测能耗。
其中,所述第一能耗偏差可以为正值,也可以为负值。
S105、根据第一能耗偏差和第一能耗偏差分配系数,计算所述物理机上运行的虚拟机的虚拟机修正能耗,所述第一能耗偏差分配系数根据所述物理机的能耗模型确定。
S106、根据所述第一虚拟机修正能耗对所述物理机上运行的虚拟机的能耗进行第一修正。
举例来说,可以采用(Pj)′=Pj+△Pj得到修正后的所述物理机上运行的第j个虚拟机的能耗,其中,(Pj)′为修正后的所述物理机上运行的第j个虚拟机的能耗、Pj为修正前的所述物理机上运行的第j个虚拟机的能耗、△Pj为所述物理机上第j个虚拟机的虚拟机修正能耗。
需要说明的是,由于预先采集的历史特征信息数据较少,或者预先采集的历史特征信息未覆盖到物理机当前的特征信息,则预先获取的历史参数矩阵和历史可变能耗因子所对应的历史特征信息与物理机当前的特征信息的匹配程度可能存在偏差,即不能完全匹配,相应的,根据物理机当前的特征信息确定的用于计算虚拟机能耗的物理机的能耗模型中的设定的参数矩阵和设定的可变能耗因子也可能存在偏差。本发明实施例的方法将这部分能耗偏差按照各特征信息对应的能耗参数占总的物理机理论能耗的比例分配给各个虚拟机,即对虚拟机能耗进行修正,使得确定的虚拟机的能耗更准确。进一步地,对于预先获取历史参数矩阵和历史可变能耗因子数据较少的场景,也能更准确的确定虚拟机的能耗,减少了确定虚拟机能耗前的对物理机的历史特征信息的数据采集工作和根据大量历史特征信息确定历史参数矩阵和历史可变能耗因子的工作。
