    • A method, information processing system, and computer program product manage virtual machine migration. A virtual machine is selected from a set of virtual machines. Each physical machine in a plurality of physical machines is analyzed with respect to a first set of migration constraints associated with the virtual machine that has been selected. A set of physical machines in the plurality of physical machines that satisfy the first set of migration constraints is identified. A migration impact factor is determined for each physical machine in the set of physical machines that has been identified based on a second set of migration constraints associated with the virtual machine that has been selected. A physical machine is selected from the set of physical machines with at least a lowest migration impact factor on which to migrate the virtual machine that has been selected in response to determining the migration impact factor.
    • 一种方法,信息处理系统和计算机程序产品管理虚拟机迁移。 从一组虚拟机中选择虚拟机。 关于与已经选择的虚拟机相关联的第一组迁移约束来分析多个物理机器中的每个物理机器。 识别满足第一组迁移约束的多个物理机器中的一组物理机器。 基于与已经选择的虚拟机相关联的第二组迁移约束已经识别的物理机组中的每个物理机器确定了迁移影响因子。 从具有至少最小的迁移影响因素的物理机组中选择物理机器,以便迁移根据确定迁移影响因子而选择的虚拟机。

    • A network-centric modeling mechanism is provided for updating network models in order to mitigate network issues. The network-centric modeling mechanism determines for each component in a plurality of components whether a system parameter in a set of parameters particular to the component has deviated from a predicted system parameter value in a set of predicted system parameter values past a predetermined threshold. Responsive to the system parameter deviating from the predicted system parameter value past the predetermined threshold, the network-centric modeling mechanism generates an event stream indicating a sufficient deviation. The network-centric modeling mechanism determines whether the event stream matches a previous pattern. Responsive to identifying the previous pattern that matches the event stream, the network-centric modeling mechanism preemptively mitigates any related issues in the component or in a related component in the plurality of components using topology-aware indices associated with the previous pattern.
    • 提供以网络为中心的建模机制,用于更新网络模型以减轻网络问题。 以网络为中心的建模机制确定多个组件中的每个组件,特定于组件的一组参数中的系统参数是否偏离预定系统参数值的预测系统参数值超过预定阈值。 响应于偏离超过预定阈值的预测系统参数值的系统参数,以网络为中心的建模机制产生指示足够偏差的事件流。 以网络为中心的建模机制确定事件流是否匹配先前的模式。 响应于识别与事件流匹配的先前模式,以网络为中心的建模机制使用与先前模式相关联的拓扑感知索引,先预先减轻组件中或组件中相关组件中的任何相关问题。
