用于热迁移虚拟机的方法和装置
摘要：
本申请公开了用于热迁移虚拟机的方法和装置。所述方法的一具体实施方式包括：收到将虚拟机热迁移到目的物理机的请求，则获取源物理机的CPU信息和目的物理机的CPU信息；确定源物理机的CPU指令集架构和目的物理机的CPU指令集架构是否兼容；当兼容时，则进一步确定源物理机的CPU特征和目的物理机的CPU特征是否兼容；当不兼容时，则进一步确定源物理机和所述目的物理机之间不兼容的CPU特征是否在预设的名单中；响应于确定出不兼容的CPU特征在预设的名单中，则将虚拟机从源物理机热迁移到目的物理机。该实施方式实现了异构集群下的虚拟机动态迁移问题，可以动态迁移的虚拟机不再局限在同物理CPU型号，尽可能做到较少的性能牺牲换取兼容性。
摘要（英）：

An implementation of a method for live-migrating virtual machines includes: acquiring, when receiving a request for live-migrating a virtual machine to a target physical machine, CPU information of a source physical machine and CPU information of the target physical machine; determining whether a CPU instruction set architecture of the source physical machine is compatible with a CPU instruction set architecture of the target physical machine; determining whether CPU features of the source physical machine are compatible with CPU features of the target physical machine, if the two CPU instruction set architecture are compatible; determining whether incompatible CPU features between the source physical machine and the target physical machine are in a preset list, if the two CPU instruction set architecture are not compatible; and live-migrating the virtual machine from the source physical machine to the target physical machine, in response to determining that the incompatible CPU features are in the preset list.
