    • PURPOSE: A method for recovering lock holder preemption in a virtual machine system and an apparatus thereof are provided to sense lock holder preemption (LHP) in a virtual machine (VM) easily, and to solve LHP through scheduling technique. CONSTITUTION: Operation state information and lock information of an operating system (OS) are acquired in the operation of a virtual machine including a virtual CPU (vCPU) and an OS driving the virtual CPU in an acquisition step (510). It is judged whether vCPU is in lock holder preemption (LHP) state or not on the basis of the operation state information and the lock information, in a judgment step (520). [Reference numerals] (510) Acquire operation state information of vCPU and lock information of an operating system; (520) Judge whether vCPU is in lock holder preemption (LHP) state or not on the basis of the vCPU information and the lock information; (530) Is LHP generated?; (540) Transfer the calculation performed by vCPU to other pCPU; (AA) Start; (BB) End
    • 目的:提供一种用于恢复虚拟机系统中的锁持有人抢占的方法及其装置,用于容易地感知虚拟机(VM)中的锁持有人抢占(LHP),并通过调度技术解决LHP。 构成:在采集步骤(510)中,在包括虚拟CPU(vCPU)和驱动虚拟CPU的OS的虚拟机的操作中获取操作系统(OS)的操作状态信息和锁定信息。 在判断步骤(520)中,基于操作状态信息和锁定信息判断vCPU是否处于锁定保持器抢占(LHP)状态。 (附图标记)(510)获取vCPU的操作状态信息和操作系统的锁定信息; (520)根据vCPU信息和锁定信息判断vCPU是否处于锁持有人抢占(LHP)状态; (530)是否产生LHP? (540)将vCPU执行的计算转移到其他pCPU; (AA)开始; (BB)结束
