Abstract

The invention provides a virtual machine memory management method and equipment. The method comprises the following steps: identifying a non-operating system memory of a virtual machine from total memory allocated to the virtual machine; wherein the total memory comprises the memory of the virtual machine and the management memory of the virtual machine monitor; wherein the memory of the virtual machine comprises the memory of an operating system of the virtual machine and the memory of a non-operating system of the virtual machine; taking a memory of a non-operating system of the virtual machine as an exchangeable memory; and storing the data in the exchangeable memory into a nonvolatile memory. The problem of obvious reduction of the performance of the computer in an excessive submissionscene of the virtual machine can be avoided, the running stability of the virtual machine is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of virtual machines, in particular to a method and device for virtual machine memory management. Background technique [0002] Virtualization technology is the core technology of cloud scenarios. In a system deployed with multiple virtual machines (Virtual Machine, VM), multiple virtual machines share the physical resources of the same physical host (Physical Machine, PM), such as processors, memory, disk and network devices, etc. In this way, the physical resources of one physical host can be shared with multiple users at the granularity of VM, so that multiple users can use physical resources conveniently and flexibly under the premise of security isolation, and greatly improve the utilization rate of physical resources. [0003] In virtualization technology, the memory allocated to each virtual machine is fixed. In a cloud computing platform, no matter from the perspective of a virtual machine...
