Process migration tracking method based on multi-core platform virtual machine

Abstract

The invention relates to a process migration tracking method, in particular to a process migration tracking method in a client operating system of a virtual machine based on a multi-core platform. By tracking process migration as a target, through twice mapping, the method spans a monitor of the virtual machine to monitor a relation between a process and a physical processor inner core in the client operating system. The method comprises the following steps: firstly, finding out a running environment of each process in the client operating system, and extracting information associated with theprocessor from the running environment; secondly, starting from the inner core of the client operating system, transmitting the relation between each process and a virtual processor number to the monitor of the virtual machine through a communication mechanism; and finally, in the monitor of the virtual machine, acquiring a mapping relation between the virtual processor number and the number of the physical processor inner core so as to map the process in the client operating system to the physical processor inner core, and repeating the process, continuously acquiring the corresponding information of each moment, namely spanning the monitor of the virtual machine to associate the client operating system and the physical processor inner core so as to achieve the aim of tracking the migration process of the client operating system between the physical processor inner cores.

Description

technical field [0001] The invention relates to a tracking method for process migration based on a virtual machine, in particular to a tracking method for process migration in a virtual machine guest operating system based on a multi-core platform. Background technique [0002] With the advancement of hardware technology, multi-core processors are becoming more and more popular and cheaper. As the two most important processor manufacturers in the world, Intel and AMD released 4-core processors for ordinary users respectively. At the same time, as a broad concept, virtualization describes an abstraction of computer resources. It can be understood as a framework or theory that divides computer resources into multiple computing environments that can be executed independently. On the virtual machine monitor (Virtual Machines Monitor-VMM) or virtual environment (Virtual Environments-VEs) is divided and created. However, both multi-core processors and virtualization technology h...

However, none of these tools can pay attention to how to reflect the relationship between the process and the processor core it runs on, monitor the migration process of the process on the processor core, let alone cross the level of the virtual machine monitor to reflect the relationship between the guest operating system. The mapping relationship between the process and the physical core of the processor and the migration process
