Abstract

The invention provides a method and a device for realizing multi-core scheduling of a virtual machine. The method comprises the following steps: correspondingly configuring a main virtual machine of the virtual machine and N1 shadow virtual machines to N CPU cores; scheduling the main virtual machine and the shadow virtual machine to run on the corresponding CPU cores in the same time window through a time scheduling table, wherein the time scheduling table is configured with a time window for scheduling the operation of the main virtual machine and the shadow virtual machine. Based on the method, the CPU resource utilization rate and the real-time performance of the virtual machine can be better coordinated.

Description

technical field [0001] The present application relates to the field of virtual machines, in particular to a method and device for realizing multi-core scheduling of virtual machines. Background technique [0002] Virtual machine technology appeared in the 1960s and 1970s and was mainly used on mainframes. Generally, the virtual machine technology refers to a system-level virtualization technology, and the virtualization software in the system-level virtualization technology is called a virtual machine monitor (Virtual Machine Monitor, VMM), which targets a virtual instruction system architecture. The core of system-level virtualization technology is to build a virtual machine monitor, and then create a virtual machine on it, and run the operating system that originally runs directly on the actual hardware platform in the virtual machine. Through the virtual machine monitor, multiple virtual machines can be run on a single physical machine, and each virtual machine can suppo...
