Virtual machine resource allocation method, device and device, and readable storage medium

Abstract

The invention discloses a virtual machine resource allocation method, which comprises the steps of obtaining and analyzing a creation instruction for creating a target virtual machine to obtain resource application information; according to the CPU application number in the resource application information, obtaining a plurality of reserved CPUs applied by the CPUs from the CPU reservation area, and adjusting the reserved CPUs to be target CPUs; allocating a target memory to the target virtual machine according to the resource application information, and operating the target virtual machine by using the target CPU and the target memory; according to the method, the fixed target CPUs are allocated to the newly created target virtual machine for running, so that the virtual machine can be prevented from being switched among the CPUs during running, context switching in the CPU switching process is avoided. Meanwhile, interference of critical noise in the switching process is avoided, and the performance of the whole virtual machine is improved; in addition, the invention also provides a virtual machine resource allocation device and equipment and a computer readable storage medium,which also have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of virtual machines, and in particular to a virtual machine resource allocation method, a virtual machine resource allocation device, a virtual machine resource allocation device, and a computer-readable storage medium. Background technique [0002] A virtual machine (Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Everything that can be done on a physical computer can be done on a virtual machine. When creating a virtual machine on a computer, part of the hard disk and memory capacity of the physical machine needs to be used as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent CMOS, hard disk and operating system, and the virtual machine can be operated like a physical machine. The existing technology uses time-division multip...
