Abstract

The present invention discloses a resource allocation method of a virtual machine and a device thereof, for improving performance of the virtual machine, and relates to the field of communication technology. The method comprises: obtaining resource allocation parameters of the virtual machine, the resource allocation parameters including scheduling parameters which is used for indicating at least two of physical processor resource, physical memory and physical input-output IO device assigned to the virtual machine to be located in the same processor node, and allocating physical resource for the virtual machine according to the resource allocation parameters. The present invention may be applied in the virtual machine technique.

Description

technical field [0001] The invention relates to the communication field, in particular to a resource allocation method and device for a virtual machine. Background technique [0002] In the cloud environment, resource allocation (mapping) refers to scheduling and allocating physical resources for virtual resources required by VM (virtual machine, virtual machine) according to the application of virtual resource requirements and the topology of existing physical resources and resource pools. , and then deploy virtual resources according to the resource scheduling result. Among them, a 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. Virtual resources can specifically include vCPU (virtual central processing unit, virtual central processing unit), vMEM (virtual memory, virtual memory), vIO (virtual Input / Output, virtual input / output) devices, etc., and p...
