Virtual machine resource allocation method and device, medium and equipment

Abstract

The invention relates to a virtual machine resource allocation method and device, a medium and equipment. The method comprises the steps that when virtual machines are created in physical machines, corresponding bare computer devices are distributed to the virtual machines, the bare computer devices are obtained by segmenting physical resources of the physical machines, and the virtual machines correspond to the bare computer devices in a one-to-one mode; then the operation mode of the bare computer equipment is configured to be a non-root mode; and the running mode of the CPU of the physical machine is switched to a non-root mode so as to start the virtual machine in the bare computer equipment. Therefore, the bare computer equipment is obtained by segmenting the physical resources of the physical machine, and the virtual machines are in one-to-one correspondence with the bare computer equipment, so that each virtual machine can run in the corresponding independent bare computer equipment, and resource isolation and performance isolation of the virtual machines are realized. In addition, the direct connection application of the virtual machine to the physical resources in the physical machine is realized, so that the overhead of hardware virtualization is effectively reduced, and the high performance of the physical machine and the virtual machine is ensured.

Description

technical field [0001] The present disclosure relates to the field of virtual technology, and in particular, to a virtual machine resource allocation method, device, medium and equipment. Background technique [0002] As computer technology develops, so does the need for virtualization. A virtual machine (Virtual Machine, VM) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Each virtual machine can be operated on the virtual machine like a physical machine, which can reduce the cost of purchasing software and hardware equipment to a certain extent, and improve the security of the physical machine system. [0003] In current virtualization technologies, a hypervisor can apply hardware virtualization extensions to provide resources to virtual machines. Although the hardware virtualization technology has reduced the number of times that the virtual machine falls into th...

Problems solved by technology

Although the hardware virtualization technology has reduced the number of times that the virtual machine falls into the virtual machine monitor, it still has a lot of extra overhead such as virtualizing the hardware, which has a great impact on the performance of the physical machine and the virtual machine
