Problems solved by technology

[0004] In the existing technology, DPM (Distributed Power Management, dynamic power management) will continuously integrate virtual machines into a few physical servers, which may result in live migration of some virtual machines to CPUs with high compatibility for each integration. In the end, all virtual machines are concentrated on the host where the CPU with high compatibility is located, while the host with CPU with low compatibility cannot be used, resulting in a waste of host resources

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] A virtual machine (Virtual Machine, VM) is a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. The physical host (physical server) where the existing virtual machine is located is generally divided into Three layers, the first layer is the hardwar...

Abstract

The embodiment of the invention provides a command processing method, a command processing device and a physical host of a virtual machine. The command processing method is applied to the communication field and can improve the operation success rate of the virtual machine after thermal migration between hosts of incompatible heterogeneous CPUs (Central Processing units) are located. Specifically, after a host of a source CPU of the virtual machine is thermally migrated to a host of a target CPU, if the source CPU and the target CPU are incompatible, commands which cannot be recognized by the target CPU in commands are converted into information which can be recognized by the target CPU, the information which can be recognized by the target CPU is transmitted to the target CPU to facilitate the execution of the target CPU.

Description

technical field [0001] The present invention relates to the communication field, in particular to a virtual machine instruction processing method, device and physical host. Background technique [0002] Cloud computing is a computing method that has emerged in recent years. It abstracts all computers into specific computing resources, and then provides these computing resources to users, instead of directly providing one or more computers as before. Server virtualization technology is a key technology based on the infrastructure layer in cloud computing. By virtualizing physical servers, multiple virtual machines (virtual operating systems) can be deployed on a single physical node to improve resource utilization of physical servers and reduce usage costs. [0003] An important technology of server virtualization technology is DRS (Distributed Resource Scheduler, dynamic resource scheduling) technology: the cluster management system regularly monitors the resource utilizati...
