A method, device and physical machine for processing sensitive instructions

Abstract

The embodiment of the invention relates to the field of computer virtualization. According to the embodiment of the invention, after a virtual machine handles a to-be-handled sensitive instruction and is trapped, a memory address to which the to-be-handled sensitive instruction corresponds can be acquired; when the memory address to which the to-be-handled sensitive instruction corresponds is the same as a memory address to which a centralized initial instruction of a saved arbitrary sensitive instruction corresponds, a sensitive instruction set including the initial instruction having the same corresponding memory address as the to-be-handled sensitive instruction can be acquired; the sensitive instruction set can be handled according to the acquired instructions recorded in the sensitive instruction set and the execution sequence of the instructions, so that the frequency of the virtual machine being trapped is reduced, and the performance of the virtual machine is improved.

Description

technical field [0001] The invention relates to the field of computer virtualization, in particular to a method, device and physical machine for processing sensitive instructions. Background technique [0002] In the field of virtualization, virtualization technology expands the capacity of hardware, simplifies the reconfiguration process of software, realizes the virtualization of multiple virtual machines on a physical host, and runs an independent operating system on each virtual machine at the same time , thereby significantly improving the work efficiency of the computer, wherein these independent operating systems are called guest operating systems (Guest Operating System, Guest OS). [0003] In the prior art, hardware virtualization technology is usually used to access processors. In the virtual machine system under the Xen framework, Xen is a virtual machine monitor, and the virtual machine cannot process sensitive instructions, for example, some of the instructions...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, whenever a virtual machine executes a sensitive instruction, it needs to process a sensitive instruction in a virtual machine trap

When there are continuous sensitive instruction accesses, the virtual machine needs to execute a large number of sensitive instructions in a short period of time, causing a large number of virtual machines to be trapped and degrading the performance of the virtual machine
