Abstract

The invention discloses a method for enabling a qemu-kvm virtual machine to execute any command, and a storage medium. The method comprises the steps of adding an interface in a qemu-guest-agent format to a system capable of compiling a source code; calling the interface in the qemu-guest-agent format by a host machine, and inputting a to-be-executed command and command parameters; transmitting the command and the command parameters into the virtual machine through a qemu-guest-agent communication mechanism in the virtual machine; obtaining the command and the command parameters by a qemu-geust-agent daemon process in the virtual machine; executing the command in the virtual machine; and judging whether the command is returned successfully or not. According to the technical scheme, complete control of the host machine to the virtual machine and personalized customization of the virtual machine are realized; the virtual machine is enabled to execute any internal command; and convenienceand quickness are achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and a storage medium for enabling a qemu-kvm virtual machine to execute arbitrary commands. Background technique [0002] Among the qemu-guest-agent injection methods implemented by the current qemu-kvm virtual machine, there are only a few injection methods. When using any of the injection methods on the host machine, the qemu-guest-agent daemon process inside the virtual machine can only implement a corresponding function, which is equivalent to only executing a corresponding fixed command inside the virtual machine. That is, an injection method corresponds to a fixed command, and the host machine cannot directly allow the virtual machine to complete any command, and it is impossible to realize complete control of the virtual machine and personalized customization of the virtual machine conveniently and quickly. [0003] Among the current injection methods, the more...
