Embodiment 1

[0039] In order to solve the technical problems existing in the prior art, the embodiment of the present invention provides a method for communication between virtual machine monitor partitions.

[0040] figure 1 Shows a schematic flowchart of a communication method between virtual machine monitor partitions according to an embodiment of the present invention; figure 2 A concrete modular schematic diagram of a communication method between partitions of a virtual machine monitor in an embodiment of the present invention is shown; reference figure 1 with figure 2 As shown, the method for communication between virtual machine monitor partitions in the embodiment of the present invention includes the following steps.

[0041] Step S101: When all the partitions controlled by the virtual machine monitor are in the initial state, all the partitions controlled by the virtual machine monitor respectively perform preset calculations on the key node configuration files of their own systems, a...

Embodiment 2

[0058] In order to solve the technical problems existing in the prior art, an embodiment of the present invention provides a communication device between virtual machine monitor partitions.

[0059] image 3 Shows a schematic structural diagram of a communication device between virtual machine monitor partitions in the second embodiment of the present invention; reference image 3 As shown, the communication device between virtual machine monitor partitions in the embodiment of the present invention includes a communication request sending module, a preset value calculation storage module, a safe preset value storage module, and a comparison module that are sequentially connected.

[0060] The communication request sending module is used for the communication initiating zone to send the communication request to the communication receiving zone through the right item manager;

[0061] The preset value calculation storage module is used to perform preset calculation on the key node conf...

Embodiment 3

[0066] In order to solve the above technical problems in the prior art, an embodiment of the present invention also provides a storage medium, which stores a computer program.

Abstract

The invention discloses an inter-partition communication method and device for a virtual machine monitor, a storage medium and a terminal. The method comprises the steps that a communication initiating partition sends a communication request to a communication receiving partition through a right item manager; after receiving the communication request, the communication receiving partition performspreset operation on a key node configuration file of a system of the communication receiving partition, and sends a preset value obtained by the operation to a first register of the right item manager; the right item manager loads a security preset value corresponding to the communication receiving partition in a local log file according to the communication request, and stores the security preset value in a second register of the right item manager; and whether the preset value in the first register is the same as the safety preset value in the second register is judged. According to the method and the device, communication security management among the partitions is converted into access permission management on a shared memory, so the communication of each partition is decoupled, and the stored security preset values are encrypted to ensure information security.

Description

Technical field [0001] The present invention relates to the technical field of embedded virtual machine monitoring platforms, in particular to a method and device, storage medium and terminal for communication between virtual machine monitor partitions. Background technique [0002] Hypervisor, also called Virtual Machine Monitor, is an intermediate software layer that runs between the physical server and the operating system, allowing multiple operating systems and applications to share a set of basic physical hardware to coordinate access to the server All of the physical devices and virtual machines can be regarded as the "meta" operating system in the virtual environment. Hypervisor is the core of all virtualization technologies. When the server starts and executes the Hypervisor, it allocates an appropriate amount of memory, CPU, network, and disk to each virtual machine, and loads the guest operating system of all virtual machines. [0003] At present, the application of emb...
