[0030] First, some nouns or terms that appear in the process of describing the embodiments of the present disclosure are subject to the following explanations:

[0031] Hypervisor: Also known as a virtual machine monitor (English: virtual machine monitor, abbreviated as VMM), is the software, firmware or hardware used to create and execute virtual machines.

[0032] The computer used by the hypervisor to execute one or more virtual machines is called the host machine, and these virtual machines are called guest machines. The hypervisor provides a virtual operating platform to execute guest operating systems and is responsible for managing the execution phase of other guest operating systems; these guest operating systems share virtualized hardware resources.

[0035] QEMU: QEMU is a set of processor simulation software that distributes source code under the GPL license and is widely used on the GNU / Linux platform.

[0036] Example 1

[0037] According to an embodiment of the present application, a method embodiment of a storage space management method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] The car system in the related technology is usually composed of multiple systems, and each system in the multiple systems runs separately in a virtual machine. Taking the multi-system car system with Hypervisor architecture as an example, the Hypervisor architecture refers to running multiple virtual machines on an underlying operating system (such as Linux), and each virtual machine runs its own operating system, such as Android or AGL. The effect in the actual car can be understood as having multiple screens. During operation, the car system projects the AGL virtual machine display part to the instrument, and displays the virtual machine running the operating system with specific functions on the screen in the middle of the car, etc. However, these are actually running on an underlying operating system (such as the underlying Linux operating system), and each virtual machine can only display to the user through the interactive interface The storage space information of the storage space allocated by the virtual machine itself, that is, only the storage space of the system operating system with specific functions of the virtual machine itself can be controlled. However, sometimes users need to know the total size of the storage space actually available in the current vehicle, as well as the current size of the available storage space of each running virtual machine, or need to clean up the storage space corresponding to multiple virtual machines. At this time, since each virtual machine in the relevant technology can only control its own corresponding storage space, the user needs to manually issue corresponding control instructions to each virtual machine through the interactive interface corresponding to each virtual machine, which takes a long time. In addition, the operating systems running in some virtual machines do not have corresponding interactive interfaces displayed to users. At this time, users cannot control the storage space corresponding to these virtual machines, such as querying the size of available storage space or cleaning up storage space.

[0039] The examples provided in the present application are as follows Figure 1 The storage space management method shown can solve the above problem and achieve the management and control of the storage space corresponding to other virtual machines through one virtual machine.

[0040] Figure 1 A storage space management method according to an embodiment of the present invention is applicable to an electronic device running multiple virtual machines, such as Figure 1 As shown, the method comprises the following steps:

[0041] Step S102, receiving a storage space management instruction sent by a first target virtual machine, wherein the first target virtual machine is any one of the multiple virtual machines;

[0042] In the technical solution provided in step S102, the first target virtual machine may be a virtual machine having an interactive interface that can interact with the user, such as a virtual machine running a vehicle central control system, or may be a virtual machine without an interactive interface with the user. When the first target virtual machine is a virtual machine with an interactive interface, the storage space management instruction may be an instruction generated by the first target virtual machine based on the operation information input by the user through the interactive interface. When the first target virtual machine is a virtual machine with an interactive interface or without an interactive interface, the storage space management instruction may be an instruction generated by the operation rules that are expected to be pre-set by the target virtual machine.

[0043] Specifically, when the first target virtual machine generates a storage space management instruction based on the operation information input by the user through the interactive interface, the storage space management program in the first target virtual machine determines the operation that the user wants to perform based on the operation information and generates a corresponding space management instruction. For example, when the user wants to query the current available storage space of each virtual machine, the generated space management instruction is a storage space query instruction. When the user wants to clean up the storage space corresponding to each virtual machine, the generated space management instruction is a storage space cleanup instruction.

[0044] When the first target virtual machine generates a storage space instruction according to a preset operation rule, the storage space management program in the first target virtual machine will determine the generation time point and instruction type of the storage space instruction according to the operation rule. For example, the available storage space corresponding to each virtual machine can be obtained at regular intervals or at each fixed time point according to the operation rule, or the storage space corresponding to each virtual machine can be cleared.

[0045] In addition, as an optional implementation, when the first target virtual machine generates storage space instructions according to the operation rules, it can generate multiple different types of storage space instructions. For example, when the operation rules are to periodically obtain the available storage space size corresponding to each virtual machine, and clean up the data in the storage space when the available storage space is less than a preset threshold, then the first target virtual machine can first generate a storage space query instruction, and then determine the virtual machines that need to clean up the storage space according to the available storage space size fed back by each virtual machine, and send storage space cleanup instructions to these virtual machines.

[0046] Step S104, determining storage space information corresponding to a second target virtual machine according to the storage space management instruction, wherein the second target virtual machine is any one of the multiple virtual machines except the first target virtual machine;

[0047] In the technical solution provided in step S104, when the storage space management instruction is a storage space query instruction, the storage space information corresponding to the second target virtual machine determined according to the storage space management instruction is the size of the currently remaining available storage space of the second target virtual machine. When the storage space management instruction is a storage space cleanup instruction, the storage space information determined according to the storage space management instruction is the size of the available storage space of the second target virtual machine before and after the storage space is cleaned up.

[0048] In addition, in some embodiments of the present application, the second target virtual machine may be a virtual machine without a corresponding interactive interface.

[0049] Step S106: sending storage space information to the first target virtual machine.

[0050] By receiving a storage space management instruction sent by a first target virtual machine, wherein the first target virtual machine is any one of a plurality of virtual machines; determining storage space information corresponding to a second target virtual machine according to the storage space management instruction, wherein the second target virtual machine is any one of the plurality of virtual machines except the first target virtual machine; and sending storage space information to the first target virtual machine, by determining the storage space information corresponding to the second target virtual machine according to the storage space management instruction sent by the first target virtual machine, the purpose of obtaining the storage space information corresponding to the second target virtual machine through the first target virtual machine is achieved, thereby realizing the technical effect of managing the storage space of other virtual machines through one virtual machine, and further solving the technical problem in the related art that it takes too long to process the operating status of multiple virtual machines due to the inability to issue control instructions to other virtual machines through one virtual machine.

[0051] In some embodiments of the present application, in order to solve the technical problem that different virtual machines cannot communicate directly, the present application provides a storage space management system as shown. Figure 2 This is the architecture diagram of the storage space management system. Figure 2 It can be seen that the storage space management system includes multiple qemu-type virtual machines, each of which runs a corresponding operating system, and the type of the operating system can be Android or AGL instrument, etc. In addition, each virtual machine also includes a virtio interface, so that the storage space control service module running in the underlying operating system in the storage space management system can communicate with each virtual machine through the virtio interface, wherein the system kernel of the underlying operating system can be the linux kernel.

[0052] In addition, from Figure 2It can be seen that the storage space management module is also connected to the memory in the electronic device, so that each virtual machine can manage its corresponding storage space through the storage space management module.

[0053] pass Figure 2 The storage space management system and Figure 1 The storage space management method provided in solves the problem that applications in virtual machines cannot obtain the correct total space size and available space size through the Android native interface under the Hypervisor architecture. It can manage and control the storage space of a single virtual machine, as well as the storage space of all virtual machines as a whole, and enable applications in a certain virtual machine to understand and manage the space size of other virtual machines, preventing programs in electronic devices from running abnormally due to insufficient storage space.

[0054] In the technical solution provided in the above step S104, when the storage space management instruction is a storage space query instruction, determining the storage space information corresponding to the second target virtual machine based on the storage space management instruction includes: when the storage space management instruction is a storage space query instruction, generating a target storage space query instruction, wherein the target storage space query instruction is a query instruction for querying the storage space information corresponding to the second target virtual machine, and the storage space information includes at least the current available storage space size corresponding to the second target virtual machine; sending the target storage space management instruction to the second target virtual machine; and obtaining the storage space information sent by the second target virtual machine.

[0055] Specifically, when querying the available storage space size corresponding to each virtual machine in the electronic device, the actions performed by each virtual machine and the storage space management module in the electronic device are as follows: Figure 3 As shown, the following steps are included:

[0056] Step S302, the application in the first target virtual machine generates a storage space query instruction;

[0057] Step S304, the first target virtual machine sends a storage space query instruction to the storage space management module;

[0058] Step S306: the storage space management module sends a query request to the second target virtual machine according to the storage space query instruction to obtain the current actual available storage space size of each virtual machine;

[0059] Step S308, the storage space management module summarizes the current actual available storage space sizes corresponding to each second target virtual machine and sends the sum to the first target virtual machine;

[0060] Step S310: The first target virtual machine displays the current actual available storage space size corresponding to the first target virtual machine and the current actual available storage space size corresponding to each second target virtual machine to the user.

[0061] When the storage space management instruction is a storage space cleaning instruction, determining the storage space information corresponding to the second target virtual machine based on the storage space management instruction includes: when the storage space management instruction is a storage space cleaning instruction, generating a target storage space cleaning instruction, wherein the target storage space cleaning instruction is used to instruct the second target virtual machine to clean up target data in the storage space corresponding to the second target virtual machine; cleaning up the target data according to the target storage space cleaning instruction; receiving the storage space information sent by the second target virtual machine, wherein the storage space information includes first storage space information generated by the second target virtual machine based on the current available storage space size after cleaning up the target data, and target storage space information generated by the second target virtual machine based on the current available storage space size before cleaning up the target data.

[0062] As an optional implementation, when cleaning target data according to a target storage space cleaning instruction, the following steps are included: sending the target storage space cleaning instruction to the second target virtual machine; obtaining a data cleaning service call instruction sent by the second target virtual machine, wherein the data cleaning service call instruction is an instruction generated after the second target virtual machine receives the target storage space cleaning instruction; and based on the data cleaning service call instruction, calling a corresponding data cleaning module to clean the target data.

[0063] In addition, since different virtual machines run different system types, the storage space cleaning tools used when cleaning storage space are also different. Therefore, based on the data cleaning service calling instruction, calling the corresponding data cleaning module to clean the target data includes: determining the system information indicated by the data cleaning service calling instruction, wherein the system information includes the system type information of the system running in the second target virtual machine; calling the data cleaning service corresponding to the system information to clean the target data.

[0064] Specifically, when cleaning up the storage space corresponding to each virtual machine in the electronic device, the actions performed by each virtual machine and the storage space management module in the electronic device are as follows: Figure 4 As shown, the following steps are included:

[0065] Step S402, the application in the first target virtual machine generates a storage space cleanup instruction;

[0066] Step S404, the first target virtual machine sends a storage space cleanup instruction to the storage space management module;

[0067] Step S406, the storage space management module sends a cleanup request to the second target virtual machine according to the storage space cleanup instruction;

[0068] Step S408, after receiving the cleanup request, the second target virtual machine calls a space cleanup program corresponding to the system type in the virtual machine to clean up the storage space, and sends the cleanup result to the storage space management module, wherein the cleanup result includes the available storage space size of each second target virtual machine before and after the cleanup;

[0069] Step S410, the storage space management module summarizes the cleaning results corresponding to each second target virtual machine and sends them to the first target virtual machine;

[0070] Step S412: The first target virtual machine displays the current actual available storage space size corresponding to the first target virtual machine and the current actual available storage space size corresponding to each second target virtual machine to the user.
