[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0021] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a method for changing virtual machine attributes according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0022] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the virtual machine attribute change method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0023] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0024] In this embodiment, a method for changing virtual machine attributes is provided. Figure 2 As shown, the following steps are included:

[0025] Step S202, creating a shared directory on the host where the virtual machine is located, wherein the shared directory records the attribute configuration file of the virtual machine;

[0026] Step S204, when the virtual machine is started, controlling the virtual machine to access the attribute configuration file in the shared directory;

[0027] Step S206, modifying the attribute data in the virtual machine according to the attribute configuration file to obtain a virtual machine with changed attributes.

[0028] Through the above steps, in the process of configuring the virtual machine properties, a shared directory can be created so that the virtual machine can automatically call the property configuration file in the shared directory to configure the virtual machine properties, thereby achieving the effect of automatically configuring the virtual machine properties. Moreover, since the shared directory can be called by multiple virtual machines together, the efficiency of the virtual machine property configuration can be improved, solving the problem of low efficiency of virtual machine property configuration.

[0029] As an example, creating a shared directory on the host where the virtual machine resides includes:

[0030] Create different types of subdirectories in the shared directory. Different types of subdirectories are used to record different attribute configuration files.

[0031] Set up different property configuration files for different types of subdirectories.

[0032] As an example, when a virtual machine is started, the property configuration file for controlling the virtual machine to access a shared directory includes:

[0033] Determine the type of attribute to be changed for the virtual machine;

[0034] Controls virtual machine access to property configuration files in subdirectories that match the property type.

[0035] As an example, when a virtual machine is started, the property configuration file for controlling the virtual machine to access a shared directory includes:

[0036] In the case where the virtual machine includes multiple virtual machines, controlling multiple virtual machines to access the same property configuration file; or

[0037] In the case that the virtual machine includes multiple virtual machines, each of the multiple virtual machines is controlled to access a property configuration file.

[0038] As an example, when a virtual machine is started, the property configuration file for controlling the virtual machine to access a shared directory includes:

[0039] Control the virtual machine to read data in the property configuration file; or

[0040] The control virtual machine writes data to the property configuration file.

[0041] As an example, after creating a shared directory on the host where the virtual machine is located, the method further includes:

[0042] Receive control instructions, where the control instructions are used to add / delete / check / modify the shared directory;

[0043] Respond to control instructions and perform add / delete / query / modify operations on shared directories.

[0044] Optionally, the virtual machine in the embodiment of the present application may be a virtual machine running different systems. For example, a virtual machine running a Microsoft system, an Android system, etc. A virtual machine running an Android system is referred to as an Android virtual machine, and the Android virtual machine is used as an example for description.

[0045] The terminal where the Android virtual machine is located can be called the host. First, create a shared directory on the host; then, based on the existing configuration of the Android virtual machine (hereinafter referred to as the virtual machine), add the host shared directory related configuration in the Android virtual machine configuration file; finally, mount the host shared directory when the Android virtual machine starts. The Android virtual machine automatically configures the Android system properties by reading the content in the host shared directory. This can be done in the Android image. Therefore, the Android virtual machines created in batches based on this image have this function, and the property information has been modified, realizing the effect of batch modifying the properties of the Android virtual machines.

[0046] The use of shared directories is relatively flexible. You can mount multiple virtual machines on the same shared directory according to project needs, or mount each virtual machine separately. The mount permissions can be set to read-only, read-write, etc.

[0047] To modify the properties of each Android virtual machine in batches, you can modify the property configuration file in the host shared directory through a program or script, and then restart the Android virtual machine. This method avoids the tedious operation of modifying the properties of virtual machines one by one, saves time and improves usage efficiency.

[0048] Figure 3 This is the system structure diagram. Figure 3 In the example, the virtual machine runs on the host; after the created virtual machine is installed with the Android operating system, the Android virtual machine realizes some functions of the mobile phone, such as screenshots, games, etc.; conf.xml represents the configuration file of the virtual machine; the shared directory is a directory on the host, which is mainly used to realize data interaction between the host and the virtual machine; / etc / init.sh inside the Android virtual machine is the script executed when the Android virtual machine starts.

[0049] Figure 4 This is a schematic diagram of the principle flow of the system and method, the specific contents are as follows:

[0050] S401: Create a shared directory on the host. In order to meet the user's demand for diversified and multi-specification Android virtual machines, a series of sub-directories can be created under the shared directory to store the property configuration files of the virtual machines. The properties can be set through programs, scripts, or manually, and the property values ​​of different virtual machines can be kept different.

[0051] S402: Adding the configuration related to the shared directory to the configuration file conf.xml of the virtual machine indicates that the virtual machine has the ability to mount the shared directory of the host;

[0052] S403: For the situation where each virtual machine mounts an independent shared directory, it is necessary to add the property configuration files of each virtual machine in each subdirectory under the host shared directory, and use the MAC address as the unique identifier, that is, the MAC address of the virtual machine network card is used as the subdirectory name under the host shared directory, and the property configuration files of different virtual machines are stored in different subdirectories, thereby realizing a one-to-one correspondence between the virtual machine and the property configuration file; for the situation where multiple virtual machines jointly mount a host shared directory, each virtual machine can read the common configuration file under the specified mounting directory.

[0053] When starting the Android virtual machine, S404: add a step of mounting the host shared directory in the Android startup script / etc / init.sh to ensure that the host shared directory is automatically mounted when the Android system starts. Timeout protection can be added, that is, the virtual machine can still be started after the mounting fails, and does not affect user use; in the case of mounting failure, the Android virtual machine attribute value is not modified, and in the case of mounting success, the Android virtual machine attribute value is modified.

[0054] S405: In the Android startup script / etc / init.sh, a step of reading a specified configuration file in a shared directory is added, and the attribute value in the configuration file is written into the Android system, so that parameter protection can be added, that is, the attribute value is set only when the read attribute value is different from the current value, thereby improving the use efficiency;

[0055] S406: After the Android system is started, the entire property configuration process is completed.
