Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a virtual machine starting method, including:
determining a first starting configuration file, wherein the first starting configuration file is a pre-stored file, the first starting configuration file comprises a plurality of execution results, and the execution results are correspondingly generated in the starting process of the virtual machine based on the boot process;
and finishing the creation and the starting of the virtual machine based on the first starting configuration file and the boot process.
For example, the electronic device is loaded with a virtual machine emulator software/program, which is an open source simulation processing software, such as qemu (quick emulator), and when the software is loaded in the electronic device, a virtual emulation module is generated for completing the start of the virtual machine, which is hereinafter referred to as a virtual machine emulator. After a user starts the virtual machine simulator and inputs a virtual machine creating instruction to the virtual machine simulator, the virtual machine simulator can determine whether a first starting configuration file is stored in a storage module of the virtual machine simulator, a plurality of execution results are stored in the first starting configuration file, and the plurality of execution results are correspondingly generated by the virtual machine simulator in the process of sequentially executing a guide flow to complete the creation and starting processes of the historical virtual machine. That is, the boot flow includes a plurality of boot steps, and when the virtual machine emulator executes the plurality of boot steps in sequence, an execution result is generated based on each boot step, and a next boot step needs to be executed after a previous boot step completes execution and generates a corresponding execution result. That is, the execution result of the previous boot step is a trigger condition for executing the next boot step. When the virtual machine simulator determines that a first starting configuration file is stored in the storage module of the virtual machine simulator or other storage modules of the electronic equipment, the virtual machine simulator at least completes the creation and starting of the virtual machine at this time together based on the first starting configuration file and the boot process. Or, when a user wants to start a certain historical virtual machine, the user may determine a first start configuration file corresponding to the historical virtual machine to be started, and then the device completes the start of the historical virtual machine based on the first start configuration file and the boot flow. Because the first start configuration file stores part or all of the execution results required in the starting process of the virtual machine, when the virtual machine simulator starts the virtual machine based on the boot flow, or the virtual machine is created and started, the execution results in the first start configuration file can be directly used, so that the processing results of at least part of the boot steps are not required to be deduced in the starting, or the creating and starting processes of the virtual machine, the starting time of the virtual machine is at least saved, the actual boot process is simplified, a large amount of intermediate redundant data generated when each processing result is deduced is avoided, the data processing load is reduced for the electronic equipment, and the response speed of the electronic equipment to a user is accelerated.
Therefore, based on the disclosure of the above embodiments, the embodiments of the present application have the beneficial effects that the execution results correspondingly generated in the process of creating and starting the virtual machine in the history are stored to assist the virtual machine simulator to create and start again based on the boot flow, or start the virtual machine again, so that in the process of starting the virtual machine this time, the execution results of at least part of the boot steps do not need to be processed and derived again, but can be directly called for the stored execution results, so that the processing and deriving processes of at least part of the execution results can be reduced, the processing and deriving time is saved, the processing load of the device is reduced, the starting time of the virtual machine is shortened, and the virtual machine is quickly started.
Further, as shown in fig. 2, the boot flow in this embodiment includes the following steps:
starting a virtual machine simulator;
creating a virtual main board and a virtual memory according to the obtained first virtual machine configuration information;
initializing a virtual mainboard;
establishing a storage space mapping relation between virtual hardware in a virtual mainboard and a virtual memory;
determining a target operating system according to the configuration information of the first virtual machine, and guiding the target operating system;
controlling a target virtual main board to load a kernel of a target operating system;
and starting the daemon of the target operating system.
The first virtual machine configuration information is input based on a dialog bar or the like for inquiring specific virtual hardware configuration fed back by the virtual machine emulator after the user inputs a virtual machine creation instruction, and may also be input by the user while inputting the virtual machine creation instruction, which is not limited specifically. The first virtual machine configuration information specifically includes configuration parameters of each virtual hardware in the first virtual machine, such as a model number of a virtual motherboard, a size of a virtual hard disk, and the like, and may also include a specified loaded virtual operating system, that is, a target operating system in the text, such as a loaded windows operating system, a linux operating system, and the like. Initializing the virtual motherboard includes starting a Sea BIOS program (SeaBIOS is an open source 16bit x86 BIOS program), and completing initialization of the memory, the central processing unit, and the input/output system on the virtual motherboard. The daemon for starting the target operating system may be, for example, a program for starting a firewall, installing a driver of virtual hardware, and the like, and of course, while the daemon is started, a client application, such as a browser, and the like, may also be started. The execution results are correspondingly generated when the virtual machine emulator executes the boot steps, and the execution results also include the already established virtual machine, that is, the execution results of the virtual main board and the virtual memory are created according to the first virtual machine configuration information. When the same virtual machine is started again, the execution result of the corresponding virtual machine can be directly called.
Further, when determining the first boot configuration file, the virtual machine emulator in this embodiment includes:
determining that a starting configuration file is stored;
determining the file content of the starting configuration file;
and determining a first starting configuration file containing an execution result required for starting the virtual machine at this time from the starting configuration files at least based on the file content.
That is, in the process of determining the first startup configuration file, the virtual machine emulator first needs to determine whether the startup configuration file is stored in the storage module of the virtual machine emulator, and if it is determined that the startup configuration file is stored, the virtual machine emulator reads and determines the specific file content of each startup configuration file, and then determines the first startup configuration file from the stored startup configuration files based on at least the file content of each startup configuration file.
Specifically, the first startup configuration file in this embodiment further includes first virtual machine configuration information input by a user, where the first virtual machine configuration information at least includes virtual hardware configuration parameters of the first virtual machine. When the virtual machine emulator determines the first boot configuration file, the following two embodiments are specifically included:
the first embodiment is as follows:
the first starting configuration file also comprises appointed loaded target operating system information;
determining a first startup profile, comprising:
responding to a virtual machine creating instruction, and receiving second virtual machine configuration information input by a user, wherein the second virtual machine configuration information comprises virtual hardware configuration parameters of a second virtual machine;
and determining a first starting configuration file according to the second virtual machine configuration information, wherein the second virtual machine configuration information is matched with the first virtual machine configuration information.
For example, as shown in fig. 3, the virtual machine emulator receives a virtual machine creation instruction input by a user, creates a new virtual machine, defines it as a second virtual machine, and inputs second virtual machine configuration information. The second virtual machine configuration information includes virtual hardware configuration parameters of the second virtual machine and target operating system information specified to be loaded. Then, the virtual machine emulator responds to an instruction input by a user, reads specific content in the second virtual machine configuration information, performs matching search in the storage module based on a read result, and if the specific content of the first virtual machine configuration information included in a certain start configuration file is found to be completely matched with the specific content of the read second virtual machine configuration information, that is, the two configuration information have the same virtual hardware configuration parameters and the same designated target operating system, it may be determined that the second virtual machine is the same in nature as the first virtual machine at this time, and the first virtual machine is started directly based on the boot flow and the configuration file, so the virtual machine emulator determines that the start configuration file is the first start configuration file.
Example two:
a difference between this embodiment and the embodiment is that, when the second virtual machine configuration information or the first virtual machine configuration information includes the target operating system information specified to be loaded, if the virtual machine emulator determines that the first virtual machine configuration information stored in a certain boot configuration file is completely the same as the configuration parameters related to the virtual hardware in the obtained second virtual machine configuration information, and the target operating system specified to be loaded is different, the virtual machine emulator also determines that the boot configuration file is the first boot configuration file.
Example three:
determining a first startup profile, comprising:
responding to a virtual machine creating instruction, and receiving second virtual machine configuration information input by a user, wherein the second virtual machine configuration information comprises virtual hardware configuration parameters of a second virtual machine;
and determining a first starting configuration file according to the second virtual machine configuration information, wherein the virtual mainboard configuration parameters stored in the first virtual machine configuration information are matched with the virtual mainboard configuration parameters in the second virtual machine configuration information.
For example, as shown in fig. 4, the virtual machine emulator receives a virtual machine creation instruction input by the user, creates a new virtual machine, temporarily defines the new virtual machine as a second virtual machine again, and inputs second virtual machine configuration information. The second virtual machine configuration information includes at least virtual hardware configuration parameters of the second virtual machine. Then, the virtual machine emulator responds to an instruction input by a user, reads specific content in the second virtual machine configuration information, performs matching search in the storage module based on the read result, and if it is found that the specific content of the first virtual machine configuration information included in a certain startup configuration file is the same as the specific content of the read second virtual machine configuration information, the virtual motherboard configuration parameters are the same, it is indicated that the virtual motherboards of the first virtual machine and the second virtual machine are the same, and the execution result corresponding to the virtual motherboard can be executed without being executed again in the process of creating and starting the second virtual machine, and the virtual motherboard that has been created and started by the first virtual machine is directly used, that is, the execution result generated in the process of creating and starting the virtual motherboard by the first virtual machine is directly used. Accordingly, the virtual machine emulator determines that the boot configuration file is the first boot configuration file.
In addition, when the device determines whether the first startup configuration file is stored, the device may be searched based on the virtual machine configuration information specified by the user, for example, when the user wants to start a certain historical virtual machine, the virtual machine configuration information to be searched may be input in a search engine, and the search engine performs matching search based on the input information to determine the first startup configuration file.
Further, as shown in fig. 5, after determining the first boot configuration file, the method for completing the booting of the virtual machine based on the first boot configuration file and the boot process includes:
acquiring an execution result required by the virtual machine in the starting process from the first starting configuration file, wherein the required execution result is all execution results stored in the first starting configuration file or the execution results stored in the first starting configuration file and corresponding to the processing process of the virtual mainboard;
carrying out data calling on the required execution result, and determining the corresponding step in the guide flow based on the called execution result;
and skipping corresponding steps in sequence based on the required execution result, and continuing to execute other steps in the boot flow until the creation and the starting of the virtual machine are completed.
Specifically, after determining the first start configuration file, the virtual machine simulator may indicate that the first start configuration file includes a part or all of the execution results required in the current virtual machine start process. When determining the required execution result, the determination may be based on comparison of the virtual machine configuration information in the process of determining the first boot configuration file. For example, by comparing the first virtual machine configuration information and the second virtual machine configuration information, if the two pieces of configuration information are completely consistent, it can be determined that all the execution results in the first startup configuration file can be used for creating and starting the virtual machine at this time, that is, all the execution results in the first startup configuration file are required execution results. At this time, the virtual machine simulator does not need to create a virtual machine again, and directly performs steps such as initialization of the virtual hardware based on each data of the corresponding virtual hardware recorded in the first start configuration file and the boot flow until the virtual machine corresponding to the first start configuration file is started, the execution result of each boot step in the starting process does not need to be derived again, and the execution result stored in the first start configuration file is directly subjected to data calling, so that the starting speed is greatly increased. If the configuration parameters of the two pieces of configuration information only correspond to the virtual motherboard are consistent, the first boot configuration file only indicates that the execution result of the generation and initialization portion corresponding to the virtual motherboard in the boot flow is available, that is, only the execution result of the portion is the execution result required at this time. After the required execution result is determined, the virtual machine simulator carries out data calling on the required execution result, and determines a guide step corresponding to the execution result in the guide flow. And then, the virtual machine simulator executes a boot flow, directly calls a corresponding execution result after the corresponding boot step is reached, and triggers the execution of the next boot step based on the execution result, if the execution result of the next boot step can also be called without generation, directly calls the next boot step, continues to start the next boot step, executes the step according to a normal flow until no callable execution result exists, and generates a corresponding execution result until the creation and the starting of the virtual machine are completed. The above-mentioned repeatedly triggering the execution procedure of the next boot step based on the called execution result is a step jump procedure, that is, each boot step capable of directly calling the execution result is not required to be executed, each boot step can be directly skipped based on the corresponding execution result, and the boot step which needs to be normally executed to obtain the corresponding execution result is directly entered. In the process, the execution results of all the boot steps are obtained without derivation and processing, so that compared with the conventional virtual machine creating and starting process, the method of the embodiment saves more time, and enables the history data to be directly called when the history created virtual machines with the same configuration or only the virtual mainboards with the same configuration are created or started again without executing all the boot steps again.
Further, as shown in fig. 6, when a plurality of boot configuration files are stored in the virtual machine emulator,
determining a first startup profile, comprising:
responding to a virtual machine creating instruction input by a user;
determining that the second virtual machine configuration information input by the user is not received;
respectively determining the starting duration of the virtual machine corresponding to each starting configuration file;
a first startup profile is determined from a plurality of startup profiles based on a startup duration.
For example, when a plurality of start-up configuration files respectively corresponding to different virtual machines are stored in a storage module of the virtual machine simulator, when the virtual machine simulator receives a virtual machine creation instruction input by a user but does not receive second virtual machine configuration information input by the user, the virtual machine simulator may respectively determine a start-up duration for completing the corresponding virtual machine based on each start-up configuration file, and then select a first start-up configuration file from the plurality of start-up configuration files based on the duration. And then, the virtual machine simulator does not need to create a new virtual machine again, and the corresponding historical virtual machine is started directly on the basis of the first starting configuration file and the guiding process. The determining of each duration may specifically be determined according to a data size of each stored execution result, and if the data storage amount is large, the consumed time is usually long, and if the data storage amount is small, the consumed time is usually short. Or, the time consumed for starting the virtual machine corresponding to each start-up configuration file may be determined based on the time consumed for completing the start-up of each virtual motherboard and the target operating system recorded in the history. When the first start configuration file is determined, the start configuration file corresponding to the virtual machine which consumes the shortest time for completing start can be specifically selected as the first start configuration file, so that the start time of the virtual machine at this time is the shortest.
Alternatively, for the above case, the virtual machine emulator may also determine the first boot profile based on pre-stored priorities set for the respective boot profiles stored.
Further, as shown in fig. 7, the method in this embodiment further includes:
determining that the starting configuration file is not stored or determining that the stored starting configuration file does not contain a plurality of execution results at least based on the file content;
and guiding the virtual machine to complete the starting based on the guiding flow.
For example, the virtual machine simulator determines that no start-up configuration file is stored in the storage module, for example, when the virtual machine is first created, the created virtual machine is first started, or the stored start-up configuration file is found by reading the file content of the stored start-up configuration file, and determining that the stored configuration file does not contain a plurality of execution results, the virtual machine is automatically created or started according to the guiding process without calling any processing result.
For another example, when the virtual machine emulator determines that the first virtual machine configuration information is not matched with the second virtual machine configuration information completely, or only the target operating system information is matched, the virtual machine emulator may also determine that there is no first boot configuration file, and complete the creation or boot of the current virtual machine only based on the boot flow.
Further, as shown in fig. 8, the virtual machine emulator boots the virtual machine to complete the boot based on the boot flow, including:
guiding the first virtual machine to finish the starting of the virtual machine based on the boot flow, and simultaneously recording the execution results of all steps in the corresponding boot flow;
after the virtual machine is guided to finish the starting based on the guiding flow, the method further comprises the following steps:
establishing a first starting configuration file;
and storing the execution result into the first starting configuration file.
That is, if the first start-up configuration file is not found, when the virtual machine completes the creation and initialization of the virtual machine only through the boot process, the virtual machine simulator records the execution result of each step in the process of completing the creation and startup of the virtual machine based on the boot process, and after the virtual machine is started up, creates the first start-up configuration file in the storage module, and simultaneously stores all the recorded execution results, or simultaneously stores the received virtual machine configuration information input by the user, so that when the virtual machine is subsequently created again, the matched start-up configuration file can be quickly found.
As shown in fig. 9, another embodiment of the present invention also provides a virtual machine emulation apparatus, including:
a determination module to determine that a first startup profile is stored,
the processing module is used for finishing the starting of the virtual machine according to the first starting configuration file and the guide flow;
the first starting configuration file is a pre-stored file, the first starting configuration file comprises a plurality of execution results, and the plurality of execution results are generated by the processing module in order to execute the boot process so as to complete the creation and starting of the virtual machine.
For example, the virtual machine emulation device can include an open source emulation processor/open source emulation processing software, such as Qemu, Quick EMUlator. After a user starts the virtual machine simulation device and inputs a virtual machine creating instruction to the virtual machine simulation device, the determining module determines whether the virtual machine simulation device stores a first starting configuration file, wherein a plurality of execution results are stored in the first starting configuration file, and the plurality of execution results are correspondingly generated in the process that the processing module executes the guide flow in sequence to complete the creation and starting of the historical virtual machine. That is, the boot flow includes a plurality of boot steps, and when the processor executes the plurality of boot steps in sequence, an execution result is generated based on each boot step, and a next boot step needs to be executed after a previous boot step is completed and a corresponding execution result is generated.
