Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The method for creating the virtual machine can be applied to the creation of the cloud platform virtual machine in the cloud computing environment, or can also be applied to the creation of the terminal virtual machine in a common virtual machine use scene, for example, the virtual machine can be created on the cloud platform by using the method, and the virtual machine can be created on various computer terminals of a user, such as a notebook computer, a desktop computer, an all-in-one machine, and the like, by using the method.
Referring to fig. 1, a flowchart of a first embodiment of a virtual machine creation method according to the present application is shown, where the method may include the following steps:
The parameter information is some basic or necessary parameter information required for creating the virtual machine, and specifically, the parameter information may be, but is not limited to, host information, mirror information, configuration information, network information, and the like required for creating the virtual machine.
The host information may be, for example, a host name, a host number, and the like, the image information at least includes information of a target image file required for creating the virtual machine, such as a name of the target image file, and the configuration information may include information of a processor/memory/Disk resource (CPU/Mem/Disk) required for creating the virtual machine.
Parameter information such as host information, mirror image information, configuration information, network information and the like required for creating a virtual machine is generally generated by a user through executing corresponding setting operation based on actual requirements of the user, for example, in a cloud computing environment, the parameter information required for creating the virtual machine can be provided by a terminal user through parameter setting and submitted to a cloud platform, and the cloud platform creates the virtual machine according to the parameter information after acquiring the parameter information submitted by the terminal user.
102, obtaining virtual machine starting field data of a target image file required by the virtual machine based on the parameter information, wherein the starting field data comprises: and starting the virtual machine from the target image file to the field data stored in the preset time node in advance.
Different from the mode that the virtual machine is started from the image file to complete the creation of the virtual machine in the prior art, the invention provides a mode that the virtual machine is started from the memory based on the memory to create the virtual machine. Specifically, the virtual machine is started directly in the memory by restoring the virtual machine start site corresponding to the virtual machine start site data, rather than from the start node of the virtual machine start process, so as to complete the virtual machine creation on the basis of starting.
Wherein the virtual machine starts the field data and includes: and starting the virtual machine from the target image file to the field data stored in the preset time node in advance. The predetermined time node is a certain node in the virtual machine starting process, and may be, for example, a time node corresponding to when some general processes (some processes that need to be executed when starting the virtual machine based on different image files) are executed in the virtual machine starting process, and more specifically, may be, for example, a corresponding node when the virtual machine is started until the kernel is completely loaded, or an IP (Internet Protocol) address is obtained, or an initialization script is obtained, and the like.
According to the method and the device, the virtual machine is started in the image file to the preset time node in advance, and the virtual machine starting field data when the virtual machine is started to the preset time node is stored, so that the virtual machine starting field corresponding to the pre-stored field data can be directly recovered in the memory when the virtual machine is created based on the memory subsequently, and therefore the starting process from the starting node to the preset time node in the virtual machine starting process does not need to be executed in the memory, the virtual machine creating process is simplified, and the virtual machine creating efficiency is improved.
The image files can be roughly classified into windows image files, linux image files and the like, and the windows image files and the linux image files respectively comprise a plurality of different image files under the large image file categories.
In view of this, after obtaining the parameter information required for creating the virtual machine, the target image file required for creating the virtual machine may be determined according to the target image file information in the parameter information, such as the name of the target image file. And determining and acquiring the virtual machine starting site data of the target image file to realize providing support for restoring the virtual machine starting site based on the memory and establishing the virtual machine on the restored virtual machine starting site.
And 103, acquiring mirror image data in the target mirror image file corresponding to the preset time node in the starting process of the virtual machine.
The virtual machine starting field data of the target image file corresponds to a starting process from a starting node to the predetermined time node in the virtual machine starting process, so that image data corresponding to the predetermined time node in the virtual machine starting process in the target image file also needs to be obtained in order to complete a complete starting process in the virtual machine starting process.
And step 104, restoring a virtual machine starting site corresponding to the starting site data in the memory of the target host, and completing the creation of the virtual machine on the basis of the mirror image data after the preset time node on the virtual machine starting site.
The target host may be determined according to host information, such as a host name, in the parameter information, and after the target host required for creating the virtual machine is determined, host resources and network resources required for creating and allocating the virtual machine may be further allocated according to configuration information (such as CPU/Mem/Disk) and network information in the parameter information. Taking the cloud computing environment as an example, a virtual machine management platform in the cloud platform may determine a host required for creating the virtual machine according to host information, and create and allocate a host resource (such as CPU/Mem/Disk) and a network resource required for the virtual machine according to the configuration information and the network information.
In this step, on the basis of obtaining the virtual machine start-up field data of the target image file and the image data of the target image file corresponding to the predetermined time node in the virtual machine start-up process, the virtual machine start-up field corresponding to the start-up field data may be first restored in the memory of the target host, and after the virtual machine start-up field is restored, the effect is equivalent to executing the start-up process from the start node of the virtual machine start-up to the predetermined time node in the memory, so that, later, on the restored virtual machine start-up field, the subsequent process in the virtual machine start-up process, that is, the process after the predetermined time node, is completed by using the image data after the predetermined time node, thereby implementing the creation of the virtual machine.
According to the virtual machine creation method provided by the embodiment of the application, the virtual machine starting site corresponding to the virtual machine starting site data is recovered in the memory of the target host, and the subsequent starting process of the virtual machine is continuously completed on the recovered virtual machine starting site, so that the virtual machine is created; the virtual machine starting field data is stored in a preset time node after the virtual machine is started from a target image file required by the virtual machine. Therefore, the virtual machine creating scheme based on the memory is provided, when the virtual machine is created, the image file does not need to be read, the I/O load of the system is reduced, the virtual machine can be created directly in a memory (such as a target host memory) based on recovery of a virtual machine starting site, and at least some basic processes required for creating the virtual machine, such as guiding, loading, kernel starting, initialization and the like, can be omitted, so that the virtual machine starting speed is higher, and the virtual machine creating efficiency is improved.
Example two
In this embodiment two, a possible implementation manner of obtaining the virtual machine startup field data of the target image file required for creating the virtual machine in the step 102 is provided, and referring to a flowchart of fig. 2, the step 102 may be implemented by the following steps:
In the method of this embodiment, the virtual machine is started from the image file to the predetermined time node in advance, and the complete start site data corresponding to the virtual machine start site from the image file to the predetermined time node is stored.
For example, in the cloud computing environment, for various image files maintained in an image server of a cloud platform, such as various windows-type image files and various linux-type image files, a virtual machine is started from each image file to a predetermined time node in advance, and when the virtual machine is started from each image file to the predetermined time node, complete start-up field data of a start-up field of the virtual machine corresponding to each image file is stored, so that support can be provided for the following virtual machine creation requirements of different terminals on the cloud platform based on different images.
On the basis of the preprocessing, when a virtual machine creating requirement based on the target image file exists, complete starting field data of a virtual machine starting field corresponding to the target image file, which is stored in advance, can be directly obtained. Still taking a cloud computing environment as an example, a target host can firstly search whether complete start-up field data corresponding to a target image file exists in a local machine, if not, the complete start-up field data of the target image file is read from an image server to the local machine and cached (so that when the local machine needs to perform additional virtual machine creation based on the target image file subsequently, start-up field data support of the local machine is provided, and therefore data acquisition efficiency is improved, and I/O load of a system is reduced).
According to the method, the starting field data corresponding to the target image file is obtained in a complete starting field data mode, and the process of obtaining the starting field data of the target image file can be visual and simple by using the mode, so that the method has high obtaining efficiency.
EXAMPLE III
In a third embodiment, the image information in the parameter information further includes a target type to which the target image file belongs, and on this basis, this embodiment provides another possible implementation manner for obtaining the virtual machine startup field data of the target image file required for creating the virtual machine in step 102.
Referring to the flowchart of the second embodiment of the virtual machine creation method in the present application shown in fig. 3, the step 102 may be implemented by the following steps:
301, obtaining common start site data corresponding to the image file of the target type; wherein the common data of the starting site comprises: and when the various image files corresponding to the target types are started to the preset time node, the various image files respectively correspond to the shared data in the virtual machine starting field data.
The present embodiment is different from the second embodiment in the manner of acquiring the data of the start site.
In this embodiment, the predetermined time node corresponding to the virtual machine start-up field data is preferably set as a node corresponding to some general processes executed in the virtual machine start-up process, for example, a time node corresponding to a process of executing kernel loading or acquiring an IP or acquiring an initialization script.
For a conventional virtual machine image of the same series/type, such as a conventional virtual machine image of a certain series/type in a windows or linux category, because the virtual machine startup field data corresponding to each image file in the virtual machine images is data stored after a certain general process is executed in the virtual machine startup process, and does not contain any service information, most of the data in each virtual machine startup field data corresponding to the virtual machine images are generally the same, and only a small part of the data is different.
In view of this, the present embodiment proposes to further process each virtual machine startup field data corresponding to a same series/type of virtual machine image, including extracting common data and specific data in each virtual machine startup field data, and compressing the extracted data, so that, when storing the virtual machine startup field data of the same series/type of image file, it is different from the second implementation of storing the complete startup field data of each image file separately.
Therefore, based on the storage method for data in the startup site of the virtual machine in the embodiment, when there is a virtual machine creation requirement based on the target image file, the target type to which the target image file belongs may be read from the image information included in the parameter information required for creating the virtual machine, and the startup site common data corresponding to the image file of the target type may be obtained.
In the cloud computing environment, the target host computer can also search the common start-up site data corresponding to the target type image file in the local computer at first, if the local computer does not have the required common start-up site data, the common start-up site data corresponding to the target type image file is continuously read from the image server of the cloud platform and cached in the local computer, so that the common start-up site data support of the local computer is provided for the virtual machine when the virtual machine is required to be created based on the same series/type image files in the local computer subsequently.
After the common data of the starting site corresponding to the target image file is obtained, the special data of the starting site corresponding to the target image file also needs to be obtained. The acquisition of the startup site specific data in the cloud computing environment is similar to the acquisition of the startup site common data (based on native or mirror server acquisition), and is not described in detail herein.
And 303, combining the common data of the starting site and the special data of the starting site to obtain the starting site data of the virtual machine of the target image file.
After the common start site data and the specific start site data corresponding to the target image file are obtained, the common start site data and the specific start site data can be merged to obtain complete start site data corresponding to the target image file. Subsequently, the scheme of the invention can be used for realizing the creation of the virtual machine based on the memory startup field recovery.
According to the method, the starting site data corresponding to the target image file is obtained in a mode of combining the common starting site data and the specific starting site data, and by means of the mode, storage resources of the starting site data of the virtual machine can be effectively saved.
Example four
The embodiment of the present invention provides a possible implementation manner of the step 104, and referring to a flowchart of a fourth embodiment of a virtual machine creation method according to the present application shown in fig. 4, in the step 104, that is, a virtual machine start site corresponding to the start site data is recovered in a memory of a target host corresponding to the host information, and creation of a virtual machine is completed on the virtual machine start site based on the mirror image data after the predetermined time node, which may be implemented by the following processing procedures:
The virtual machine starting site corresponding to the target image file can be recovered in the memory of the target host by copying the virtual machine starting site data corresponding to the target image file to the memory of the target host.
For example, the directly obtained complete start-up field data may be copied in the memory of the target host, or the start-up field data obtained by merging the common start-up field data and the specific start-up field data may be copied to recover the start-up field of the virtual machine corresponding to the target image file.
And 402, configuring parameters required by the current virtual machine creation in the virtual machine starting site.
The generation and storage of the virtual machine startup field data of the target image file are specifically based on a specific virtual machine creation process, so that the virtual machine startup field data necessarily includes some basic information specific to the specific virtual machine creation process, such as a virtual machine name, a UUID (universal Unique Identifier), Mac, IP, disk mapping, and the like.
In view of this, after the virtual machine start site corresponding to the virtual machine start site data of the target image file is restored in the memory, the basic information needs to be reconfigured in the restored site according to the virtual machine creation requirement of this time, such as reconfiguring the virtual machine name, UUID, Mac, IP, disk mapping, and the like.
And step 403, completing the virtual machine starting process corresponding to the other stage by using the mirror image data after the predetermined time node, so as to create the virtual machine.
Then, in the virtual machine starting site obtained after the basic information configuration is carried out again, the image data after the preset time node in the target image file is utilized to continue to complete the unfinished flow part (namely, the flow part after the preset time node) in the virtual machine starting process until the virtual machine starting flow is finished, and the virtual machine is correspondingly established.
That is to say, when the scheme of the application is used for creating a virtual machine based on a memory, the virtual machine creation method comprises two stages of work, wherein the first stage is to directly recover a virtual machine starting site in a host memory based on obtained virtual machine starting site data, wherein the virtual machine starting site is a site corresponding to a target image file starting virtual machine to a predetermined time node in advance, so that a starting process from a starting node to the predetermined time node in a virtual machine starting process does not need to be executed in the memory; the second stage is to continue to complete the subsequent flow in the virtual machine starting process in the recovered virtual machine starting site. The starting process from the starting node to the preset time node in the virtual machine starting process is omitted in the memory, so that the virtual machine creating efficiency can be improved.

Taking the cloud computing environment as an example, a virtual machine management platform in the cloud platform may determine a host required for creating the virtual machine according to host information, and create and allocate a host resource (such as CPU/Mem/Disk) and a network resource required for the virtual machine according to the configuration information and the network information.
In this step, on the basis of obtaining the virtual machine start-up field data of the target image file and the image data of the target image file corresponding to the predetermined time node in the virtual machine start-up process, the virtual machine start-up field corresponding to the start-up field data may be first restored in the memory of the target host, and after the virtual machine start-up field is restored, the effect is equivalent to executing the start-up process from the start node of the virtual machine start-up to the predetermined time node in the memory, so that, later, on the restored virtual machine start-up field, the subsequent process in the virtual machine start-up process, that is, the process after the predetermined time node, is completed by using the image data after the predetermined time node, thereby implementing the creation of the virtual machine.
According to the electronic device provided by the embodiment of the application, the virtual machine starting site corresponding to the virtual machine starting site data is recovered in the memory of the target host, and the subsequent starting process of the virtual machine is continuously completed on the recovered virtual machine starting site, so that the virtual machine is created; the virtual machine starting field data is stored in a preset time node after the virtual machine is started from a target image file required by the virtual machine. Therefore, the virtual machine creating scheme based on the memory is provided, when the virtual machine is created, the image file does not need to be read, the I/O load of the system is reduced, the virtual machine can be created directly in a memory (such as a target host memory) based on recovery of a virtual machine starting site, and at least some basic processes required for creating the virtual machine, such as guiding, loading, kernel starting, initialization and the like, can be omitted, so that the virtual machine starting speed is higher, and the virtual machine creating efficiency is improved.
EXAMPLE six
In this embodiment, the second obtaining unit may specifically obtain, by the following processing procedures, virtual machine startup field data of a target image file required for creating a virtual machine:
and acquiring complete start site data corresponding to the virtual machine start site of the target image file which is directly stored in advance.
In the method of this embodiment, the virtual machine is started from the image file to the predetermined time node in advance, and the complete start site data corresponding to the virtual machine start site from the image file to the predetermined time node is stored.
For example, in the cloud computing environment, for various image files maintained in an image server of a cloud platform, such as various windows-type image files and various linux-type image files, a virtual machine is started from each image file to a predetermined time node in advance, and when the virtual machine is started from each image file to the predetermined time node, complete start-up field data of a start-up field of the virtual machine corresponding to each image file is stored, so that support can be provided for the following virtual machine creation requirements of different terminals on the cloud platform based on different images.
On the basis of the preprocessing, when a virtual machine creating requirement based on the target image file exists, complete starting field data of a virtual machine starting field corresponding to the target image file, which is stored in advance, can be directly obtained. Still taking a cloud computing environment as an example, a target host can firstly search whether complete start-up field data corresponding to a target image file exists in a local machine, if not, the complete start-up field data of the target image file is read from an image server to the local machine and cached (so that when the local machine needs to perform additional virtual machine creation based on the target image file subsequently, start-up field data support of the local machine is provided, and therefore data acquisition efficiency is improved, and I/O load of a system is reduced).
According to the method, the starting field data corresponding to the target image file is obtained in a complete starting field data mode, and the process of obtaining the starting field data of the target image file can be visual and simple by using the mode, so that the method has high obtaining efficiency.
EXAMPLE seven
In a seventh embodiment, the image information in the parameter information further includes a target type to which a target image file belongs, and on this basis, this embodiment provides another possible implementation manner of the second obtaining unit, and in this embodiment, the second obtaining unit may specifically obtain, by the following processing procedures, virtual machine startup field data of the target image file required for creating a virtual machine:
obtaining common start site data corresponding to the target type of image file; wherein the common data of the starting site comprises: when various image files corresponding to the target type are started to the preset time node, the corresponding virtual machine starts the shared data in the field data; acquiring special data of a starting site of the target image file; the specific data of the starting site of the target image file comprises: when the target image file is started to the preset time node, the corresponding virtual machine starts other data in the field data except the common data of the start field; and combining the common data of the starting site and the special data of the starting site to obtain the starting site data of the virtual machine of the target image file.
The present embodiment is different from the start-up field data acquisition method provided in the sixth embodiment.
In this embodiment, the predetermined time node corresponding to the virtual machine start-up field data is preferably set as a node corresponding to some general processes executed in the virtual machine start-up process, for example, a time node corresponding to a process of executing kernel loading or acquiring an IP or acquiring an initialization script.
For a conventional virtual machine image of the same series/type, such as a conventional virtual machine image of a certain series/type in a windows or linux category, because the virtual machine startup field data corresponding to each image file in the virtual machine images is data stored after a certain general process is executed in the virtual machine startup process, and does not contain any service information, most of the data in each virtual machine startup field data corresponding to the virtual machine images are generally the same, and only a small part of the data is different.
In view of this, the present embodiment proposes to further process each virtual machine startup field data corresponding to a same series/type of virtual machine image, including extracting common data and specific data in each virtual machine startup field data, and compressing the extracted data, so that, when storing the virtual machine startup field data of the same series/type of image file, it is different from the second implementation of storing the complete startup field data of each image file separately.
Therefore, based on the storage method for data in the startup site of the virtual machine in the embodiment, when there is a virtual machine creation requirement based on the target image file, the target type to which the target image file belongs may be read from the image information included in the parameter information required for creating the virtual machine, and the startup site common data corresponding to the image file of the target type may be obtained.
In the cloud computing environment, the target host computer can also search the common start-up site data corresponding to the target type image file in the local computer at first, if the local computer does not have the required common start-up site data, the common start-up site data corresponding to the target type image file is continuously read from the image server of the cloud platform and cached in the local computer, so that the common start-up site data support of the local computer is provided for the virtual machine when the virtual machine is required to be created based on the same series/type image files in the local computer subsequently.
After the common data of the starting site corresponding to the target image file is obtained, the special data of the starting site corresponding to the target image file also needs to be obtained. The acquisition of the startup site specific data in the cloud computing environment is similar to the acquisition of the startup site common data (based on native or mirror server acquisition), and is not described in detail herein.
After the common start site data and the specific start site data corresponding to the target image file are obtained, the common start site data and the specific start site data can be merged to obtain complete start site data corresponding to the target image file. Subsequently, the scheme of the invention can be used for realizing the creation of the virtual machine based on the memory startup field recovery.
According to the method, the starting site data corresponding to the target image file is obtained in a mode of combining the common starting site data and the specific starting site data, and by means of the mode, storage resources of the starting site data of the virtual machine can be effectively saved.
Example eight
The embodiment of the present invention provides a possible implementation manner of the virtual machine creating unit, where the virtual machine creating unit may complete the creation of a virtual machine through the following processing procedures:
the virtual machine starting site of the target image file is recovered in the memory of the target host by copying the virtual machine starting site data of the target image file to the memory of the target host; performing parameter configuration required by the current virtual machine creation in the virtual machine starting site; and finishing the starting process of the virtual machine corresponding to the other stages by using the mirror image data after the preset time node so as to establish the virtual machine.
The virtual machine starting site corresponding to the target image file can be recovered in the memory of the target host by copying the virtual machine starting site data corresponding to the target image file to the memory of the target host.
For example, the directly obtained complete start-up field data may be copied in the memory of the target host, or the start-up field data obtained by merging the common start-up field data and the specific start-up field data may be copied to recover the start-up field of the virtual machine corresponding to the target image file.
The generation and storage of the virtual machine startup field data of the target image file are specifically based on a specific virtual machine creation process, so that the virtual machine startup field data necessarily includes some basic information specific to the specific virtual machine creation process, such as a virtual machine name, a UUID (universal Unique Identifier), Mac, IP, disk mapping, and the like.
In view of this, after the virtual machine start site corresponding to the virtual machine start site data of the target image file is restored in the memory, the basic information needs to be reconfigured in the restored site according to the virtual machine creation requirement of this time, such as reconfiguring the virtual machine name, UUID, Mac, IP, disk mapping, and the like.
Then, in the virtual machine starting site obtained after the basic information configuration is carried out again, the image data after the preset time node in the target image file is utilized to continue to complete the unfinished flow part (namely, the flow part after the preset time node) in the virtual machine starting process until the virtual machine starting flow is finished, and the virtual machine is correspondingly established.
That is to say, when the scheme of the application is used for creating a virtual machine based on a memory, the virtual machine creation method comprises two stages of work, wherein the first stage is to directly recover a virtual machine starting site in a host memory based on obtained virtual machine starting site data, wherein the virtual machine starting site is a site corresponding to a target image file starting virtual machine to a predetermined time node in advance, so that a starting process from a starting node to the predetermined time node in a virtual machine starting process does not need to be executed in the memory; the second stage is to continue to complete the subsequent flow in the virtual machine starting process in the recovered virtual machine starting site. The starting process from the starting node to the preset time node in the virtual machine starting process is omitted in the memory, so that the virtual machine creating efficiency can be improved.
