Background
When a virtual machine such as a cloud computer and a cloud desktop is just started, a service such as a cloud-host initialization program (cloud-init) in the virtual machine needs to acquire metadata of the virtual machine and perform initialization configuration operations such as a name, a password and a network. At present, the following two methods are commonly adopted to obtain metadata of a virtual machine:
one is in the form of a Compact Disc Read-Only Memory (cd rom), in which a file containing metadata information is mounted to a virtual machine, and the inside of the virtual machine reads the cd rom information to obtain corresponding metadata of the virtual machine. However, the metadata acquisition method not only occupies the cd rom drive of the virtual machine, so that the virtual machine cannot plug in other cd roms, but also increases the security risk of metadata file loss because the cd rom operation authority is opened to the use object.
The other method is to establish a network channel for the virtual machine to access an external metadata server, and acquire corresponding metadata from the metadata server through the established network channel. However, when metadata is obtained in batch, the virtual machine needs to access the metadata server for multiple times, which occupies a relatively high network bandwidth, which affects the normal network communication function of the virtual machine, and is easy to cause network exception, thereby increasing the failure rate of metadata acquisition.

All other embodiments obtained by a person skilled in the art based on the embodiments described in the present application without any creative effort belong to the protection scope of the technical solution of the present application.
Some terms in the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.
1. Cloud host initialization program (cloud-init):
the cloud-init is an open-source cloud initialization program, is widely applied to various large cloud platforms, and is used for initializing and configuring custom information (such as information of host names, passwords, user data and the like) specified in newly created elastic cloud servers.
2. Compact Disc Read-Only Memory (cdrom):
the cd rom belongs to the external memory device and is an optical disk used on a computer. The optical disc can be written with data only once, and the information is permanently stored on the optical disc and read by the optical disc drive when in use.
3. Virtual Machine (Virtual Machine):
the virtual machine is an emulator of a computer system, and can provide the functions of a physical computer by simulating the complete computer system having the functions of a complete hardware system and operating in a completely isolated environment through software.
According to the application scenario of the virtual machine and the correlation with the direct machine, the virtual machine can be divided into a system virtual machine and a program virtual machine. The system virtual machine provides a complete system platform that can run a complete operating system, while the program virtual machine is designed to run a single computer program. However, whatever virtual machine is used, the essence of the virtual machine is software running on the virtual machine, and the virtual machine is limited in the resources provided by the virtual machine.
The following briefly introduces the design concept of the embodiments of the present application:
when a virtual machine such as a cloud computer and a cloud desktop is just started, a cloud-init service in the virtual machine needs to acquire virtual machine metadata and perform initialization configuration operations such as name, password and network. At present, the following two methods are commonly used to obtain metadata of a virtual machine:
one is in a cdrom form, a file containing metadata information is mounted to a virtual machine, and the inside of the virtual machine obtains corresponding virtual machine metadata by reading the cdrom information. However, the metadata acquisition method not only occupies the cd rom drive of the virtual machine, so that the virtual machine cannot plug in other cd roms, but also increases the security risk of metadata file loss because the cd rom operation authority is opened to the use object.
The other method is to establish a network channel for the virtual machine to access an external metadata server, and acquire corresponding metadata from the metadata server through the established network channel. However, when metadata is obtained in batch, the virtual machine needs to access the metadata server for many times, which occupies a higher network bandwidth, which affects the normal network communication function of the virtual machine, and is easy to cause network abnormality, thereby increasing the failure rate of metadata obtaining.
In view of this, an embodiment of the present application provides a metadata obtaining method. The method comprises the following steps: acquiring system management peripheral information of a self operating system based on a system query command input by a use object; and then obtaining corresponding virtual machine metadata from the system management peripheral information, wherein the metadata is used for the initialization configuration operation of the virtual machine.
Compared with the traditional metadata acquisition method, the method provided by the embodiment of the application does not need to plug in the cdrom, so that the cd drive is not occupied, the situations of mistakenly deleting files, revealing files and the like due to the fact that the cdrom operation authority is opened to the use object are avoided, and the safety risk of metadata file loss is effectively reduced.
In addition, the method provided by the embodiment of the application is executed inside the virtual machine, and does not need to communicate with other terminal devices through a network to acquire corresponding metadata, so that when the metadata of the virtual machine is acquired in batches, a small network bandwidth is consumed under the condition that the normal network communication function of the virtual machine is not influenced, and a large amount of metadata can be acquired quickly and accurately.
The preferred embodiments of the present application will be described in conjunction with the drawings of the specification, it should be understood that the preferred embodiments described herein are only for illustrating and explaining the present application, and are not intended to limit the present application, and the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1A illustrates an application scenario of an embodiment of the present application, where the scenario includes multiple physical terminal devices 110. Wired communication or wireless communication is established between each physical terminal device 110, and each physical terminal device 110 may be located in the same local area network or in different local area networks, which is not limited herein.
The physical end device 110 runs the deployed virtual machine software in response to a start operation triggered using the object. When the virtual machine is started, the virtual machine acquires system management peripheral information of an operating system of the virtual machine based on a system query command input by a using object; and then obtaining corresponding metadata from the system management peripheral information, wherein the metadata is used for the initialization configuration operation of the virtual machine.
Fig. 1B shows another application scenario of the embodiment of the present application, which includes two physical terminal devices 110 'and one server 130'. The physical terminal equipment 110 'and the server 130' establish wired communication or wireless communication therebetween, which is not limited herein.
The physical terminal apparatus 110 'presents an access interface 120' thereto in response to an access operation triggered using an object; the virtual machine on the server 130 'is remotely accessed based on information such as the web address input in the access interface 120' using the object. When the virtual machine is started, the virtual machine acquires system management peripheral information of an operating system of the virtual machine based on a system query command input by a using object; and then obtaining corresponding metadata from the system management peripheral information, wherein the metadata is used for the initialization configuration operation of the virtual machine.
The physical terminal device 110 and the physical terminal device 110' of the embodiment of the present application are both computer devices used by a user. The computer device can be a personal computer, a mobile phone, a tablet computer, a notebook, an e-book reader, an intelligent home and other computer devices with certain computing capability.
The server 130' in this embodiment of the application may be an independent physical server, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be a cloud server that provides basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a Network service, cloud communication, a middleware service, a domain name service, a security service, a Content Delivery Network (CDN), and a big data and artificial intelligence platform, which is not limited herein.
Referring to the flowchart shown in fig. 2A, when the virtual machine is started, the process of acquiring the metadata of the virtual machine is as follows:
s201: and the virtual machine acquires the system management peripheral information of the operating system of the virtual machine based on the system query command input by the using object.
Before executing step 201, the virtual machine presents a command input interface to the usage object in response to a command input operation triggered by the usage object, so that the usage object inputs a system query command in the command input interface.
For example, a user inputs a su command in a terminal interface of the virtual machine and returns, and when the terminal interface has a word "password", the user inputs an account password of the virtual machine, and the command input interface shown in fig. 2B is presented to the user.
Then, after presenting a command input interface to the user object, before executing step 201, the virtual machine obtains a system query command input by the user object, then judges whether the system query command is a legal command, and if so, continues to obtain system management peripheral information of the operating system of the virtual machine based on the system query command input by the user object; otherwise, sending alarm information to the object to prompt the other party to re-input a new system query command.
Specifically, the virtual machine may determine whether the system query command input using the object is a legal command by performing the following operations:
the virtual machine acquires a corresponding grammar rule based on the system type of the operating system; judging whether the system query command meets the grammar rule, if so, determining the system query command to be a legal command; otherwise, determining that the system query command is an illegal command.
In the embodiment of the application, corresponding grammar rules are configured for different types of operating systems. Using a dmidcode command in a virtual machine running a Linux operating system to check system management peripheral information; and using a wmic command in the virtual machine running the Windows operating system to view the system management peripheral information.
Assuming that a Linux operating system is run on a virtual machine, a system query command input by a user is 'wmic-em-string 1', and the command does not conform to a syntax rule of the operating system, therefore, the virtual machine presents warning information 'not an internal or external command or an executable program, please re-input the system command' as shown in fig. 2C to the user in a command input interface, and prompts the other party to re-input a new system query command.
Supposing that a Linux operating system is operated on a virtual machine, a system query command input by a user is dmidcode-item-string 1, the virtual machine determines that the system query command is a legal command because the command accords with a grammar rule of the operating system, and then system management peripheral information of the operating system of the virtual machine is acquired based on the system query command.
In the method for acquiring metadata of a virtual machine provided in the embodiment of the present application, a System administrator adds a custom System Management peripheral (i.e., system Management Basic Input Output System, smbios) field in a virtual machine start parameter in advance. This field contains metadata necessary for the virtual machine startup, and therefore, at the time of virtual machine startup, the system management peripheral information of the own operating system can be acquired from the virtual machine startup parameters by using the system query command input by the object.
For example, taking a kvm virtual machine with a centros 7 as an example, a system management peripheral field "-smbios type =11, value = name = centros 7-test1" is added to a virtual machine start parameter, and the value of this field is metadata "name = centros 7-test1" required when the virtual machine starts.
S202: the virtual machine obtains corresponding metadata from the system management peripheral information, and the metadata is used for the initialization configuration operation of the virtual machine.
Taking the previous example as an example of starting a kvm virtual machine of the centros 7, a system query command input by a user is "dmidcode-item-string 1", and the virtual machine obtains corresponding metadata "name = centros 7-test1" from system management peripheral information based on data information to be queried. Compared with the traditional metadata acquisition method, the method provided by the embodiment of the application does not need to plug in the cdrom, so that the cd drive is not occupied, the situations of mistakenly deleting files, revealing files and the like due to the fact that the cdrom operation authority is opened to the use object are avoided, and the safety risk of metadata file loss is effectively reduced.
In addition, the method provided by the embodiment of the application is executed inside the virtual machine, and does not need to communicate with other terminal devices through a network to acquire corresponding metadata, so that when the metadata of the virtual machine is acquired in batches, a small network bandwidth is consumed under the condition that the normal network communication function of the virtual machine is not influenced, and a large amount of metadata can be acquired quickly and accurately.
Referring to the flowchart shown in fig. 3A and the logic diagram shown in fig. 3B, the process of acquiring metadata in the kvm virtual machine of centros 7 is as follows:
s301: when the virtual machine is started, a user sends a su command to the virtual machine and executes the carriage return operation;
s302: when the virtual machine receives a su command, responding to the carriage return operation triggered by a user, and presenting prompt information of 'inputting a password' in a terminal interface;
s303: a user sends a corresponding account password to a virtual machine;
s304: when the virtual machine receives the account password, a command input interface is presented to a user;
s305: the user sends a system query command "dmidcode-item-string 1" to the virtual machine;
s306: when the virtual machine determines that the system query command is a legal command, the virtual machine acquires system management peripheral information of the operating system of the virtual machine based on the system query command;
s307: the virtual machine obtains corresponding metadata 'name = centros 7-test 1' from the system management peripheral information;
s308: the virtual machine presents the corresponding metadata "name = centros 7-test1" to the user.
The embodiment of the application also provides a metadata acquisition device based on the same inventive concept as the embodiment of the method. As shown in fig. 4, the metadata obtaining apparatus 400 may include:
an obtaining unit 401, configured to obtain system management peripheral information of a self operating system based on a system query command input by a user object;

in response to a command input operation triggered by the use object, a command input interface is presented to the use object so that the use object inputs a system query command in the command input interface.

acquiring a system query command input by using an object;
judging whether the system query command is a legal command, if so, continuing to acquire system management peripheral information of the operating system based on the system query command input by the using object; otherwise, sending alarm information to the object to prompt the other party to re-input a new system query command.
Optionally, the command auditing unit 404 determines whether the system query command is a legal command by performing the following operations:
acquiring a corresponding grammar rule based on the system type of the operating system;
judging whether the system query command meets a grammar rule, if so, determining the system query command as a legal command; otherwise, determining that the system query command is an illegal command.
