Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.

The configuration method of the network protocol address provided by the embodiment of the application can be widely applied to various cloud platforms, servers or terminal equipment capable of configuring the network protocol address for the online virtual machine. The online virtual machine refers to a virtual machine which has already been created with an IPv4 network or an IPv6 network and can normally run a service, that is, a virtual machine which has already been created and is running. The terminal devices include, but are not limited to, smart phones, tablet computers, notebook computers, desktop computers, and the like, and are not limited thereto. The cloud platform includes, but is not limited to, an OpenStack cloud platform, etc., and for convenience of description, the cloud platform will be described below as an example. Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system provided in an embodiment of the present application. As shown in fig. 1, the communication system provided in the embodiment of the present application includes a cloud platform and virtual machines, where the virtual machines include a virtual machine a, a virtual machine B, …, and a virtual machine C. The cloud platform receives a network protocol address configuration request sent by any virtual machine, and can send a network protocol address corresponding to a physical address to the virtual machine according to the physical address included in the network protocol address configuration request.

For convenience of understanding, prior to describing the method provided by the embodiment of the present application, the related knowledge related to the method provided by the embodiment of the present application is briefly described as follows:

1. information Technology (IT) environments of enterprises and service providers are continuously evolving, and cloud computing is taken as a necessary trend of future development of the enterprise IT, so that brand-new service selection is provided for enterprise customers, and meanwhile, the requirement on service delivery is also provided. Cloud computing is an internet-related service-based add-on, use, and delivery model that provides dynamically scalable and virtualized resources over the internet. In brief, the cloud computing uses the transmission capability of the internet to transfer the storage and processing process of data from the local server to the internet, is not a new technology, but is a product of development and fusion of traditional IT technologies such as distributed computing, parallel computing, network storage, virtualization and the like, and is a service mode. Cloud computing is classified into narrow-sense cloud computing and generalized cloud computing. Cloud computing in the narrow sense refers to a mode of delivery and use of IT infrastructure, meaning that required resources (hardware, platforms, software) are obtained in an on-demand, easily scalable manner over a network. The network that provides the resources is referred to as the "cloud". The broad cloud computing refers to a delivery and use mode of a service, and refers to obtaining a required service in an on-demand and easily-extensible manner through a network, wherein the service can be IT (information technology) infrastructure and software, and can also be any other service.

Virtualization technology has been an important driving factor for the development of cloud computing. As an infrastructure of cloud computing, virtualization of desktops, storage and servers has been developed well, and network virtualization enables network switching equipment which is the infrastructure to support a network virtualization multi-tenant architecture, effectively separates a physical network from a logic network, meets the service characteristics of cloud computing, and improves the utilization rate of network resources. In brief, by using a host virtualization technology, a plurality of virtual machines can be run on one physical host, and the virtual machines are independent and do not affect each other, so that a user can flexibly install any software on the virtual machines. The host virtualization technology isolates application programs running on the same host, avoids resource conflict, and can dynamically migrate hardware resources which are not fully utilized to the most needed application programs, thereby improving the utilization rate of bottom hardware resources. With the increasing number of virtual machines, the number of IP addresses required for cloud computing is also increasing proportionally.

2. The transmission Control Protocol/network Protocol (TCP/IP) is the most successful network system and Protocol specification in the world at present, and is also the most basic communication Protocol in the network. The IP protocol is a protocol of a network layer in the TCP/IP protocol suite, which is a core protocol of the TCP/IP protocol suite, and the version number of the current IP protocol is 4, i.e., IPv 4. IPv4 is The fourth revision of The Internet Engineering Task Force (IETF) in The development of Internet protocols, which is also The first widely deployed version of The protocol. IPv4 has been used for thirty-three years as it evolved, and IPv4, which uses a 32-bit (4-byte) address length, can theoretically allocate addresses to 40 billion hosts throughout the Internet. However, with the explosion of the internet, the limited address space defined by IPv4 will be exhausted soon, and the shortage of the address space will certainly hinder the further development of the internet. Therefore, IPv6 was designed and proposed as a next-generation IP protocol instead of IPv4 to redefine the address space and solve the address shortage problem. The IPv6 adopts the address length of 128 bits (16 bytes), and estimates the addresses which can be actually distributed by the IPv6 according to a conservative method, and more than 1000 IP addresses can be distributed in each square meter of the whole earth. In addition to solving the problem of IP address shortage once and for all, other problems that are difficult to solve in IPv4, such as end-to-end IP connectivity, quality of service (QoS), security, multicast, mobility, plug and play, etc., are also considered in the design process of IPv 6.

In the embodiment of the present application, the first network protocol may include, without limitation, an IPv4 protocol or an IPv6 protocol, and the second network protocol may also include, without limitation, an IPv4 protocol or an IPv6 protocol, and the first network protocol and the second network protocol are different. For example, when the first network protocol is the IPv4 protocol, the second network protocol is the IPv6 protocol; when the first network protocol is the IPv6 protocol, the second network protocol is the IPv4 protocol. For convenience of description, all the embodiments described in the following application are described by taking the first network protocol as the IPv4 protocol and the second network protocol as the IPv6 protocol as examples.

3. The OpenStack is an open source cloud computing platform developed by OpenStack community developers and cloud computing technical experts, and aims to provide a simple, large-scale expandable and function-rich solution for cloud infrastructure of public clouds and private clouds. OpenStack has been developed to date, integrating a total of several components: nova (computing service), Neutron (web service), Swift (object storage service), circle (block storage service), company (mirror service), Keystone (authentication service), Horizon (UI service), Ceilometer (monitoring service), Heat (cluster service), and Trove (database service).

4. Neutron as a core component of OpenStack can provide Network support for the whole OpenStack environment, including two-layer switching, three-layer routing, load balancing, firewall and Virtual Private Network (VPN), etc. Neutron provides a flexible framework by which both open source and commercial software can be deployed to implement these functions. Network resources managed by Neutron include a main network (network), a subnet (subnet), and a port (port). Wherein, the network can be regarded as an isolated two-layer broadcast domain, and the subnet can be regarded as an IP address pool (IPv4 address pool or IPv6 address pool). The networks and the subnets are in a one-to-many relationship, that is, there may be multiple different subnets under one network, but one subnet can only belong to one network, and an IPv4subnet (i.e., IPv4subnet) and an IPv6subnet (i.e., IPv6subnet) constructed in this embodiment all belong to the same network, that is, the IPv4subnet and the IPv6subnet share an isolated two-layer broadcast domain. A port can be seen as a port on a virtual switch, on which a physical address and a network protocol address, i.e. a Media Access Control (MAC) address and an IP address (IPv4 address and/or IPv6 address) are defined, where the IP address of the port (IPv4 address or IPv6 address) is allocated from a subnet (i.e. an IPv4 address pool or IPv6 address pool). When a Virtual network Interface (VIF) of a Virtual machine is connected to a port, that is, when the VIF of the Virtual machine is bound to the port, the port assigns a physical address and an IP address (IPv4 address and/or IPv6 address) to the VIF, where the port and the VIF are in a one-to-one relationship.

5. The component of Neutron that provides Dynamic Host Configuration Protocol (DHCP) services is the DHCP agent. When the DHCP agent runs on the network node, the DHCP function is realized through dnsmasq by default. dnsmasq is an open source software providing DHCP and DNS services, and when it is used as a DNS nameresolution server, it can improve the connection speed to the visited web address by caching DNS requests, and when it is used as a DHCP server, it can be used to assign IP addresses and provide routing, etc. In the embodiment of the application, only the function of providing the DHCP service by the dnsmasq is concerned, that is, when a network is created and DHCP is enabled on a subnet, a DHCP agent on a network node starts a dnsmasq process to provide the DHCP service for the network. The dnsemasq process and the network are in a one-to-one relationship, that is, one dnsemasq process can provide DHCP service for all sub-nets in the same network.

According to the configuration method of the network protocol address provided by the embodiment of the application, by determining the virtual machine identifier of the virtual machine, the first network protocol configuration information (i.e., IPv4 configuration information) of the virtual machine can be queried from the database based on the virtual machine identifier, where the first network protocol configuration information includes a physical address of the virtual machine, a first network protocol address (i.e., IPv4 address) of the virtual machine, and a network identifier of a host network to which the virtual machine belongs. Determining a configuration file corresponding to the network identifier, adding the physical address and the target network protocol address to the configuration file by acquiring the target network protocol address (namely the IPv6 address), and configuring the target network protocol address for the virtual machine according to the configuration file containing the target network protocol address. By adopting the embodiment of the application, the online virtual machine can be smoothly upgraded from IPv4 to IPv4/IPv6 dual-protocol stack, the upgrading cost is reduced, and the applicability is strong.

In the embodiment of the application, the virtual machine is an online virtual machine which has already created an IPv4 network and can normally run a service. For ease of understanding, referring to fig. 2, fig. 2 is a schematic diagram of a system architecture of an IPv4 network provided in an embodiment of the present application. As shown in fig. 2, the IPv4 network in the embodiment of the present application is created on a cloud platform, where the IPv4 network includes a created main network 1, and an IPv4subnet 1, ports, and virtual machines created under the main network 1. The ports comprise port 1, port 2, port … and port 3, and the virtual machines comprise virtual machine A, virtual machine B, … and virtual machine C. Virtual machine a is connected with port 1, virtual machine B is connected with port 2, and virtual machine C is connected with port 3, wherein port 1, port 2, …, and port 3 are connected with IPv4subnet 1, i.e. the IPv4 addresses on the ports all come from IPv4subnet 1. When an IPv4 network is created, the virtual machine A, the virtual machine B, … and the virtual machine C can communicate based on an IPv4 protocol.

The method and the related apparatus provided by the embodiments of the present application will be described in detail with reference to fig. 3 to 11, respectively. The method provided by the embodiment of the application can comprise data processing stages, wherein the data processing stages are used for determining the virtual machine identifier, acquiring first network protocol configuration information, determining a configuration file, acquiring a target network protocol address, adding the target network protocol address to the configuration file, distributing the target network protocol address to the virtual machine based on the configuration file, and the like. The implementation of each data processing stage can be seen in the following implementations shown in fig. 3 to 11.

Referring to fig. 3, fig. 3 is a schematic flowchart of a method for configuring a network protocol address according to an embodiment of the present disclosure. The method provided by the embodiment of the application can comprise the following steps 101 to 104:

101. the method comprises the steps of determining a virtual machine identification of the virtual machine, and inquiring first network protocol configuration information of the virtual machine from a database based on the virtual machine identification.

In some possible implementations, if the virtual machine belongs to a first network protocol subnet in the primary network, the virtual machine in the first network protocol subnet can communicate based on the first network protocol. Then, by determining the virtual machine identifier of the virtual machine, the first network protocol configuration information of the virtual machine may be queried from the database based on the virtual machine identifier, where the first network protocol configuration information includes a physical address of the virtual machine, a first network protocol address of the virtual machine, a network identifier of a host network to which the virtual machine belongs, and the like, which is not limited herein. Here, the first network protocol address is a network protocol address for performing communication based on the first network protocol, where the first network protocol may be an IPv4 protocol or an IPv6 protocol, and the like, which is not limited herein. It is understood that, when the first network protocol is the IPv4 protocol, the first network protocol address is the IPv4 address, the first network protocol configuration information is the IPv4 configuration information, and the first network protocol subnet is the IPv4 subnet; when the first network protocol is the IPv6 protocol, the first network protocol address is an IPv6 address, the first network protocol configuration information is IPv6 configuration information, and the first network protocol subnet is an IPv6 subnet. For convenience of description, in the embodiments of the present application, the first network protocol is an IPv4 protocol, the first network protocol address is an IPv4 address, the first network protocol configuration information is IPv4 configuration information, and the first network protocol subnet is an IPv4 subnet.

Specifically, since the virtual machine in the example of the present application is an online virtual machine which has already created an IPv4 network and is capable of normally running traffic, all information related to the creation of the IPv4 network is already stored in the database, that is, the IPv4 configuration information of all online virtual machines is stored in the database. By determining the virtual machine identification of the virtual machine, the IPv4 configuration information corresponding to the virtual machine identification can be inquired from the database based on the virtual machine identification. One virtual machine corresponds to one virtual machine identifier, and the virtual machine identifier is a character string generated when the virtual machine is created and used for uniquely marking the virtual machine, and the character string may be composed of numbers, characters and/or letters, which is not limited herein. The IPv4 configuration information may include a physical address of the virtual machine, an IPv4 address of the virtual machine, a network identifier of a main network (i.e., a network) to which the virtual machine belongs, an IPv4subnet identifier of an IPv4subnet (i.e., an IPv4subnet) to which the virtual machine belongs, a port identifier of a port (i.e., a port) bound by the virtual machine, and a port state, which are not limited herein.

102. And determining a configuration file corresponding to the network identifier.

In some possible embodiments, by obtaining the IPv4 configuration information of the virtual machine, the network identifier included in the IPv4 configuration information may be obtained, and based on the network identifier, a configuration file corresponding to the network identifier may be matched in the database. It can be understood that one network identifier corresponds to one configuration file, one configuration file includes a plurality of records, one record corresponds to one piece of configuration information of one virtual machine, and one piece of configuration information may be composed of one physical address, one virtual machine name, and one network protocol address. That is, all configuration information of all virtual machines included under one main network is stored in one configuration file.

For example, referring to fig. 4, fig. 4 is a schematic view of an application scenario of a configuration file provided in an embodiment of the present application. The network identifier of the configuration file as the master network is the configuration file corresponding to the network identifier 1, and the configuration file comprises 4 records, namely a first record, a second record, a third record and a fourth record. The data format of each record is "physical address, virtual machine name, network protocol address", and the network protocol addresses included in the first to fourth records in the figure are all the first network protocol addresses (i.e., IPv4 addresses).

103. And acquiring a target network protocol address, and adding the physical address and the target network protocol address into the configuration file.

In some possible embodiments, since the online virtual machine in the present application belongs to the first network protocol subnet (i.e., IPv4subnet) in the main network, if a second network protocol address needs to be configured for the online virtual machine, a second network protocol subnet needs to be created. The second network protocol subnet is a subnet in the main network, the virtual machines in the second network protocol subnet communicate based on the second network protocol, and the second network protocol is different from the first network protocol. Since the first network protocol in this embodiment of the application is an IPv4 protocol, the second network protocol is an IPv6 protocol, and when the second network protocol is an IPv6 protocol, the second network protocol address is an IPv6 address, the second network protocol configuration information is IPv6 configuration information, and the second network protocol subnet is an IPv6subnet (i.e., IPv6 subnet). Specifically, by obtaining the IPv6subnet address field and the IPv6subnet name, an IPv6subnet can be created. Here, the IPv6subnet can be regarded as an IPv6 address pool or an IPv6 address range, that is, the IPv6subnet includes a plurality of IPv6 addresses. In the embodiment of the application, since the addition of the second network protocol address (i.e., the IPv6 address) to the online virtual machine is implemented, the main network already exists, and only one IPv6subnet needs to be continuously created under the main network. That is, the IPv4subnet in which the virtual machine resides and the newly created IPv6subnet belong to the same main network. For example, referring to fig. 5, fig. 5 is a schematic view of an application scenario for creating an IPv6subnet under the same host network according to an embodiment of the present application. The created IPv4 network on the cloud platform comprises a main network 1, an IPv4subnet 1 created under the main network 1, ports and virtual machines. The ports comprise a port 1, a port 2, a port … and a port 3, the virtual machines comprise a virtual machine A, a virtual machine B, a virtual machine … and a virtual machine C, the virtual machine A is connected with the port 1, the virtual machine B is connected with the port 2, and the virtual machine C is connected with the port 3. Port 1, port 2, … and port 3 are connected to IPv4subnet 1, that is, the IPv4 addresses on the ports are all from IPv4subnet 1. As shown in fig. 5, the IPv6subnet 1 is created under the main network 1, and the IPv4subnet 1 and the IPv6subnet 1 belong to the same main network 1.

In some possible embodiments, after the IPv6subnet is created, the IPv6 address can be determined as the target network protocol address by randomly acquiring an unused IPv6 address from the created IPv6 subnet. And then adding the physical address of the virtual machine and the obtained IPv6 address into a configuration file corresponding to the main network to which the virtual machine belongs. Specifically, a configuration file corresponding to the network identifier may be searched or matched through the determined network identifier of the main network to which the virtual machine belongs, and by acquiring a data format of configuration information included in the configuration file, a piece of configuration information may be generated based on the data format and the determined virtual machine name, physical address of the virtual machine, and target network protocol address to establish a corresponding relationship between the physical address and the target network protocol address. That is, the determined virtual machine name, physical address, and target network protocol address may be added to the configuration file according to the data format described above. It will be appreciated that the above-described process of adding the physical address and the target network protocol address to the configuration file does not affect the normal operation of the online virtual machine.

For example, referring to fig. 6, fig. 6 is a schematic view of an application scenario of an update configuration file provided in an embodiment of the present application. The network identifier of the configuration file as the master network is the configuration file corresponding to the network identifier 1, and the configuration file comprises 4 records, namely a first record, a second record, a third record and a fourth record. The data format of each record is "physical address, virtual machine name, network protocol address", and the network protocol addresses included in the first to fourth records in the figure are all the first network protocol addresses (i.e., IPv4 addresses). If the physical address of the virtual machine to be configured is physical address 1, the virtual machine name is virtual machine name 1, and the target network protocol address is second network protocol address 1, the physical address 1, the virtual machine name 1, and the second network protocol address 1 may be added to the configuration file in the form of "physical address 1, virtual machine name 1, and second network protocol address 1" as a fifth record in the configuration file according to the data format "physical address, virtual machine name, and network protocol address".

104. And configuring the target network protocol address for the virtual machine according to the configuration file containing the target network protocol address.

In some possible embodiments, the process of adding the physical address and the target network protocol address to the configuration file is equivalent to adding a new piece of IPv6 configuration information in the configuration file, and the process is the same as a programmer writing source code in a development tool. But if the updated configuration file needs to be validated, the network protocol address configuration process, which may be a dnsmasq process, needs to be reset, just as the source code written by the programmer needs to be compiled first in the compiler. In an embodiment of the present application, the network protocol address configuration process may be reset based on the SIGKILL signal by acquiring the SIGKILL signal. Briefly, because the virtual machine is an online virtual machine capable of normally running a service, the network protocol address configuration process has been started, that is, a host network to which the virtual machine belongs has started a network protocol address configuration process to provide a DHCP service for the host network. Because the IPv4subnet to which the virtual machine belongs and the newly-built IPv6subnet belong to the same main network, and the network protocol address configuration process and the main network are in a one-to-one relationship, that is, one network protocol address configuration process can provide DHCP service for the virtual machines under all subnets in the same main network, the reset network protocol address configuration process needs to terminate the originally existing network protocol address configuration process first. In the embodiment of the present application, by obtaining a SIGKILL signal, the SIGKILL signal may immediately terminate an originally existing network protocol address configuration process, and then the cloud platform may immediately restart a network protocol address configuration process when it is monitored that the network protocol address configuration process abnormally exits, that is, reset the network protocol address configuration process.

In some possible embodiments, the updated configuration file may be validated by resetting the network protocol address configuration process. Therefore, when a network protocol address configuration request sent by the virtual machine is received, by analyzing the network protocol address configuration request, the physical address carried in the network protocol address configuration request and the address type of the requested network protocol address can be obtained, where the address type of the requested network protocol address is an IPv6 address, that is, the network protocol address configuration request is used to request to acquire a network protocol address (i.e., an IPv6 address) that communicates based on the second network protocol (i.e., an IPv6 protocol). Therefore, based on the reset network protocol address configuration process, and in combination with the physical address carried in the network protocol address configuration request and the updated configuration file, the target network protocol address corresponding to the physical address can be obtained from the updated configuration file, and the target network protocol address is sent to the virtual machine. Specifically, the network protocol address configuration process may obtain a target network protocol address (i.e., an IPv6 address) corresponding to the physical address of the virtual machine from the configuration file by searching for the configuration file corresponding to the network identifier, and then sending the target network protocol address to the virtual machine by parsing the configuration file. Based on this, the IPv4 address and the IPv6 address will exist on the virtual machine at the same time, and the implementation process of the above steps will not affect the operation of the virtual machine, that is, based on the method in the embodiment of the present application, the virtual machine can complete smooth transition from the IPv4 to the IPv4/IPv6 dual-protocol stack without interrupting the service.

For example, referring to fig. 7, fig. 7 is a schematic view of an application scenario of a configuration method of a network protocol address provided in an embodiment of the present application. Assuming that the virtual machine is a virtual machine C, the steps are as follows: s01, acquiring the physical address of the virtual machine C from the database based on the virtual machine identifier; s02, acquiring an IPv6 address from the IPv6subnet 1, and adding the IPv6 address, the physical address and the virtual machine name into a configuration file; s03, resetting a network protocol address configuration process; s04, acquiring a network protocol address configuration request of the virtual machine C; s05, the network protocol address configuration process obtains the IPv6 address corresponding to the physical address of the virtual machine C from the configuration file, and sends the IPv6 address to the virtual machine C. Based on the method, the virtual machine C can be continuously allocated to the IPv6 address on the basis of owning the IPv4 address. In other words, the implementation based on the above steps S01-S05 can realize that the virtual machine C has the IPv4/IPv6 dual-protocol stack without interrupting the service, that is, the connection is established between the IPv6subnet 1 and the port 3.

Further, if all the virtual machines under the IPv4subnet pass through the above configuration process of the IPv6 address, it can be realized that each virtual machine can own the IPv4/IPv6 dual-protocol stack without interrupting the service. For example, referring to fig. 8, fig. 8 is a schematic system architecture diagram of an IPv4/IPv6 network provided by the embodiment of the present application. The IPv4/IPv6 network in the embodiment of the present application is created on a cloud platform, and includes a main network 1, an IPv4subnet 1, an IPv6subnet 1, a port, and a virtual machine, which are created under the main network 1. The ports comprise a port 1, a port 2, a port … and a port 3, the virtual machines comprise a virtual machine A, a virtual machine B, a virtual machine … and a virtual machine C, the virtual machine A is connected with the port 1, the virtual machine B is connected with the port 2, and the virtual machine C is connected with the port 3. Port 1, port 2, …, port 3 are all connected to IPv4subnet 1 and IPv6subnet 2, respectively. That is to say, the IPv4 addresses on the ports all come from the IPv4subnet 1, and the IPv6 addresses on the ports all come from the IPv6subnet 1, that is, the virtual machine a, the virtual machine B, and the virtual machine … of the IPv4/IPv6 network are built, and the virtual machine C can communicate based on the IPv4 protocol and also can communicate based on the IPv6 protocol.

According to the configuration method of the network protocol address provided by the embodiment of the application, by determining the virtual machine identifier of the virtual machine, the first network protocol configuration information (i.e., IPv4 configuration information) of the virtual machine can be queried from the database based on the virtual machine identifier, where the first network protocol configuration information at least includes a physical address of the virtual machine, a first network protocol address (i.e., IPv4 address) of the virtual machine, and a network identifier of a host network to which the virtual machine belongs. Determining a configuration file corresponding to the network identifier, adding the physical address and the target network protocol address to the configuration file by acquiring the target network protocol address (namely the IPv6 address), and then enabling the network protocol address configuration process to configure the target network protocol address for the virtual machine according to the configuration file containing the target network protocol address by resetting the network protocol address configuration process. By adopting the embodiment of the application, the online virtual machine can be smoothly upgraded from IPv4 to IPv4/IPv6 dual-protocol stack, the upgrading cost is reduced, and the applicability is strong.

Referring to fig. 9, fig. 9 is another schematic flowchart of a method for implementing an IPv4/IPv6 dual stack according to an embodiment of the present application. The method provided by the embodiment of the application can comprise the following steps 201 to 204:

201. the method comprises the steps of determining a virtual machine identification of the virtual machine, and inquiring first network protocol configuration information of the virtual machine from a database based on the virtual machine identification.

202. And determining a configuration file corresponding to the network identifier.

203. And acquiring a target network protocol address, and adding the physical address and the target network protocol address to a configuration file corresponding to the network identifier.

204. And configuring the target network protocol address for the virtual machine according to the configuration file containing the target network protocol address.

For a specific implementation manner of the foregoing step 201 to step 204, reference may be made to the description of step 101 to step 104 in the embodiment corresponding to fig. 3, which is not described herein again.

205. When the virtual machine is closed and restarted and the configuration information in the configuration file is emptied, obtaining the historical configuration information of the virtual machine from the database and adding the historical configuration information to the configuration file.

In some possible embodiments, when the cloud platform is turned off and restarted or the virtual machine is turned off and restarted, the configuration file configuration information is disappeared or emptied, so that for convenience of subsequent use and efficiency of configuring the network protocol address for the virtual machine, the information including the physical address, the target network protocol address (i.e., the IPv6 address), and the network identifier may be stored in the database as a piece of historical configuration information. That is, an IPv6 configuration message is generated according to the physical address of the virtual machine, the target network protocol address and the network identifier of the network to which the virtual machine belongs, and the IPv6 configuration message is updated to the database. Therefore, when the cloud platform is restarted next time, the cloud platform can read the configuration information in the database and write the configuration information into the configuration file, so that when the virtual machine requests the network protocol address, the network protocol address configuration process can find the network protocol address corresponding to the physical address in the configuration file according to the physical address of the virtual machine, and the virtual machine is continuously leased.

According to the configuration method of the network protocol address provided by the embodiment of the application, by determining the virtual machine identifier of the virtual machine, the first network protocol configuration information (i.e., IPv4 configuration information) of the virtual machine can be queried from the database based on the virtual machine identifier, where the first network protocol configuration information at least includes a physical address of the virtual machine, a first network protocol address (i.e., IPv4 address) of the virtual machine, and a network identifier of a host network to which the virtual machine belongs. Determining a configuration file corresponding to the network identifier, adding the physical address and the target network protocol address to the configuration file by acquiring the target network protocol address (namely the IPv6 address), and then enabling the network protocol address configuration process to configure the target network protocol address for the virtual machine according to the configuration file containing the target network protocol address by resetting the network protocol address configuration process. And finally, storing the IPv6 configuration information comprising the physical address, the target network protocol address and the network identifier in a database, and updating the configuration record in the database. By adopting the embodiment of the application, the online virtual machine can be smoothly upgraded from IPv4 to IPv4/IPv6 dual-protocol stack, the upgrading cost is reduced, and the applicability is strong.
