technical field

Background technique

With the rapid development of cloud computing technology, cloud computing service platforms of major manufacturers at home and abroad have also begun to be used in many fields such as science, education, culture, health, government, high-performance computing, e-commerce, and the Internet of Things. The virtual machine is the foundation of cloud computing technology. Users use the computing resources of the cloud computing service platform through the virtual machine. With the continuous increase of users of the cloud computing service platform, it is necessary to create a large number of virtual machines to meet the needs of users.

After the virtual machine is created, the corresponding application program needs to be deployed on the virtual machine for users to perform corresponding services. Before deploying the application program, it is necessary to configure an IP address for the virtual machine so that the virtual machine can connect to the network.

At present, the method for configuring the IP address of a virtual machine is mainly to manually configure the IP address of each virtual machine by an administrator. After the virtual machine is created, the administrator logs in to the virtual machine and sets the IP address of the virtual machine.

Due to the huge number of virtual machine users, many virtual machines are generally created at the same time when creating a virtual machine. If the administrator manually configures the IP address of the virtual machine, the administrator needs to log in to each virtual machine in turn and set each virtual machine separately. The IP address of the virtual machine needs a lot of time for the administrator to manually configure the IP address of the virtual machine, and the efficiency of the IP address assignment of the virtual machine is low.

The embodiment of the present invention provides a method for assigning a virtual machine IP address. After receiving the instruction for assigning an IP address, a management instruction is generated. According to the management instruction, a service network is determined for the service virtual machine, and the service network is connected to the service network through the service network.

In one embodiment of the present invention, the MAC addresses of the network cards of the service virtual machines to be assigned IP addresses are obtained through the target service network, and an IP address is allocated to each MAC address, wherein the IP addresses corresponding to each MAC address are different. Form the allocation instruction binding MAC address and IP address, and send each allocation instruction to the service virtual machine corresponding to the MAC address through the target service network, and the service virtual machine obtains the corresponding IP address according to the received allocation instruction, so as to realize the virtual machine IP The allocation of addresses, in this way, can ensure that the IP addresses of the network cards of each virtual machine are different, avoiding the occurrence of abnormal networking of virtual machines due to the same IP address, and improving the accuracy of IP address allocation of virtual machines.

In order to make the purpose, technical solution and advantages of the present invention more clear, the method for allocating virtual machine IP addresses will be further described in detail below in conjunction with the system for allocating virtual machine IP addresses provided by the embodiment of the present invention shown in FIG. 1 .

As shown in Figure 4, an embodiment of the present invention provides a method for assigning a virtual machine IP address, including:

Step 401: the network management module receives an external IP address assignment instruction;

In one embodiment of the present invention, when the new virtual machine needs to be allocated an IP address after the creation of the new virtual machine is completed, the user sends an IP address allocation instruction to the network management module. For example, 100 virtual machines are newly created, namely virtual machine 1 to virtual machine 100, and the user sends an instruction to the network management module to allocate IP addresses for the 100 virtual machines.

Step 402: The network management module judges whether there is a network virtual machine whose number of Ethernet service ports has not reached the saturation state, if yes, execute step 403, otherwise execute step 404;

In one embodiment of the present invention, the maximum number of Ethernet service ports corresponding to each network virtual machine is set, and when the number of Ethernet service ports corresponding to the network virtual machine reaches the maximum number, the Ethernet service ports corresponding to the network virtual machine If the number of network service ports reaches saturation, the network management module judges whether there is a network virtual machine whose number of Ethernet service ports has not reached saturation. To create a service network on the existing network virtual machine, correspondingly execute step 403. If it does not exist, it means that the existing network virtual machine cannot be configured with an Ethernet service port, and a new network virtual machine needs to be created, and correspondingly execute step 404. For example, set the maximum number of Ethernet service ports corresponding to the network virtual machine to 5. There are currently two network virtual machines connected to the network management module through the management network, namely network virtual machine 1 and network virtual machine 2. If the network virtual machine There are five Ethernet service ports on both machine 1 and network virtual machine 2. Since the number of Ethernet service ports corresponding to network virtual machine 1 and network virtual machine 2 is saturated, the current network virtual machine cannot Service ports, correspondingly execute step 404, if the number of Ethernet service ports set on the network virtual machine 1 is 5, and the number of Ethernet service ports set on the network virtual machine 2 is 3, because the network virtual machine 2. The number of corresponding Ethernet service ports has not reached the saturation state, and the Ethernet service ports can be continued to be set on the network virtual machine 2, and step 403 is executed correspondingly.

Step 403: Taking the network virtual machine whose number of Ethernet service ports is not saturated as the target network virtual machine, the network management module sends a management instruction to the target network virtual machine, and executes step 405;

In one embodiment of the present invention, if each network virtual machine currently connected to the network management module includes a network virtual machine whose number of corresponding Ethernet service ports has not reached a saturated state, the network virtual machine whose number of Ethernet service ports has not reached a saturated state The network virtual machine serves as the target network virtual machine, and the network management module sends a management command to the target network virtual machine according to the received external IP address assignment command, and executes step 405 accordingly. For example, the number of Ethernet service ports set on the network virtual machine 2 is 3, and the number of Ethernet service ports corresponding to the network virtual machine 2 is not saturated, and the network virtual machine 2 is used as the target network virtual machine. The module sends a management instruction to allocate IP addresses for 100 virtual machines to the network virtual machine 2.

Step 404: the network management module creates a new network virtual machine, uses the newly created network virtual machine as a target network virtual machine, and sends a management instruction to the target network virtual machine.

In one embodiment of the present invention, if the number of Ethernet service ports corresponding to each network virtual machine currently connected to the network management module reaches a saturated state, the network management module creates a new network virtual machine as the target network virtual machine, which The newly created network virtual machine is connected to the network management module through its own Ethernet management port and management network. After the creation is completed, the network management module sends a management command to the target network virtual machine. For example, five Ethernet service ports are set on both network virtual machine 1 and network virtual machine 2, and the number of Ethernet service ports corresponding to network virtual machine 1 and network virtual machine Or set a new Ethernet service port on the network virtual machine 2, and the network management module creates a new network virtual machine 3 as the target network virtual machine, and the network virtual machine 3 is connected to the management network through its own Ethernet management port, and then connected to the network The management modules are connected, and after the network virtual machine 3 is created, the network management module sends a management command to the network virtual machine 3 to allocate IP addresses for 100 virtual machines.

Step 405: The target network virtual machine creates a target service network connected to its Ethernet service port according to the management instruction.

In one embodiment of the present invention, after the target network virtual machine receives the management instruction sent by the network management module, according to the management instruction, create a target service network connected to it, and set a new Ethernet service port on itself, The newly created target service network is connected to the target network virtual machine through the newly set Ethernet service port. For example, for the convenience of description, the network virtual machine 2 whose number of Ethernet service ports has not reached saturation and the newly created network virtual machine 3 are collectively referred to as network virtual machine 4, and a new service network created by network virtual machine 4 1. The network virtual machine 4 sets a new Ethernet service port on itself, and the service network 1 is connected to the network virtual machine 4 through the Ethernet service port.

Step 406: The target network virtual machine adds a virtual machine port group to the target service network, and connects the network card of the service virtual machine to be assigned an IP address to the virtual machine port group.

In one embodiment of the present invention, after the target network virtual machine has created the target service network, the target network virtual machine adds a virtual machine port group on the target service network according to the management instruction sent by the network management module, and the number of virtual machine port groups The number of service virtual machines is the same. After the virtual machine port group is added, connect the virtual machine port group to the network card of the service virtual machine. A virtual machine port group corresponds to a network card of a service virtual machine. For example, network virtual machine 4 adds 100 virtual machine port groups to service network 1 according to the management instruction sent by the network management module to assign IP addresses to 100 virtual machines, which are respectively virtual machine port group 1 to virtual machine port group 100. Each virtual machine from virtual machine 1 to virtual machine 100 includes a network card. Connect virtual machine port group 1 to virtual machine port group 100 to the network cards of virtual machine 1 to virtual machine 100 respectively. Each virtual machine port group Corresponding to one virtual machine, connect 100 virtual machines to the service network through their respective network cards and corresponding virtual machine port groups.

Step 407: The network management module selects a corresponding number of unoccupied IP addresses from its own IP address library and sends them to the target network virtual machine, and marks the selected unoccupied IP addresses as occupied.

In one embodiment of the present invention, the network management module includes an IP address library, and the IP address library includes all occupied IP addresses and unoccupied IP addresses, and the network management module selects from the IP address library the IP address virtual address to be allocated. The number of unoccupied IP addresses with the same number of network cards on the machine will be sent to the target network virtual machine through the management network. After the sending is completed, the network management module will mark the selected unoccupied IP addresses as occupied Occupied. For example, the network management module selects 100 unoccupied IP addresses from the IP address library, which are IP address 1 to IP address 100, and sends these 100 unoccupied IP addresses to the network virtual machine 4. After the sending is completed , the network management module identifies the 100 unoccupied IP addresses as already occupied.

Step 408: The target network virtual machine obtains the MAC addresses of the network cards of each service virtual machine, and assigns an IP address to each MAC address, forming an assignment instruction for binding the MAC address and the IP address.

In one embodiment of the present invention, the target network virtual machine obtains the MAC address of the network card of each service virtual machine through the target service network, and distributes the IP address sent by the network management module to each MAC address, and each MAC address corresponds to an IP address , binding each MAC address and its paired IP address to form an allocation instruction for binding the MAC address to the IP address. For example, network virtual machine 4 obtains the MAC addresses of each network card on virtual machine 1 to virtual machine 100 through the target service network, and obtains a total of 100 MAC addresses, which are respectively MAC address 1 to MAC address 100, corresponding to virtual machines 1 to 100 respectively. The network card on the virtual machine 100 assigns the 100 IP addresses sent by the network management module to each of the 100 MAC addresses. MAC addresses 1 to 100 correspond to IP addresses 1 to 100 respectively. The paired MAC addresses and IP addresses are bound to form an allocation instruction binding MAC address and IP address, MAC address 1 is bound to IP address 1 to form allocation instruction 1, MAC address 2 is bound to IP address 2 to form allocation instruction 2, ..., MAC Address 100 is bound with IP address 100 to form allocation instruction 100 .

Step 409: the target network virtual machine sends each allocation instruction to the corresponding service virtual machine.

In an embodiment of the present invention, the target network virtual machine sends each allocation command to the service virtual machine where the network card corresponding to the MAC address is located through the target service network according to the MAC address corresponding to each allocation command. For example, the network virtual machine 4 sends the allocation instruction 1 to the virtual machine 1 where the network card corresponding to the MAC address 1 is located through the target service network, and sends the allocation instruction 2 to the virtual machine 2 where the network card corresponding to the MAC address 2 is located, ..., The allocation instruction 100 is sent to the virtual machine 100 where the network card corresponding to the MAC address 100 is located.

Step 410: The service virtual machine obtains the corresponding IP address according to the allocation instruction sent by the target network virtual machine.

In one embodiment of the present invention, each service virtual machine obtains the IP address in the area according to the allocation instruction after receiving the assignment instruction sent by the target virtual machine, and sets the IP address as the IP address of the corresponding network card. For example, virtual machine 1 obtains IP address 1 after receiving allocation instruction 1 sent by network virtual machine 4, and sets IP address 1 as the IP address of the network card of virtual machine 1; 4 After the allocation command 2 is sent, obtain the IP address 2 from it, and set the IP address 2 as the IP address of the network card of the virtual machine 2; ...; after the virtual machine 100 receives the allocation command 100 sent by the network virtual machine 4 , obtain the IP address 100 from it, and set the IP address 100 as the IP address of the network card of the virtual machine 100.

It should be noted that when the service virtual machine stops using and releases the IP address, the network virtual machine releases the binding between the MAC address and the IP address of the network card of the virtual machine whose IP address is to be released, and the network management module releases the bound IP address Identified as unused.

It should be further noted that the management network and the service network may be separated into different network segments, or may use the same segment of subnet.

According to the above solution, a system and method for assigning a virtual machine IP address and a network virtual machine provided in the embodiments of the present invention have at least the following beneficial effects:

In the embodiment of the present invention, the network management module is connected to at least one network virtual machine through the management network, each network virtual machine is connected to at least one service network, and each service network is connected to at least one service virtual machine. When the network management module After receiving the instruction of sub-virtual machine IP address, the management instruction is sent to the network virtual machine through the management network. After receiving the management instruction, the network virtual machine determines the service network connected to it, and each service virtual machine is connected to the service network. The virtual machine allocates IP addresses for each service virtual machine connected to the service to form an allocation instruction. The network virtual machine sends the allocation instruction to each service virtual machine through the service network, and each service virtual machine obtains the corresponding IP address according to the received allocation instruction. In this way, after receiving the IP address assignment command, the IP address is automatically assigned to each virtual machine, and there is no need to manually log in to each virtual machine to set up, which improves the IP address of the virtual machine.
