[0055] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] An embodiment of the present application provides a network card configuration method, which is applied to a network card configuration device. Referring to Figure 1 as shown, the method includes the following steps:

[0057] Step 101, obtain a target configuration file corresponding to a target virtual machine.

[0058] Among them, the target configuration file is configured with configuration parameters for providing a target virtual physical function for the target virtual machine, and the target virtual physical function is obtained by splitting the reference physical function of the target network card in advance.

[0059] In the embodiment of the present application, the network card configuration device is a device that can install the target network card and provide cloud computing services. For example, it can be a computer device, a server, etc. with high computing power. The network card configuration device can run a virtual machine. The target network card is a low-latency network card, such as a Solarflare network card. The target configuration file can be a file obtained by a user configuring parameters for the login process of the target virtual machine when logging in to the target virtual machine. The target configuration file is configured with the target virtual physical function configured by the user for the target virtual machine. The virtual physical function (Physical Function, PF) can also be called a virtual network interface. The virtual physical function is obtained by splitting the reference physical function of the target network card, and the reference physical function is a physical function of the target network card, that is, a physical network interface of the target network card.

[0060] Step 102, allocate the target virtual physical function to the target virtual machine based on the target configuration file.

[0061] Among them, based on the target configuration file, the target virtual physical function is allocated to the target virtual machine, so that the target virtual machine can realize data transmission with the Internet through the target virtual physical function.

[0062] In an embodiment of the present application, after the network card configuration device obtains the target configuration file for the target virtual machine, it allocates the target virtual physical function to the target virtual machine according to the configuration parameters in the target configuration file. Among them, the network card configuration device can analyze the configuration parameters in the target configuration file to determine whether the target virtual physical function has been allocated to other virtual machines. If the target virtual physical function has been allocated to other virtual machines, a prompt message can be generated to prompt the user that the target virtual physical function has been used. In this way, the user can reconfigure the target virtual machine. However, in some application scenarios, when the user configures the target configuration file, the network card configuration device can only display the virtual physical functions that are not currently allocated, so that the user can select the target virtual physical function from the unallocated virtual physical functions. The target virtual physical function includes at least one virtual physical function.

[0063] The network card configuration method provided by the embodiment of the present application obtains the target configuration file corresponding to the target virtual machine, and based on the target configuration file, allocates the target virtual physical function to the target virtual machine, so as to enable the target virtual machine to realize data transmission with the Internet through the target virtual physical function. In this way, by allocating the target virtual physical function to the target virtual machine to realize data transmission between the target virtual machine and the Internet, the problem that the use range of the low-latency network acceleration scheme implemented by current low-latency network cards such as Solarflare network cards is small is solved, the use range of the low-latency network acceleration scheme implemented by low-latency network cards such as Solarflare network cards is expanded, and the use efficiency of the low-latency network acceleration scheme implemented by low-latency network cards such as Solarflare network cards is improved.

[0064] Based on the foregoing embodiment, an embodiment of the present application provides a network card configuration method. Refer to Figure 2 As shown, this method is applied to a network card configuration device, and this method includes the following steps:

[0065] Step 201, obtain the target configuration file corresponding to the target virtual machine.

[0066] Among them, the target configuration file is configured with configuration parameters for providing the target virtual physical function for the target virtual machine, and the target virtual physical function is obtained by slicing the reference physical function of the target network card in advance.

[0067] In an embodiment of the present application, the user sets configuration parameters for the target virtual machine to obtain the target configuration file. In this way, the network card configuration device can obtain the target configuration file corresponding to the target virtual machine.

[0068] Step 202, based on the target configuration file, determine the LAN MAC address of the target virtual physical function.

[0069] In the embodiment of the present application, the network interface name of the target virtual physical function is configured in the target configuration file. In this way, the network interface configuration device can determine the network interface name of the target virtual physical function from the target configuration file, and then determine the MAC address of the target virtual physical function according to the network interface name of the target virtual physical function.

[0070] Step 203: Determine that the MAC address of the target virtual machine is the MAC address of the target virtual physical function.

[0071] In the embodiment of the present application, on the premise that the MAC address of the target virtual physical function is not currently allocated, the MAC address of the target virtual machine is set as the MAC address of the target virtual physical function. In this way, it is realized that the target virtual machine performs data transmission through the target virtual physical function.

[0072] Based on the foregoing embodiments, in other embodiments of the present application, as shown in Figure 3 After the network card configuration device executes step 203, it is further used to execute step 204:

[0073] Step 204: Perform a locking operation on the MAC address of the target virtual physical function.

[0074] Among them, performing a locking operation on the MAC address of the target virtual physical function enables the MAC address of the target virtual physical function to provide network communication services only for the target virtual machine.

[0075] In the embodiment of the present application, a locking operation is performed on the MAC address of the target virtual physical function to prevent the MAC address of the target virtual function from being re-allocated to other virtual machines or devices, resulting in a conflict in the use of physical functions.

[0076] Based on the foregoing embodiments, in other embodiments of the present application, as shown in Figure 4 Before the network card configuration device executes step 201, it is further used to execute steps 205 to 207:

[0077] Step 205: Obtain physical function configuration parameters.

[0078] In the embodiment of the present application, the physical function configuration parameters are configured with a reference physical function that needs to perform physical function slicing virtualization, and a preset number of virtual physical functions that need to be sliced out, that is, the user needs to set which physical function of the target network card to perform physical function slicing virtualization operations, and the number of slices required.

[0079] Step 206: Determine the reference physical function of the target network card that needs to perform physical function slicing virtualization from the physical function configuration parameters.

[0080] In an embodiment of the present application, the network card configuration device analyzes the physical function configuration parameters to determine the reference physical function of the target network card that needs to perform physical function slicing and virtualization. Exemplarily, the target network card is a Solarflare network card, and the reference physical function of the target network card specified in the corresponding physical function configuration parameters that needs to perform physical function slicing and virtualization is Network Interface 1 of the Solarflare network card.

[0081] Step 207: Based on the reference physical function, slice out a preset number of reference virtual physical functions.

[0082] Among them, the physical function configuration parameters include a preset number, and the preset number of reference virtual physical functions include the target virtual physical function.

[0083] In an embodiment of the present application, the preset number is a number greater than or equal to 1 set by the user according to actual needs. Exemplarily, if the preset number is 3, then for the reference physical function, 3 reference virtual physical functions are sliced out, including Reference Virtual Physical Function 1, Reference Virtual Physical Function 2, and Reference Virtual Physical Function 3.

[0084] Based on the foregoing embodiments, in other embodiments of the present application, as shown in Figure 5 After the network card configuration device executes step 207, it is further used to execute steps 208 to 210:

[0085] Step 208: Determine the historical network interface sorting order.

[0086] In an embodiment of the present application, the historical network interface sorting order can be recorded in the network card rule file. In this way, the network card rule file recording the historical network interface sorting order can be determined.

[0087] Step 209: Name the preset number of reference virtual physical functions according to the preset network interface naming rule to obtain the preset number of reference network interface names.

[0088] In an embodiment of the present application, the preset network interface naming rule is used to specify the rule for naming virtual physical functions. For example, it can be named according to the naming of the corresponding physical function, so as to indicate the relationship between the virtual physical function and the corresponding physical function. Exemplarily, assuming that the naming of Network Interface 1 is eth3, the naming of the corresponding 3 reference virtual physical functions is eth31, eth32, and eth33.

[0089] Step 210: Sort the preset number of reference network interface names starting from the last sorting object in the historical network interface sorting order according to the preset sorting rule to obtain the target network interface sorting order.

[0090] In the embodiment of the present application, the preset sorting rule is from bottom to top, from left to right, with optical ports first and then electrical ports. In this way, according to the preset sorting rule, a preset number of reference network port names are sorted to the end of the historical network port sorting order to obtain the target network port sorting order. Exemplarily, if the historical network port sorting order is eth1, eth2, eth3, eth4, eth5, then eth31, eth32, and eth33 are sorted after eth5, and the target network port sorting order obtained is eth1, eth2, eth3, eth4, eth5, eth32, eth31, eth33.

[0091] Based on the foregoing embodiments, in other embodiments of the present application, referring to Figure 6 as shown, after the network card configuration device executes step 209, it is further configured to execute step 211:

[0092] Step 211: Hide a preset number of reference network port names.

[0093] In the embodiment of the present application, in the network card configuration device, the preset number of reference network port names obtained by splitting are subjected to a hiding process, reducing the confusion caused by users seeing these reference network port names and improving the user experience effect. Specifically, the virtual function input / output (VFIO) technology can be used to transfer the virtual physical function from the kernel state to the user state, thereby implementing the hiding operation. It should be noted that step 211 can be executed before step 210, after step 210, or simultaneously with step 210, and the specific execution order can be determined according to the actual situation.

[0094] Based on the foregoing embodiments, in other embodiments of the present application, referring to Figure 7 as shown, after the network card configuration device executes step 210, it is further configured to execute step 212:

[0095] Step 212: Send the target network port sorting order to the target virtual machine.

[0096] Among them, the target network port sorting order is used for display in the target virtual machine to enable the user to perform a selection operation.

[0097] In the embodiment of the present application, the network card configuration device sends the determined target network port sorting order to the target virtual machine. In this way, when the user operates on the target virtual machine, the corresponding network port names can be seen. The target virtual machine can also distinguish the physical function and the virtual physical function according to the network port names in the received target network port sorting order.

[0098] Based on the foregoing embodiments, in other embodiments of the present application, referring to Figure 8As shown, after the network card configuration device executes step 212, it is further used to execute steps 213 to 215:

[0099] Step 213, establish an association relationship between the reference physical function and a preset number of reference virtual physical functions.

[0100] In the embodiment of the present application, the association relationship between the reference physical function and a preset number of reference virtual physical functions may be a correspondence relationship between the reference physical function and a preset number of reference virtual physical functions.

[0101] Step 214, count the allocation information of a preset number of reference virtual physical functions.

[0102] In the embodiment of the present application, the allocation information of a preset number of reference virtual physical functions refers to the usage status of a preset number of reference virtual physical functions being allocated for use. The allocation information at least includes information about the virtual machines used and the identification information of the reference virtual physical functions being used. The information about the virtual machines includes virtual machine identification information, and the identification information of the reference virtual physical functions includes at least one of the following information: the corresponding Peripheral Component Interconnect (PCI) address, MAC address, etc.

[0103] Step 215, store the association relationship and the allocation information.

[0104] In the embodiment of the present application, the association relationship and the allocation information are stored correspondingly, so as to determine the number of reference virtual physical functions being used, which virtual machines are using the corresponding reference virtual physical functions, and the reference virtual physical functions that have not been used yet.

[0105] Based on the foregoing embodiments, the embodiment of the present application provides an implementation logic structure diagram of a network card configuration device. Refer to Figure 9 As shown, it includes: a Solarflare network card, virtual machine 1, and virtual machine 2. Among them, the slicing virtualization technology of the Solarflare network card is used to slice the Solarflare network card into n virtual physical functions, denoted as PF1, PF2,..., PFn. Among them, PF1 is passed through to virtual machine 1 for use, and PFn is passed through to virtual machine 2 for use. The application programs in virtual machine 1 and virtual machine 2 can both be transformed by using acceleration suites of the Solarflare network card, such as Onload, Transmission Control Protocol Direct (TCPDirect), TCPDirect, EF_VI, etc.

[0106] Among them, to implement Figure 9The implementation process between virtual machine 1 and PF1, virtual machine 2 and PF2 in the network card configuration device shown can refer to Figure 10 As shown, the network card configuration device includes a physical function management module and a virtual machine associated physical function module; wherein:

[0107] The physical function management module is used to implement the following processes:

[0108] Step 301: The physical function management module backs up the network card rule file of the network card included in the network card configuration device.

[0109] The network card rule file includes the sorting order of the current network cards of the network card configuration device.

[0110] Step 302: The physical function management module performs network card segmentation virtualization through the Solarflare network card's own tool.

[0111] The physical function management module uses the Solarflare network card's built-in tool to perform a network card virtualization operation on a physical PF of the Solarflare network card, and divides a specified number of virtual PFs. Figure 11 Configure the parameters on the page shown, set the eth10 physical PF of the Solarflare network card to perform network card switching virtualization operation, and split out 7 virtual PFs.

[0112] Step 303: The physical function management module controls the network card configuration device to restart.

[0113] Step 304: After the network card configuration device is restarted, the physical function management module enters the PF network card sequence preservation process.

[0114] Among them, since there is no obvious difference between virtual PF and physical PF, it is easy for virtual PF to occupy the PCI address space of physical PF and squeeze out the names and sorting order of other types of network cards. Therefore, the physical function management module needs to enter the PF network card order preservation process: control the driver of the Solarflare network card, that is, the virtual PF of the Solarflare network card to start last, so as not to squeeze out the PCI address space and network card name order of other types of network cards; or, sort the split virtual PF into the sorting order included in the network card rule file, and use the naming requirements of the virtual PF to name the corresponding network card, thereby solving the crowding problem of the same type of network cards.

[0115] Step 305: The physical function management module executes the hidden function of the virtual PF.

[0116] Among them, since there is no difference between the virtual PF and the physical PF, if multiple generated virtual PFs exist in the network subsystem, there will be problems in management and maintenance. For example, users will see multiple network interface names, causing confusion and resulting in a poor user experience. Therefore, the VFIO technology can be used to transfer the virtual PF driver from the kernel mode to the user mode, so as to achieve the purpose of hiding.

[0117] Step 306: The physical function management module maintains the mapping relationship table of the physical PF and the virtual PF and writes it into a file.

[0118] Among them, the file records the usage situation of the virtual PF, including how many virtual PFs are used, which virtual machine each virtual PF is used by, and how many virtual PFs are left available. In addition, it also includes the configuration information related to each virtual PF, such as its corresponding PCI address, MAC address, device identifier, etc.

[0119] The virtual machine associated physical function module is mainly used to implement the following processes:

[0120] Step 401: The virtual machine associated physical function module controls the startup of the virtual machine.

[0121] Step 402: The virtual machine associated physical function module selects a virtual PF.

[0122] Step 403: The virtual machine associated physical function module determines the MAC address of the selected virtual PF from the file of the physical function management module.

[0123] Step 404: The virtual machine associated physical function module assigns the determined MAC address to the virtual machine.

[0124] Step 405: The virtual machine associated physical function module updates the virtual machine to which the virtual PF used this time has been assigned into the file.

[0125] Among them, a locking operation is performed on the MAC address of the virtual PF assigned to the virtual machine to ensure that there will be no conflict when multiple virtual machines call the same virtual PF. Exemplarily, the interface for the virtual machine to select the network card can be as Figure 12 shown. First step: Configure the network interface that the virtual machine needs to connect at area A1. Second step: Select the network card model at area A2. For example, the split virtual network card model can adopt the "SR direct pass-through network card". At this time, the SR direct pass-through network card can be selected. Third step: Area A3 is the network interface list. The network interface list shows the available idle direct pass-through network interfaces. If the SR direct pass-through network card function is selected, two options displayed at area A4 need to be selected simultaneously for configuration.

[0126] It should be noted that for the explanations of the same steps or concepts in this embodiment and other embodiments, reference can be made to the descriptions in other embodiments, and details will not be elaborated here.
