[0039] Business data traffic refers to the data traffic generated during the operation of an enterprise, which is mainly used for communication, networks, and related data value-added services. Due to the complexity of this business data traffic, it is usually necessary for the virtual machines corresponding to the servers to process it. Therefore, according to different business processing requirements, the switching or switching between virtual machines is particularly important. In the related art, when it is necessary to switch virtual machines, it is necessary to pause receiving business data traffic. After manually configuring and switching the virtual machine to be switched, the business data traffic is received and processed again.

According to the switching permission signal, the business data traffic is sent to the virtual machine to be switched for processing, without pausing the reception and processing of the business data traffic, and manually configuring and switching the virtual machine to be switched, thus ensuring the continuity of business traffic processing.

[0041] To enable those skilled in the art of the present technology to better understand the solution of this application, the following further elaborates on this application in combination with the accompanying drawings and specific implementation manners.

[0042] In combination with the specific application environment architecture or specific hardware architecture on which the execution of the switching processing method of the virtual machine depends, the specific application environment architecture or specific hardware architecture is described herein. Refer to Figure 1 , Figure 1 which is a schematic diagram of the application scenario of the switching processing method of the virtual machine.

[0043] As Figure 1 shown, the electronic device in this scenario includes: server 10 and client 20.

[0044] Server 10 can be an independent server or a cluster composed of multiple servers.

[0045] Among them, server 10 at least includes: a network interface, a target virtual machine, a virtual machine to be switched, a redirection layer, and a synchronization engine.

[0046] Client 20 can be a display terminal or other user terminals.

[0047] Server 10 receives the service data traffic transmitted by the network interface; sends the service data traffic to the initialized target virtual machine so that the target virtual machine processes the service data traffic; according to the instruction of client 20, completes the initialization of the virtual machine to be switched according to the pre-generated driver loading notification; after the initialization of the virtual machine to be switched, sends a switching prompt to the synchronization engine so that the synchronization engine obtains the running data of the target virtual machine according to the switching prompt, copies the running data to the virtual machine to be switched, and generates a switching permission signal; receives the switching permission signal sent by the synchronization engine; according to the switching permission signal, sends the service data traffic to the virtual machine to be switched so that the virtual machine to be switched processes the service data traffic.

[0048] Figure 2 is a flow schematic of the switching processing method of the virtual machine provided by the embodiment of this application Figure 1 ,As Figure 2 shown, the embodiment of this application provides a switching processing method of a virtual machine, and the method is described in detail as follows:

[0049] S201: Receive the service data traffic transmitted by the network interface.

[0050] In this embodiment, the service data traffic is I / O traffic. I / O traffic refers to the amount of data flowing in the server system during input / output operations. I / O is the abbreviation of input / output, representing the process of data transmission between different locations in a computer. Specifically, I / O traffic involves the process of data being read from an external device into memory or being output from memory to an external device.

[0051] S202: Send the service data traffic to the initialized target virtual machine so that the target virtual machine processes the service data traffic.

[0052] In this embodiment, the initialization process of the target virtual machine specifically includes steps a to f:

[0053] Step a: Receive a driver loading notification sent by a preset first driver.

[0054] Step b: Retrieve the first version number of the first driver in a preset symbol table according to the driver loading notification.

[0055] Specifically, retrieve the first version number of the first driver in the preset symbol table according to the driver loading notification and the function naming rule.

[0056] Among them, the function naming rule is a prefix with a version number.

[0057] Step c: Perform version configuration on the first driver according to the first version number to complete the preliminary configuration of the first driver.

[0058] Step d: Perform first interface function configuration on the first driver to complete the configuration of the first driver.

[0059] Step e: Write the first driver into a preset routing table to obtain an initial routing table.

[0060] Step f: After obtaining the initial routing table, bind the first driver to the target virtual machine to complete the initialization of the target virtual machine, where the target virtual machine is created by an adapter through a preset virtualization technology.

[0061] In this embodiment, the adapter can be a host bus adapter or other adapters.

[0062] In this embodiment, the preset virtualization technology can be the SR-IOV technology or other virtualization technologies.

[0063] Among them, the SR-IOV technology is a hardware-accelerated virtualization technology that allows multiple virtual machines to access physical devices simultaneously, thereby improving the performance and reliability of virtual machines.

[0064] Specifically, the service data traffic is sent to the first driver through the initial routing table and the first interface function, so that the first driver performs format conversion on the service data traffic to obtain the converted service data traffic, and the converted service data traffic is sent to the target virtual machine.

[0065] S203: Initialize the virtual machine to be switched according to the pre-generated driver loading notification.

[0066] In this embodiment, the generation process of the driver loading notification includes steps g to j:

[0067] Step g: The adapter creates the virtual machine to be switched according to the preset virtualization technology.

[0068] Step h: The client sends a switching instruction and the corresponding switching data packet to the control platform.

[0069] In this embodiment, the client can be a user space management interface or other display interfaces.

[0070] Step i: The control platform registers the switching data packet as the second driver according to the switching instruction.

[0071] In this embodiment, the control platform can be a kernel state control platform or other control platforms.

[0072] Step j: The second driver sends a driver loading notification to the redirection layer.

[0073] In this embodiment, the redirection layer can be a dynamic request redirection layer or other redirection layers.

[0074] Specifically, step S203 specifically includes:

[0075] S2031: Retrieve the second version number of the second driver in the preset symbol table according to the driver loading notification.

[0076] S2032: Perform version configuration on the second driver according to the second version number to complete the preliminary configuration of the second driver.

[0077] S2033: Perform second interface function configuration on the second driver to complete the configuration of the second driver.

[0078] S2034: Write the second driver into the initial routing table to obtain a dual routing table.

[0079] In this embodiment, the dual-driver parallelism of the first driver and the second driver can also be achieved through the dual routing table.

[0080] In addition, by virtualizing the configuration space of the high-speed interconnect bus device, the first driver and the second driver respectively access independent memory-mapped input / output regions, achieving logical segmentation of hardware resources, and the first driver and the second driver can access the hardware resources simultaneously.

[0081] S2035: After obtaining the dual routing table, bind the second driver to the virtual machine to be switched, and complete the initialization of the virtual machine to be switched, where the virtual machine to be switched is created by the adapter through a preset virtualization technology.

[0082] S204: After the initialization of the virtual machine to be switched, send a switching prompt to the synchronization engine, so that the synchronization engine obtains the running data of the target virtual machine according to the switching prompt, copies the running data to the virtual machine to be switched, and generates a switching permission signal.

[0083] In this embodiment, the synchronization engine can be a state synchronization engine or other synchronization engines.

[0084] Specifically, the running data is copied to the virtual machine to be switched through the zero-copy transfer technology.

[0085] S205: Receive the switching permission signal sent by the synchronization engine.

[0086] S206: According to the switching permission signal, send the service data traffic to the virtual machine to be switched, so that the virtual machine to be switched processes the service data traffic.

[0087] Specifically, sending the service data traffic to the virtual machine to be switched in step S206 is specifically: according to the switching permission signal, send the service data traffic to the second driver through the dual routing table and the second interface function, so that the second driver performs format conversion on the service data traffic to obtain the converted service data traffic, and send the converted service data traffic to the virtual machine to be switched.

[0088] In addition, it is also necessary to control the queue load status of the virtual machine to be switched.

[0089] In addition, a secure offloading protection can also be set. The secure offloading protection is used to provide a driver rollback mechanism, and automatically switches back to the first driver when the second driver is abnormal.

[0090] In addition, the above-mentioned target virtual machine and the virtual machine to be switched are simultaneously allocated independent memory-mapped input / output spaces and interrupt vectors to prevent hardware resource conflicts.

[0091] In summary, the virtual machine switching processing method provided in this embodiment receives the service data traffic transmitted by the network interface, sends the service data traffic to the initialized target virtual machine so that the target virtual machine processes the service data traffic, initializes the virtual machine to be switched according to the pre-generated driver loading notification, and after the virtual machine to be switched is initialized, sends a switching prompt to the synchronization engine so that the synchronization engine obtains the running data of the target virtual machine according to the switching prompt, copies the running data to the virtual machine to be switched, and generates a switching permission signal. It receives the switching permission signal sent by the synchronization engine and, according to the switching permission signal, sends the service data traffic to the virtual machine to be switched so that the virtual machine to be switched processes the service data traffic. There is no need to pause receiving and processing the service data traffic to manually configure and switch the virtual machine to be switched, and the corresponding virtual machine can be automatically switched, ensuring the continuity of service traffic processing.

[0092] In addition, the virtual machine switching processing method provided in this embodiment realizes business unawareness during the driver upgrade process through the cooperation of hardware virtualization and the kernel state, ensuring the high availability of the key storage system.

[0093] In addition, the loose coupling design of each module in the virtual machine switching processing method provided in this embodiment supports flexible expansion and can adapt to various host bus adapter device types.

[0094] In addition, the virtual machine switching processing method provided in this embodiment sets up a secure uninstall protection, which is used to provide a driver rollback mechanism. When the second driver is abnormal, it automatically switches back to the first driver, increasing the reliability of virtual machine switching.

[0104] S305: Receive the switching permission signal sent by the synchronization engine.

[0105] S306: According to the switching permission signal, send the service data traffic to the virtual machine to be switched, so that the virtual machine to be switched processes the service data traffic.

[0106] In this embodiment, the discussion on sending the service data traffic to the virtual machine to be switched has been described in detail in step S206, and will not be elaborated here.

[0107] S307: Receive the inventory processing request sent by the target virtual machine, where the inventory processing request is sent by the virtual machine to be switched to the target virtual machine, and the inventory processing request is generated after the virtual machine to be switched interrupts the service data traffic processing process after a preset time.

[0108] S308: According to the inventory processing request, send the inventory service data traffic to the target virtual machine, so that the target virtual machine processes the inventory service data traffic. The inventory service data traffic is obtained by storing the unprocessed service data traffic according to the temporary storage service data traffic notification, and the temporary storage service data traffic notification is sent by the synchronization engine.

[0109] In this embodiment, the sending of the temporary storage service data traffic notification and the generation of the inventory service data traffic are performed after sending the switching prompt to the redirection layer in step S304.

[0110] S309: Receive the uninstallation notification sent by the user terminal, where the uninstallation notification is generated after the user terminal queries that the inventory service data traffic processing is completed.

[0111] S310: Uninstall the first interface function according to the uninstall notification, and generate an unbinding notification.

[0112] S311: Send an unbinding notification to the first driver so that the first driver unbinds from the target virtual machine according to the unbinding notification, generates a binding unbinding prompt, sends the binding unbinding prompt to the user end so that the user end uninstalls the first driver according to the binding unbinding prompt, obtains the first running status data of the target virtual machine, obtains the second running status data of the virtual machine to be switched, generates a virtual machine switching report according to the first running status data and the second running status data, and outputs the virtual machine switching report.

[0113] In this embodiment, the virtual machine switching report at least includes switching time consumption, performance fluctuation analysis and abnormal event log.

[0114] In summary, the virtual machine switching processing method provided in the present embodiment receives an inventory processing request sent by the target virtual machine, sends the inventory business data traffic to the target virtual machine according to the inventory processing request, so that the target virtual machine processes the inventory business data traffic, receives an uninstallation notification sent by the user end, uninstalls the first interface function according to the uninstallation notification, generates an unbinding notification, sends the unbinding notification to the first driver, so that the first driver unbinds from the target virtual machine according to the unbinding notification, generates a binding unbinding prompt, sends the binding unbinding prompt to the user end, so that the user end uninstalls the first driver according to the binding unbinding prompt, generates a virtual machine switching report using the first operating status data of the target virtual machine and the second operating status data of the virtual machine to be switched, and outputs the virtual machine switching report, so that the user can more intuitively understand the operation of the target virtual machine and the virtual machine to be switched, thereby improving the user experience.

[0115] In addition, the virtual machine switching processing method provided in this embodiment saves the operating resources of the device by binding the first driver to the target virtual machine and uninstalling the first driver.

[0116] Figure 4 A schematic diagram of a virtual machine switching process provided in an embodiment of the present application Figure 3 ,like Figure 4 As shown, the embodiment of the present application provides another virtual machine switching processing method, and the method is described in detail as follows:

[0117] S401: After the virtual machine to be switched is initialized, a switching prompt sent by the redirection layer is received. The initialization of the virtual machine to be switched is completed by the redirection layer according to the pre-generated driver loading notification.

[0118] S402: Acquire the operation data of the initialized target virtual machine according to the switching prompt.

[0119] In this embodiment, the running data at least includes register mirror data, system memory, and interrupt migration information; the register mirror data includes one or more pieces of mirror data; the system memory data is a corresponding data list, and the data list includes one or more pieces of table data; the interrupt migration information at least includes interrupt status data, and the interrupt status data contains an interrupt vector. Accordingly, step S502 is specifically: obtaining the register mirror data, system memory data, and interrupt migration information of the target virtual machine according to the switching prompt.

[0120] S403: Copy the running data to the virtual machine to be switched, and generate a switching permission signal.

[0121] Specifically, step S403 specifically includes:

[0122] S4031: Copy one or more pieces of mirror data in the register mirror data to the virtual machine to be switched.

[0123] In this embodiment, the mirror data is control register data, queue pointer, hardware address, and other mirror data.

[0124] S4032: Copy one or more pieces of table data in the data list corresponding to the system memory data to the virtual machine to be switched.

[0125] In this embodiment, the data list can be a Scatter-Gather list or other lists.

[0126] Among them, the Scatter-Gather list is a data structure used to describe a data buffer. It is mainly used in the memory address space to identify the data of the source buffer or the target buffer.

[0127] S4033: Disable the interrupt enable of the virtual machine to be switched, and copy the interrupt status data in the interrupt migration information to the virtual machine to be switched, where the interrupt status data is used to indicate redirecting the interrupt vector to the virtual machine to be switched.

[0129] In this embodiment, the interrupt vector can be an MSI-X interrupt vector table or other vectors.

[0130] Among them, the MSI-X interrupt vector is the unique identifier for the high-speed interconnect bus device to trigger a specific interrupt event through the MSI-X interrupt mechanism. Each vector corresponds to an independent interrupt service program entry address, which is used to process different hardware events.

[0131] In addition, the interrupt status data is also used to submit the interrupt vector to the second driver for processing.

[0132] S404: Send the handover permission signal to the redirection layer so that the redirection layer sends the service data traffic to the virtual machine to be handed over according to the handover permission signal, so that the virtual machine to be handed over processes the service data traffic, where the service data traffic is obtained by the redirection layer through the network interface, and before the service data traffic is sent to the virtual machine to be handed over, the service data traffic is processed by the target virtual machine.

[0133] In summary, the virtual machine handover processing method provided in this embodiment receives a handover prompt sent by the redirection layer after the virtual machine to be handed over is initialized; obtains the running data of the initialized target virtual machine according to the handover prompt; copies the running data to the virtual machine to be handed over and generates a handover permission signal; sends the handover permission signal to the redirection layer so that the redirection layer sends the service data traffic to the virtual machine to be handed over according to the handover permission signal, so that the virtual machine to be handed over processes the service data traffic, and before the service data traffic is sent to the virtual machine to be handed over, the service data traffic is processed by the target virtual machine. There is no need to pause receiving and processing the service data traffic to manually configure and switch the virtual machine to be handed over, and the corresponding virtual machine can be automatically switched, ensuring the continuity of service traffic processing.

[0134] In addition, the virtual machine handover processing method provided in this embodiment can improve the subsequent virtual machine handover efficiency by obtaining the running data of the target virtual machine and copying the running data to the virtual machine to be handed over.

[0135] Figure 5 It is a schematic flow of the virtual machine handover processing method provided in the embodiment of the present application Figure 4 , such as Figure 5 shown, the embodiment of the present application provides another virtual machine handover processing method, and the method is described in detail as follows:

[0136] S501: The redirection layer receives the service data traffic transmitted by the network interface and sends the service data traffic to the initialized target virtual machine.

[0137] S502: The target virtual machine processes the service data traffic.

[0138] S503: The redirection layer initializes the virtual machine to be handed over according to the pre-generated driver loading notification, and after the virtual machine to be handed over is initialized, sends a handover prompt to the synchronization engine.

[0139] S504: The synchronization engine obtains the running data of the target virtual machine, copies the running data to the virtual machine to be handed over, generates a handover permission signal, and sends the handover permission signal to the redirection layer.

[0140] S505: Redirection layer, which sends the service data traffic to the virtual machine to be switched according to the handover permission signal.

[0141] S506: The virtual machine to be switched processes the service data traffic.

[0142] In summary, the virtual machine handover processing method provided in this embodiment receives the service data traffic transmitted by the network interface through the redirection layer and sends the service data traffic to the initialized target virtual machine; the target virtual machine processes the service data traffic; the redirection layer completes the initialization of the virtual machine to be switched according to the pre-generated driver loading notification, and after the initialization of the virtual machine to be switched, sends a handover prompt to the synchronization engine; the synchronization engine obtains the running data of the target virtual machine, copies the running data to the virtual machine to be switched, generates a handover permission signal, and sends the handover permission signal to the redirection layer; the redirection layer sends the service data traffic to the virtual machine to be switched according to the handover permission signal; the virtual machine to be switched processes the service data traffic, without the need to pause receiving and processing the service data traffic to manually configure and switch the virtual machine to be switched, and can automatically switch the corresponding virtual machine, thus ensuring the continuity of service traffic processing.

Of course, it can also be implemented by hardware, but in many cases, the former is a better implementation method.

[0144] It should be noted that the redirection layer, the first driver, and the second driver can be divided into the data plane; the high-speed interconnect bus device virtualization agent, the target virtual machine, and the virtual machine to be switched can be divided into the hardware abstraction layer.
