[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] like Figure 1 As shown, the operation and maintenance and configuration changes of virtual machines in the virtualization architecture in the related art are usually completed by manually sending network control instructions (operation and maintenance data or configuration instructions) on the cloud server (Elastic Compute Service, ECS) control end to control the virtual machine simulator (Quick Emulator, QEMU) on the host machine; however, in order to reduce bandwidth and storage costs, QEMU will downgrade the accuracy of the collected operation and maintenance data (such as processor stealing time, etc.) and send it to the ECS console, which will cause the operation and maintenance personnel to be unable to obtain high-precision operation and maintenance data; in addition, since the operation and maintenance and configuration changes of virtual machines are based on the network, when the network fluctuates, it is impossible to perform real-time configuration for tasks with drastic performance fluctuations.

[0025] In order to solve the above technical problems, as an optional implementation method, Figure 3 As shown, the embodiment of the present application provides a virtual machine management method, which is applied to a virtual machine and includes the following steps:

[0026] S202: Receive a communication message for managing the virtual machine, sent by an application running on the virtual machine.

[0027] Specifically, in the embodiments of the present application, Figure 3As shown, the application running in the virtual machine can be an application that exclusively occupies the virtual machine in the user space, such as a cloud desktop application, etc., or it can be an application that runs in multiple applications in the virtual machine and is used to manage the configuration of the virtual machine. The communication message used to manage the virtual machine includes a message header and payload data; the above-mentioned message header may include the type of message, such as the message type that requires increasing resources or the message type that requires reducing resources, and the payload data may be the number of resources increased or decreased. The type of the above-mentioned message can also be an operation and maintenance data type, such as the number of read and write operations per second (Input / Output Operations Per Second, IOPS) of the process. The virtual machine transmits the above-mentioned communication message to the driver of the kernel space of the virtual machine through the input / output channel management interface (input / output control, ioctl).

[0028] S304: Write the communication message into a virtual queue, so that the virtual machine simulator corresponding to the virtual machine obtains the communication message from the virtual queue; the virtual queue is a data link connecting the driver of the virtual machine and the driver of the virtual machine simulator.

[0029] Specifically, in an embodiment of the present application, the virtual queue (Vring) for transmitting communication messages is a data link connecting the virtual machine driver and the virtual machine emulator driver. This virtual queue (Vring) can be a message queue in a paravirtualized device (Virtual Input / Output Device). After the virtual machine driver writes the communication message to the virtual queue, the virtual machine emulator (QEMU) can obtain the communication message from the virtual queue (Vring), thereby managing the virtual configuration and obtaining high-precision operation and maintenance data.

[0030] In an embodiment of the present application, a method is adopted for receiving a communication message for managing the virtual machine sent by an application running on the virtual machine; the communication message is written into a virtual queue, and the virtual machine simulator corresponding to the virtual machine obtains the communication message from the virtual queue; the virtual queue is a method for connecting the data link of the driver of the virtual machine and the driver of the virtual machine simulator; the present application does not need to downgrade the accuracy of the operation and maintenance data collected by the virtual machine simulator QEMU and can send it to the operation and maintenance personnel through the virtual queue. The operation and maintenance personnel of the virtual machine can obtain high-precision operation and maintenance data, and based on the method of carrying the above-mentioned communication messages through the virtual queue, the resources of the virtual machine can also be updated in real time to meet the task resource requirements with severe performance fluctuations in the virtual machine, and significantly improve the operation and maintenance and configuration efficiency of the virtual machine.

[0031] In one or more embodiments, the communication message carries a message type and payload data, and writing the communication message into the virtual queue includes:

[0032] A communication message body corresponding to the message type and payload data in the communication message is created, and the message body is written into the virtual queue.

[0033] Specifically, in the embodiments of the present application, Figure 3 As shown, the virtual machine driver combines the message type (message header) and payload data (Payload) of the received communication message into a message body, where the message type corresponds to the first sequence data (Sg[0]) of the message body, and the payload data is the second sequence data (Sg[1]) of the message body. The virtual machine driver then writes the message body into the virtual queue Vring.

[0034] In one or more embodiments, after receiving a message sent by an application running on the virtual machine for managing the virtual machine, the method further includes:

[0035] Determine that the communication message is received, call the driver of the virtual machine to apply for memory space from the memory of the virtual machine; and write address information corresponding to the memory space into the effective load data.

[0036] Specifically, in an embodiment of the present application, after the virtual machine receives a communication message sent by an application, the driver of the virtual machine is called to apply for memory space from the memory of the virtual machine. The memory space is a currently unused storage space. After that, the address information corresponding to the memory space applied for by the virtual machine is written into the payload data. The above address information can be passed to the virtual machine simulator QEMU through the virtual queue Vring. It should be noted that the memory space can store the operation and maintenance information (such as IOPS data) sent by the application of the virtual machine, and can also store the operation and maintenance information (such as processor stealing time) generated by the virtual machine simulator. By using this memory space, high-precision operation and maintenance data can be loaded without downgrading the accuracy of the operation and maintenance data, for example, there is no need to save bandwidth and downgrade the processor stealing time from milliseconds to seconds.

[0037] In one or more embodiments, the message type includes a first message type for indicating obtaining operation and maintenance data from a virtual machine simulator, and the method further includes:

[0038] Based on the address information corresponding to the memory space, the operation and maintenance data fed back by the virtual machine simulator for the first message type is read from the memory space.

[0039] Specifically, in an embodiment of the present application, the above-mentioned first message type can be, for example, the processor stealing time or other operation and maintenance data fed back by the virtual machine simulator for the current virtual machine. After the virtual machine simulator QEMU obtains the address information corresponding to the above-mentioned memory space from the virtual machine queue Vring, for example, the processor stealing time or other operation and maintenance data fed back by the virtual machine simulator for the current virtual machine can be written into the above-mentioned memory space, and the virtual machine can read the above-mentioned operation and maintenance data from the memory space.

[0040] In one or more embodiments, the message type includes a second message type for instructing to send operation and maintenance data to the virtual machine simulator, and the method further includes:

[0041] Based on the address information corresponding to the memory space, operation and maintenance data corresponding to the second message type is written into the memory space, so that the virtual machine simulator reads the operation and maintenance data corresponding to the second message type from the memory space.

[0042] Specifically, in an embodiment of the present application, the second message type may be, for example, the number of read and write times per second of a process in the virtual machine, or other operational data reported by the current virtual machine. Based on the address information corresponding to the memory space, the virtual machine may, for example, write the number of read and write times per second of a process, or other operational data reported by the current virtual machine, to the memory space. The virtual machine simulator may then read the operational data from the memory space based on the address information corresponding to the memory space.

[0043] In one or more embodiments, the message type includes a resource configuration type, the payload data includes resource configuration information, and creating a communication message body corresponding to the message type and payload data in the communication message includes:

[0044] Using the resource configuration type as the first sequence data and the resource configuration information as the second sequence data;

[0045] The communication message body is created based on the first sequence data and the second sequence data.

[0046] Specifically, in the embodiment of the present application, the resource configuration type may be, for example, a processor configuration type or a storage space configuration type, or a network configuration type; the resource configuration information may be, for example, an increase or decrease in the number of processors, or an increase or decrease in the size of the memory space; Figure 3As shown, the virtual machine driver uses the received resource configuration type as the first sequence data (Sg[0]) and the resource configuration information as the second sequence data (Sg[1]); and creates the communication message body based on the first sequence data Sg[0] and the second sequence data Sg[1]. When the virtual machine simulator receives the communication message body, it changes the resource configuration of the virtual machine in real time and efficiently based on the resource configuration type and resource configuration information in the message body.

[0047] In one or more embodiments, the resource configuration type includes a computing power configuration type; when a current computing power parameter of the virtual machine meets a preset overload condition, the computing power configuration type is an increase computing power type, and the resource configuration information includes a computing power increase parameter;

[0048] When the current computing power parameter satisfies a preset computing power sufficient condition, the computing power configuration type is a computing power reduction type, and the resource configuration information includes a computing power reduction parameter.

[0049] Specifically, in an embodiment of the present application, for example, if the computing power required by the application running on the current virtual machine is large and the current computing power of the virtual machine is overloaded, the virtual machine needs to transmit the type of computing power increase and the computing power increase parameters to the virtual machine simulator via the above-mentioned communication message body. The virtual machine simulator increases the computing power resources of the virtual machine based on the type of computing power increase and the computing power increase parameters. For example, if the current processor utilization of the virtual machine is greater than the preset utilization, the above-mentioned computing power configuration type is the message type of increasing the processor, and the resource configuration information includes parameters such as the number of processors to be increased.

[0050] For example, if the application running on the current virtual machine is running smoothly and the virtual machine's current computing power is sufficient, the virtual machine needs to transmit the computing power reduction type and computing power reduction parameters to the virtual machine simulator via the above communication message body. The virtual machine simulator reduces the virtual machine's computing power resources based on the computing power reduction type and computing power reduction parameters. For example, if the virtual machine's current processor utilization is less than or equal to the preset utilization rate, the computing power configuration type is the processor reduction message type, and the resource configuration information includes parameters such as the number of processors to be reduced.

[0051] As an optional implementation method, Figure 4 As shown, an embodiment of the present application provides a virtual machine management method, which is applied to a virtual machine simulator, where a virtual machine is running on a host machine where the virtual machine simulator is located, including the following steps:

[0052] S402, obtaining a communication message for managing the virtual machine from a virtual queue; the virtual queue is a data link connecting a driver of the virtual machine and a driver of the host machine;

[0053] S404: Execute a processing strategy corresponding to the communication message.

[0054] Specifically, in the embodiment of the present application, the virtual queue Vring for transmitting communication messages is a data link connecting the driver of the virtual machine and the driver of the virtual machine simulator. The virtual queue Vring can be a message queue in a paravirtualized device (Virtual I / O Device). Figure 3 As shown, after the virtual machine driver writes the communication message used to manage the virtual machine into the virtual queue, the virtual machine simulator QEMU obtains the above communication message from the virtual queue Vring to achieve control over the virtual configuration and obtain high-precision operation and maintenance data.

[0055] In an embodiment of the present application, a communication message for managing the virtual machine is obtained from a virtual queue; the virtual queue is a data link connecting the driver of the virtual machine and the driver of the virtual machine simulator; a method for executing a processing strategy corresponding to the communication message is adopted; the present application does not need to downgrade the accuracy of the operation and maintenance data collected by the virtual machine simulator QEMU and can send it to the operation and maintenance personnel through the virtual queue. The operation and maintenance personnel of the virtual machine can obtain high-precision operation and maintenance data, and based on the method of carrying the above-mentioned communication messages through the virtual queue, the resources of the virtual machine can also be updated in real time to meet the task resource requirements with severe performance fluctuations in the virtual machine, and significantly improve the operation and maintenance and configuration efficiency of the virtual machine.

[0056] In one or more embodiments, executing the processing strategy corresponding to the communication message includes:

[0057] Determining that the message type carried by the communication message is a first message type, and generating operation and maintenance data corresponding to the first message type; the first message type is used to indicate obtaining operation and maintenance data from a virtual machine simulator;

[0058] Acquire address information corresponding to the memory space from the communication message, and write operation and maintenance data corresponding to the first message type into the memory space; the memory space is the storage space applied for by the driver of the virtual machine from the memory of the virtual machine.

[0059] Specifically, in an embodiment of the present application, the above-mentioned first message type can be, for example, the processor stealing time or other operation and maintenance data fed back by the virtual machine simulator QEMU for the current virtual machine. When the virtual machine simulator QEMU obtains the above-mentioned message type as the type of operation and maintenance message obtained, and the address information corresponding to the memory space from the virtual machine queue Vring, for example, the processor stealing time or other operation and maintenance data fed back by the virtual machine simulator for the current virtual machine can be written into the memory space corresponding to the above-mentioned address information, and the virtual machine can read the above-mentioned operation and maintenance data from the memory space.

[0060] In one or more embodiments, executing the processing strategy corresponding to the communication message includes:

[0061] Determining that the message type carried by the communication message is a second message type, and obtaining address information corresponding to the memory space from the communication message; the second message type is used to indicate sending operation and maintenance data to the virtual machine simulator, and the memory space is a storage space applied for by the driver of the virtual machine from the memory of the virtual machine;

[0062] The operation and maintenance data corresponding to the second message type written by the virtual machine is read from the memory space based on the address information.

[0063] Specifically, in an embodiment of the present application, the second message type may be, for example, the number of read and write times per second of a process in a virtual machine or other operation and maintenance data fed back by the current virtual machine. The virtual machine may, based on the address information corresponding to the memory space, write the number of read and write times per second of a process or other operation and maintenance data fed back by the current virtual machine into the memory space. When the message type of the communication message received by the virtual machine simulator is the type of operation and maintenance data fed back by the current virtual machine, the address information corresponding to the memory space is obtained from the communication message. The virtual machine simulator may then read from the memory space, based on the address information corresponding to the memory space, the operation and maintenance data corresponding to the second message type written by the virtual machine.

[0064] In one or more embodiments, executing the processing strategy corresponding to the communication message further includes:

[0065] Determining a resource configuration type corresponding to the communication message;

[0066] The configuration of the virtual machine is updated according to the resource configuration type and the resource configuration information carried in the communication message.

[0067] In an embodiment of the present application, for example, if the application running on the current virtual machine requires a large number of resources, the virtual machine will increase the resource type and resource increase parameters through the above-mentioned communication message body to the virtual machine simulator, and the virtual machine simulator will increase the resources required by the virtual machine according to the resource configuration type and resource increase parameters.

[0068] For example, if the application running on the current virtual machine runs smoothly and the current resource utilization of the virtual machine is low, the virtual machine will reduce the resource type and resource reduction parameters through the above communication message body to the virtual machine simulator. The virtual machine simulator will reduce the resources required by the virtual machine according to the resource configuration type and resource reduction parameters.

[0069] In one or more embodiments, the resource configuration type includes a computing power configuration type, the resource configuration information includes a computing power increase parameter or a computing power decrease parameter, and updating the configuration of the virtual machine according to the resource configuration type and the configuration information of the computing power resource carried by the communication message includes:

[0070] Determine that the resource configuration type of the communication message is a computing power configuration type, and increase the computing power resources of the virtual machine according to the computing power increase parameter; or, reduce the computing power resources of the virtual machine according to the computing power reduction parameter.

[0071] Specifically, in an embodiment of the present application, for example, if the computing power required by the application running on the current virtual machine is large and the current computing power of the virtual machine is overloaded, the virtual machine needs to transmit the type of computing power increase and the computing power increase parameters to the virtual machine simulator via the above-mentioned communication message body. The virtual machine simulator increases the computing power resources of the virtual machine based on the type of computing power increase and the computing power increase parameters. For example, if the current processor utilization of the virtual machine is greater than the preset utilization, the above-mentioned computing power configuration type is the message type of increasing the processor, and the resource configuration information includes parameters such as the number of processors to be increased.

[0072] For example, if the application running on the current virtual machine is running smoothly and the virtual machine's current computing power is sufficient, the virtual machine needs to transmit the computing power reduction type and computing power reduction parameters to the virtual machine simulator via the above communication message body. The virtual machine simulator reduces the virtual machine's computing power resources based on the computing power reduction type and computing power reduction parameters. If the current processor utilization of the virtual machine is less than or equal to the preset utilization, the computing power configuration type is the message type for reducing processors, and the resource configuration information includes parameters such as the number of processors to be reduced.

[0073] Based on the above embodiment, in an application embodiment, if Figure 3As shown in Figure 1, the application architecture of the virtual machine management method consists of three parts: (1) the application running in the user space of the guest virtual machine (Guest VM); (2) the driver running in the kernel space of the Guest VM; and (3) the virtual machine emulator QEMU running on the host. The Guest VM communicates with the corresponding virtualization driver based on the peripheral component interconnect (PCI) bus, namely the Virtio-pci device.

[0074] The user space application passes a communication message (ioctl cmd message) to the kernel space through the input / output channel control interface (ioctl) ioctl interface. The communication message consists of two parts:

[0075] 1. Message header: fixed 8 bytes, used to mark the type of this message;

[0076] 2. Payload data: of variable length, used to transmit the actual payload information of the message, such as operation and maintenance data or configuration parameters.

[0077] The communication message is passed to the virtual machine controller QEMU on the host through the virtual queue Vring on the kernel space side. The specific process includes: forming the communication message into a message body Sgs (sg[0] and sg[1]), writing the message body Sgs into Vring, adding a buffer to Vring through the vq_add_buff function, and then notifying the virtual machine emulator QEMU on the host to process the message through the Kick function.

[0078] The kernel-space driver transmits messages synchronously. After sending a message, the kernel-space driver blocks subsequent messages until it receives a return value from the virtual machine emulator (QEMU). Only then will it write a second message. When a message arrives at QEMU, QEMU extracts the message and, depending on the message type contained in the header, invokes different processing logic. Finally, it writes the return value to the Vring.

[0079] 2. Operation and maintenance solutions based on communication architecture include:

[0080] 1. In the guest virtual machine, the driver applies for a piece of memory space with continuous addresses;

[0081] 2. The guest virtual machine writes the address and storage capacity of the memory space into the payload data of the communication message, and further passes it to the virtual machine emulator QEMU through Vring.

[0082] Reading and writing operation and maintenance information on the guest virtual machine side: GuestVM writes the information required by QEMU (such as the IOPS of the process in the guest virtual machine) to the agreed location of the memory space, and can also read the operation and maintenance information written by QEMU from the agreed location.

[0083] QEMU reads and writes operation and maintenance information: QEMU writes the operation and maintenance information required by the guest virtual machine (such as processor steal time) to the agreed memory location, and can also read the operation and maintenance information written by the guest virtual machine from the agreed location.

[0084] Through the above technical means, this application can enable the guest virtual machine and the host machine to directly read and write original high-precision and highly effective operation and maintenance data, and realize the exchange of operation and maintenance data through memory mapping, thereby reducing message latency.

[0085] 3. Configuration solutions based on communication architecture include:

[0086] The guest VM informs the virtual machine simulator of its required resources through the above communication framework. The virtual machine simulator dynamically allocates resources to the guest VM according to the policy. The following example uses the processor as an example:

[0087] When an application in a guest VM is running low on computing power, it requests processing resources by sending a message to QEMU, requesting an increase in the number of processors. The message type is stored in the header, and the number of processors requested is stored in the payload. Upon receiving the message, QEMU increases the number of processors in the guest VM based on the number of processors in the payload.

[0088] When applications in a guest VM are running smoothly, they can request processing resources by sending a "reduce processor count" message to QEMU. The message type is stored in the header, and the number of processors requested is stored in the payload. Upon receiving the message, QEMU reduces the number of processors in the guest VM based on the number of processors in the payload.

[0089] Through the above technical means, the present application can realize the real-time resource configuration requirements of the guest virtual machine, and can perform real-time configuration for tasks with severe performance fluctuations of the guest virtual machine.
