Description

[0001] Virtual Machine Management Technology Field

[0002]

[0001] The present disclosure relates to the field of cloud computing technology, and more particularly to virtual machine management.

[0003]

[0002] In existing virtualization architectures, virtual machine operation and maintenance, as well as configuration changes, are typically accomplished manually by manually sending network control commands from the Elastic Compute Service (ECS) control terminal to the host machine's Quick Emulator (QEMU). However, to reduce bandwidth and storage costs, QEMU downgrades the accuracy of collected operation and maintenance data (such as processor stealing time) before sending it to the ECS console. This prevents operation and maintenance personnel from obtaining high-precision operation and maintenance data. Furthermore, because virtual machine operation and maintenance, as well as configuration changes, are network-based, real-time configuration cannot be performed for tasks with drastic performance fluctuations when the network experiences network fluctuations. Summary of the Invention

[0023] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence.

[0024]

[0024] As shown in Figure 1, the operation and maintenance of virtual machines in a virtualization architecture in the related art and configuration changes are usually completed by manually sending network control instructions (operation and maintenance data or configuration instructions) from the cloud server (Elastic Compute Service, ECS) control terminal 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.) before sending it to the ECS console. This will cause the operation and maintenance personnel to be unable to obtain high-precision operation and maintenance data. In addition, because the operation and maintenance and configuration changes of virtual machines are implemented based on the network, when the network fluctuates, it is impossible to perform real-time configuration for tasks with severe performance fluctuations.

[0025]

[0025] In order to solve the above technical problems, as an optional implementation method, as shown in FIG2, the embodiment of the present disclosure provides a virtual machine management method, which is applied to a virtual machine and includes the following steps.

[0026]

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

[0027]

[0027] Specifically, in the embodiment of the present disclosure, as shown in FIG3 , the application running in the virtual machine can be a user space

[0028] (user space) An application that exclusively occupies the virtual machine, such as a cloud desktop application, or an application that runs in multiple applications in the virtual machine and is used to manage the virtual machine configuration. The communication message used to manage the virtual machine includes a message header

[0029] The message header and payload data can include the message type, such as a message type indicating a resource increase or decrease, and the payload data can include the amount of resources to be increased or decreased. The message type can also be an operation and maintenance data type, such as the number of read and write operations per second (IOPS) of a process. The virtual machine transmits the communication message to the driver in the kernel space of the virtual machine through the input / output control interface (ioctl).

[0030]

[0028] S204, writing 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.

[0031] Specifically, in the disclosed embodiments, a virtual queue (Vring) for transmitting communication messages is a data link connecting the virtual machine driver and the virtual machine emulator driver. The virtual queue (Vring) may 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 retrieve the communication message from the virtual queue (Vring), thereby managing virtual configurations and obtaining high-precision operation and maintenance data.

[0032]

[0030] In an embodiment of the present disclosure, a communication message for managing the virtual machine sent by an application running on the virtual machine is received; 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 a data link connecting the driver of the virtual machine and the driver of the virtual machine simulator; the present disclosure does not need to degrade 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 resource requirements of tasks with severe performance fluctuations in the virtual machine, thereby significantly improving the operation and maintenance and configuration efficiency of the virtual machine.

[0033]

[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: creating a communication message body corresponding to the message type and payload data in the communication message, and writing the message body into the virtual queue.

[0034] Specifically, in the embodiment of the present disclosure, as shown in FIG3 , 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 serves as the second sequence data (Sg[1]) of the message body. The virtual machine driver then writes the message body into the virtual queue Vring.

[0035]

[0033] In one or more embodiments, after receiving the communication message sent by the application running on the virtual machine for managing the virtual machine, it also includes: determining that the communication message is received, calling the driver of the virtual machine to apply for memory space from the memory of the virtual machine; and writing the address information corresponding to the memory space into the payload data.

[0036]

[0034] Specifically, in the disclosed embodiment, after a virtual machine receives a communication message sent by an application, it calls the virtual machine's driver to request memory space from the virtual machine's memory. This memory space is currently unused storage space. The virtual machine then writes the address information corresponding to the memory space requested by the virtual machine into the payload data. This address information can be passed to the virtual machine emulator QEMU via a virtual queue Vring. It should be noted that this memory space can store operation and maintenance information (such as IOPS data) sent by the virtual machine's application, as well as operation and maintenance information (such as processor steal time) generated by the virtual machine emulator. By utilizing 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 downgrade the processor steal time from milliseconds to seconds to save bandwidth.

[0037]

[0035] 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: based on the address information corresponding to the memory space, reading the operation and maintenance data fed back by the virtual machine simulator for the first message type from the memory space.

[0038]

[0036] Specifically, in the embodiment of the present disclosure, 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.

[0039]

[0037] In one or more embodiments, the message type includes a second message type for indicating that operation and maintenance data is to be sent to the virtual machine simulator, and the method further includes: based on the address information corresponding to the memory space, writing the operation and maintenance data corresponding to the second message type to 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.

[0038] Specifically, in the embodiments of the present disclosure, 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 operation and maintenance data currently fed back by the 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 operation and maintenance data currently fed back by the virtual machine to the memory space. The virtual machine simulator may then read the operation and maintenance data from the memory space based on the address information corresponding to the memory space.

[0040]

[0039] In one or more embodiments, the message type includes a resource configuration type, the payload data includes resource configuration information, and the creation of a communication message body corresponding to the message type and payload data in the communication message includes: using the resource configuration type as the first sequence data and the resource configuration information as the second sequence data; and creating the communication message body based on the first sequence data and the second sequence data.

[0041] Specifically, in the embodiments of the present disclosure, the resource configuration type may be, for example, a processor configuration type, 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 memory space; as shown in FIG3 , the virtual machine driver uses the received resource configuration type as first sequence data (Sg[0]) and the resource configuration information as 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]. After receiving the communication message body, the virtual machine simulator efficiently and in real time changes the resource configuration of the virtual machine based on the resource configuration type and resource configuration information in the message body.

[0042]

[0041] In one or more embodiments, the resource configuration type includes a computing power configuration type; when the current computing power parameter of the virtual machine meets the 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; when the current computing power parameter meets the preset computing power sufficient condition, the computing power configuration type is a decrease computing power type, and the resource configuration information includes a computing power decrease parameter.

[0043] Specifically, in the embodiments of the present disclosure, for example, if the computing power required by an application running on the current virtual machine is high and the current computing power of the virtual machine is overloaded, the virtual machine needs to transmit the computing power increase type and computing power increase parameters to the virtual machine simulator via the communication message body. The virtual machine simulator increases the computing power resources of the virtual machine based on the computing power increase type and computing power increase parameters. For example, if the current processor utilization of the virtual machine is greater than a preset utilization rate, the computing power configuration type is a message type for increasing processors, and the resource configuration information includes parameters such as the number of processors to be increased.

[0044] For example, if an application running on the current virtual machine is running smoothly and the current computing power of the virtual machine 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 communication message body. The virtual machine simulator reduces the computing power resources of the virtual machine based on the computing power reduction type and computing power reduction parameters. For example, if the current processor utilization of the virtual machine is less than or equal to the preset utilization, the computing power configuration type is a message type for reducing processors, and the resource configuration information includes parameters such as the number of processors to be reduced.

[0045]

[0044] As an optional implementation, as shown in FIG4, an embodiment of the present disclosure 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, and includes the following steps.

[0046]

[0045] S402, obtaining a communication message for managing the virtual machine from a virtual queue; the virtual queue is a data link connecting the driver of the virtual machine and the driver of the host machine.

[0047]

[0046] S404, executing the processing strategy corresponding to the communication message.

[0048] Specifically, in the disclosed embodiment, a virtual queue (Vring) for transmitting communication messages is a data link connecting the virtual machine driver and the virtual machine simulator driver. This virtual queue (Vring) may be a message queue for a paravirtualized device (Virtual I / O Device) t. As shown in FIG3 , after the virtual machine driver writes a communication message for managing the virtual machine into the virtual queue, the virtual machine simulator QEMU retrieves the communication message from the virtual queue (Vring), thereby enabling management and control of virtual configurations and obtaining high-precision operation and maintenance data.

[0049]

[0048] In an embodiment of the present disclosure, 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; the present disclosure 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 resource requirements of tasks with severe performance fluctuations in the virtual machine, and significantly improve the operation and maintenance and configuration efficiency of the virtual machine.

[0050]

[0049] In one or more embodiments, the execution of the processing strategy corresponding to the communication message includes: 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 that the operation and maintenance data is obtained from the virtual machine simulator; obtaining address information corresponding to the memory space from the communication message, and writing the 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.

[0051]

[0050] Specifically, in an embodiment of the present disclosure, the first message type may be, for example, processor stealing time or other operation and maintenance data fed back by the virtual machine simulator QEMU for the current virtual machine. After the virtual machine simulator QEMU obtains the message type indicating that the operation and maintenance message is obtained, as well as address information corresponding to the memory space, from the virtual machine queue Vring, the processor stealing time or other operation and maintenance data fed back by the virtual machine simulator for the current virtual machine may be written to the memory space corresponding to the address information, and the virtual machine may then read the operation and maintenance data from the memory space.

[0051] In one or more embodiments, executing the processing strategy corresponding to the communication message includes: determining that the message type carried by the communication message is a second message type, obtaining address information corresponding to the memory space from the communication message; the second message type is used to indicate that operation and maintenance data is to be sent to the virtual machine simulator, the memory space being storage space requested by the virtual machine driver from the memory of the virtual machine; and reading the operation and maintenance data corresponding to the second message type written by the virtual machine from the memory space based on the address information.

[0052]

[0052] Specifically, in the embodiments of the present disclosure, 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 operation and maintenance 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 the process, or other operation and maintenance data reported 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 the operation and maintenance data reported by the current virtual machine, the virtual machine simulator obtains the address information corresponding to the memory space from the communication message. The virtual machine simulator can then read the operation and maintenance data corresponding to the second message type written by the virtual machine from the memory space based on the address information corresponding to the memory space.

[0053]

[0053] In one or more embodiments, executing the processing strategy corresponding to the communication message further includes: determining the resource configuration type corresponding to the communication message; and updating the configuration of the virtual machine according to the resource configuration type and the resource configuration information carried by the communication message.

[0054]

[0054] In the embodiment of the present disclosure, for example, if the application running on the current virtual machine requires a large number of resources, the virtual machine will transmit the increased resource type and resource increase parameters to the virtual machine simulator through the above-mentioned communication message body, and the virtual machine simulator will increase the resources required by the virtual machine according to the resource configuration type and resource increase parameters.

[0055]

[0055] For another 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 transmit the resource reduction type and resource reduction parameters to the virtual machine simulator through the above-mentioned communication message body, and the virtual machine simulator will reduce the resources required by the virtual machine according to the resource configuration type and resource reduction parameters.

[0056]

[0056] 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 reduction parameter, and updating the configuration of the virtual machine according to the resource configuration type and the configuration information of the computing power resources carried by the communication message includes: determining that the resource configuration type of the communication message is a computing power configuration type, and increasing the computing power resources of the virtual machine according to the computing power increase parameter; or, reducing the computing power resources of the virtual machine according to the computing power reduction parameter.

[0057]

[0057] Specifically, in the embodiments of the present disclosure, for example, if the computing power required by an 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 computing power increase type and computing power increase parameters to the virtual machine simulator via the communication message body. The virtual machine simulator increases the computing power resources of the virtual machine based on the computing power increase type and computing power increase parameters. For example, if the current processor utilization of the virtual machine is greater than a preset utilization rate, the computing power configuration type is a message type for increasing processors, and the resource configuration information includes parameters such as the number of processors to be increased.

[0058] For example, if an application running on the current virtual machine is running smoothly and the current computing power of the virtual machine 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 communication message body. The virtual machine simulator reduces the computing power resources of the virtual machine according to 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 a message type for reducing processors, and the resource configuration information includes parameters such as the number of processors to be reduced.

[0059] Based on the above embodiment, in an application embodiment, as shown in FIG3 , the application architecture package of the above virtual machine management method is composed of three parts: (1) an application running in the user space of the guest virtual machine (Guest VM); (2) a driver running in the kernel space of the Guest VM; and (3) a virtual machine simulator QEMU running on the host machine. The Guest VM communicates with the Virtio driver and its corresponding virtualization driver based on the Peripheral Component Interconnect (PCI) bus, i.e., the Virtio-PCI device.

[0060]

[0060] The user space application transmits 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: 1. Header: a fixed 8-byte header used to mark the type of the message; 2. Payload: a variable length payload used to transmit the actual payload information of the message, such as operation and maintenance data or configuration parameters.

[0061]

[0061] The communication message is transmitted in the kernel space to the virtual machine controller QEMLH on the host through the virtual queue Vring. 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.

[0062] The kernel space driver transmits messages in a synchronous manner. That is, after the kernel space driver sends a message, it blocks the sending of subsequent messages until it receives the return value of the current message from the virtual machine simulator QEMU. The second message will be written. When the message arrives at QEMLH, QEMU extracts the message and calls different processing logic according to the message type contained in the message header. Finally, the return value is written to Vring.

[0063]

[0063] 2. The operation and maintenance solution based on the communication architecture includes: 1. The guest virtual machine GuestVM applies for a piece of memory space with continuous addresses through a driver; 2. The guest virtual machine writes the address and storage capacity of the memory space into the payload data Payload of the communication message, and further transmits it to the virtual machine emulator QEMU through Vring.

[0064] The guest virtual machine reads and writes operation and maintenance information: GuestVM writes the information required by QEMU (such as the IOPS of the process in the guest virtual machine) to the agreed location in the memory space, and can also read the operation and maintenance information written by QEMU from the agreed location.

[0064]

[0065] 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.

[0065]

[0066] Through the above technical means, the present disclosure 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 the message delay.

[0066]

[0067] 3. The resource allocation solution based on the communication architecture includes the following: the guest VM notifies the virtual machine emulator of its resource requirements through the aforementioned communication framework. The virtual machine emulator dynamically allocates resources to the guest VM based on the policy. The following uses processors as an example: When the application within the guest VM is experiencing computing power shortages, it sends a message to QEMU requesting processing resources, requesting an increase in the number of processors. The message type is stored in the message header, and the number of processors requested is stored in the payload. After receiving the message, QEMU increases the number of processors in the guest VM based on the number of processors in the payload.

[0067]

[0068] When the application in the guest VM is running smoothly, it can request processing resources by sending a message to QEMU with the "Reduce Processor Count" message type. The message type is stored in the message header, and the requested number of processors is stored in the payload. After receiving the message, QEMU reduces the number of processors in the guest VM based on the number of processors in the payload.

[0068]

[0069] Through the above technical means, the present disclosure 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.

[0069]

However, those skilled in the art should understand that the present invention is not limited by the order of the actions described, as certain steps may be performed in a different order or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in this specification are preferred embodiments, and the actions and modules involved are not necessarily required for the present invention.

[0070]

[0071] According to another aspect of an embodiment of the present disclosure, a virtual machine for implementing the above-mentioned virtual machine management method is further provided. As shown in FIG5 , the virtual machine includes: a receiving unit 502, configured to receive a communication message sent by an application running on the virtual machine for managing the virtual machine; a first writing unit 504, configured to write the communication message into a virtual queue, so that a virtual machine simulator corresponding to the virtual machine obtains the communication message from the virtual queue; the virtual queue is a data link connecting a driver of the virtual machine and a driver of the virtual machine simulator.

[0071]

[0072] In an embodiment of the present disclosure, a method is adopted for receiving communication messages sent by an application running on the virtual machine for managing the virtual machine; writing the communication messages into a virtual queue, and the virtual machine simulator corresponding to the virtual machine obtaining the communication messages 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; the present disclosure does not need to degrade 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.
