The embodiment of the application provides a remote desktop control method, which can be applied to computer equipment, wherein the computer equipment can include but is not limited to a physical machine and a virtualization chip.
The physical machine may include, but is not limited to, a first processor (i.e., CPU), a memory, and a motherboard, and an operating system is run on the physical machine. In addition, the physical machine may not include a storage resource such as a hard disk, and of course, the physical machine may also include a storage resource such as a local disk, which is not limited to this. In one example, the following description will be made by taking an example that the physical machine may not include a storage resource such as a hard disk.
In a conventional manner, a plurality of virtual machines are created on a physical machine, and the plurality of virtual machines share CPU resources, memory resources, storage resources, and the like of the physical machine, so that the virtual machines have problems of performance loss, resource contention, and the like.
Different from a conventional physical machine, the physical machine in the embodiment of the present application does not have a local Storage resource, that is, a Storage resource such as a hard disk is not deployed locally for the physical machine, but a cloud Storage device is used to provide a Storage resource for the physical machine, where the cloud Storage device may include, but is not limited to, a cloud disk, an NAS (Network Attached Storage) device, and the like, and the type of the cloud Storage device is not limited.
Therefore, all data read-write operations of the physical machine can be realized by accessing the cloud storage device, that is, when data is written, the data is written into the cloud storage device, and when data is read, the data is read from the cloud storage device. In summary, in the physical machine in the embodiment of the present application, if storage resources such as a local hard disk are not deployed, the physical machine is a stateless physical machine, that is, the physical machine itself does not store related data, and all data are stored in the cloud storage device. Therefore, when the physical machine fails, the physical machine can be migrated to another physical machine to continue to serve the tenant, but the tenant data does not need to be migrated, so that the physical machine can be rapidly migrated, the migration process is imperceptible to the tenant, the virtual machine migration advantage can be achieved, and the service experience of the virtual machine can be maintained.
In the embodiment of the application, the Hypervisor service can be transferred to a virtualized chip to be implemented, that is, the Hypervisor service is implemented on the virtualized chip, instead of the Hypervisor service being implemented on a physical machine, and the architecture in which the Hypervisor service and the physical machine are separated enables the physical machine not to implement the Hypervisor service, that is, data related to the Hypervisor service does not need to be stored locally. When a physical machine fails, data related to the Hypervisor service cannot be lost, when the data is migrated to another physical machine, the data related to the Hypervisor service in the virtualization chip can be migrated to a virtualization chip of another physical machine, the Hypervisor service is realized on the migrated virtualization chip, the rapid migration of the Hypervisor service is realized, the migration advantage of the virtual machine is achieved, the service experience of the virtual machine is maintained, and the elasticity of the virtual machine is achieved.
The Hypervisor service is an intermediate software layer running between a physical machine and an operating system, and can allow a plurality of operating systems and applications to share one set of basic physical hardware, so that the Hypervisor service can also be regarded as a 'meta' operating system in a virtual environment, and the Hypervisor service is the core of all virtualization technologies.
In the conventional Virtual Machine service, the Virtual Machine may provide the VNC service through a VMM (Virtual Machine Monitor), but in the embodiment of the present application, the Hypervisor service (such as QEMU (Virtual operating system simulator)) may be deployed in the virtualization chip instead of the Hypervisor service deployed in the physical Machine, and the VNC service may be implemented through the Hypervisor service (such as QEMU) in the virtualization chip, so as to provide the VNC access experience for the user.
Specifically, the virtualization chip may obtain desktop data of the physical machine, and provide the desktop data to the remote control device, so that the remote control device locally displays the desktop of the physical machine on the remote control device according to the desktop data. The virtualization chip can simulate the keyboard operation and the mouse operation of the remote control equipment, control the physical machine to execute the keyboard operation and the mouse operation of the remote control equipment, and complete the control of the physical machine.
Because the keyboard operation and the mouse operation of the remote control device are simulated on the virtualization chip, and the physical machine is controlled to execute the keyboard operation and the mouse operation of the remote control device, the BIOS (Basic Input Output System) and the OS (operating System) of the physical machine can be correctly operated with zero modification.
In one example, the virtualized chip may include, but is not limited to: an FPGA (Field Programmable Gate Array) chip and a second processor; or, an ASIC (Application Specific Integrated Circuit) chip and a second processor; or, SOC (System on Chip). For ease of distinction, a processor in a physical machine may be referred to as a first processor and a processor in a virtualized chip may be referred to as a second processor. Of course, the three implementation manners described above are only examples of implementing the virtualization chip, and the implementation manner of the virtualization chip is not limited as long as the VNC service can be implemented on the virtualization chip, and the virtualization chip can be interconnected with the physical machine.
If the virtualization chip is composed of an FPGA chip and a second processor, the FPGA chip is used for completing interconnection between the physical machine and the second processor, and the second processor is used for realizing the VNC service. If the virtualized chip is composed of an ASIC chip and a second processor, the ASIC chip is used to complete interconnection between the physical machine and the second processor, and the second processor is used to implement the VNC service. If the virtualized chip is composed of an SOC, the SOC is used for interconnecting with the physical machine, and the SOC is used for implementing the VNC service.
In one example, the connection between the virtualized chip and the physical machine may be: the virtualization chip is connected to the physical machine through the high-speed serial bus, and certainly, the virtualization chip may also be connected to the physical machine through other methods, which is not limited to this. Among these, the high-speed serial bus may include, but is not limited to: a PCIE (Peripheral Component Interconnect Express) bus. The high-speed serial bus may also be other types of serial buses, such as a fiber-based high-speed serial bus, and the like, without limitation.
In summary, the physical machine implemented in the above manner can use the CPU resource (i.e., the resource provided by the first processor) and the memory resource (i.e., the resource provided by the memory) independently, and there is no problem that a plurality of physical machines share the resource, so that the physical machine has the performance and high isolation of the physical machine, and the physical machine can be migrated quickly, has the migration advantage of the virtual machine, and maintains the flexible cloud deployment value of the virtual machine. Therefore, the computer device formed by the physical machine and the virtualization chip can be called as an elastic physical machine, and the elastic physical machine can support the advantages of rapid delivery, compatibility with virtual machine images, cloud storage device starting, cloud storage device hooking, migration and recovery of physical machine faults, automation of operation and maintenance and the like, and has high application value.
In one example, the above-described remote desktop control method may be applied to a system including a remote control device and a computer device, the computer device may include a physical machine and a virtualization chip, the remote control device is used to implement VNC client functions, and the virtualization chip is used to implement VNC server functions. Through the cooperation of the VNC client and the VNC server, the virtualization chip can realize VNC services.
For example, the virtualized chip may implement VNC services by deploying Hypervisor traffic (e.g., QEMU, etc.) on the virtualized chip. For example, based on Hypervisor traffic, a virtualization chip may include, but is not limited to, a VNC service module for interacting with a remote control device (e.g., a VNC client) and an input-output module for interacting with a physical machine.
Referring to fig. 1A, which is a schematic view of an application scenario of this embodiment, a physical machine includes a first processor, a memory, a motherboard, and an operating system, and a virtualization chip includes a VNC service module in communication with a VNC client and an input/output module in communication with the physical machine.

Referring to fig. 1C, when the virtualization chip is composed of an ASIC chip and a second processor, the second processor includes a VNC service module communicating with a VNC client, and an input-output module communicating with a physical machine. Referring to fig. 1D, when the virtualized chip is composed of an SOC, the SOC includes a VNC service module in communication with a VNC client, and an input-output module in communication with a physical machine.
Referring to fig. 2, which is a flowchart of a remote desktop control method according to an embodiment of the present disclosure, the method may be applied to a computer device, which may include a physical machine and a virtualization chip, and the method may include:
in step 201, a VNC service module of a virtualized chip receives a control request sent by a remote control device through a VNC client, where the control request carries operation information for performing remote desktop control.
In step 202, the VNC service module of the virtualized chip parses the operation information from the control request, executes an operation corresponding to the operation information, and sends an operation result to the input/output module of the virtualized chip. After the VNC service module performs an operation corresponding to the operation information, an operation result may be obtained.
And 203, the input/output module of the virtualization chip provides the operation result to the physical machine connected with the virtualization chip through a high-speed serial bus between the virtualization chip and the physical machine, so that the physical machine performs desktop control according to the operation result.
In an example, the execution sequence is only an example given for convenience of description, and in practical applications, the execution sequence between steps may also be changed, and the execution sequence is not limited. Moreover, in other embodiments, the steps of the respective methods do not have to be performed in the order shown and described herein, and the methods may include more or less steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps in other embodiments for description; multiple steps described in this specification may be combined into a single step in other embodiments.
The above remote desktop control method is described in detail below with reference to several specific embodiments.
In case one, the operation information is mouse action information, that is, the remote control device performs a mouse action.
In step 202, the process of performing the operation corresponding to the operation information for the VNC service module of the virtualized chip may include, but is not limited to: and the VNC service module simulates mouse operation corresponding to the mouse action information based on the mouse action information. Specifically, the mouse action information may include, but is not limited to: mouse pointer position information and mouse click information; based on this, the VNC service module of the virtualized chip may simulate a mouse operation corresponding to the mouse click information at a position corresponding to the mouse pointer position information.
In step 203, a process for "the input/output module of the virtualized chip provides the operation result to the physical machine, so that the physical machine performs desktop control according to the operation result" may include, but is not limited to: the input and output module of the virtualization chip can provide the result of the mouse operation to the physical machine, so that the physical machine responds to the mouse operation.
In one example, when the remote control device needs to perform desktop control on the physical machine, a mouse operation may be performed, and for this mouse operation, the remote control device may generate a control request, and the control request may carry mouse action information, which includes but is not limited to mouse pointer position information, mouse click information, and the like. For example, the mouse pointer position information may be (100 ), indicating that a mouse click operation is performed at the position (100 ) of the screen; the mouse click information may be a left mouse click, a double mouse click, a right mouse click, a double mouse click, etc., and the mouse click information is not limited in detail.
After the remote control device generates the control request, the remote control device may send the control request to the virtualization chip, and after receiving the control request sent by the remote control device, the VNC service module of the virtualization chip may parse mouse action information, such as mouse pointer position information (100 ), left mouse click, and the like, from the control request.
Then, based on the mouse action information, the VNC service module may simulate a mouse operation corresponding to the mouse action information. For example, based on mouse pointer position information (100 ), mouse left click, and other mouse action information, the VNC service module may perform a mouse left click operation at the position (100 ). The operation result corresponding to the operation is as follows: a left mouse click is performed at position (100 ).
Then, the input/output module of the virtualized chip may provide the operation result of the mouse operation (i.e., performing left mouse click at the position (100, 100)) to the physical machine, so that the physical machine may perform desktop control according to the operation result, i.e., the physical machine responds to the mouse operation. That is, the physical machine may perform one mouse left click at the location (100 ) of the local desktop in response to the mouse operation performed by the remote control device.
And in the second case, the operation information is keyboard action information, namely the remote control equipment executes keyboard action.
In step 202, the process of executing the operation corresponding to the operation information for the VNC service module of the virtualized chip may include, but is not limited to: and the VNC service module simulates keyboard operation corresponding to the keyboard action information based on the keyboard action information. Specifically, the keyboard action information may include, but is not limited to, a keyboard code; the VNC service module of the virtualized chip may determine a key corresponding to the keyboard code and simulate a keyboard operation corresponding to the key.
In step 203, the process of providing the operation result to the physical machine for the input/output module of the virtualized chip to enable the physical machine to perform desktop control according to the operation result may include, but is not limited to: the input and output module of the virtualization chip can provide the result of the keyboard operation to the physical machine so that the physical machine responds to the keyboard operation.
In one example, when the remote control device needs desktop control over the physical machine, a keyboard operation may be performed, for which the remote control device may generate a control request, which may carry keyboard action information, which may include, but is not limited to, a keyboard code, and the like. For example, when the user presses "a" of the remote control device, the keypad code carried by the control request is 65; when the user presses the 'B' of the remote control equipment, the keyboard code carried by the control request is 66; when the user presses the 'C' of the remote control equipment, the keyboard code carried by the control request is 67; in this way, each key of the keyboard corresponds to a unique keyboard code, and when a user presses a key, the control request can carry the keyboard code corresponding to the key.
The remote control device may send the control request to the virtualization chip after generating the control request, and the VNC service module of the virtualization chip may parse the keyboard action information, such as the keyboard code 65 and the keyboard code 66, from the control request after receiving the control request sent by the remote control device, which is not limited in this respect.
Then, based on the keyboard action information, the VNC service module of the virtualized chip may simulate a keyboard operation corresponding to the keyboard action information. For example, based on the keyboard operation information of the keyboard code 65, the operation of "a" for clicking the keyboard can be simulated, and the operation results are as follows: click on the character a. Based on the keyboard operation information of the keyboard code 66, the operation of "B" of clicking the keyboard can be simulated, and the operation results are as follows: click on character B. Based on the keyboard action information of the keyboard code 67, the operation of "C" for clicking the keyboard can be simulated, and the operation results corresponding to the above operations are: click on character C. By analogy, the VNC service module of the virtualized chip may simulate clicking each character of the keyboard and obtain an operation result.
Then, the input/output module of the virtualized chip may provide the operation result (i.e., the click character a, the click character B, etc.) of the keyboard operation to the physical machine, so that the physical machine may perform desktop control according to the operation result, i.e., the physical machine responds to the keyboard operation. That is, the physical machine may perform operations such as clicking on character a, clicking on character B, etc. on the local keyboard in response to keyboard operations performed by the remote control device.
And in the third case, the operation information is screen content acquisition information, namely the remote control equipment acquires screen data.
In step 202, the process of executing the operation corresponding to the operation information for the VNC service module of the virtualized chip may include, but is not limited to: the VNC service module generates a data acquisition request corresponding to the screen content acquisition information; the data acquisition request is used for acquiring desktop data of the physical machine.
In step 203, the process of providing the operation result to the physical machine for the input/output module of the virtualized chip to enable the physical machine to perform desktop control according to the operation result may include, but is not limited to: the input and output module of the virtualization chip provides the data acquisition request to the physical machine so that the physical machine returns desktop data of the physical machine; then, the input/output module of the virtualization chip receives the desktop data, sends the desktop data to the VNC service module of the virtualization chip, and the VNC service module sends the desktop data to the remote control device, so that the remote control device displays the desktop of the physical machine locally on the remote control device according to the desktop data.
In one example, when the remote control device needs to locally display the desktop of the physical machine, the remote control device may generate a control request, where the control request may carry screen content acquisition information, and the screen content acquisition information is used to acquire desktop data of the physical machine, that is, frame buffer information of the physical machine.
The remote control device may send the control request to the virtualization chip after generating the control request, and the VNC service module of the virtualization chip may parse the screen content acquisition information from the control request after receiving the control request sent by the remote control device. Because the screen content obtaining information is used for obtaining the desktop data of the physical machine, the virtualization chip may generate a data obtaining request corresponding to the screen content obtaining information, and the data obtaining request is used for obtaining the desktop data of the physical machine.
Then, the input/output module of the virtualization chip may provide the data obtaining request to the physical machine, so that the physical machine may respond to the data obtaining request after receiving the data obtaining request, that is, the physical machine may obtain the desktop data from the local and return the desktop data to the virtualization chip. Then, the input/output module of the virtualization chip may receive the desktop data, and send the desktop data to the VNC service module, and the VNC service module sends the desktop data to the remote control device, so that the remote control device displays the desktop of the physical machine locally on the remote control device according to the desktop data.
The desktop data may include, but is not limited to: frame buffer (frame buffer) information, wherein the desktop data is used for enabling the remote control device to locally display the desktop of the physical machine, that is, the desktop data is data corresponding to the current desktop of the physical machine, and the desktop of the physical machine can be displayed through the desktop data.
Based on the technical scheme, in the embodiment of the application, the physical machine and the Hypervisor service can be separated by deploying the physical machine and the virtualization chip, so that the performance and the high isolation of the physical machine are ensured, the elastic cloud deployment of the virtual machine is maintained, the physical machine has the elasticity of the virtual machine, and the quick deployment, the quick migration, the cloud disk starting, the cloud disk hooking and the automatic operation and maintenance of the physical machine can be supported. In the above manner, instead of creating multiple virtual machines on a physical machine, only the physical machine is deployed, so that the multiple virtual machines are not involved in sharing the CPU resources, the memory resources, and the storage resources of the physical machine, and problems such as performance loss and resource contention are avoided. Moreover, by implementing a VNC (Virtual Network Console) server function on the virtualization chip, the remote control device can control mouse operations and keyboard operations of the physical machine, and display a desktop of the physical machine on the remote control device, thereby providing VNC access experience for a user.
Based on the same application concept as the method, an embodiment of the present application further provides a remote desktop control device, which is applied to a computer device, where the computer device includes a physical machine and a virtualization chip, and the device is applied to the virtualization chip, as shown in fig. 3, and is a structure diagram of the device, and the device includes:
