[0018] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0019] For the related technology, the server side can only select one driver version (such as GPUU driver version) when the environment is deployed, and is limited by the driver version. For example, each driver version only supports one type of cloud desktop operating system. In addition, each cloud desktop manufacturer can only adapt and support the corresponding desktop operating system according to the driver support list provided by the graphics card manufacturer. As a result, the related technology cannot achieve downward or upward compatibility with different operating systems in a cloud desktop environment, and some operating systems that cannot be adapted need to be discarded.

[0020] In this regard, the present application provides an operating system switching method, an electronic device and a computer-readable medium, which can switch between different computing nodes through a management node to achieve the purpose of simultaneously supporting multiple versions or types of operating systems in the same cloud desktop environment, thereby meeting the user's needs for using different operating systems in different scenarios and improving the user experience.

[0021] like Figure 1 As shown, it is an architecture diagram of a communication system for implementing the technical solution of the present application provided by an embodiment of the present application. The system may include but is not limited to a cloud desktop management platform (usmartview), a management node (also referred to as a virtualization management center (Virtualization Management Center, VMC), also referred to as a management node server), multiple computing nodes (also referred to as computing node servers or hosts), and an authorization server (License server).

[0022] The cloud desktop management platform, as an operation and maintenance portal, can have built-in different versions of GPU virtualization drivers. For example, users can set different versions of virtual GPU (vGPU) drivers for different computing nodes on the cloud desktop management platform page. It can be understood that each virtual GPU driver is obtained by virtualizing the physical GPU drivers configured on different computing nodes. For example, in the cloud desktop scenario, the GPU driver (or graphics card) in the computing node can be virtualized into a virtual GPU driver and provided to the desktop operating system for use.

[0023] Management node, responsible for virtualization management, such as providing the function of switching the GPU virtualization driver version of the computing node.

[0024] Computing nodes are responsible for providing computing resources and GPU resources to run virtual machines, such as GPU virtualization functions that can support different desktop operating systems. In this application, different computing nodes can be configured with different operating systems (such as win7, win10, kylin, UOS, etc.) and physical GPUs (or hardware GPUs) that are compatible with the operating systems.

[0025] The authorization server is used to provide authorization requests with vGPU. For example, the authorization server can load different vGPU drivers according to the GRID license version included in the authorization request. For example, GPU virtualization requires the desktop operating system to obtain the authorization license from the authorization server before it can load the GRID driver normally.

[0026] A cloud desktop operating system is a cloud desktop using a vGPU. In this application, each computing node may correspond to a cloud desktop operating system (e.g. Figure 1 Windows 7 desktop, Windows 10 desktop, Kylin / UOS desktop, etc. shown). Optionally, in this application, the cloud desktop operating system and the corresponding computing node can be deployed on one physical node or on different physical nodes respectively, without limitation.

[0027] It is worth noting that the GPU mentioned in the context of this application is relative to the central processing unit (CPU) in the computer system. As people's demand for graphics is increasing, especially in home systems and game enthusiasts, and traditional CPUs cannot meet the current situation, it is necessary to provide a core processor dedicated to processing graphics. As the "heart" of the hardware graphics card, the GPU is equivalent to the role of the CPU in the computer system.

[0028] In addition, the aforementioned communication system is only an example. In actual application, the communication system may include Figure 1 This application does not limit the number of network units to more or less.

[0029] In this case, based on the information provided by this application Figure 1 The communication system shown in the embodiment of the present application also provides a Figure 2The method 200 for switching an operating system shown in the figure can be executed by a management node. In other words, the method 200 can be executed by software or hardware installed in the management node. The management node includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc. Figure 2 As shown, the method 200 may include the following steps.

[0030] S210, receiving a driver switching command initiated by a cloud desktop management platform.

[0031] There are many ways to initiate the drive switching command, for example: Figure 1 As shown, when the cloud desktop management platform can display multiple different versions of GPU virtual drivers, the driver switching command can be initiated by the user based on one of the different versions of the GPU virtual drivers according to the needs, wherein the GPU virtual driver is obtained by virtualizing the physical GPU (also referred to as the physical GPU driver). In this embodiment, the GPU virtual driver corresponds to the physical GPU driver one by one.

[0032] It is worth noting that the cloud desktop management platform and the management node can be deployed on the same physical node, or the cloud desktop management platform and the management node can be deployed on different physical nodes, which is not limited here.

[0033] S220: Switch between different computing nodes according to the drive switching command.

[0034] Among them, different computing nodes are respectively configured with different operating systems and physical GPUs adapted to the operating systems. Therefore, by switching between different computing nodes, switching between different operating systems can be achieved, thereby achieving the purpose of a cloud desktop environment being able to simultaneously support multiple different versions or types of operating systems, solving the problem in the related technology that a cloud desktop environment can only support one desktop operating system adapted to this version of the GPU virtualization driver, meeting the user's needs for using different desktop operating systems in different scenarios, and improving the user experience.

[0035] Based on this, in one implementation, when the management node switches between different computing nodes according to the driver switching command, it can determine the target GPU driver (the target GPU driver corresponds to one of multiple different versions of GPU virtual drivers) according to the driver switching command, and then send a switching request to the target computing node, and the switching request carries the target GPU driver. The target computing node belongs to the different computing nodes and is deployed with a target operating system, and the target GPU driver is adapted to the target operating system.

[0036] Correspondingly, when the target computing node receives the switching request sent by the management node, it can install and run the target GPU driver, so that the target computing node can run the target operating system based on the target GPU driver, thereby achieving the purpose of switching the operating system. It can be understood that the target GPU driver is adapted to the target operating system deployed on the target computing node, and the target computing node belongs to multiple different computing nodes, and different computing nodes are respectively configured with different operating systems and physical GPUs adapted to the operating system.

[0037] In one implementation, before installing and running the target GPU driver, the target computing node may first determine whether the target GPU driver is consistent with the GPU driver already installed on the target computing node. If the target GPU driver is inconsistent with the GPU driver already installed on the computing node, the installed GPU driver may be uninstalled, and the steps of installing and running the target GPU driver may be performed to achieve smooth installation of the target GPU driver. Otherwise, the target GPU driver is ignored, that is, the target operating system is directly run based on the installed target GPU driver. Thus, the GPU driver installation process can be avoided, and the operating system switching efficiency can be greatly improved.

[0038] In one implementation, if a virtual machine running the target operating system (i.e., cloud desktop operating system) is deployed on the target computing node, then the target computing node can also obtain a virtual machine driver (such as a GRID driver) after determining that the target GPU driver has been installed, and install the virtual machine driver in the virtual machine through a virtual machine agent to achieve the purpose of running the target operating system based on the virtual machine. It can be understood that a virtual GPU driver corresponding to the cloud desktop operating system can be deployed in the virtual machine.

[0039] Among them, before executing the step of installing the virtual machine driver in the virtual machine through the virtual machine agent, the target computing node may also first determine the type of the target operating system running in the virtual machine. If it is determined that the type of the target operating system is compatible with the virtual machine driver, the installed virtual machine driver is uninstalled.

[0040] Of course, in the scenario where a virtual machine is configured on the target computing node to run a cloud desktop operating system (corresponding to the aforementioned target operating system), in order to improve the reliability of the virtual GPU operation, in this application, the cloud desktop operating system can also obtain authorization from the authorization server to load the virtual machine driver. In one implementation, the authorization server can support authorization management of virtual machine drivers corresponding to multiple different cloud desktop operating systems.

[0041] In the embodiment of the present application, by switching the GPU virtualization driver through the management node, the same GPU cloud desktop environment can be upwardly or downwardly compatible with different operating system versions or types, so that the same cloud desktop environment can simultaneously support multiple operating systems of different versions or types, thereby meeting the user's needs for different operating systems in different scenarios and improving the user experience.

[0042] In addition, based on the operating system switching solution provided by this application, customers with multiple operating system requirements do not need to build multiple environments, reducing costs and improving the efficiency of environmental operation and maintenance; and this application reuses the existing communication architecture and adopts a flexible desktop system switching method, which can meet more customer usage scenarios and expand the customer group and scope of application of cloud desktop GPU virtualization.

[0043] Based on the description of the switching method 200 of the aforementioned operating system, as shown in FIG. Figure 3 As shown, a switching solution for an operating system is provided by an exemplary embodiment of the present application, and its implementation process is as follows.

[0044] S301, assuming that the cloud desktop platform displays multiple different versions of GPU virtual drivers, when the user needs to switch the operating system, a driver switching command can be initiated based on the target GPU virtual driver among the multiple GPU virtual drivers displayed on the cloud desktop management platform.

[0045] S302: The management node receives and responds to the driver switching command, and determines a target GPU driver according to the driver switching command.

[0046] S303: The management node sends a signal carrying the target GPU driver switching request to the target computing node.

[0047] S304, when the target computing node receives the switching request, it determines whether the target GPU driver carried in the switching request is consistent with the installed GPU driver. If they are consistent, the process ends and the target operating system can be directly run; if they are inconsistent, execute S305.

[0048] S305, the target computing node uninstalls the installed GPU driver (such as . / NVIDIA-Linux-x86_64-***-vgpu-kvm.run--uninstall), and after uninstalling the installed GPU driver, installs the target GPU driver, such as (1) chmod+xNVDIA-Linux-x86_64-***-vgpu-kvm.run; (2). / NVDIA-Linux-x86_64-***-vgpu-kvm.run.

[0049] S306: The target computing node installs a virtual machine driver (ie, a GRID driver) into the virtual machine through a virtual machine agent.

[0050] S307: Determine the type of the target operating system running in the virtual machine.

[0051] S308, install the GRID driver according to the type of the target operating system. For example, if it is a Windows operating system (also called a Windows virtual machine), uninstall the installed GRID driver (such as msiexec.exe / X{***} / qb) and install a new GRID driver (such as msiexec / i***_grid_64bit_international.exe / qb).

[0052] If it is a Linux operating system (also called a Linux virtual machine), uninstall the installed GRID driver (such as . / NVDIA-Linux-x86_64-***-grid.Run--uninstall), and install a new GRID driver (such as . / NVDIA-Linux-x86_64-***-grid.Run).

[0053] S309, the target computing node is registered to the authorization server through the virtual machine. It can be understood that different versions of operating systems such as Windows and Linux can share the same authorization server, so the process ends and the target operating system can be directly run.

[0054] It can be understood that the implementation process of the aforementioned S301-S309 can refer to the relevant description in the aforementioned method embodiment 200. In order to avoid repetition, it will not be repeated here. However, it should be noted that the desktop operating system provided in this application may include but is not limited to the aforementioned S301-S309, and may include more or fewer steps than the aforementioned S301-S309.

In other words, the method 400 can be executed by software or hardware installed in the target computing node. The target computing node includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc. Figure 2 As shown, the method 400 may include the following steps.

[0056] S410, receiving a switching request sent by a management node, wherein the switching request carries a target GPU driver;

[0057] S420: Install and run the target GPU driver.

[0058] The target GPU driver is adapted to the target operating system deployed on the target computing node, the target computing node belongs to a plurality of different computing nodes, and different computing nodes are respectively configured with different operating systems and physical GPUs adapted to the operating systems.

[0059] Optionally, the method also includes: determining whether the target GPU driver is consistent with the GPU driver already installed on the target computing node; if the target GPU driver is inconsistent with the GPU driver already installed on the computing node, uninstalling the installed GPU driver, and executing the steps of installing and running the target GPU driver.

[0060] Optionally, a virtual machine running the target operating system is deployed on the target computing node, and the method further includes: obtaining a virtual machine driver when it is determined that the target GPU driver is installed; and installing the virtual machine driver in the virtual machine through a virtual machine agent.

[0061] Optionally, the method also includes: determining the type of the target operating system running in the virtual machine; when determining that the type of the target operating system is compatible with the virtual machine driver, uninstalling the installed virtual machine driver, and executing the step of installing the virtual machine driver in the virtual machine through the virtual machine agent.

[0062] It can be understood that each implementation method in the present method embodiment 400 has the same or corresponding technical features as the aforementioned method embodiment 200. Therefore, the implementation process of each implementation method in the present method embodiment 400 can refer to the relevant description in the aforementioned method embodiment 200, and achieve the same or corresponding technical features. To avoid repetition, it will not be repeated here.
