[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The virtual machine management uninstallation method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the host HOST communicates with the data processing unit DPU. In this application, the storage and management of the virtual machine are offloaded from the host HOST to the data processing unit DPU, wherein the data processing unit DPU is a hardware device specially designed to process data-intensive tasks, and its purpose is to reduce the burden on the CPU of the host HOST, so that the computing resources of the host HOST are more used for the virtual machine, and the overall performance of the system is improved.

[0048] Among them, in this application, the storage and management of the virtual machine are offloaded from the host HOST to the data processing unit DPU, without modifying the original software of the host HOST and occupying the original storage resources of the host HOST; the embodiment of this application takes the virtual machine management software libvirt as an example to illustrate, and other open source or private virtual machine management software can also be unloaded to the data processing unit DPU according to this method; the embodiment of the virtual machine monitor hypervisor in this application takes QEMU as an example to illustrate, and other open source or private hypervisor software such as xen, qemu-kvm, kvm-tool, etc. can also be processed in this way.

[0049] Among them combined Figure 1 As shown, virtio-fs is used between the host HOST and the data processing unit DPU to realize file sharing; the host HOST and the data processing unit DPU share the same file source through virtio-fs; the file source is located in a third-party storage location or in the local storage of the data processing unit DPU to avoid intrusion into the storage resources of the host HOST. Virtio-fs is a file sharing technology. The operating system of the host HOST supports and comes with a virtio-fs driver. This technology can be used without modifying the operating system; according to the characteristics of virtio-fs, the host HOST can operate the shared files of the data processing unit DPU like operating the local file system; the host HOST uses virtio-fs supported by the data processing unit DPU to realize virtio-fs shared files.

[0050] The host HOST further includes a command execution component server and a virtual machine monitor, and the data processing unit DPU further includes a command execution component client and virtual machine management software. The virtual management software in this embodiment is described by taking libvirtd as an example, wherein the virtual management software runs on the data processing unit DPU and is pulled up after the system on chip of the data processing unit DPU is powered on.

[0051] The command execution component server and the command execution component client communicate through virtio-vsock. The executable files of the command execution component server are stored in the shared file directory. In this way, the storage, startup and management of the command execution component server are all in the data processing unit DPU, without changing the host HOST, reducing the impact on the HOST.

[0052] Optionally, for some private clouds, the command execution component server may be a kernel module in the host.

[0053] In addition, offloading in this application refers to transferring a target from one location to another.

[0054] In an exemplary embodiment, Figure 2 As shown, a virtual machine management uninstallation method is provided, and the method is applied to Figure 1 Taking the data processing unit DPU in the example as an example, the method includes the following steps S202 to S204. Among them:

[0055] S202: Acquire a shared file directory, and mount the shared file directory on the host when the host loads a driver of the data processing unit, and the host and the data processing unit share a file source through the shared file directory.

[0056] The shared file directory is unloaded to the data processing unit DPU. The file source corresponding to the shared file directory can be located in a third-party storage location or in the local storage location of the data processing unit DPU. No specific limitation is made here. It is only necessary to ensure that the shared file directory is unloaded to the data processing unit DPU.

[0057] One way to create a shared file may include: on the host HOST side: in the DPU driver loading process, the DPU driver reads the configuration information of the shared file from the data processing unit DPU, and uses the mount (command for mounting the file system, which is explained in English as attach the file system found on some device to the Unix system) method to set the virtio-fs shared file directory on the host HOST according to the configuration information. On the data processing unit DPU side: after the data processing unit DPU is powered on, if the system-on-chip of the data processing unit DPU uses the shared file directory provided by the local system, the shared file is directly operated. When the file source is located in a third-party storage location, the shared file directory provided by the remote system is used, and the corresponding file is obtained using technologies including but not limited to iscsi, rdma, etc.

[0058] Through the above method, the host HOST does not need to care about the storage location of the shared file directory, and can use it by just mounting it. Compared with the traditional nfs mounting and iscsi mounting, these implementation details are hidden in the data processing unit DPU, which improves security. Because for the host HOST, the virtio-fs device provided by the data processing unit DPU is used at this time to automatically load the driver.

[0059] S204: Storing the executable file of the command execution component server in the host in a shared file directory, wherein the executable file of the command execution component server is used for storage, startup and management of the command execution component server; the command execution component server communicates with the command execution component client in the data processing unit through virtio-vsock.

[0060] The command execution component may be a CMD component. In the present application, the command execution component includes two parts, a command execution component server CMD-Server and a command execution component client CMD-Client.

[0061] The executable file CMD-Server-bin of the command execution component server CMD-Server is located in the virtio-fs shared file directory and does not occupy the storage resources of the host HOST. The executable file of the command execution component server is used for the storage, startup and management of the command execution component server, so the host HOST does not need to manage the storage of the command execution component server CMD-Server, does not need to be responsible for the startup and management of the command execution component server CMD-Server, and is also conducive to upgrade and maintenance work.

[0062] In addition, the command execution component client CMD-Client runs in the data processing unit DPU, and the command execution component server CMD-Server runs in the host HOST; the command execution component client CMD-Client and the command execution component server CMD-Server communicate with each other through the virtio-vsock provided by the data processing unit DPU.

[0063] Virtio-vsock is a network communication device based on virtio. For the data processing unit DPU, it is implemented as a PCI device with independent vendor-id and device-id.

[0064] In this way, by utilizing the virtio-fs and virtio-vsock driver technologies natively supported by the host HOST system, as well as the virtio-fs, virtio-vsock, virtio-net, virtio-blk and other devices that come with the data processing unit DPU, the virtual machine management is offloaded from the host HOST to the data processing unit DPU. For diskless hosts HOST, the image provided by the data processing unit DPU can also be used to achieve diskless boot, which ultimately indirectly realizes the plug-and-play of the data processing unit DPU.

[0065] The virtio-fs and virtio-vsock drivers provided and supported by the host system are utilized to offload virtual machine management from the host to the data processing unit DPU. There is no need to modify the original software of the host, and there is no need for the host to actively manage related software.

[0066] The above-mentioned virtual machine management unloading method runs virtual machine management software in the data processing unit, runs a shared file directory, and obtains the shared file directory. When the host loads the driver of the data processing unit, the shared file directory is mounted on the host, and the host and the data processing unit share a file source through the shared file directory, so as to realize the storage of the virtual machine being unloaded to the data processing unit. In addition, the executable file of the command execution component server in the host is stored in the shared file directory, wherein the executable file of the command execution component server is used for the storage, startup and management of the command execution component server; the command execution component server communicates with the command execution component client in the data processing unit DPU through virtio-vsock, and both the host and the data processing unit DPU can operate on the shared file directory, and the executable file of the command execution component server in the host is stored in the shared file directory, that is, also in the data processing unit, without modifying the host, reducing the burden on the HOST host CPU, making the HOST computing resources more used for virtual machines, and improving the overall performance of the system.

[0067] In one of the optional embodiments, the method also includes: storing an executable file of the virtual machine monitor in a shared file directory, the executable file of the virtual machine monitor is used for storage, startup and management of the virtual machine monitor, and the virtual machine monitor is actively started by the host based on the executable file of the virtual machine monitor after the data processing unit driver is started.

[0068] The virtual machine monitor in this embodiment is described by taking QEMU (an open source virtual machine management software) as an example. The executable file QEMU-bin of the virtual machine monitor is located in the virtio-fs shared file directory and does not occupy the storage resources of the host HOST; the virtual machine monitor QEMU runs on the host HOST.

[0069] The virtual machine monitor QEMU startup includes: after the host HOST and the data processing unit DPU driver are started, the virtual machine monitor QEMU is actively pulled up. In this way, the host HOST does not need to manage the storage of the virtual machine monitor QEMU, and does not need to be responsible for the startup and management of the virtual machine monitor QEMU.

[0070] The virtual machine storage unloading includes the unloading of the storage pool and the unloading of the storage volume. The following will specifically introduce the process of unloading the storage pool and the unloading of the storage volume.

[0071] In one of the optional embodiments, in combination Figure 3 As shown, Figure 3 The flowchart of the unloading step of a storage pool in one embodiment includes:

[0072] S302: Create a storage pool directory in the shared file directory, and configure the storage pool directory in the storage pool configuration file.

[0073] Among them, the data processing unit DPU has created the virtio-fs shared file directory in the aforementioned manner. The system on chip of the data processing unit DPU and the software in the system can operate the shared file directory like operating local files. Therefore, the data processing unit DPU can create a storage pool directory in the shared file directory and configure the storage pool directory in the storage pool configuration file, such as the storage pool XML configuration file.

[0074] S304: Sending a storage pool creation command to the virtual machine management software running on the data processing unit through a command line interface tool for managing virtual machines.

[0075] The command line interface tool for managing virtual machines may be a tool such as virsh, which is not specifically limited here.

[0076] The data processing unit DPU sends a storage pool creation command to the virtual machine management software libvirtd through tools such as virsh. It should be noted that the virtual machine management software also runs in the data processing unit DPU.

[0077] S306: parsing the storage pool configuration file through the virtual machine management software, and creating a storage pool in the storage pool directory. The storage pool is dynamically managed by the command line interface tool.

[0078] The virtual machine management software libvirtd can parse the storage pool configuration file to obtain the storage pool directory and create the storage pool in the corresponding directory in the virtio-fs shared file system.

[0079] In addition, after the storage pool is created, the storage pool located in the virtio-fs shared file can be managed through tools such as the command line interface tool virsh.

[0080] This will offload the storage pool to the data processing unit DPU, reducing the storage resource usage of the host HOST.

[0081] In one of the optional embodiments, in combination Figure 4 As shown, Figure 4 The flowchart of the unloading step of a storage volume in one embodiment includes:

[0082] S402: Create a storage volume directory in the storage pool directory, and obtain a storage volume configuration file based on the storage volume directory.

[0083] Among them, the data processing unit DPU has created the virtio-fs shared file directory in the aforementioned manner. The system on chip of the data processing unit DPU and the software in the system can operate the shared file directory like operating local files. Therefore, the data processing unit DPU can create a storage volume directory in the storage pool directory in the shared file directory, and configure the storage volume directory in the storage volume configuration file, such as the storage volume XML configuration file.

[0084] S404: Send a storage volume creation command to the virtual machine management software running on the data processing unit through the command line interface tool.

[0085] The data processing unit DPU sends a storage volume creation command to the virtual machine management software libvirtd through tools such as virsh. It should be noted that the virtual machine management software also runs in the data processing unit DPU.

[0086] S406: parsing the storage volume configuration file through the virtual machine management software, and creating a storage volume in the storage volume directory. The storage volume is used by the host and is dynamically managed by the command line interface tool.

[0087] The virtual machine management software libvirtd can parse the storage volume configuration file to obtain the storage volume directory and create the storage pool in the corresponding directory in the virtio-fs shared file system.

[0088] In addition, after the storage volume is created, the storage volume located in the virtio-fs shared file can be managed through tools such as the command line interface tool virsh.

[0089] This will offload the storage volume to the data processing unit DPU, reducing the storage resource usage of the host HOST.

[0090] In this application, shared files are offloaded to the data processing unit DPU, and virtio-vsock is used to realize the communication between the command execution component server and the command execution component client, so that virtual machine management can be offloaded to the data processing unit DPU, wherein virtual machine management includes virtual machine creation and virtual machine life cycle management, and virtual machine life cycle management includes operations such as starting, stopping, pausing, snapshotting, migrating, and destroying virtual machines.

[0091] In one of the optional embodiments, in combination Figure 5 As shown, Figure 5 The flowchart of the steps of creating a virtual machine in one embodiment includes:

[0092] S502: Create a virtual machine directory in the storage volume directory, and obtain a virtual machine configuration file based on the virtual machine directory.

[0093] Among them, the data processing unit DPU has created the virtio-fs shared file directory in the aforementioned manner. The system on chip of the data processing unit DPU and the software in the system can operate the shared file directory like operating local files. Therefore, the data processing unit DPU can create a virtual machine directory in the storage volume directory in the shared file directory and configure the virtual machine directory in the virtual machine configuration file, such as the virtual machine XML configuration file.

[0094] S504: Sending a virtual machine creation command to the virtual machine management software running on the data processing unit through a command line interface tool.

[0095] The data processing unit DPU sends a virtual machine creation command to the virtual machine management software libvirtd through tools such as virsh. It should be noted that the virtual machine management software also runs in the data processing unit DPU.

[0096] S506: Parse the virtual machine configuration file through the virtual machine management software, and create the resources required for the virtual machine. Send a virtual machine creation message to the command execution component server through the command execution component client. The virtual machine creation message is used to instruct the command execution component server to obtain the virtual machine configuration file and call the virtual machine monitor command to create a virtual machine; the created virtual machine uses the corresponding storage volume to run.

[0097] The virtual machine management software libvirtd can parse the virtual machine configuration file and create the resources required by the virtual machine based on the virtual machine configuration file.

[0098] The command execution component client sends a virtual machine creation message to the command execution component server, so that the command execution component server obtains the virtual machine configuration file and calls the virtual machine monitor command to create a virtual machine; the created virtual machine uses the corresponding storage volume, so that the virtual machine is unloaded in the data processing unit DPU.

[0099] In the above embodiment, the virtual machine is offloaded to the data processing unit DPU, thereby reducing the occupation of storage resources of the host HOST.

[0100] In one of the optional embodiments, in combination Figure 6 As shown, Figure 6 The flowchart of the virtual machine management steps in one embodiment includes:

[0101] S602: Sending a virtual machine management command to the virtual machine management software running on the data processing unit through a command line interface tool.

[0102] The user can use tools such as virsh to send virtual machine management commands to the virtual machine management software libvirtd running on the data processing unit DPU.

[0103] The life cycle management of a virtual machine includes at least one of the following operations: start, stop, pause, snapshot, migrate, and destroy.

[0104] S604: Parse the virtual machine management command through the virtual machine management software, and send a virtual machine management message to the command execution component server through the command execution component client. The virtual machine management message is used to instruct the command execution component server to parse the virtual machine management message and call the virtual machine monitor to manage the virtual machine.

[0105] Among them, the virtual machine management software libvirtd parses the virtual machine management command, and sends the virtual machine management message to the command execution component server CMD-Server through the command execution component client CMD-Client; the command execution component server CMD-Server parses the virtual machine management message and calls the virtual machine monitor QEMU to manage the virtual machine.

[0106] In the above embodiment, the intrusion of the host HOST operating system by the traditional solution is eliminated; there is no need to modify the original software of the host HOST, and the host HOST does not need to actively manage related software, so that computing and IO virtualization are completely separated, so that all CPUs of the host HOST can be fully sold, and the management function is completely unloaded to the data processing unit DPU, which also improves the security level. For the situation where a data processing unit DPU is connected to multiple hosts HOST, storage space is also saved.

[0107] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
