[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] The embodiment of the present invention provides a first embodiment of a virtual machine management method, which is used in a BMC management system. Figure 1 as well as Figure 2 , Figure 1 A flowchart of a first embodiment of a virtual machine management method provided by an embodiment of the present invention is provided. Figure 2 A virtual machine management system provided by an embodiment of the present invention includes a BMC management system and a host machine, such as Figure 1 and Figure 2 As shown, the specific steps of this method are as follows:

[0034] In step S101, the BMC management system establishes connections with the host machine through the communication channels of the serial interface and the USB interface respectively, and sends a first instruction to the host machine through the communication channel of the serial interface to control the host machine to create a virtual machine and control the host machine to bind a USB device.

[0035] The BMC management system establishes a connection with the host computer through a data transmission channel, wherein the data transmission channel is divided into a serial interface communication channel and a USB interface communication channel.

[0036] The BMC management system establishes a serial port connection with the host machine. In a possible implementation, the BMC management system establishes a serial port connection with the host machine through a communication channel of a serial interface. The serial interface can be an RS232 device, and the communication channel of the serial interface can be an RS232 channel. Specifically, the BMC management system can be connected to the blade motherboard of the host machine. After the blade motherboard enters the system, it initializes the serial interface to enable the serial port service. The serial port service is used for the BMC management system to establish a serial port connection with the blade motherboard of the host machine through the communication channel of the serial interface. That is, based on the serial port service, the BMC management system establishes a serial port connection with the blade motherboard of the host machine through the communication channel of the serial interface.

[0037] In one possible implementation, a baseboard management controller (BMC control board) of a BMC management system can establish a serial port connection with a host machine based on a communication channel of a serial interface, and use the communication channel of the serial interface to send a first instruction to the host machine, where the first instruction is an instruction for the host machine to create a virtual machine, so as to control the host machine to create a virtual machine, and use the communication channel of the serial interface to control the host machine to bind a USB device.

[0038] The BMC management system uses the communication channel of the serial interface to control the host machine to create a virtual machine and control the host machine to bind a USB device, as shown in step S201:

[0039] Step S201: Using the communication channel of the serial interface, send the first instruction to the host machine and specify the USB device to be bound to the host machine. After receiving the first instruction, the host machine responds to the first instruction to create a virtual machine and bind the specified USB device.

[0040] The BMC management system uses the communication channel of the serial interface to send a first instruction to the host machine and specifies the USB device to be bound to the host machine. In one possible implementation, the USB device to be bound can be determined by the communication channel of the USB interface used to connect the BMC management system to the host machine. For example, if the communication channel of the USB interface used is a USB flash drive channel and a USB keyboard and mouse channel, the USB devices can be a USB flash drive and a USB keyboard and mouse.

[0041] After receiving the first instruction, the host machine responds to the first instruction to create a virtual machine and bind the specified USB device. In this embodiment, the host machine can create multiple virtual machines.

[0042] In a possible implementation, the BMC management system sets the USB device to device mode, so that the USB device is a USB device.

[0043] Step S102: The BMC management system mounts the ISO image file to the USB device bound to the host machine based on the communication channel of the USB interface, and sends a second instruction to the host machine through the serial interface to control the host machine to bind the USB interface to the corresponding virtual machine. The virtual machine is used to obtain the ISO image file in the USB device based on the USB interface and install the operating system of the virtual machine according to the ISO image file.

[0044] The BMC management system can store the ISO image file to the USB device corresponding to the USB interface, that is, the BMC management system mounts the ISO image file to the USB device bound to the host machine through the communication channel of the USB interface, and sends a second instruction to the host machine through the serial interface. The second instruction is an instruction to control the host machine to bind the USB interface to the corresponding virtual machine, so as to control the host machine to bind the USB interface to the corresponding virtual machine, so that the host machine maps the USB device corresponding to the USB interface to the virtual machine, so that the virtual machine can recognize the USB device, wherein the ISO image file contains the operating system installation file of the virtual machine. Since the host machine can create multiple virtual machines, the BMC management system needs to control the host machine to bind the USB interface to the corresponding virtual machine.

[0045] The specific steps for controlling the host machine to bind a USB interface to a corresponding virtual machine are as follows: the BMC management system mounts an ISO image file to the USB device bound to the host machine based on the USB interface's communication channel. The USB device starts the virtual machine. After the USB device starts the virtual machine, the BMC management system sends a second instruction to the host machine via the serial interface to control the host machine to bind the USB interface to the corresponding virtual machine. In one possible implementation, the BMC management system sets the virtual machine's BIOS startup item to be started by the USB device. The virtual machine's BIOS startup item is used to start the virtual machine. When the virtual machine's BIOS startup item is enabled by the USB device, the USB device starts the virtual machine.

[0046] In one possible implementation, the BMC management system mounts the ISO image file to the USB device bound to the host machine based on the communication channel of the USB interface, and controls the host machine to bind the USB interface to the corresponding virtual machine through the hypervisor layer.

[0047] The virtual machine obtains the ISO image file in the USB device. Since the ISO image file contains the virtual machine's operating system installation file, the virtual machine's operating system can be installed according to the ISO image file.

[0048] Based on the above method, in the absence of a network, the BMC control board is connected to the blade motherboard of the host machine through the serial port, and then the BMC management system communicates with the host machine through the serial port, issues a virtual machine creation instruction to the host system, and binds the specified USB device to the virtual machine. In addition, the BMC management system sets the corresponding USB device to the device type so that the virtual machine can recognize a USB devic device, and then mounts an ISO image file to the USB device device, thereby mapping the ISO image file to the USB device of the host machine. Finally, the host machine maps this USB device to the virtual machine through the virtualization hypervisor layer. Finally, when the virtual machine is turned on, the BIOS startup item is set to boot from the USB device. The virtual machine will recognize a USB storage device, thereby installing the operating system of the virtual machine.

[0049] The embodiment of the present invention provides a second embodiment of a virtual machine management method, which is used in a host machine, referring to Figure 3 , Figure 3 A flow chart of a second embodiment of a virtual machine management method provided by an embodiment of the present invention is shown as follows: Figure 3 As shown, the specific steps of this method are as follows:

[0050] In step S301, the host machine establishes connections with the BMC management system through communication channels of the serial interface and the USB interface respectively. The BMC management system is used to use the communication channel of the serial interface to issue a first instruction to the host machine. The host machine creates a virtual machine based on the first instruction and binds the USB device specified by the BMC management system.

[0051] The host machine establishes a serial port connection with the BMC management system. In a possible implementation, the host machine establishes a serial port connection with the BMC management system through a communication channel of a serial interface. The serial interface may be an RS232 device, and the communication channel of the serial interface may be an RS232 channel.

[0052] In one possible implementation, the host blade motherboard is connected to the BMC management system, and after the BMC management system initializes the serial interface to enable the serial port service, the host controls the blade motherboard to establish a serial port connection with the BMC management system through the communication channel of the serial interface based on the serial port service.

[0053] Specifically, the blade mainboard of the host machine can be connected to the BMC management system. After the blade mainboard enters the operating system, it initializes the serial interface to start the serial port service. The serial port service is used for the blade mainboard of the host machine to establish a serial port connection with the BMC management system through the communication channel of the serial interface. That is, based on the serial port service, the blade mainboard of the host machine establishes a serial port connection with the BMC management system through the communication channel of the serial interface.

[0054] In one possible implementation, a serial port connection can be established between the host machine and the BMC control board of the BMC management system through a communication channel based on a serial interface. The host machine uses the communication channel of the serial interface to create a virtual machine and bind a USB device.

[0055] The specific steps of creating a virtual machine and binding a USB device using the communication channel of the serial interface include steps S401 and S402:

[0056] Step S401: The BMC management system sends a first instruction to the host machine using the communication channel of the serial interface, and specifies the USB device to be bound to the host machine.

[0057] Step S402: The host machine receives the first instruction, and responds to the first instruction to create a virtual machine and bind the USB device specified by the BMC management system.

[0058] The BMC management system sends a first instruction to the host machine using a communication channel of a serial interface, specifying a USB device to be bound to the host machine. In one possible implementation, the USB device to be bound can be determined using the communication channel of the USB interface used by the BMC management system to connect to the host machine. After receiving the first instruction, the host machine responds to the first instruction, creates a virtual machine, and binds the specified USB device.

[0059] In a possible implementation, the BMC management system sets the USB device to device mode, so that the USB device is a USB device.

[0060] Step S302: The host machine controls the bound USB device to receive the ISO image file mounted by the BMC management system based on the communication channel of the USB interface, receives a second instruction issued by the BMC management system through the serial interface, and binds the USB interface to the corresponding virtual machine based on the second instruction; the virtual machine is used to obtain the ISO image file in the USB device based on the USB interface, and install the operating system of the virtual machine according to the ISO image file.

[0061] The BMC management system mounts the ISO image file to the USB device bound to the host machine through the communication channel of the USB interface, and sends a second instruction to the host machine through the serial interface. The second instruction is an instruction to control the host machine to bind the USB interface to the corresponding virtual machine, so as to control the host machine to bind the USB interface to the corresponding virtual machine, so that the host machine maps the USB device corresponding to the USB interface to the virtual machine, so that the virtual machine can recognize the USB device. The ISO image file contains the operating system installation file of the virtual machine.

[0062] Specifically, the BMC management system mounts the ISO image file to a USB device bound to the host machine using the USB interface's communication channel. The USB device then boots the virtual machine. After the USB device boots the virtual machine, the BMC management system sends a second instruction to the host machine via the serial interface, controlling the host machine to bind the USB interface to the corresponding virtual machine. In one possible implementation, the BMC management system sets the virtual machine's BIOS boot item to be booted by the USB device. The virtual machine's BIOS boot item is used to boot the virtual machine. When the virtual machine's BIOS boot item is enabled by the USB device, the USB device boots the virtual machine.

[0063] In one possible implementation, the BMC management system mounts the ISO image file to the USB device bound to the host machine based on the communication channel of the USB interface, and controls the host machine to bind the USB interface to the corresponding virtual machine through the hypervisor layer.

[0064] The virtual machine obtains the ISO image file in the USB device. Since the ISO image file contains the virtual machine's operating system installation file, the virtual machine's operating system can be installed according to the ISO image file.

[0065] The above describes how the BMC management system reinstalls the virtual machine operating system through serial and USB channels without a network connection. First, the BMC control board connects to the host machine's blade motherboard via the serial port. The BMC management system then communicates with the host machine through the serial port, issues a virtual machine creation command to the host system, and binds the specified USB device to the virtual machine. Furthermore, the BMC management system sets the corresponding USB device to the device type, allowing the virtual machine to recognize it as a USB device. It then mounts an ISO image file onto the USB device, mapping the ISO image file to the host machine's USB device. Finally, the host machine maps this USB device to the virtual machine through the hypervisor layer. Finally, when the virtual machine boots up, the BIOS boot item is set to boot from the USB device. The virtual machine recognizes the USB storage device, allowing the virtual machine's operating system to be installed.

[0066] In the present invention, when the BMC management system has no network, the BMC management system communicates and interacts with the serial port device and controls the USB device to bind and interact with the virtual machine, thereby realizing the function of installing the operating system of the virtual machine.

[0067] In order to better implement the above-mentioned virtual machine management method, the embodiment of the present invention also provides a virtual machine management device executed by the BMC management system, referring to Figure 4 , Figure 4 A structural block diagram of a virtual machine management device implemented by a BMC management system is provided in an embodiment of the present invention, such as Figure 4 As shown, the device 40 specifically includes:
