Problems solved by technology

This method has wide compatibility with USB devices, but it limits the performance of high-performance USB devices. For example, the read and write performance of U disk can only reach 10% of the rated value, and only one terminal can be mapped to one cloud desktop, and multiple devices are not supported. Simultaneous access between cloud desktops, low mapping efficiency

Embodiment Construction

[0038] In a cloud computing environment that provides cloud desktops, refer to figure 1 , including a terminal 10, a host 20, and a virtual machine 30 provided by the host 20. The host 20 is installed with a cloud operating system and provides a virtual machine 30; the virtual machine 30 is installed with a desktop operating system, such as a Windows operating system; the Windows operating system supports RDP (Remote Desktop Protocol). During the remote communication process between the terminal 10 and the virtual machine 30 through the RDP protocol, the USB device inserted into the terminal 10 can be mapped to the cloud desktop of the virtual machine 30 .

[0039] refer to figure 2 , a terminal USB mapping method in an embodiment can be applied to a terminal communicating remotely with a virtual machine, and the method includes the following steps.

[0040] S110: When the insertion of the USB device is detected, obtain the device identifier of the inserted USB device, and ...

Abstract

The invention relates to a terminal USB mapping method, a virtual machine USB mapping method and system. The terminal USB mapping method comprises following steps: obtaining a device identifier of aninserted USB device and obtain the type of the USB device based on the device identifier; if the type is a network shareable device, identifying the inserted USB device based on the device identifier;enabling the network sharing mode of the identified USB device and obtaining the corresponding network device information; sending the network device information to the virtual machine, so that the virtual machine adds the network mapping device corresponding to the USB device according to the network device information; If the type is a non-network sharing device, establishing a data transmission channel between the inserted USB device and the virtual machine; receiving a USB data request sent by the virtual machine through the data transmission channel, and returning storage information corresponding to the USB device to the virtual machine according to the USB data request. In this way, the two mapping methods are combined, taking into account performance and compatibility, and the mapping efficiency is high.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a terminal USB mapping method, a virtual machine USB mapping method and a system. Background technique [0002] With the emergence of cloud computing technology, various cloud application products are gradually put into use, such as cloud desktops. Cloud desktop is a personal computer application based on cloud computing technology. Users need to remotely connect to the host that provides the virtual machine through a local terminal, and access the virtual machine through the host to obtain a virtual computer operation interface. Cloud desktops can replace personal computers for office or study, and an important part of covering user needs is the mapping of USB devices. [0003] The mapping function of the USB device used in the traditional cloud desktop is realized based on the remote desktop transmission protocol (ICA protocol, PCoIP protocol, RDP protocol, SPICE protocol), ...
