Problems solved by technology

[0004] 1. USB mapping can only map USB recorders, and cannot be mapped to recorders connected through non-USB interfaces on desktops or laptops; 2. USB mapping is essentially an indiscriminate forwarding of USB commands. In actual use, Due to the complex interaction logic of the USB command itself, the burning process of the USB burner is extremely slow after using USB mapping; 3. USB mapping is a USB port mapping technology. After USB mapping, it is very easy to cause the USB port driver to discard the command due to command timeout, resulting in burning failure

Embodiment Construction

[0043] The technical scheme in the embodiment of the present application has the following general idea: recorders belong to SCSI devices in the classification of computer peripherals, and the communication between computers and recorders follows the SCSI protocol. Machine), and inform the virtual machine that the SCSI device is a recorder through SCSI commands, realize the data interaction between the virtual recorder and the virtual machine, obtain the SCSI commands generated by the virtual machine when using the virtual recorder, and then communicate with the physical recorder through SCSI commands Interact to realize the interaction between the physical recorder and the virtual machine, and achieve the purpose of recorder mapping (redirection).

[0044] Please refer to Figure 1 to Figure 3 As shown, a preferred embodiment of a burner redirection method for cloud desktops in the present invention includes the following steps:

[0045] Step S10, creating a virtual recorder...

Abstract

The invention provides a CD writer redirection method and a CD writer redirection system for a cloud desktop in the technical field of cloud desktops. The CD writer redirection method comprises the following steps of S10, creating a virtual CD writer on a virtual machine of a server; S20, after the virtual CD writer obtains physical equipment information and equipment capacity of a physical CD writer, the physical CD writer is initialized; and S30, a recording request of the virtual machine is redirected to a physical recorder by a virtual recorder, and read-write operation is performed by thephysical recorder. The invention has the advantages that the mapping compatibility, the recording speed and the stability of the recorder are greatly improved.

Description

technical field [0001] The invention relates to the technical field of cloud desktops, in particular to a burner redirection method and system for cloud desktops. Background technique [0002] Cloud desktop is an application of cloud computing technology, that is, through virtualization technology, a virtualization software is installed in the server in the data center computer room, and multiple servers with relatively independent CPU and memory are created by configuring the virtualization software. resource virtual machine. In this way, an actual server can be divided into multiple virtual machines, which can be provided to multiple users for independent use. Different users use different virtual machines, which will not seize CPU and memory resources from each other, and will not Machine operation conflicts with each other. In the cloud desktop application scenario, in order to meet the usage habits of most users, the virtual machine is generally installed with Windows...
