Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
With the advance of technology, the terminal side will be developed towards more and more lightweight, that is, the terminal is configured to be lower and smaller.
At present, various zero terminal (ZC) solutions have been proposed, so-called zero terminals, i.e., terminals that only need to have a screen, a simple CPU and memory, an image receiving and decoding module for processing images, and a reverse control processing module. This solution enables a considerable simplification of the size and configuration of the mobile terminal. All programs of the zero terminal run in the cloud server, the zero terminal uses the corresponding application program by accessing the virtual machine distributed by the cloud server, the corresponding application program is controlled by reverse control, and the server sends the real-time processing picture to the zero terminal, so that the zero terminal operates as if the zero terminal is locally operated.
At present, in zero-terminal systems, there are often such usage scenarios: one user controls two pieces of zero terminal equipment at the same time, and needs to control the two pieces of zero terminal equipment. Under the circumstance, a user faces two displays, two virtual machines and two sets of key mice (keyboards and mice), and the two sets of key mice need to be frequently switched to control different virtual machines, so that the user is often in a busy and messy state in the scene, and the operation is very inconvenient.
The embodiment of the present disclosure provides a structure diagram of a virtual machine sharing keyboard and mouse system, as shown in fig. 1, the system includes: the system comprises two zero terminals (a first zero terminal and a second zero terminal), two virtual machines (a first virtual machine corresponding to the first zero terminal and a second virtual machine corresponding to the second zero terminal) and a keyboard and mouse set.
The embodiment of the present disclosure provides a method for sharing a keyboard and a mouse by a virtual machine, which may be applied to a first zero terminal in a system shown in fig. 1, as shown in fig. 2, and the method includes the following steps:
101. the first zero terminal and the second zero terminal are in communication connection, and a first virtual machine corresponding to the first zero terminal is directly controlled through a keyboard and a mouse.

At this time, the first zero terminal and the second zero terminal are respectively provided with the IP addresses of the other parties, and at this time, the TCP/IP communication connection can be established according to the set IP addresses.
In practical implementation, the TCP/IP connection may be automatically established after the two zero terminals are started, or the TCP/IP communication connection between the two zero terminals may be manually established by a user.
Because there is only one set of keyboard and mouse, after the computer is started, the keyboard and mouse master control right can be set to belong to the first zero terminal, and the keyboard and mouse master control right can be switched to the first zero terminal or the second zero terminal in the use process (for example, the keyboard and mouse master control right can be switched to the first zero terminal or the second zero terminal through a preset shortcut key in the use process).
At this time, since the keyboard and mouse master control right belongs to the first zero terminal, the first virtual machine corresponding to the first zero terminal can be directly controlled by the set of keyboard and mouse.
In one implementation, the keyboard and mouse can be connected to the first zero terminal in a wired or wireless manner.
The process of controlling the first virtual machine through the keyboard and the mouse is as follows: the first zero terminal converts the captured keyboard and mouse analog signals into keyboard and mouse digital signals, the keyboard and mouse digital signals are sent to the first virtual machine, and the first virtual machine locally executes the keyboard and mouse digital signals to control the desktop image.
102. And the first zero terminal sends a keyboard and mouse master control right transfer message to the second zero terminal. The keyboard and mouse master control right transfer message indicates that the keyboard and mouse master control right is switched from the first zero terminal to the second zero terminal.
When the keyboard and mouse master control right needs to be switched to the second zero terminal, the first zero terminal sends a keyboard and mouse master control right transfer message to the second zero terminal, and the keyboard and mouse master control right transfer message indicates that the keyboard and mouse master control right needs to be switched to the second zero terminal, namely, the second zero terminal needs to be controlled by the keyboard and mouse connected with the first zero terminal.
103. And the first zero terminal sends the captured first keyboard and mouse signal to the second zero terminal, so that the second zero terminal sends the first keyboard and mouse signal to the second virtual machine, and the second virtual machine is controlled by the keyboard and mouse.
After the keyboard and mouse master control right is switched, a first keyboard and mouse signal subsequently received by the first zero terminal is used for controlling the virtual machine corresponding to the second zero terminal by a user, so that the first zero terminal can send the captured first keyboard and mouse signal to the second zero terminal, the second zero terminal can send the first keyboard and mouse signal to the second virtual machine, and the second virtual machine can be controlled by the keyboard and mouse.
Wherein, the first zero terminal sends the captured first keyboard and mouse signal to the second zero terminal, including: and after the first zero terminal receives the key mouse master control right transfer response message, the first zero terminal sends the captured first key mouse signal to the second zero terminal.
After the first zero terminal sends a keyboard and mouse master control right transfer message to the second zero terminal, the second zero terminal returns a keyboard and mouse master control right transfer response message to the first zero terminal after receiving the keyboard and mouse master control right transfer message sent by the first zero terminal, and after the second zero terminal sends the keyboard and mouse master control right transfer response message, the second zero terminal can monitor a first keyboard and mouse signal sent by the first zero terminal.
After the first zero terminal receives the keyboard and mouse master control right transfer response message, the first zero terminal sends the captured first keyboard and mouse signal to the second zero terminal.

Because can come two virtual machines of simultaneous control through a set of key mouse, like this, when many zero terminal equipment of user simultaneous control, this kind of scheme can bring very big facility for the user, and the user need not go to frequently change different key mouse when operating different zero terminals, can improve user experience greatly.
