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: 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; specifically, an embodiment of the present disclosure provides a method for sharing a keyboard and mouse by a virtual machine, where the method may be applied to a system shown in fig. 1, and as shown in fig. 2, the method includes the following steps:
101. the first virtual machine and the second virtual machine are in communication connection, and the first virtual machine corresponding to the first zero terminal is directly controlled through a keyboard and a mouse.
In one embodiment, the communication connection established by the first virtual machine and the second virtual machine may include: TCP/IP communication connection. At this time, the first virtual machine and the second virtual machine are respectively provided with the IP addresses of the other parties, and the TCP/IP communication connection can be established according to the set IP addresses.
In actual implementation, the TCP/IP connection may be automatically established after the two virtual machines are started, or the TCP/IP communication connection between the two virtual machines may be manually established by a user.
Because only one set of keyboard and mouse is provided, 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 using process.
For example, in the using process, the keyboard and mouse master control right can be switched to the first zero terminal or the second zero terminal through a preset switching mode, 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.
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.
102. The first zero terminal receives a keyboard and mouse switching request message; and the keyboard and mouse switching request message indicates that the keyboard and mouse master control right is switched from the first zero terminal to the second zero terminal.
Wherein, the first zero terminal receives the key mouse switching request message, including: the first zero terminal receives a keyboard and mouse switching request message triggered by a user.
Illustratively, the first zero terminal receives a key-mouse switching request message triggered by a user through a shortcut key.
103. And the first zero terminal establishes communication connection with the second virtual machine.
104. And the first zero terminal directly sends the captured first keyboard and mouse signal to the second virtual machine.
105. The second virtual machine executes the first keyboard and mouse signal.
When the keyboard and mouse master control right needs to be switched to the second zero terminal to control the second virtual machine, the first zero terminal indicates that the keyboard and mouse master control right needs to be switched from the first zero terminal to the second zero terminal after receiving the keyboard and mouse switching request message, at this time, the first zero terminal can actively establish communication connection with the second virtual machine, and because the first zero terminal establishes communication connection with the second virtual machine, the first zero terminal can directly send the captured first keyboard and mouse signal to the second virtual machine, so that the second virtual machine locally executes the first keyboard and mouse signal to realize control over the desktop image.
Specifically, 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 a user to control the second virtual machine corresponding to the second zero terminal, and therefore the first zero terminal can directly send the captured first keyboard and mouse signal to the second virtual machine, and the first virtual machine and the second virtual machine can be simultaneously controlled by one set of keyboard and mouse.
The virtual machine sharing keyboard and mouse system provided by the embodiment of the disclosure comprises: the first virtual machine and the second virtual machine establish communication connection, and directly control the first virtual machine corresponding to the first zero terminal through a keyboard and a mouse; the first zero terminal receives a keyboard and mouse switching request message; the keyboard and mouse switching request message indicates that the keyboard and mouse master control right is switched from a first zero terminal to a second zero terminal; the first zero terminal establishes communication connection with the second virtual machine; the first zero terminal directly sends the captured first keyboard and mouse signal to a second virtual machine; the second virtual machine executes the first keyboard and mouse signal. Because can come two virtual machines of simultaneous control through one set of keyboard and 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 keyboard and mouse when operating different zero terminal, can improve user experience greatly.
In one embodiment, in order to notify the second virtual machine that the keyboard and mouse connected to the first zero terminal is about to control the second virtual machine, as shown in fig. 3, before the step 103, the method further includes the following steps:
106. and the first zero terminal sends the keyboard and mouse switching request message to the first virtual machine.
107. And the first virtual machine sends the keyboard and mouse switching request message to the second virtual machine.
After the first zero terminal receives the keyboard and mouse switching request message, because the first zero terminal does not establish communication connection with the second virtual machine at this time, and communication connection is already established between the first virtual machine and the second virtual machine, the first zero terminal firstly sends the keyboard and mouse switching request message to the first virtual machine, and then the first virtual machine sends the keyboard and mouse switching request message to the second virtual machine.
In one embodiment, as shown in fig. 3, the method further comprises the steps of:
108. and after receiving the key and mouse switching request message, the second virtual machine sends a key and mouse switching response message to the first virtual machine.
109. And after receiving the keyboard and mouse switching response message, the first virtual machine sends the connection information of the second virtual machine to the first zero terminal.
Suitably, the step 103 includes a sub-step 1031:
1031. and the first zero terminal establishes communication connection with the second virtual machine according to the connection information of the second virtual machine.
When wishing to switch the keyboard and mouse master control right to the second zero terminal, a first zero terminal user initiates a keyboard and mouse master control right switching request to the first virtual machine through a preset shortcut key, the first virtual machine receiving the keyboard and mouse switching request message initiates a keyboard and mouse switching request to the second virtual machine, and simultaneously receives a keyboard and mouse switching response message sent by the second virtual machine; after receiving the key mouse switching response message sent by the second virtual machine, the first virtual machine sends the connection information of the second virtual machine to the first zero terminal, so that the first zero terminal establishes communication connection with the second virtual machine according to the connection information of the second virtual machine, and the first zero terminal can directly send the first key mouse signal to the second virtual machine.
In one embodiment, as shown in fig. 4, the above step 1031 includes the following sub-steps:
10311. and the first zero terminal sends a keyboard and mouse message direct connection channel establishment request message to the second virtual machine based on the connection information of the second virtual machine.
10312. And the second virtual machine establishes a keyboard and mouse message direct connection channel between the second virtual machine and the first zero terminal according to the keyboard and mouse message direct connection channel establishment request message.
The method comprises the steps that a first zero terminal initiates a keyboard and mouse message direct connection channel establishment request to a second virtual machine based on connection information of the second virtual machine, the second virtual machine establishes the keyboard and mouse message direct connection channel with the first zero terminal after agreeing with the keyboard and mouse message direct connection channel establishment request, and meanwhile, the second virtual machine monitors a first keyboard and mouse signal sent by the first zero terminal on the channel.
By establishing a keyboard and mouse message direct connection channel between the first zero terminal and the second virtual machine, the first zero terminal can directly send a first keyboard and mouse signal for controlling the second virtual machine to the second virtual machine.
In one embodiment, as shown in FIG. 5, the above step 104 includes the following sub-steps:
1041. the first zero terminal converts the captured first keyboard and mouse analog signals into first keyboard and mouse digital signals; the first keyboard and mouse analog signal is used for controlling a keyboard and mouse signal of the second virtual machine.
1042. And the first zero terminal sends the first keyboard and mouse digital signal to the second virtual machine.
Because the first virtual machine and the second virtual machine can identify the numeric keyboard mouse signal, and the keyboard mouse signal triggered by the user through the keyboard mouse received by the second zero terminal is the first keyboard mouse analog signal, when the second zero terminal sends the first zero terminal, the first keyboard mouse analog signal sent by the user through the keyboard mouse is converted into the first keyboard mouse digital signal, and then the converted first keyboard mouse digital signal is sent to the second virtual machine, so that the second virtual machine executes the signal.
Specifically, the first zero terminal collects a keyboard and mouse analog signal generated in the keyboard and mouse operation process, converts the keyboard and mouse analog signal into a keyboard and mouse digital signal, and sends the keyboard and mouse digital signal to the second virtual machine through a keyboard and mouse message direct connection channel between the first zero terminal and the second virtual machine.
After the keyboard and mouse switching is completed, the user can control the second virtual machine through the keyboard and mouse device connected with the first zero terminal, namely, the desktop image received by the second zero terminal is controlled.
In actual implementation, during the key and mouse switching period, all the key and mouse messages collected by the first zero terminal are sent to the second virtual machine through the key and mouse message direct connection channel between the first zero terminal and the second virtual machine, and are not sent to the first virtual machine any more. Meanwhile, the second virtual machine only receives the keyboard and mouse messages sent by the first zero terminal, and simultaneously shields the keyboard and mouse messages sent by the second zero terminal.
And after receiving the keyboard and mouse digital signal sent by the first zero terminal, the second virtual machine locally executes the keyboard and mouse digital signal, thereby realizing the control of the second virtual machine, namely the control of the desktop image of the second zero terminal.
In the control process, if the keyboard and mouse master control authority is required to be switched again, the keyboard and mouse master control authority can still be switched through preset shortcut key operation, namely, the keyboard and mouse master control authority is switched on the current master control equipment through the shortcut key operation.
Specifically, as shown in fig. 6, the method further includes the following sub-steps:
1010. the first zero terminal receives a keyboard and mouse master control right recovery message triggered by a user; and the keyboard and mouse master control right recovery message indicates that the keyboard and mouse master control right is switched from the second zero terminal to the first zero terminal.
1011. And the first zero terminal disconnects the communication connection between the second virtual machine and the first zero terminal according to the keyboard and mouse master control right recovery message.
1012. And the first zero terminal establishes communication connection with the first virtual machine.
1013. And the first zero terminal sends the received second keyboard and mouse signal to the first virtual machine. The second keyboard and mouse signal is a signal for controlling the first virtual machine, that is, the second keyboard and mouse signal is a keyboard and mouse signal received after the first zero terminal disconnects the communication connection between the second virtual machine and the first zero terminal according to the keyboard and mouse master control right recovery message.
When the master control authority is switched back to the first zero terminal from the second zero terminal, the key mouse message direct connection channel between the current second virtual machine and the first zero terminal is directly cancelled, and all settings are restored to the state before key mouse switching.
In an embodiment, as shown in fig. 7, before the first zero terminal establishes the communication connection with the second virtual machine, the method further includes the following steps:
1014. the first zero terminal sends query request information to the first virtual machine, and the query request information requests the first virtual machine to query whether a second virtual machine is stored in a local preset trusted device list of the first virtual machine.
1015. After the first zero terminal receives the request response information of the first virtual machine, the first zero terminal establishes communication connection with the second virtual machine, and the request response information indicates that the second virtual machine is stored in a local preset trusted device list of the first virtual machine.
In order to ensure the reliability of the keyboard and mouse ownership switching, the first virtual machine and the second virtual machine are added into a trusted device list of the other party in advance.
Specifically, the information of the other party may be added to the trusted device lists of the first virtual machine and the second virtual machine in advance. Only the devices in the trusted list can be switched to the keyboard and mouse master control right.
When the keyboard and mouse master right is switched, after a first zero terminal receives a keyboard and mouse switching request message, a first virtual machine is made to inquire, at the moment, the first zero terminal sends inquiry request information for requesting the first virtual machine to inquire whether a second virtual machine is stored in a local preset trusted device list of the first virtual machine or not to the first virtual machine, the first virtual machine inquires that the second virtual machine is stored in the local preset trusted device list, then, the first virtual machine sends request response information for indicating that the second virtual machine is stored in the local preset trusted device list of the first virtual machine to the first zero terminal, and after the first zero terminal receives the request response information of the first virtual machine, the first zero terminal establishes communication connection with the second virtual machine.
In one embodiment, the first virtual machine establishes a communication connection with the second virtual machine, including: the first virtual machine establishes a TCP/IP communication connection with the second virtual machine.
For example, after the first virtual machine and the second virtual machine are started, a communication connection between the first virtual machine and the second virtual machine is established.
In actual implementation, the communication connection can be automatically established after the two virtual machines are started, or the user can manually trigger the establishment of the communication connection between the two virtual machines.
