Description
Technical Field
The invention belongs to the technical field of computers, relates to a virtualized desktop computer system, and particularly relates to the field of single-computer host multi-operating system and multi-user desktop virtualization use.
Background
The existing computer use mode is generally a single-computer host single-user mode. When a plurality of people need to use the computer at the same time: the mode has the defects of high hardware acquisition cost, low hardware resource utilization rate, high management and maintenance cost, high electric quantity consumption, poor transverse expansion capability of a single host and the like.
A virtual cloud desktop mode using a cloud host and a thin client terminal is also available in the market. In the mode, the image displayed by the client terminal needs to be subjected to host compression, network transmission, client decompression and client display steps, so that the mode has the defects of low host resource utilization rate and poor user experience. This approach also has the disadvantage of high upfront hardware acquisition costs, since it also requires the purchase of a thin client terminal.
In addition, computer dragging software is also used in the market to achieve the purpose of using a single machine and multiple users, and because multiple users share one operating system in the mode, the defects of system conflict and data confidentiality among multiple users exist.
Disclosure of Invention
The virtual cloud desktop system overcomes the defects that in the using process of a computer under a multi-user scene, the utilization rate of hardware resources is low, the purchase cost of hardware is high, the electricity consumption is high, the management and maintenance cost is high, the user experience of the virtual cloud desktop system is poor, data leakage is caused under the condition of single operating system and multiple users, and the like. The invention provides a method for virtualizing a plurality of client operating systems which can be independently used at the same time on a host system by adopting a virtualization technology, wherein the image data displayed by the client system is directly output to a graphic display card for displaying by skipping a graphic window synthesizer of the host system, and each client system independently uses a mouse and a keyboard in a USB transparent transmission mode. The system achieves the purposes of simultaneously and independently using multiple operating systems of a single computer host and multiple users, thereby reducing the acquisition cost of hardware, reducing the management and maintenance cost, reducing the power consumption, having high user use experience, being convenient for management and deployment and allocating client resources according to the requirements.
The technical scheme adopted by the invention for solving the technical problems is as follows: the single computer host is externally connected with a plurality of sets of usb mice and usb keyboards through usb interfaces, is externally connected with a plurality of displays through a multi-screen display card or a common display card, then simultaneously virtualizes a plurality of client operating systems which can be simultaneously and independently used on the host by utilizing virtualization technology, and the client system displays image data and skips a graphic window synthesizer of the host system to be directly output to a graphic display card for displaying. Each client system independently uses independent USB external devices such as a USB mouse and a USB keyboard through a USB transparent transmission mode, and each client system independently uses independent display devices. Hardware devices such as a CPU, a memory, a storage, a network, a mouse, a keyboard, a display, a U disk, a printer and the like used by the client system are uniformly managed and distributed by virtualization software.
The host can be a common notebook computer, a common desktop computer and a special computer server.
The display card can be an integrated display card, a common display card, a multi-screen display card, a USB external display card and a virtual special display card.
The mode of the client system using the host system graphics card may be that the client system does not use the host graphics card, the client uses the host graphics card in a direct mode, and the client uses the host graphics card in a full virtualization mode of the graphics card (for example, full virtualization of intel graphics card, AMD or Nvidia dedicated virtualization graphics card).
The client display image data can be synthesized by a client CPU, an Intel integrated display card full virtualization synthesis, a virglrender synthesis, a special virtualization display card synthesis and a client after the display card is directly connected.
The client display image data is directly output to the display card. If the image data displayed by the client is output to the display card through the window synthesizer of the host system, the resource consumption of the CPU and the display card of the host system can be increased, thereby causing the situation of high resource consumption of the host.
The client system audio may be directly output to the host computer analog audio output, or may be audio output to the display device with audio input through the video card HDMI (or DP port, lightning port).
Each client system described above uses a mouse, keyboard, display alone. Mouse, keyboard and display are not conflicted among the clients. The mouse and the keyboard of the client system can use a host transparent transmission mode, a software redirection mode and a software virtual mode. The client system displays are administratively assigned by the virtualization hypervisor.
The client display image data is directly output to the display through the display card, and is transmitted to the terminal through the network in a non-virtual cloud desktop mode and then displayed. The client system display frame rate can be up to 30Hz, 50Hz, 60Hz, 75Hz, 144Hz supported, unlike the 30Hz commonly employed by virtual cloud desktops.
The display resolution of the client system can reach 1080p, 2k and 4k, unlike 1080p which is commonly adopted by a virtual cloud desktop.
The invention has the beneficial effects that the virtualization technology is adopted to simultaneously virtualize a plurality of client operating systems for a plurality of users to simultaneously and independently use, thereby effectively solving the defects of high management cost, high hardware acquisition cost, host resource waste, high electric quantity consumption, poor transverse expansion capability and data leakage in a single-system and multi-user mode in the traditional single-host and single-user mode. The client system displays image data and directly outputs the image data to the graphic display card for displaying by skipping a graphic window synthesizer of the host system, and the client system independently uses a mouse and a keyboard in a USB transparent transmission mode, so that the defects of poor user experience and high hardware acquisition cost of the virtual cloud desktop system are effectively overcome.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic view of the present invention;
FIG. 2 is a schematic diagram of displaying client image data to a host graphics card;
Detailed Description
[ example 1 ]
In the actual use case, the number of users is not constant, so the description is made in terms of the number of users being 3.
The hardware system and the software system are shown in fig. 1.
Hardware equipment: the computer comprises a computer host, three displays, three USB interface mice, three USB interface keyboards, a display card with three display interfaces, and three display link lines. The mouse and the keyboard are connected to the computer host through the USB interface, and the three displays are connected to the display card of the computer host through display connecting wires respectively.
A software system: the system comprises a Linux operating system running on a host, three Windows 7 client operating systems generated by virtualization, a set of virtualization software and virtualization management software.
The method comprises the steps of establishing three virtual client systems by using virtualization management software, distributing a mouse, a keyboard, a CPU, a memory, a storage, a network and a display for the three virtual client systems, wherein the mouse and the keyboard of the client are distributed in a host USB transparent transmission mode.
The method for directly displaying the graphic display data of the client system to the display card comprises the following steps: a. the software judges whether the resolution of the data which needs to be displayed currently is equal to the resolution of the display which is used currently. b. And if the data are equal, the data are directly sent to the display card for display. c. And if not, judging whether the current display card supports automatic zooming of the display image. d. And if the display card supports automatic image zooming, the data is directly sent to the display card for displaying. e. And if the display card does not support automatic image scaling, the display data is scaled in an Opengl mode and then sent to the display card for display. The above displaying steps refer to the schematic diagram of displaying the client image data to the host graphics card in fig. 2.
The method for displaying the mouse of the client system to the display card comprises the following steps: because the current display card supports a hardware mouse mode, the hardware mouse mode does not need software to synthesize mouse data and display image data. Therefore, when the client system generates a mouse event, the display card end directly calls the interface function for moving the mouse position to process the mouse event so as to fulfill the aim of displaying the mouse to the display card.
