Description

Intelligent fusion cloud desktop server, client and system

Technical Field

The invention relates to a cloud desktop system, in particular to an intelligent integrated cloud desktop server, a client and a system.

Background

Traditionally, cloud desktop refers to a virtual machine in which a desktop system (windows or linux) of a user is installed on a server, and the effects of unified management, dynamic issuing and operation, flexible allocation and recovery of the desktop system of the user are achieved by using flexibility brought by a virtualization technology. A typical technology of a conventional cloud Desktop is a VDI (Virtual Desktop Infrastructure) Virtual Desktop architecture, that is, a centralized deployment, centralized operation mode, and a thin terminal remote connection mode.

With the gradual maturity of hardware Virtualization capability on a PC platform, intel corporation has proposed an innovative framework IDV (Intelligent Desktop Virtualization) Intelligent Desktop Virtualization, which is different from the VDI mode in that all Desktop computing resources are highly centralized in a data center and an interface is sent to a terminal device, and the IDV adopts more distributed operations to meet the operation technical requirements, and simultaneously centralizes and simplifies management and deployment functions. The IDV has the advantages that the calculation resources are local, better video experience can be provided, the capabilities of 3D operation, peripheral compatibility and the like can be better supported, and the continuous operation can be realized when the network is interrupted.

Offline use is made very difficult by the centralized deployment, centralized operation, and remote connection features of VDI technology, which include early costs, storage-related technical challenges, uncertain TCOs, and in many cases network dependence. Also, VDI has some limitations on the variety of available peripherals, and peripherals that consume large amounts of bandwidth resources also expose problems arising at low bandwidths.

Although IDV solves the problems of network dependency, high bandwidth, unavailable offline, etc. in VDI mode, it also brings the requirement for the virtualization capability of PC hardware, and it must be used on Intel Broadwell and later CPUs relatively smoothly.

In summary, both the early VDI model and the later IDV model have disadvantages, which cannot perfectly meet the requirements of the user scenario, and the requirement of architecture and computing power for the design used by the user results in the waste of assets of the enterprise or organization.

And in the Idv mode, the second computer downloads the image file to the storage device of the second computer through the p2p technology, and then starts the downloaded image through the virtual machine and presents the operating system. And in the virtual mirror image mode, the second computer downloads the mirror image of the server side to the storage device of the second computer through a P2P technology, then restarts the second computer, and then directly starts a virtual mirror image operating system through a bootloader, so that no virtual machine runs locally.

The second computer program, when executed by the processor, implements the steps of:

a, obtaining hardware parameters of a client, wherein the hardware parameters comprise a CPU (Central processing Unit) model, whether a network card is communicated and whether VT-x, VT-d and AMD-V technologies are supported;

step3, acquiring a virtualization mode corresponding to the currently obtained virtual mirror image through a network, and if the virtualization mode is a VDI mode, executing Step4; if the virtualization mode is the IDV mode, executing Step5; if the virtualization mode is the virtual mirror mode, step6 is executed;

after the linux system is started by Step4 and bootloader software, starting a remote connection client, and completing mounting after the remote connection client is connected to a server;

And redirecting the access to the local disk of the client side to the disk of the virtual machine through the Hook disk operation, ensuring that the file can be normally identified when the operating system is started until the virtual disk drive in the operating system in the virtual disk is started, taking over the real disk reading and writing, giving the operating system the control right of the disk at this moment, exiting the Hook and completing the mounting.

In this embodiment, as shown in fig. 1, the image file is stored in a remote server, and is connected to the image of the server in a VDI mode by means of a remote protocol, where the existing general remote connection protocol includes spice, rdp, and the like. And downloading the image file to a local boot in the IDV mode. The virtual mirror image mode is started by loading a bootloader through bare hardware metal and then loading a virtual mirror image file by the bootloader.

In this embodiment, the bootloader is first run, and the network module is loaded to connect to the network.

Secondly, the server is connected through a network, if the network card is not communicated, whether the downloaded virtual mirror image or the IDV desktop exists locally or not is judged, if yes, the virtual machine mirror image is started preferentially, and then the IDV desktop exists.

And then if the network card is normal, the connection server sends the local MAC address to the server, and the server fuses the mirror image module to send the mirror image mode which is stored in the database and is suitable for starting to the bootloader. After the Bootloader receives the message, if the idv desktop is started, the Bootloader starts a linux system, and a virtual machine is started in the linux;

if the desktop is the vdi desktop, the bootloader starts a linux system, then starts a remote connection client and is connected to a virtual machine at the back end;

if the virtual mirror image is the virtual mirror image, the mirror image is mounted in a mode of loading bootloader by bare hardware metal;

if the starting mode does not exist, the terminal hardware information is obtained again, the judgment is made according to the table 1, and the hardware information and the judgment result are reported to the server and stored in the database.
