Description

Method and virtual machine for implementing application call

Technical field

This paper deals with the technology of implementing application calls, especially a method and virtual machine for implementing application calls between a terminal desktop and a virtual desktop.

Background technique

With the development of the Internet, cloud computing and virtualization technologies, great progress has been made in the field of virtual desktop technology, resulting in the concept of desktop virtualization, namely Virtual Desktop Infrastructure (VDI). The essence of VDI is one. It is also understood that the server-based client/server computing mode separates the personal computer environment from the physical device and stores all the data in a centralized large-scale storage device in the data center. It is a technology that supports enterprise-level remote dynamic access to desktop systems and unified hosting of data centers. The goal of VDI is to access any personal desktop system on the Internet from any location, at any time, through any terminal electronic device. The typical architecture of a virtual desktop system is generally a large virtual machine cluster in the background remote end. Each user needs a virtual machine to serve it; all terminal devices are finally connected to a gateway relay device through the Internet. And then distribute the virtual machine to the user.

VDI brings two advantages: On the one hand, administrators can deploy, host, and manage all desktop virtual machines in the Internet data center to reduce operation and maintenance costs; on the other hand, terminals that use electronic devices. Users can access virtual desktops over the network, gaining a similar experience to a complete physical PC (PC) desktop, reducing the physical hardware cost of the client.

Currently, the key technology used by VDI is the Desktop Transfer Protocol (also known as Network Display Protocol) and its implementation. Generally speaking, based on two processing methods: one is that Host Rendering, that is, all graphic image processing work of the virtual machine desktop is completed on the remote server, and only pixel information is sent to the user terminal. The user terminal does not need to perform a large number of operations, and eliminates the client design that requires high CPU and memory resources, and keeps the client structure simple. However, this processing method requires a large amount of network bandwidth. The other is client rendering (Client Rendering), that is, the client has a certain computing power, and undertakes part of the desktop graphics image computing As a result, desktop data can be compressed and transmitted to save network bandwidth.

Figure 1 is a block diagram of the virtualization architecture and components of the related technology X86 architecture server host. As shown in Figure 1, on the X86 architecture server host, based on the hypervisor virtualization engine, also known as the virtual machine monitor/manager (VMM, Virtual Machine Monitor), you can create and run multiple virtual machines (such as virtual machine 1, virtual machine 2... virtual machine N in Figure 1). Each virtual machine is similar to a physical PC, completely independent and isolated from each other. You can install various operating systems (GuestOS) required by users, such as Windows 8, Windows 7, various distributions based on the Linux kernel or commercial operating systems.

As shown in Figure 1, in the computing environment of the X86 architecture physical server hardware, the Hypervisor virtualization engine is an intermediate software layer running between the underlying physical server and the operating system, allowing multiple operating systems and their The application shares the hardware. Hypervisor is a "meta" operating system in a virtual computing environment that can access all physical device resources including CPU processor, memory, disk, and network card on the server host. Hypervisor not only can schedule and coordinate the access and allocation of these hardware resources, but also can isolate and protect each virtual machine at the same time. When the server starts and runs the hypervisor, each virtual machine can be allocated the right amount of CPU, memory, network and disk resources, and the virtual machine's GuestOS is loaded. Hypervisor is the core of all virtualization technologies. It manages the life cycle of virtual machines through Hypervisor. For example, one of its basic capabilities is to support non-disruptive online migration of virtual machines, so that virtual machines can be migrated from one host to another. On a host, the end user does not have any awareness during the process of using the virtual machine, and will not cause application or service interruption in the virtual machine.

The main types of X86 virtualization hypervisors on the market today include: virtual machines run directly on the system hardware, and hypervisors create instances of full hardware emulation, known as bare models. Or, the virtual machine runs on a traditional operating system, and the same hardware-simulated instance is created, which is called a hosted or hosted type. Alternatively, the virtual machine runs on a traditional operating system and creates a separate virtualized instance (container) that points to the underlying managed operating system and is referred to as "operating system virtualization." The most common one is still the bare-machine hypervisor. The virtualization kernel is installed directly on the hardware computing resources. The virtual machine and its GuestOS are installed and run on top of the hypervisor. The feature is that the hardware and software architecture and management are more efficient and flexible, and the performance of the hardware can be better utilized, thereby improving the utilization of computing resources, storage resources, and network resources on the physical server, and reducing operating costs. Industry Major vendors and products include Red Hat RedHat's RHEV, Citrix's XenServer, VMware's vSphere, Microsoft's Hyper-V, IBM's PowerVM, open source Xen, KVM, VirtualBox and other cores. Server virtualization product.

The virtual desktop technology is the desktop of the virtual machine operating system created and managed by the hypervisor, and is extended to the user's terminal local system for display, and the audio and video of the virtual machine is also redirected to the terminal output, and the end user's mouse is used. Human keyboard input operations such as keyboards, audio and video input operations such as recording and video recording, redirected to the virtual machine, and then presented and presented through the desktop of the virtual machine. The VDI virtual desktop transfer protocol or network display protocol is generally used to implement desktop remote and peripheral redirection. 2 is a block diagram showing the architecture and components of a related art virtual desktop. As shown in FIG. 2, a virtual desktop client program installed on a user terminal (such as a thin terminal, a PC, or a laptop) can access the enterprise hypervisor virtual. The server host and the virtual machines on it. The Hypervisor server host creates and manages virtual machines for device emulation of virtual machines. In the virtual machine, components such as virtual desktop agents, target stubs, and other drivers are deployed to enable message interaction and communication between the virtual desktop and the client program.

Virtual desktop technology provides end users with the means and methods to operate, use, and maintain virtual machine operating systems (OS), desktop systems, and installed applications on them, to achieve the same user experience and use as physical PC desktops. effect. Major vendors on the market today, including Open Source Virtual Network Computer (VNC) products, ZTE's VPlat products based on Remote Access Protocol (RAP); Red Hat RedHat's Simple Protocol based on Independent Computing Environment (SPICE) Technology RHEV products, Citrix's XenDesktop and XenApp products based on High Definition eXperience (HDX) and Independent Computing Architecture (ICA) technology, VMware's PCoIP-based View products, Microsoft's RDP-based and RemoteFX Technology virtual desktop products, etc.

Regardless of the virtualization engine or virtual desktop protocol of the related art, there is a problem that the guest OS in the virtual machine and the local terminal operating system of the user are independent, and various applications required by the user are deployed. In the guest OS of the virtual desktop and start running (this is the usage scenario and mode of most users of the virtual desktop), it is deployed in the terminal local system and starts running. In other words, the current various programs and products cannot be directly launched from the virtual desktop. An application originally installed in the terminal can not directly launch an application locally installed in the guest OS of the virtual desktop from the terminal. The terminal operating system refers to an operating system installed and operated by the user on terminals of various electronic devices (such as smart phones, smart pads, thin clients, laptops, PCs, etc.), such as Android, iOS, Windows series, and Linux. Series release or commercial version of the operating system. In this way, in some application scenarios with specific needs, the use of the virtual desktop is inconvenient, thereby limiting the application scenario of the virtual desktop. For example, some applications that are scheduled to be installed into a virtual machine require high resource consumption and real-time performance at runtime, which can significantly increase network stress. In the case of poor virtual machine configuration or insufficient network bandwidth, once the latency of the virtual desktop exceeds 50ms, a sensation will occur, which directly affects the performance of the virtual machine and the application experience, resulting in the experience of the virtual desktop user. Getting worse. At this point, it is not appropriate to install such an application deployment in a virtual machine, and it is installed in the local system of the user terminal to better meet the performance requirements. In this case, the calling method of such an application is to first install such an application locally on the user terminal, and when needed, it is necessary to repeatedly switch between the virtual desktop and the local desktop of the terminal to implement the call to the application. This greatly reduces the ease of use of the desktop and greatly reduces the user experience.

Techniques for copying and pasting operations. The drag operation is done with the help of the operating system. The object being dragged first registers the data format it uses with the operating system and provides the data in the specified data format. At the end of the drag operation, the program window of the dragged object is received, the relevant data is extracted according to the specified data format, and the corresponding object is generated according to the extracted data. The shortcut icon for dragging an application between the terminal desktop and the virtual desktop in the embodiment of the present invention is based on a mouse drag mechanism supported by the operating system.

The core idea of the embodiment of the present invention is to detect the user dragging and dropping on the desktop of the terminal system by using the mouse drag mechanism supported by the operating system and the desktop client deployed on the user terminal (the program component for accessing the desktop of the remote virtual machine). The operation of the shortcut icon, when the shortcut icon is dragged into the virtual desktop, the virtual desktop client program serves as a program window for receiving the dragged shortcut icon, through the virtual desktop protocol transmission channel, or socket (Socket) The method further sends the related attribute information of the extracted shortcut icon to the desktop agent in the virtual machine, and the desktop agent also creates a shortcut icon of the application corresponding to the dragged shortcut icon in the virtual desktop, and establishes the shortcut. The association between the mode icon and the target stub program enables a terminal-local application to be called from the remote virtual desktop (cloud desktop).

It should be noted that, in addition to the dragging method, you can also create a shortcut icon directly in the virtual machine, and then manually create the created shortcut icon and the terminal to specify the shortcut locally. The specific relationship of the icons is easy to implement for those skilled in the art, and details are not described herein again.

For applications that are not suitable for installation in a virtual machine, they can be installed locally on the terminal. On the one hand, the load on the virtual desktop is reduced, and the hardware and software resources of the terminal are fully utilized. On the other hand, the engineering deployment is increased.

The technical solution provided by the embodiment of the present invention allows a user to directly drag a shortcut icon of an application on a desktop of a terminal, such as a mouse or a touch screen, onto a virtual desktop of the virtual machine to establish a shortcut on the virtual desktop. The link relationship between the mode and the terminal application, thus quickly launching the application running the terminal directly from the cloud desktop. The technical solution provided by the embodiment of the present invention realizes the requirement that a certain terminal application can be quickly run from a virtual desktop (cloud desktop), and does not need to repeatedly switch between the virtual desktop and the local desktop of the terminal, thereby greatly Improved desktop usability.

FIG. 3 is a flowchart of a method for implementing an application call according to an embodiment of the present invention. As shown in FIG. 3, the method includes:

Step 300: The virtual machine obtains the attribute information of the specified shortcut icon on the local desktop of the terminal.

The step specifically includes: when the user drags the corresponding shortcut icon on the local desktop of the terminal, such as a *.lnk file, on the system desktop local to the user terminal, the virtual desktop client program installed and running on the user terminal will be The corresponding processing is performed. FIG. 4 is a flowchart of processing a virtual desktop client program of the user terminal in the embodiment of the method for implementing an application according to an embodiment of the present invention. As shown in FIG. 4, the method includes steps 400-405:

Step 400: Initialize and map the mouse dragging message processing function of the Windows, and implement the conventional technical means that are known to those skilled in the art, and details are not described herein again.

Step 401 to step 402: the virtual desktop client program performs tracking and detection by using a mouse dragging message processing function of Windows, and determines whether the mouse drag operation is released in the client area of the virtual desktop window, and if yes, proceeds to step 403; otherwise, End.

Among them, how to determine whether the mouse drag operation is in the client area of the virtual desktop window and release is a software programming technology that can be implemented according to the Win32 application programming interface (ie, API) provided by Microsoft Windows system, and the specific method can refer to the figure. Step 701 in 7. No longer here Narration.

Step 403: If the mouse is dragged into the virtual desktop window area, and the drag operation is ended to release the mouse button, it is determined that the user performs the operation of dragging the shortcut icon from the terminal desktop to the virtual desktop, and the virtual desktop client program obtains the dragged The file name corresponding to the shortcut icon,

Step 404: Call a component object model (COM) interface provided by the Windows system, and obtain attribute information of the shortcut icon according to the file name corresponding to the shortcut. The attribute information includes at least information such as a file name, a path, and an icon of the target application corresponding to the shortcut icon.

Step 405: The virtual desktop client program sends a notification message to the inside of the virtual machine, and carries the attribute information of the obtained shortcut icon.

In addition to the above-mentioned method of dragging, a shortcut icon can be created directly in the virtual machine, and then the corresponding relationship between the created shortcut icon and the terminal-designated shortcut icon can be manually created.

Optionally, if the mouse is not dragged into the virtual desktop window area, the mouse drag operation is not released in the window area of the virtual desktop, and the virtual desktop client program does not perform any processing, ending the tracking and detecting of the mouse drag event. .

The virtual desktop client program refers to a program component that is installed, deployed, and runs on the user electronic device terminal for accessing the remote virtual machine and the virtual desktop, and is generally presented as a window application.

Step 301: The virtual machine creates, on its virtual desktop, a shortcut icon of the virtual desktop corresponding to the specified shortcut icon.

FIG. 5 is a flowchart of a desktop agent processing process of a virtual machine in an embodiment of a method for implementing an application according to an embodiment of the present invention. As shown in FIG. 5, step 301 specifically includes the following steps 500-503:

Steps 500 to 501: The desktop agent deployed in the virtual machine runs in the background service mode, and after receiving the notification message from the virtual desktop client program, saves the attribute information carried in the virtual device, such as the shortcut name and the corresponding installation. The path, file name, etc. of the target application local to the terminal. In this way, the desktop agent knows that the end user has performed a drag operation at this time, and wants to drag the shortcut on the local desktop of the terminal to the virtual desktop of the remote virtual machine;

Step 502: The desktop agent calls the component object model provided by the Windows system. (COM) interface, creating a shortcut icon on the desktop of the virtual machine. The name of the shortcut icon is the same as the name of the shortcut on the terminal desktop. The shortcut icon can use the remote application icon provided by the Windows system, and correspondingly store the application stored in the terminal corresponding to the dragged shortcut icon. The file name and actual path of the program;

Step 503: Associate the shortcut icon created on the virtual desktop to the specified target stub program.

Those skilled in the art know that the target stub program and the desktop agent are pre-deployed inside the virtual machine and run as a Windows background service.

It should be noted that, in this step, the shortcut icon can use the remote application icon provided by the Windows system. Of course, the desktop agent can also create the virtual desktop by acquiring the icon file or icon data of the terminal application of the terminal desktop. The shortcut uses a shortcut icon that is identical to the shortcut icon for the terminal application, further enhancing the user experience and ease of use.

A desktop agent is a background server that is installed, deployed, and run in a virtual machine for processes such as message interaction processing, object creation, and association. The target stub program is similar to the desktop agent. It is also a background service program installed and running inside the virtual machine to complete the function of receiving, encapsulating and forwarding messages.

Step 302: When the virtual machine receives the shortcut icon command on the virtual desktop, the virtual machine corresponding to the shortcut icon is installed and installed in the terminal.

FIG. 6 is a flowchart of starting a local application from a remote virtual desktop in an embodiment of a method for implementing an application according to an embodiment of the present invention. As shown in FIG. 6, step 302 specifically includes the following steps 600-604:

Step 600: When the user double-clicks the shortcut icon corresponding to the application corresponding to the dragged shortcut icon from the virtual desktop, it indicates that the associated target stub program is triggered to run.

Step 601: The target stub program first obtains the file name and path of the corresponding terminal application saved in the shortcut icon, and the obtained file name and path are carried as parameter information in the startup notification message and sent to the desktop agent, and the terminal is desired to be started. application.

Step 602: After receiving the startup notification message, the desktop agent sends a notification message to the desktop client program deployed on the user terminal through the transmission channel of the virtual desktop protocol, and carries the above message. Parameter information.

Step 603: The desktop client program of the terminal starts the application running the terminal locally through the Win32 API interface of the related technology according to the application file name and path specified in the parameter information carried in the notification message.

Optionally, the method further includes a step 604: the desktop client program hides or minimizes the virtual desktop window of the terminal, so that the window or interface of the application local to the terminal can run on the virtual desktop window (or implement embedding of the parent and child windows). , fusion), to avoid being covered or occluded by the virtual desktop window, enhancing the ease of use. The disclosure of the present invention is not limited to the scope of protection of the present invention, and the details are not described herein.

Compared with the related technologies, the method of the embodiment of the present invention solves the problems and disadvantages that the virtual desktop application and the terminal local application existing in the related art are completely isolated and cannot be conveniently and quickly started, and is provided between the virtual desktop and the end user local. Quickly establish a technical solution for the application shortcut soft link, and achieve the purpose of directly launching the terminal local application in the virtual desktop without repeatedly switching between the virtual desktop and the terminal local desktop, thereby greatly improving the desktop user's Ease of use and convenience further enhance the automation of virtual desktops in terms of operation and use.

FIG. 7 is a schematic flowchart of an embodiment of a method for implementing an application call according to an embodiment of the present invention. In this embodiment, a hardware part is assumed to be composed of an X86 server host, a user terminal, such as a thin client, a PC, or a notebook computer. As shown by the dotted arrow in FIG. 8, when the user drags a shortcut icon from the system desktop of the local terminal and places it in the virtual desktop (the desktop of the remote virtual machine), as shown in FIG. 7, it includes:

Step 700: Add a function of supporting mouse dragging on the virtual desktop client program provided by the related technology virtual desktop, such as VDClient.exe, including: calling the Win32 API function DragAcceptFiles when the virtual desktop client program window is created or initialized. Or, through the Accept Files property of the Windows Integrated Development Environment Settings window, the virtual desktop client program window allows the operation of dragging files. Maps the Windows message WM_DROPFILES to handle mouse drag events in the message handler OnDropFiles.

Step 701: Call the Win32 API function GetClientRect to obtain the coordinates of the virtual desktop window client area, and then call the ClientToScreen function to convert the coordinates of the obtained virtual desktop client area to The screen coordinate system; the Win32 API function DragQueryPoint is used to obtain the position coordinates of the pointer when the drag operation ends and the mouse is released, thereby determining whether the dragged shortcut icon falls within the rectangular area of the window of the virtual desktop client program.

Step 702: If it is detected that the drag and drop is completed, the mouse is released, and the dragged shortcut icon falls within the rectangular area of the desktop client window, in the OnDropFiles message processing function, the Win32 API function DragQueryFile is called to obtain the shortcut of being dragged and dropped. The file name and path of the mode are saved; then, by referring to the IWshRuntimeLibrary function of the COM component, the WshShell and IWshShortcut objects are created, and various properties of the shortcut are obtained, including the installation path and file name of the target application corresponding to the shortcut in the terminal. .

Optionally, if the dragged-out shortcut icon does not fall within the rectangular area of the desktop client window when the drag-and-drop is completed and the mouse is released, in the OnDropFiles message processing function, the DragFinish function is directly called to release the memory allocated by the system and the end is can.
