[0004] The cloud desktop client is connected with the KVM virtualization host through NAT (Network Address Translation) or gateway (not shown in the figure), and the transmission management data is mainly the data of the VDI protocol, including desktop graphics, voice, keyboard and mouse protocol data. In order to effectively isolate the management data of the management network and the service data of the service network, and ensure the safety of the management data of the VDI management platform, the cloud desktop virtual machine needs to have two virtual network cards for management data communication and service data communication.

[0016] Figure 2The flowchart of the method for implementing virtual machine management data communication provided by the embodiment of the present application includes the following steps:

[0017] Step 201, setting an agent for each virtual machine;

[0018] Step 202, creating a virtual hardware PCI device for each virtual machine;

[0019] Step 203, installing a virtual hardware PCI device driver for each virtual machine;

[0020] Step 204, running the virtual hardware PCI device driver by each agent, and communicating management data with the virtual desktop architecture management platform through the corresponding virtual hardware PCI device of the virtual machine.

[0021] Figure 2 The embodiment has the beneficial effect that the agent of each virtual machine connects the VDI management platform through the virtual hardware PCI device, and no longer needs a special management data IP address to communicate management data with the VDI management platform, thus simplifying the isolation of the management network data and the service network data of the virtual machine.

[0022] Figure 3 The figure is a schematic diagram of the virtual hardware PCI device of the cloud desktop virtual machine provided by the embodiment of the present application; on the server 1 carrying the cloud desktop virtual machine, an Agent Com Device (agent serial port device) simulated by a QEMU virtual machine is created on a KVM (Kernel-based Virtual Machine) virtualization platform, the Agent Com Device is a virtual hardware PCI device, an Agent data forwarding thread is added in the QEMU virtual machine, and the Agent data forwarding thread registers an interface to interact with the Agent Com Device.

[0023] After the cloud desktop virtual machine is started, the agent of the cloud desktop virtual machine starts running, the agent opens the Agent Com Device device through the driver interface of the installed Agent COM Device, and sends a connection control command with the IP address of the management platform to the Agent Com Device. After the Agent Com Device receives the connection control command, a socket connection is established with the VDI management platform of the server 2 through the network card of the IP address of the cloud desktop virtual machine, and the agent of the cloud desktop virtual machine communicates management data with the VDI management platform through the socket connection.

[0024] Figure 4 The figure is a cloud desktop network topology schematic diagram provided by the embodiment of the present application.

[0025] Figure 4 In the middle, after the cloud desktop virtual machine 1 starts, the Agent 1 opens the Agent Com Device 1 device through the installed Agent COM Device driver interface, and sends a connection control command with the management platform IP address to the Agent Com Device 1. After the Agent Com Device 1 receives the connection control command, it establishes a Socket connection with the VDI management platform through the virtual network card of the cloud desktop virtual machine IP address 192.168.0.3. The IP address 192.168.0 of the cloud desktop virtual machine 1 virtual network card is connected to the service network switch, and does not forward any management data packets.

[0026] After the cloud desktop virtual machine 2 starts, the Agent 2 opens the Agent Com Device 2 device through the installed Agent COM Device driver interface, and sends a connection control command with the management platform IP address to the Agent Com Device 2. After the Agent Com Device 2 receives the connection control command, it establishes a Socket connection with the VDI management platform through the virtual network card of the cloud desktop virtual machine IP address 192.168.124.1. The IP address 192.168.124.1 of the cloud desktop virtual machine 2 virtual network card is connected to the service network switch, and does not forward any management data packets.

[0027] Agent Com Device 1 and Agent Com Device 2 are virtual PCI devices with Send Buffer (virtual send buffer) and Recv Buffer (virtual receive buffer). The application takes Agent 1 communicating with the VDI management platform through Agent Com Device 1 as an example for illustration.

[0028] When the Agent 1 needs to send management data to the VDI management platform, the Agent reads the maximum cache length register, write address register and read address register of the virtual Send Buffer of the Agent Com Device 1, respectively obtains the maximum cache length (size), Write Index (write address index) and Read Index (read address index) of the virtual Send Buffer.

[0029] Agent 1 calculates the writable length (writable) according to the Write Index and Size of the virtual Send Buffer, and when the management data to be sent is less than the writable length, writes the management data to be sent to the virtual Send Buffer of Agent Com Device 1 according to the write address indicated by the Write Index. Agent 1 updates the Write Index of the write address register according to the new position of the virtual Send Buffer of Agent Com Device 1 being written.

[0030] The Agent 1 data forwarding thread reads the maximum cache length register, write address register and read address register of the virtual Send Buffer of Agent Com Device 1, respectively obtains the maximum cache length, Write Index and Read Index of the virtual Send Buffer.

[0031] The Agent 1 data forwarding thread calculates the length of the management data to be sent according to the Write Index and Read Index of the virtual Send Buffer, reads the management data of cloud desktop virtual machine 1 to be sent from the read address indicated by the Read Index, and sends it to the VDI management platform through the Socket connection. The Agent 1 data forwarding thread updates the Read Index of the read address register of the virtual Send Buffer according to the read address of the virtual Send Buffer of Agent Com Device 1 after being read.

[0032] When the VDI management platform sends management data to cloud desktop virtual machine 1, the VDI management platform sends the management data through the socket connection; the Agent 1 data forwarding thread reads the maximum cache length register, write address register and read address register of the virtual Recv Buffer of Agent Com Device 1, respectively obtains the maximum cache length (size), Write Index (write address index) and Read Index (read address index) of the virtual Recv Buffer.

[0033] The Agent1 data forwarding thread calculates the writable length based on the Write Index and Size of the virtual Recv Buffer. When the management data to be sent is less than the writable length, it writes the management data to be received into the virtual Recv Buffer of Agent Com Device1 according to the write address indicated by the Write Index. The Agent1 data forwarding thread then updates the Write Index of the virtual Recv Buffer's write address memory based on the position after the data is written into the virtual Recv Buffer of Agent Com Device1.

[0034] Agent1 reads the maximum buffer length register, write address register, and read address register of the virtual Recv Buffer from Agent Com Device1 to obtain the maximum buffer length, Write Index, and Read Index of the virtual Recv Buffer, respectively. Agent1 calculates the length of the management data to be read based on the Write Index and Read Index of the virtual Recv Buffer, and starts reading the management data from the read address indicated by the Read Index. The data forwarding thread of Agent1 updates the Read Index of the virtual Recv Buffer's read address memory based on the information obtained after the virtual Recv Buffer of Agent Com Device1 has been read.

[0035] The cloud desktop virtual machine 2 communicates with the VDI management platform through the same virtual hardware PCI device Agent Com Device 2 to manage data, which will not be described again. The cloud desktop virtual machine 2 can communicate with the VDI management platform to manage data through the virtual network card with IP address 192.168.124.1.

[0036] This application Figure 3 and Figure 4 By forwarding management data between the agent of the cloud desktop virtual machine and the VDI management platform through virtual hardware PCI devices, the management network and the business network are isolated. This avoids the complex implementation of isolation and forwarding of cloud desktop virtual machines through two virtual network cards and two virtual switches in the existing technology, and simplifies the isolation of virtual machine management network data and business network data.
