When the cloud desktops of the virtual machines are tested in batches, when the number of the virtual machines reaches hundreds or thousands of times, it is difficult to check whether the cloud desktop virtual machines are normally started one by manpower. The traditional method for ping the IP address of the virtual machine can only detect that the network of the virtual machine is normal, and can not detect when the desktop of the virtual machine has white screen, screen pattern or abnormal and wrong flick frame.
Disclosure of Invention
Accordingly, a primary object of the present invention is to provide a fault detection method for a virtual machine.
In order to achieve the above purpose, the technical scheme of the invention is realized as follows:
the embodiment of the invention provides a fault detection method of a virtual machine, which comprises the following steps: the method comprises the steps that a virtual machine template is created by a server according to a parameter configuration file and a preset normal desktop picture, a virtual machine is loaded by a terminal according to the virtual machine template, the configuration file is loaded by a client, a current desktop screen capturing picture of the virtual machine is compared with the preset normal picture to obtain comparison difference data, the comparison difference data and the desktop screen capturing picture are transmitted to the server, and whether the virtual machine is normal or not is judged by the server according to the comparison difference data and the desktop screen capturing picture.
In the above scheme, the terminal loads the virtual machine according to the virtual machine template, and the client loads the configuration file, and then the method further comprises: after the client detects that the virtual machine has started a specific program and has acquired an IP address, the virtual machine name, cpu, memory information are acquired and sent to the server.
In the above scheme, the comparison difference data is obtained by comparing the current desktop screen capturing picture of the virtual machine with the preset normal picture, specifically, the client captures the current desktop image through an imagegrab () method of the PIL library, and compares the current desktop screen capturing picture with the preset normal desktop picture through a histogram method to obtain the picture difference value a.
In the above scheme, the transmitting the contrast difference data and the desktop screenshot to the server is specifically: and sending the cloud desktop name, the current desktop screen capture picture and the difference value a of the virtual machine to a server through socket.
In the above scheme, the server judges whether the virtual machine is normal according to the contrast difference data and the desktop screenshot picture, specifically: and the server receives the desktop screen capturing picture, and the picture difference value a is larger than 0, so that the network of the virtual machine is confirmed to be normal but the desktop is abnormal.
In the above scheme, the server judges whether the virtual machine is normal according to the contrast difference data and the desktop screenshot picture, specifically: and the server receives the desktop screen capturing picture, and the picture difference value a is equal to 0, but cpu and memory information indicate that occupation is too large, and confirm that the load of the virtual machine is abnormal.
In the above scheme, the server judges whether the virtual machine is normal according to the contrast difference data and the desktop screenshot picture, specifically: and the server receives the desktop screen capturing picture, the picture difference value a is equal to 0, and the cpu and the memory information indicate normal, so that the virtual machine is confirmed to be normal.
In the above scheme, the method further comprises: and if the server does not receive the contrast difference data and the desktop screen capturing picture, confirming that the virtual machine is not started or the network is abnormal.
Compared with the prior art, the method and the device have the advantages that the desktop screen capturing picture of the virtual machine is compared with the normal desktop picture through the image histogram, the image equalization technology, the process detection and the socket data transmission, and whether the desktop of the virtual machine is normal or not is judged according to the difference value and the screen capturing picture.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the invention provides a fault detection method of a virtual machine, as shown in fig. 1, which is realized by the following steps:
step 101: the server creates a virtual machine template according to the parameter configuration file and a preset normal desktop picture;
specifically, a virtual machine template is created, a client program, a parameter configuration file and a preset normal desktop picture are placed in a specified directory, the client program is automatically operated after the starting-up is set, and virtual machines are created in batches through the virtual machine template.
The parameter configuration file comprises a server address, a port, a detection process name and waiting time.
Step 102: the terminal loads a virtual machine according to the virtual machine template, and the client loads a configuration file;
specifically, the client automatically runs and loads a parameter configuration file and a preset normal desktop picture; detecting whether a specific process of the virtual machine is started or not, and if the specific process is not started, waiting for a period of time and detecting again; and detecting whether the virtual machine network card is normal or not, acquiring the IP address, and waiting for a period of time to detect if the IP address is not acquired.
The specific process refers to reporting information to a server by means of the program.
After the client detects that the virtual machine has started a specific program and has acquired an IP address, the virtual machine name, cpu, memory information are acquired and sent to the server.
Step 103: the client compares the current desktop screen capturing picture of the virtual machine with a preset normal picture to obtain contrast difference data, and transmits the contrast difference data and the desktop screen capturing picture to a server;
specifically, the client intercepts a current desktop image through an imagegrab () method of a PIL library, and compares the current desktop screenshot picture with a preset normal desktop picture through a histogram method to obtain a picture difference value a.
And sending the cloud desktop name, the current desktop screen capture picture and the difference value a of the virtual machine to a server through socket.
Step 104: and the server judges whether the virtual machine is normal or not according to the contrast difference data and the desktop screen capturing picture.
Specifically, the server receives the desktop screenshot picture, and the picture difference value a is greater than 0, so as to confirm that the network of the virtual machine is normal but the desktop is abnormal.
And the server receives the desktop screen capturing picture, and the picture difference value a is equal to 0, but cpu and memory information indicate that occupation is too large, and confirm that the load of the virtual machine is abnormal.
And the server receives the desktop screen capturing picture, the picture difference value a is equal to 0, and the cpu and the memory information indicate normal, so that the virtual machine is confirmed to be normal.
And if the server does not receive the contrast difference data and the desktop screen capturing picture, confirming that the virtual machine is not started or the network is abnormal.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
