Problems solved by technology
[0002] With the increasing development of the cloud computing industry, in order to make cloud hosts run more efficiently and consume less energy, virtual machines are created in the form of image snapshots, but this technology brings about the problem of startup storms that start virtual machines in batches:
[0003] One is that the customer will start the virtual machine during working hours, and a black screen may appear at this time;
[0004] The second is that the virtual machines are opened in batches at the same time, causing network IO blocking problems;
[0005] The third is that simultaneous activation of virtual machines in batches will increase the load on the host machine, affecting the virtual machines and business operations on the host machine;
[0006] Fourth, the virtual machine fails to start, which affects the daily business operation of customers

Embodiment Construction
[0027] Such as figure 1 Shown, the basic steps of the present invention are:
[0028] Step 1: Add the virtual machine that needs to be powered on to the waiting queue;
[0029] Step 2: Dynamically calculate the average CPU load and network IO of the physical machine;
[0030] Step 3: Determine whether the two sets of data values in step 2 reach the preset peak value;
[0031] Step 4: On the premise of satisfying step 3, select a virtual machine according to the first-in-first-out and priority algorithms;
[0032] Step 5: Execute the boot command to let the thread enter the waiting state;
[0033] Step 6: Detect whether the boot is complete, if it fails, return to step 2;
[0034] Step 7: After the detection is successful, delete the power-on queue of the corresponding virtual machine.
[0035] Moreover, the dynamic calculation is to obtain N times of data, remove the two groups of lowest and highest values, and then calculate the average value of the remaining N-4 data....

The invention relates to the technical field of virtual machine management, in particularly to a method for defending cloud platform virtual machines against storm starting. Firstly, the virtual machines needing to be started in batches are combined into a locking queue; secondly, a current physical machine CPU load and network IO are dynamically calculated, if the two data do not reach preset peak values, one virtual machine high in priority is selected from the locking queue, and after a start-up command is executed, a thread sleeps for a period of time; finally, after start-up is successfully detected, the next virtual machine in the locking queue continues to be started. The method eliminates the situation that the virtual machines are started at the same time in batches and accordingly the black-screen phenomenon is caused, guarantees that the client environment can be used normally, and improves user experience.
