Embodiment 1
[0030] figure 1 It is a method flowchart of a data center load distribution and virtual machine migration energy-saving method provided by the first embodiment of the present invention, which includes steps 101 to 107.
[0031] Step 101, collect relevant data reflecting server resource utilization and energy efficiency ratio, and generate an overloaded server list;
[0032] This step monitors the running status and resource usage of the servers and virtual machines in the data center in real time, and regularly records the running status and resource utilization information of the servers, calculates the resource idleness of the servers and the energy efficiency ratio sequence of each server, and generates an overloaded server list ;
[0033] Step 102, select the virtual machine list VM to be migrated from the overloaded server list;
[0034] This step traverses the list of overloaded servers, selects the virtual machine with the highest priority on the list of overloaded se...
Embodiment 2
[0060] Please refer to Figure 4 , a data center load distribution and virtual machine migration energy saving system 100 provided by the second embodiment of the present invention, which includes:
[0061] Overloaded server list generation module 110, used to monitor the running status and resource usage of data center servers and virtual machines in real time, and regularly record the running status and resource utilization information of servers, and calculate the idle status of server resources and the energy efficiency ratio of each server sequence, generating a list of overloaded servers;
[0062] The first virtual machine list formation module 120 to be migrated is used for traversing the overloaded server list, selecting the virtual machine with the highest priority on the overloaded server list and requiring the smallest resource utilization rate to move out, and updating the server resource information, and then using the overloaded server The list generation module...
