Method and device for load balancing of resources of virtual machine

The embodiment of the invention provides a method and a device for load balancing of resources of a virtual machine. The method comprises the following steps of: if the obtained resource utilization rate within the future time preset by a local physical host is more than a set threshold value, transmitting a request message of inquiring the current resource utilization rate of other physical hosts in a virtual computing system to a proxy server; according to the received resource utilization rates of other physical hosts, acquiring a physical host list of which the resource utilization rate meets the operating requirement of a virtual host to be moved, which is operated on the local physical host; determining a destination movement physical host according to moving probabilities of all physical hosts in the physical host list and the resource utilization rates within the future time preset by all physical hosts in the physical host list; and moving the virtual host to be moved to the destination movement physical host. The embodiment of the invention has the advantages of avoiding unnecessary moving cost due to the temporary peak value of the resource utilization rate, saving network resources, solving the conflict problem caused by the cluster effect, and ensuring the stability of the virtual computing system.

Resource information processing method and resource information processing device

The invention provides a resource information processing method and a resource information processing device. The resource information processing method comprises the steps of pulling increment resource information every first preset time interval through an increment resource interface of each resource source; updating a resource information database according to the increment resource information; pulling total resource information every second preset time interval through a total resource interface of each resource source, wherein the second preset time interval is larger than the first preset time interval; and updating the resource information database according to the total resource information. The resource information processing method and the resource information processing device have advantages of realizing multi-channel resource aggregation, realizing no requirement of a user for video searching on different video websites, and settling a problem of tedious operation. Furthermore a relatively high increment updating frequency is realized, and in-time updating of latest resource information can be ensured. A total updating frequency is relatively low, but integrity of a resource information database can be ensured, and furthermore network resource can be saved.
