Embodiment
For making those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The scene of the present embodiment application mainly comprises following four kinds:
The first, when user creates virtual machine time, the resources balance mechanism of cloud computing can make computational resource and storage resources be assigned in different physical machine (HOST).
The second, when user restarts virtual machine time, cloud computing will the computational resource of balanced virtual machine and storage resources again, and now computational resource and storage resources are assigned in different physical machine.
3rd, under some abnormal conditions, such as fissure, the computational resource of virtual machine may occur from migration.
4th, when the physical machine of storage virtual machine mirror image delays machine, the storage resources of virtual machine also may occur from migration.
Wherein, the position fixing process of storage resources is in the present embodiment: according to the existing mechanism of Glusterfs, it is by a hash algorithm by the UUID of stochastic generation (general unique identifier), then obtain a physical machine list, thus determine the physical machine position at storage resources place.And in the present embodiment, be by before being called by hash algorithm at the UUID generated, its value is intercepted and captured, is saved in database.Call the API that Glusterfs provides again, with the UUID intercepted and captured for parameter, go to obtain the physical machine list at storage resources place thus complete the location of storage resources, after having located, by thermophoresis, computational resource having been moved on storage resources.Based on the interface exploitation API that the file system (as GFS, GoogleFileSystem, Google's file system) of other types provides, the location of storage resources also can be carried out.
Moving method and the system of concrete resource are as described below.
