[0004]Current research is mostly focused on the dynamic migration method during the migration process, such as VMware and Xen have already realized the dynamic migration of virtual machines, but these migration processes require manual According to the state of the virtual machine, it is up to the management personnel to judge and operate, and choose whether to migrate according to the state of the virtual machine, and select the migration destination. For the automatic judgment of the state of the virtual machine before migration, whether it needs to be migrated, and the relocation after migration Judgment, judging whether the migration has achieved the purpose of the migration, there is no relevant research

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] One of embodiment:
[0023] like figure 1 As shown, the overall structure of the dynamic self-migration cloud service includes detection module SA, migration authority MA, post-migration detection authority AMD, idle queue {leisure}, intermediate queue {medium} and busy queue {busy}. SA is responsible for monitoring each physical machine, recording the status of each physical machine, and classifying the machines according to the CPU, I / O, and memory usage status of the machine. The usage rate of CPU, I / O, and memory exceeds the threshold Fmax , it will be assigned to the {busy} group; if the usage rate of CPU, I / O, and memory is less than Fmin, it will be assigned to the {leisure} queue, and the others will be assigned to the {medium} queue. When the migration algorithm is satisfied, the migration authority MA is notified. MA is resp...

The invention relates to a dynamic self-migrating cloud service method, which is characterized in that cloud service can automatically judge a status of a virtual machine, the virtual machine is dynamically migrated when satisfying the migration requirement, the service usability and reliability can be improved while the service continuity is ensured, and the resource can be saved. The dynamic self-migrating cloud service method has advantages that in the cloud service the switch and the working load of the virtual machine can be automatically and dynamically adjusted according to the moment application quantity, when the application quantity is large, the virtual machine can be automatically migrated onto a plurality of physical machines so as to ensure the usability of the service; and when the application quantity is reduced, the service on a plurality of virtual machines on multiple physical machines can be dynamically migrated onto the virtual machine of one physical machine, and other physical machines are closed, so that the effect for saving the resource can be realized.
Description
technical field [0001] The invention relates to the technical field of cloud computing security, in particular to a method for automatically performing dynamic migration of a virtual machine according to the state of the virtual machine in cloud computing. Background technique [0002] Virtual technology is an important technology to realize cloud computing. In order to ensure the high availability and reliability of cloud services, the migration of virtual machines has become a hot research topic. There are currently three methods for virtual machine migration: Stop-and-copy (S-C), Demand-migration (D-M) and Iterative precopy (I-P). Among them, Stop-and-copy (S-C) firstly stops the virtual machine to be migrated before the migration, then transfers it, and restores it after the migration is completed. Demand migration (Demand-migration (D-M)), during demand migration, first enters a very short stop-and-copy stage, stops the original virtual machine, first transfers import...
