Algorithm 1
The virtual machine migration algorithm.
| Input: , , . | | Output: . | | Procedure begin | | (1) for each in do | | (2) Use cloud model to predict future workloads for host , and push results into list | | (3) . Calculate the average of the predicted workloads and push result into list ; | | (4) if then | | (5) Add host ID into the list , select the VM with the largest average history | | (6) workload valueon the host , and add the VM into queue ; | | (7) end if | | (8) if then | | (9) Add host ID into list , and add all the virtual machines on the host into ; | | (10) end if | | (11) if then | | (12) Add host ID into list ; | | (13) end if | | (14) end for | | (15) for each in do | | (16) for each in do | | (17) if then | | (18) Migrate virtual machine to host , add VM information into list ; | | (19) end if | | (20) end for | | (21) end for | | (22) return ; | | end Procedure |
