—This paper presents a modified best fit decreasing
algorithm (MBFD algorithm) for virtual machines dynamic
migration scheduling model. The model uses the bin packing
problem classical approximation algorithm idea, designs a new
algorithm to deal with virtual machines dynamic migrating
scheduling. It finds out load hot-spot hosts in the cloud platform
by executing the selection algorithm program. Then the
resource loads of virtual machines in hot-spot hosts are sorted
in descending order. As for non-hot-spot hosts, their resource
loads are sorted in ascending order. By traversing the
non-hot-spot hosts queue, it can find the most appropriate host
to act as the migration target host.
