When consolidation is performed, data from the delta disks are merged with the main disk and unnecessary files on the storage are removed. Wait for the “ Consolidate virtual machine disk files” task to complete. During consolidation, VM performance may degrade. The consolidation process can take a long time depending on the size of the VM, the number of snapshots, and the current host/datastore load. Then vCenter will consolidate disks and clear the logs. Are you sure you want to continue?Ĭonfirm that you want to delete the redundant logs. This operation consolidates all redundant redo logs on your virtual machine. I am basically searching for the algorithms not the physical optimizations and I also know that many commercial organizations have provided these solution but I just wanted to know more the underlying algorithms.A window with the following request appears: Confirm Consolidate Would anyone please clarify the solution or suggest any new approach/resources for better
I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations.īrute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by first Fit decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets.
Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. A PM with no VMs is shut down to save power. Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram r i. We have N physical machines(PMs) each with ram R i, cpu C i and a set of currently scheduled VMs each with ram requirement r i and c i respectively
