Abstract: Techniques are described for reducing capacity fragmentation by using an Automatic Defragmentation Service (ADS). More particularly, hypervisors (HVs) that are candidates to defragment are identified, an HV to defragment is selected, and one or more VM instances are migrated from the selected HV to a different HV. According to certain implementations, instead of migrating a VM to a new HV, the VM is live migrated to an existing HV.
