Abstract

A method includes receiving a request to perform a virtual machine (VM) copy operation that copies the VM from a source to a target location. The VM includes a hierarchy of storage components in levels. The operation includes a first and second sub-operation for each storage component at a lowest level in the hierarchy. The method includes transmitting a VM copy instruction, identifying a weight assigned to each storage component in the hierarchy, the weight based on a property of a storage component. The weight of the storage component at the lowest level is divided into first and second weight portions. The method also includes receiving a completion percentage for the sub-operations, determining an overall completion progress percentage of the operation using the sub-operation completion percentages and the weight portions for each storage component at the lowest level, and transmitting the overall completion percentage.
