Abstract
One or more techniques and/or systems are disclosed that provide for cloning VMs, where different parts of the same VM are cloned separately. A temporary repository directory in a datastore of a storage controller is populated with a copy of one or more source virtual drive image files, which were generated from a source virtual machine (SVM) that is being cloned. A diskless virtual machine (DVM) is created in a destination container using configurations from the SVM. The copy of the one or more source virtual drive image files is cloned a desired number of times corresponding to a desired number of virtual machine clones. The DVM is cloned a desired number of times corresponding to a desired number of virtual machine clones. The DVM clones are combined with the source virtual drive image file clones in the destination container.
