Abstract: In one set of embodiments, during an initial pre-copying phase, copies of the virtual disks of a VM or VM template can be distributed across one or more datastores, prior to the start of any cloning. This effectively seeds each datastore with a disk pool comprising a certain number of copies of the VM/VM template's virtual disks. Then, at the time of receiving a user request to create k clones from the VM/VM template, up to k copies of the VM/VM template's virtual disks that already reside in the disk pools of one or more target datastores can be moved from those disk pools to the clones' home folders on the target datastores, thereby reducing or eliminating the need to create brand new copies of the virtual disks on demand.
