Abstract
One or more techniques and/or systems are disclosed for redeploying a baseline VM (BVM) to one or more child VMs (CVMs) by merely cloning virtual drives of the BVM, instead of the entirety of the parent BVM. A temporary directory is created in a datastore that has the target CVMs that are targeted for virtual drive replacement (e.g., are to be “re-baselined”). One or more replacement virtual drives (RVDs) are created in the temporary directory, where the RVDs comprise a clone of a virtual drive of the source BVM. The one or more RVDs are moved from the temporary directory to a directory of the target CVMs, replacing existing virtual drives of the target CVMs so that the target CVMs are thus re-baselined to the state of the parent BVM.
