VIRTUAL MACHINE REDEPLOYMENT

摘要

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.

1. A method, comprising:
identifying, by a computing device, a child virtual machine as being associated with a baseline virtual machine; and redeploying the baseline virtual machine to the child virtual machine, comprising:
creating a temporary directory on a datastore for the child virtual machine;responsive to the baseline virtual machine being disposed on a first controller and the child virtual machine being disposed on a second controller, performing a host-based copy mechanism to create a clone of a baseline virtual machine drive, used by the baseline virtual machine to store data, as a replacement virtual drive within the temporary directory; andreplacing an existing child virtual machine drive, used by the child virtual machine to store data, with the replacement virtual drive utilizing a single operation.
