Abstract
Each of a plurality of virtual machines (VMs) is stored in a halted form in a library for retrieval from the library and re-starting on a host. Each re-started VM includes a plurality of software constructs, each of which is at least potentially non-current and requires a software update. To update a non-current VM, such VM is retrieved and re-started on a maintenance host, and each non-current software construct is allowed to be updated by obtaining the required software update from a corresponding update source as a patch. Alternatively, the VM is mounted to a computing device, constituent components of the mounted VM are examined to determine whether each software construct thereof is current, and each non-current software construct is updated by obtaining the required software update from the corresponding update source as a patch and applying same to the mounted VM.
