Abstract: A method for reconfiguring a snapshot of a virtual machine (VM) is disclosed. A VM may be deployed on a hypervisor (204) running on a computer (202). The method comprises provisioning of a VM (206), installing and configuring an operating system (210) and a base program (212). A snapshot (230) of the virtual machine is taken, including both the operating system and the base program along with configuration data defining the configuration of the virtual machine, the operating system and base application in a metadata descriptor (232). The content of the metadata descriptor may be modified, and it may be reverted back to the snapshot using the modified content of the metadata descriptor such that the snapshot of the virtual machine with the operating system and the base program is reconfigured upon deployment of the snapshot including the operating system and the base program. A snapshot may include a second program (214) and associated configuration data. A user interface may be supplied to modify the metadata (Fig 4, 408).
