METHOD AND SYSTEM FOR PATCHING A VIRTUAL IMAGE

摘要

An improved method for patching a virtual image comprises the steps: Modifying a selected dormant virtual image to be patched by injecting a corresponding patch logic, and patch material to be applied on next boot during an off-line preparation phase; downloading a boot medium (42) and creating a temporary disk (52) for a selected target virtual machine (50) with corresponding deployment data; changing a master boot record of said temporary disk (52) associated with said target virtual machine (50) to boot next on said boot medium (42); and executing said patch logic to install said patch material in case said target virtual machine (50) associated with said virtual image to be patched is booted.
