A mechanism for patching a virtual image modifies 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. The mechanism downloads a boot medium and creates a temporary disk for a selected target virtual machine with corresponding deployment data The mechanism changes a master boot record of said temporary disk associated with the target virtual machine to boot next on the boot medium. The mechanism executes the patch logic to install the patch material in case the target virtual machine associated with the virtual image to be patched is booted. |
