Abstract: An encryption setting application method may include acquiring a virtual machine image including a script that describes a hooking operation of a booting process and an encryption setting operation; hooking the booting process based on the hooking operation after booting of a virtual machine starts; applying an encryption setting to the virtual machine based on the encryption setting operation; and restarting the booting process of the virtual machine.

Abstract: A remote access method include acquiring a virtual machine image including a remote access function to be temporarily executed during booting of a virtual machine; generating the virtual machine using the virtual machine image; executing the remote access function included in the virtual machine image after booting of the virtual machine starts; and, in response to occurrence of an error during booting of the virtual machine, guiding an owner of the virtual machine through an access scheme to the remote access function of the virtual machine in which booting is pending based on the remote access function.
