Abstract: Disclosed herein are an apparatus and method for booting a virtual machine. The apparatus for booting a virtual machine includes: an access unit for accessing a virtual disk, corresponding to a virtual machine that exists in a virtualization area, using a trap generated by a trap generation unit, and for controlling the input and output of data stored in the virtual disk; an extraction unit for extracting data used for booting from the virtual disk; and a verification unit for extracting a trusted boot image from image storage and verifying the integrity of the data used for booting based on a result of comparing the trusted boot image with the data used for booting.

Abstract: A software update apparatus and method in a virtualized environment. The software update method performed by a software update apparatus in a virtualized environment includes monitoring an operation that is invoked when software is updated in a guest operating system area, creating a software profile by analyzing results of the monitoring, mounting a virtual disk image for a target virtual machine in a target directory in a virtual machine monitor area, and incorporating update information of at least one of a file and a registry that are specified in the software profile into the target directory in which the virtual disk image is mounted.
