Patent ID: 8561056

Claim:
A computer-implemented method comprising: extracting, during a current installation of a guest operating system on a virtual machine hosted by a computer system, a region of an image according to a stored definition of the region; computing, by the computer system, a checksum of the region of the image that represents a user input request during the current installation of the guest operating system; obtaining a stored checksum corresponding to the computed checksum, the stored checksum being obtained using manual installation data recorded during a manual installation of the guest operating system, the manual installation data comprising user inputs pertaining to respective user input requests, the manual installation data further comprising stored checksums associated with the respective user input requests; comparing, by the computer system, the computed checksum with the stored checksum; and when the computed checksum matches the stored checksum, utilizing, by the computer system, a corresponding user input, recorded during the manual installation of the guest operating system, as a response to the user input request during the current installation of the guest operating system.
