ABSTRACT:
An apparatus for collecting control data of a virtual machine in order to collect control data of a control portion (CP) of a virtual machine as well as control data of an operating system (OS) controlled by the CP, and a method thereof to simultaneously collect the CP data and the OS data. The function of the OS that uses the data which is to be collected is suppressed at the time when the data are to be collected, and the OS requests the CP to transfer the CP data. In response to the data transfer request, the function of the CP using the data that are to be collected is suppressed, and then the CP data are transferred to the buffer of the OS. The function of the CP that had been suppressed is then resumed. The OS simultaneously edits and outputs the data transferred from the CP and the OS data that exist on the OS, and then the function of the OS that had been suppressed is resumed.
