ABSTRACT:
An OS control method for controlling an operating system (OS) running in a computer system on which a plurality of OSs run and which includes an instruction processor, a control program for controlling running of a plurality of OSs, a main storage, an external storage device, and an address translation circuit. In the course of processing performed by the instruction processor, predetermined operation of the instruction processor is monitored to output trace data affixed with an address conforming to the running OS in accordance with predetermined conditions for the predetermined operation. Address for the running OS is translated into a real address on the main storage. A debugging assist unit outputs trace data to one of plural storing areas of the main storage corresponding to the running OS at the translated real address. In the state in which the storing area containing the real address on the main storage resulting from transaltion of the address for the running OS is paged out, the trace data for the running OS is outputted to a host trace area.
