A SBSP writes a log into a spad in a log processor and the writing of the log from the spad to a serial port is performed by the log processor. When initialization of a main memory has been completed, the log processor temporarily writes the data read from the spad into a logmem and then clears the spad. Furthermore, when an output of the log performed by the log processor has been completed, the SBSP adds, in cooperation with the BIOS and the OS, the log processor and the logmem as the resources.

When an access from a virtual machine to a VGA is detected, a table managing identification information of a bridge on each path from a CPU to each VGA and passage setting information indicating whether or not to permit the passage of each path is referred to, and table information and a state of each bridge are set such that the passage of the path from the CPU to an SVGA to be accessed by the corresponding virtual machine is permitted, and the access is executed. Therefore, collision of I/O addresses can be avoided while maintaining the state of connecting a plurality of VGAs with fixed I/O addresses to a plurality of virtual machines.
