Abstract: 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.

Abstract: 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.

Abstract: An information processing device creates a management table of bridge addresses by allocating the bridge addresses to a plurality of bridges, respectively, and, when detecting one access to one device of a plurality of devices, refers to the management table, performs, based on the management table referred to, cancelling allocation of a bridge address of the bridge addresses and reallocating the bridge address to one or more of the plurality of bridges to enable execution of the one access, and updates the management table in regard to the bridge address cancelled and reallocated. Consequently, the information processing device can simultaneously use bridges the number of which exceeds a predetermined number even when the bridges the number of which exceeds the predetermined number are provided in the information processing device and therefore bridge addresses run out.

Abstract: Equipping a first computer with an interface card having an access function of accessing a storage and a communication function of performing a communication via a network. Connecting the interface card equipped in the first computer and a second computer by the network. Causing the interface card to process target data received from the second computer and to cause the target data to be saved in a first storage, which is a storage connected to the interface card, when the second computer transmits the target data to be saved to the interface card.

Abstract: A virtual machine system includes a first storage unit, a second storage unit, and a processor. The first storage unit includes a storage area allocated for a first virtual machine to operate. The second storage unit stores information stored in the first storage unit. The processor executes a process including detecting a failure of a first virtual machine, generating a second virtual machine when a failure of the first virtual machine is detected and making the second virtual machine perform storing information stored in the first storage unit into the second storage unit, and deleting the second virtual machine when the storing by the second virtual machine is completed.
