Abstract: A machine system includes a physical machine, a memory pool, and a memory pool management machine. The memory pool management machine manages, with respect to a memory region of the memory pool, an allocated region, a cleared region, and an uncleared region. When generating a virtual machine, a hypervisor in the physical machine sends a memory allocation request to the memory pool management machine. When a response, to the request, received from the memory pool management machine includes an address range belonging to the uncleared region, the hypervisor clears the memory region of the address range belonging to the uncleared region and then generates the virtual machine.

Abstract: A hypervisor that allocates the computer resource of a physical computer to one or more logical partitions allocates the computer resource to be allocated to the logical partitions to the logical partitions; generates, as address conversion information, the relationship between a guest physical address and a host physical address with respect to a memory of the computer resource; enables a first address conversion portion of a processor using the address conversion information; disables the first address conversion portion after the starting of a guest OS is completed; and causes an application to be executed.

Abstract: In a method of controlling a communication path among a plurality of virtual machines operating in one or more physical machines each of which includes one or more CPUs, memories, and I/O devices, allocating a virtual buffer serving as an alias of an actual buffer of a first virtual machine to a communication port that serves as a destination to which a communication path is changed from the first virtual machine and a second virtual machine directly or indirectly communicates with using a communication path change instruction as a trigger. Then, performing memory address translation on a region of the memory referred to by the virtual buffer, and generating the communication path between the first virtual machine and the second virtual machine by associating a region of the memory referred to by the first virtual machine and a region of the memory referred to by the second virtual machine.
