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.
