Information processing apparatus reading data using host physcal address and guest physical address and computer-readable recording medium recording control program reading data using host physical address and guest physical address

Abstract

An information processing apparatus coupled to a storage device via a network includes a processor configured to: acquire a host physical address over a physical storage region in which information regarding an access to the storage device from a guest OS is stored from a first packet stored in the physical storage region storing a packet obtained by encapsulating the information regarding the access; convert the acquired host physical address into a guest physical address recognized by the guest OS; create a data structure of a block device; store the guest physical address in a data address region of the data structure; specify the host physical address corresponding to the guest physical address while referring to the memory when reading from the data address region is detected; read data from the specified host physical address over the physical storage region; and transfer the read data to the guest OS.
