  • Patent number: 10162657
    Abstract: An information processing device includes a processor that executes a process. The process includes: identifying a cause of a shift from non-privileged mode to privileged mode that has occurred in processing by a guest program in an upper level virtual machine in a nested virtualization environment in which a first level virtual machine monitor operates in privileged mode, and an upper level virtual machine monitor and the guest program operate in non-privileged mode; and when the identified cause is setting or updating a virtual translation table employed in a virtual translation mechanism provided to the guest program by virtualizing an address translation mechanism for hardware that uses a set translation table to translate addresses of DMA by an input/output device assigned to the upper level virtual machine, setting the translation table employed by the translation mechanism based on a correspondence relationship between guest memory space and host memory space.
