PROBLEM TO BE SOLVED: To emulate VF in an SR-IOV compatible device.SOLUTION: In a virtual machine system in which a guest OS operates on a virtual machine by a virtualization mechanism, an SR-IOV compatible device comprises Physical Function (PF) and Virtual Function (VF). The virtualization mechanism monitors the PF, sets a first mode when a link state of the PF of a monitoring target is in a link-up state, sets a second mode when in a link-down state, and emulates the link-down state of the VF by inhibiting the SR-IOV compatible device related to the VF from responding to a command related to the VF from the guest OS when the second mode is set. |
