Abstract

An aspect of the invention is a storage control apparatus, comprising a plurality of processors, a memory, an I/O device coupled to a storage device, a virtualization module that allocates a first processor to a first guest and a second processor to a second guest from among the plurality of processors, and an interrupt control module that receives an interrupt from the I/O device and transmits the interrupt to any one of the plurality of processors, wherein the virtualization module comprises, a state detection module that detects at least one of a state of the first guest and a state of the first processor, and an interrupt delivery destination control module that switches the interrupt with respect to the first processor to the second processor when at least one of the state of the first guest and the state of the first processor becomes a predetermined state.
