发明名称 Computer system, device sharing method, and device sharing program
摘要 The disclosed is a computer system enabling a plurality of LPARs on a plurality of physical computers to share an SR-IOV device that requires an interface between a PF and a VF. In an environment where a PCI SR-IOV device is allocated to virtual machine monitors on a plurality of physical computers through an I/O switch, a PF is allocated to a first virtual machine monitor and a plurality of VFs is allocated to an LPAR on an optional virtual machine monitor. When a second virtual machine monitor detects an event that is generated from a VF to the PF, the second virtual machine monitor communicates the detected event to the first virtual machine monitor to which the PF is allocated, and allows the first virtual machine monitor to execute the PF event. Further, when the first virtual machine monitor detects an event that is generated from the PF to a VF, the first virtual machine monitor communicates the detected event to the second virtual machine monitor to which a target VF is allocated, and allows an LPAR on the second virtual machine monitor to execute the VF event.
