The XiveFabric QOM interface acts as the PowerBUS interface between the interrupt controller and the system and should be implemented by the QEMU machine. On HW, the XIVE sub-engine is responsible for the communication with the other chip is the Common Queue (CQ) bridge unit. This interface offers a 'match_nvt' handler to perform the CAM line matching when looking for a XIVE Presenter with a dispatched NVT.
