IRQ 6 may conflict with the irq of legacy floppy disk controllers. I fear that with only 2 bits set, only INTA and INTB will be set. However from piix_pci-dm.c, it appears we don't really use INTA/D mapping. Am I right ? Yes, you are right. Seems all pci device should get an irq 16 from the algorithm. But for KVM, we also need to use assigned irqs for INTA-INTD. But irq 6 shouldn't use for this purpose, it may confilicts with floppy disk controller.
