The present invention generally provides embodiments relative to a method for PCI interrupt routing in a logically partitioned guest operating system. The method, which may be embodied upon a computer readable medium and executed by a processor, may include the steps of locating primary PCI buses, initializing IRQ tables, locating hardware interrupt sources, and activating an interrupt handling process. Embodiments of the present invention include the capability to mask and unmask function interrupts for each device associated with the guest operating system, wherein the process of masking and unmasking function interrupts may include calling a hypervisor to associate an OS IRQ number with a slot.
