In local APIC passthrough case, when devices triggered a INTx interrupt, this interrupt would be delivered to vCPU directly. For this case, need to set the virtual vector in the 'Interrupt Vector' field of physical IOxAPIC I/O REDIRECTION TABLE REGISTER (bits 7:0) and 'Vector' field of vt-d Interrupt Remapping Table Entry (IRTE) for Remapped Interrupts. Assumption: (a) IOAPIC pins won't be shared between LAPIC PT guest and other guests; (b) The guest would not trigger this IRQ before it switched to x2 APIC mode.
