There's a slight issue in that if an interrupt happens while a vcpu

We can check pic output after LVT0.ExtInt is configured.
Right.
btw, I think virtual wire refers to:
pic -> ioapic(ExtInt) -> (apic bus) -> lapic
(virtual wire since the interrupt is passed over the apic bus, not a
real wire)
while our configuration is
pic -> lint0 -> lapic lvt0 (ExtInt)
I saw both referred as virtual wire, may be erroneous.
How is the mode where lapic is disabled and pic interrupts are delivered
directly to cpu is called?
I'm just guessing based on the name, no idea really.
