Make use of the new vector notifier to track changes of the MSI-X configuration of virtio PCI devices. On enabling events, we establish the required virtual IRQ to MSI-X message route and link the signaling eventfd file descriptor to this vIRQ line. That way, vhost-generated interrupts can be directly delivered to an in-kernel MSI-X consumer like the x86 APIC.
