        !            17: Abstract: This is the final step towards PVH mode. This is relevant
        !            18: only for DomU.
        !            19: Xen is moving to this eventual dom0 pvh support model.
        !            20: This project depends on completion of pv-on-hvm.

        !            25: * PV only drivers.

        !            27: Implementation: 
        !            28: 
        !            29: Following on from the pv-on-hvm project, this project removes all
        !            30: remaining dependencies on native drivers. All drivers are PV
        !            31: only. Interrupt setup and handling is via the "event" mechanism.
        !            32: 
        !            33: Scope (Timelines):
        !            34: 
        !            35: This project has some uncertainty based on the change in the interrupt
        !            36: mechanism. Since the interrupt mechanism moves from apic + IDT based,
        !            37: to event based, there's room for debug/testing spillover.
        !            38: 
        !            39: Further, private APIs may need to be developed to parition the pv and
        !            40: native setup and management code for both mechanisms.
