    libxl/pvh: force PVH guests to use the xenstore shutdown
    
    PVH guests are all required to support the xenstore-based shutdown
    signalling, since there is no other way for a PVH guest to be
    requested to shut down.
    
    For HVM guests we check whether the guest has installed a PV-on-HVM
    interrupt callback; that does not make sense for PVH guests.
    
    So for PVH guests, take the PV path: assume that all PVH guests have
    suitable xenstore drivers.
