  generalize lgread_u32/lgwrite_u32.
  Example launcher handle guests not being ready for input
  Update example launcher for virtio
  Lguest support for Virtio
  Remove old lguest I/O infrrasructure.
  Remove old lguest bus and drivers.
  Virtio helper routines for a descriptor ringbuffer implementation
  Module autoprobing support for virtio drivers.
  Virtio console driver
  Block driver using virtio.
  Net driver using virtio
  Virtio interface

-          Paravirtualization is a way of running multiple instances of

           VMI provides a paravirtualized interface to the VMware ESX server
           (it could be used by other hypervisors in theory too, but is not
           at the moment), by linking the kernel to a GPL-ed ROM module
           provided by the hypervisor.
