NAME
     virtio -- Para-virtualized I/O in a virtual machine

SYNOPSIS
     virtio* at pci? dev ? function ?

DESCRIPTION
     virtio defines an interface for efficient, standard and extensible I/O between the hypervi-
     sor and the virtual machine.  The virtio device driver represents an emulated PCI device
     that the hypervisor makes available to the virtual machine.

     virtio driver itself provides the core infrastructure to communicate with the hypervisor
     (called virtqueues) and supports the following devices:

     ld(4)  A Disk device.

     vioif(4)
	    An Ethernet device.

     viomb(4)
	    A pseudo-device to release memory back to the hypervisor.
