+.Sh DESCRIPTION
+.Nm
+defines an interface for efficient, standard and extensible I/O between the
+hypervisor and the virtual machine.
+The
+.Nm
+device driver represents an emulated device that the hypervisor makes
+available to the virtual machine.
+.Pp
+.Nm
+driver itself provides the core infrastructure to communicate
+with the hypervisor (called virtqueues) and supports the following devices:
