 \section{Virtqueues}\label{sec:Basic Facilities of a Virtio Device /
Virtqueues}

 The mechanism for bulk data transport on virtio devices is
-pretentiously called a virtqueue. Each device can have zero or more
-virtqueues: for example, the simplest network device has one for
-transmit and one for receive.  Each queue has a 16-bit queue size
-parameter, which sets the number of entries and implies the total size
-of the queue.
