The driver typically does this as follows, for each virtqueue a device has:

\begin{enumerate}
-\item Write the virtqueue index (first queue is 0) to \field{queue_select}.
+\item Write the virtqueue index to \field{queue_select}.

\item Read the virtqueue size from \field{queue_size}. This controls how big the virtqueue is
(see \ref{sec:Basic Facilities of a Virtio Device / Virtqueues}~\nameref{sec:Basic Facilities of a Virtio Device / Virtqueues}). If this field is 0, the virtqueue does not exist.
