</summary>
<description>
The <code>vgaconf</code> attribute was added to <code>video</code>'s
<code>driver</code> element. Possible values are: <code>on</code>,
<code>off</code>, and <code>io</code>. It controlls the way how
bhyve exposes video devices to its guests; various guest OSes might
require different settings to boot properly.
