+ For character device with type <code>unix</code> or <code>tcp</code>
+ the <code>source</code> has an optional element <code>reconnect</code>
+ which configures reconnect timeout if the connection is lost.
+ There are two attributes, <code>enabled</code> where possible
+ values are <code>yes</code> and <code>no</code> and <code>timeout</code>
+ which is in seconds. The <code>reconnect</code> attribute is valid only
+ for <code>connect</code> mode.
+ <span class="since">Since 3.7.0 (QEMU driver only)</span>.
