Having fun with docbook

For some reason you need to apply the dbfo at different level to apply properties to an element:

<example>
<?dbfo pgwide="1"?> <!-- example level -->
<title>
Full example
</title>
<programlisting language="csharp">
<?dbfo keep-together="auto" ?> <!-- at programlisting level -->
<xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="MyCode.cs" parse="text"/></programlisting>
</example>

virt-manager: Can't choose ISO-image (remote connection, ssh)

While reading: https://bugs.debian.org/512253

I discovered that one need to restart virt-manager to get it to scan for new iso on the remote ssh.

Eg:

$ virt-manager
^C
$ scp *.iso remote:/var/lib/libvirt/images/
$ virt-manager
-> Browse -> "Locate ISO media volume"
