So I withdraw this patch and rework the controller type handling to
use the <controller> element.
There seems to be no documentation about the <controller> element on
the libvirt website, or do I miss something?
That is correct :-(
As an example, if you had two SCSI controllers & one IDE controller, you'd
get XML like
<controller type='scsi' index='0'/>
<controller type='scsi' index='1'/>
<controller type='ide' index='0'/>
Inside the <disk> element, you link to a controller based on its index,
using the <address> element type. If you omit '<address>' it is
calculated
from the target dev name, eg sdj corresponds to controller 1, unit 2. The
automatic calculation assumes only one bus per controller.
<disk type='file' device='disk'>
<source file='/home/berrange/output.img'/>
<target dev='sdj' bus='scsi'/>
<address type='drive' controller='1' bus='0'
unit='2'/>
</disk>

Daniel
