Hi Conor,
you have to edit the domain XML file manually, there's no API yet.
Please see the example scripts in the examples directory of the cloned
repository. On the main page there is option to edit the domain XML
description but you have to have the domain stopped (not running) to
change the domain XML description.

Adding the new disk is done using the:

    <disk type='file' device='disk'>
      <driver name='qemu' type='raw'/>
      <source file='/home/mig/images/kvm/winxp.img'/>
      <target dev='hda' bus='ide'/>
    </disk>

definition where /driver/@type is the type of the driver to be used for
the image - raw is the standard image but you can also put qcow2 image
there if supported by your hypervisor/emulator (e.g. QEMU). By target
you can define the device presented to the guest and bus type (i.e. IDE
or SCSI) and after this you can start up the guest with the
configuration mentioned there. You can pass the address element there as
well but you don't have to since it's generated automatically when omited.
