Opps, I meant to attach a copy of the ovirt-wui.xml for benefit of people
not familiar with virt-image / libvirt. The two files attached to this 
mail are the ovirt-wui.xml created by disk-creator for feeding to virt-image.
The second XML file is the libvirt XML generated from ovirt-wui.xml for the 
purposes of actually running the appliance in KVM

The core difference between the two is that the virt-image XML format
defines the *requirements* for running the VM, while the libvirt XML
format defines a specific *deployment* of the VM. The former is generic
to any HV, while the later is specific to the HV & host deployed under.

Dan
