I've attached a sample VM XML file that you can try.  It includes two 
network interfaces, and sets the cdrom device to present as a usb device 
on sda.  It doesn't look like it's currently working on the precise 
desktop image, so we may need to make some tweaks.  It does work on the 
alternate image, however.  This is also just me using a CD ISO and 
telling libvirt it's a USB disk, so maybe desktop will work with an 
actual USB disk.  In any case, both of these things can be handled by 
customizing the VM XML passed to the current code.  If we need more 
options for them, I can work on integrating those.
