If I'm not mistaken, this is automatically assigned. However, you could define this in the domain XML using the target tag within the interface container, e.g. using the libvirt example <interface type='network'> <source network='default'/> <target dev='vnet7'/> <mac address="00:11:22:33:44:55"/> </interface> >From there, I suppose you could extract the information from the relevant xml with your script.
