Thanks, but problem still persists. I actually fat fingered entering it the first time The xmlfile really is: <?xml version="1.0"?> <interface type="network"> <mac address="52:54:00:5c:fe:a8"/> <source network="default"/> <target dev="vnet1"/> </interface> I ran xmllint and it just says no DTD specified, however this works perfectly if i use the attach-device command in virsh. I tired it both with and without the first line version=1.0 I try running it through python and boom, is there something else I'm missing? I can't find any documentation about the overall libvirt xml schema.
