Sure. As I said - it is allocated at domain start up phase. Because
that's when we know what's the next free device (or name that we can use
for the device). If you start the domain, with your configuration
libvirt will create vnetX and plug it into br1. Essentially, target
device is runtime information, thus not present in config XML.
