Is there a special option maybe? > 1) what is the libvirt version? 2) are you using "virsh dumpxml --inactive"? The source should anyway be there when you do virsh dumpxml with or without --inactive, but the proper way to get the config of a domain that can be fed back into the domain is by using --inactive (otherwise you get the current status of the interface, which may have some differences). (I'm interested to learn the libvirt version because when I look at the virsh dumpxml of an <interface type='bridge'> on my system running current upstream libvirt, I *do* see the <source> element. Given the version you're running, I can possibly take a look at that vintage of source to see if there was a bug in that version)
