Apparently add_bond_info() in netcf is failing to get the slave interface names from the netlink cache. I'm fairly certain that worked at one time (since the code exists, and I surely tested it prior to push).
Actually I missed the fact that the bond interface in the example is inactive. This is *really* the same thing as Bug 878394 (filed against RHEL7), a libvirt bug, which is fixed by the following upstream commit:
commit 7284c499e54e538fd0ab35a1f09e358f06fc23b0

interface: dump inactive xml when interface isn't active
I just checked and that commit was pulled into the v1.1.3-maint branch prior to 1.1.3.5, so it is already in the current libvirt in F20. It *isn't* in F19 yet (and will require commit 50f5468c960f4fe491399d5a495426e6cb6b41f1 and some conflict resolution if that's desired)
