Hey Tom, sorry for the delayed response.

libvirt or netcf is choking on something here. If you're still seeing the
issue, try 'sudo virsh iface-dumpxml' for every name in 'sudo virsh
iface-list
--all': one of them should error like that log message.

Then take the associated ifcfg file in /etc/sysconfig/network/ and attach to a
libvirt bug report and we can follow up there.

Thanks,
Cole
