[libvirt] netcf error message...

folowing the instructions in netcf I'm trying to run some basic interface configuration via libvirt patched with the netcf patches I get error messages - but the interface(eth1) seem to be managed correctly - do I have an aug(what is that?) problem? virsh # iface-define /root/libvirt_working/eth1.xml error: Failed to define interface from /root/libvirt_working/eth1.xml error: internal error could not get interface XML description (netcf: unspecified error - aug_save failed) virsh # iface-list Name State MAC Address -------------------------------------------- eth0 active 00:18:fe:28:7d:82 lo active 00:00:00:00:00:00 virsh # iface-start eth1 Interface eth1 started virsh # iface-list Name State MAC Address -------------------------------------------- eth0 active 00:18:fe:28:7d:82 eth1 active 00:18:fe:28:7d:83 lo active 00:00:00:00:00:00
