When you run virsh locally as non-root, it connects to qemu://session, 
which doesn't have root privileges, and the iface-* commands won't work 
(because netcf requires root to run). If you run virsh as root, you will 
be connected to qemu://system, which has root, and iface-* will work.

The failure to work when connecting to a remote libvirtd is puzzling,
