If your libvirt is compiled without netcf then there will be no interface support for QEMU, Xen and so on. You'll also need to have a distro (e.g. Fedora) that supports netcf or is supported by netcf, because netcf handles the interface configuration files and those are in different locations of have other distro dependent differences.

That's strange. What error message do you get in cases where it doesn't work? Do you use the same libvirt version on all hosts that are involved? Matthias

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.
