Hi,
Yes I know that, and I use the fedora 12 distro, with netcf support and libvirt rpm are compiled with netcf support. That's why it works when I am root, but only when I am root

Hi,
I'm trying to list physical interface of a remote tcp host via the C API and it fails. I have tried to use virsh iface-list in remote TCP connection and it fails also. I have trying on the libvirt host with my normal account and it fails also, but when I connect under root account on the libvirt host, iface-list works. Any clue ?
The current interface driver used in combination with libvirtd is nefcf [1] based. 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.

Ah, sorry I misread the part where you say it works locally as root. 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?
