Here is the full test :
--------------------------------------------------------------------------------
[root@mingwenv arnaud]# whoami
root
[root@mingwenv arnaud]# virsh
Bienvenue dans virsh, le terminal de virtualisation interactif.
Taper : « help » pour l'aide ou « help » avec la commande
« quit » pour quitter
virsh # iface-list

virsh # quit
[root@mingwenv arnaud]# exit
exit
[arnaud@mingwenv ~]$ whoami
arnaud
[arnaud@mingwenv ~]$ virsh
Bienvenue dans virsh, le terminal de virtualisation interactif.
Taper : « help » pour l'aide ou « help » avec la commande

virsh # iface-list
erreur :Failed to list active interfaces

--------------------------------------------------------------------------------
As you can see, at first, with root it works, not with my user account.

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

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?
