Couldn't add "network interface" in virt-manager

I'm using arch 64bits linux.

Reproduce steps
1. start libvirtd
2. launch virt-manager
3. From menu, "Edit" -> "connection details" -> "network interface"

There is no interface showing in the left side.
And if press "+" button to add an interface, I get following error:

Error creating interface: 'Could not define interface: internal error could not get interface XML description: unspecified error - aug_save failed'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/createinterface.py", line 1135, in do_install
    self.interface.install(meter, create=activate)
  File "/usr/lib/python2.7/site-packages/virtinst/Interface.py", line 242, in install
    raise RuntimeError(_("Could not define interface: %s" % str(e)))
RuntimeError: Could not define interface: internal error could not get interface XML description: unspecified error - aug_save failed

I'm using netcfg to configure my network.

#   - set to 'last' to restore the profiles running at the last shutdown
#   - set to 'menu' to present a menu (requires the dialog package)
# Network profiles are found in /etc/network.d

#AUTO_PROFILES=("profile1" "profile2")

Other network functions work well.
