2 arguments (1 given)
They are because, libvirt has not a default value for flags. We should use: conn.interfaceDefineXML(br_xml, 0) and vlan_tagged_br.create(0)
Ramon, could you include those fix in this patch?
You said that i need to change the remove_vg function too. What function that i have to pass the 0 flag? def _remove_vlan_tagged_bridge(self, network): try: bridge = network.bridgeName() except libvirt.libvirtError: pass else: if bridge.startswith('kimchi-'): conn = self.conn.get() iface = conn.interfaceLookupByName(bridge) if iface.isActive(): iface.destroy() iface.undefine() iface.destroy(0) and iface.undefine(0)?

Python binding for libvirt does not support conn.changeBegin() and conn.commit(). To make the change safe, this procedure was changed to a internal framework: RollbackContext.
