The Œethernet¹ interface type assumes that you have an existing tap device. Did you check if the tap device that it is complaining against actually exists in the host?
Yes, but ethernet device type does not always means that device already exists. Before this patch a have devices automatic created with libvirt/qemu for me.
The patch didn’t do anything to add/delete tap devices. Please see the following links where similar issue has been discussed. http://wiki.libvirt.org/page/Guest_won%27t_start_-_warning:_could_not_open_ /dev/net/tun_%28%27generic_ethernet%27_interface%29 https://answers.launchpad.net/neutron/+question/179967 Anirban
