Unable to configure public_network in Vagrant

When you create a virtual machine with vagrant on a KVM server, you cannot change the network settings.
The desired environment is to access guests created with vagrant from an external server.
I would like to make it public_network.

My environment is as follows.
Host (KVM server): CentOS Linux release 7.0.1406 (Core)
Guest:CentOS 7
vagrant:2.0.1 version
Network device (id must have vlanid)
Device Type State Connections
brens1f1.id bridge Connected bridge-brens1f1.id
virbr0bridge Connected virbr0
virbr1bridge Connected virbr1
ens1f0ethernet-connected ens1f0
ens1f1.id vlan Connected vlan-ens1f1.id

brctl show
bridge name bridge id STP enabled interfaces
brens1f1.id8000.a44c11deabe5no ens1f1.id
virbr0 8000.52540018f0be yes virbr0-nic
virbr18000.5254005c1399 yes virbr1-nic

# vi:set ft=ruby:   
Vagrant.configure("2") do | config |
  config.vm.box="centos/7"
  config.vm.network "public_network"
end

vagrant up --provider=libvirt

There was an error talking to Libvirt.The error message is down
below:

Call to virDomainCreateWithFlags failed: Unable to get index for interface eth0: No such device exists

Thank you for your cooperation.

In my environment,
config.vm.network "public_network",:dev=>'br0',:type=>'bridge'
It worked well when I had done so.I think it depends on the box.
