Vagrantで複数のNICを追加する方法

備忘

c.vm.network :private_network, "ip" を複数回書くとその分だけNICが追加されるようだ

Vagrant.configure(2) do |config|
  config.vm.define :hoge do |c|
    c.vm.box      = "puppetlabs/centos-7.0-64-puppet"
    c.vm.hostname = "receiver"

    c.vm.network :private_network, "192.168.0.11"
    c.vm.network :private_network, "192.168.69.11"
  end
end
