Need ability to specify multiple vm.network settings in vagrant_options

[steversmith]

We have a requirement to specify multiple vm.network settings in our vagrant_options. For example, setting a private network IP address, as well as setting a forwarded port.

Setting up an options hash with multiple vm.network settings will not work, since the resulting hash will only include the last setting:

options = {
  vagrant_options: {
    'vm.box' => 'redhat',
    'vm.network' => ':private_network, {ip: "192.168.33.34"}',
    'vm.network' => ':forwarded_port, guest: 27017, host: 27117'
  }
}

machine 'somemachine' do
  machine_options options
end

Produces the following vagrant file, which does not include both settings (e.g. the private_network setting):

Vagrant.configure('2') do |outer_config|
  outer_config.vm.define "somemachine" do |config|
    config.vm.box = "redhat"
    config.vm.network(:forwarded_port, guest: 27017, host: 27117)
    config.vm.hostname = "somemachine"
  end
end

Using a multi-valued setting for the vm.network setting also does not work since Vagrant does not handle a setting with multiple values (e.g. an array).

options = {
  vagrant_options: {
    'vm.box' => 'redhat',
    'vm.network' => [
      ':private_network, {ip: "192.168.33.34"}',
      ':forwarded_port, guest: 27017, host: 27117'
    ]
  }
}

machine 'somemachine' do
  machine_options options
end

Produces the following vagrant file, which causes vagrant to fail:

Vagrant.configure('2') do |outer_config|
  outer_config.vm.define "somemachine" do |config|
    config.vm.box = "redhat"
    config.vm.network([":private_network, {ip: \"192.168.33.34\"}", ":forwarded_port, guest: 27017, host: 27117"])
    config.vm.hostname = "somemachine"
  end
end

The vagrant failure:

    RuntimeError

    vagrant up somemachine --provider virtualbox failed!
