Странные сетевые проблемы с Бродягой, VirtualBox, полем Ansible и Ubuntu Server

Мы используем Vagrant и Ansible для настройки машины VirtualBox.

Это работало отлично, но недавно мы начали встречаться с некоторыми странными сетевыми проблемами с задачами, которые требуют доступа к Интернету, как: apt-get update, composer update, gem install и т.д. Эти проблемы время от времени появляются, и они нестабильны. Иногда это не может соединиться с некоторым именем сервера, или доменное имя не решает.

Интересно, когда я соединяюсь с самим полем через SSH (vagrant ssh) и дайте такие команды вручную, как sudo apt-get update; sudo apt-get dist-upgrade - это хорошо работает все время.

Вот демонстрационная ошибка с NPM:

Версии программного обеспечения:

• ansible 1.6.6
• Бродяга 1.6.3
• VirtualBox 4.3.14

Мы используем следующее поле:

http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.box

Хостом ОС является Ubuntu 14.04.

Мы встречаемся с такими проблемами с различными компьютерами в абсолютно различных сетях (различные города).

Какова может быть причина этого? Как мы отлаживаем его и фиксируем его?

Обновление № 1

Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

# "2" is an API version here.
Vagrant.configure("2") do |config|

  config.vm.box = "trusty32"
  config.vm.box_url = "http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-i386-vagrant-disk1.box"

  config.vm.hostname = "wa.local"
  config.vm.network "private_network", ip: "192.168.2.2"

  # Using NFS for now, cause native sharing is broken
  config.vm.synced_folder ".", "/vagrant", nfs: true

  # Provisioning
  config.vm.provision "ansible" do |ansible|
    ansible.host_key_checking = false
    ansible.inventory_path = "ansible/inventory.ini"
    ansible.playbook = "ansible/vagrant.yml"
    ansible.limit = "all"
  end

  # Provider Configuration: VirtualBox
  config.vm.provider :virtualbox do |vb|
    # Setting RAM to 1 GB
    vb.memory = 1024
    vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
  end

end

Обновление № 2

Проблемы не стало на данный момент. Я все еще не знаю, почему это произошло во-первых. Возможно, строка vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"] то, что я недавно добавил к Vagrantfile, помогло.

Спасибо за все предложения!
