title: vagrant 1.0.3 not creating device for host only network debian 6
body: <p>I have a hostonly network created with the following line in my Vagrantfile</p>
  
  <pre><code>config.vm.network :hostonly, "10.1.1.15"
  </code></pre>
  
  <p>I can see that it sets up the /etc/network/interfaces file</p>
  
  <pre><code>#VAGRANT-BEGIN
  # The contents below are automatically generated by Vagrant. Do not modify.
  auto eth1
  iface eth1 inet static
        address 10.1.1.15
        netmask 255.255.255.0
  #VAGRANT-END
  </code></pre>
  
  <p>However, when I run ifconfig I only see an eth0 and a lo device. Why is vagrant not setting up a device for eth1? What is the solution to fix this?</p>
