private network adapter 1 borks vm setup.

[gtmtech]

A note in the vagrant docs would be useful explaining not to configure adapter1 as a private_network otherwise it will bork the NAT adapter (adapter 1) which is essential for vagrant to setup the VM

I.e. this:

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "hashicorp/precise64"
config.vm.network "private_network", ip: "10.0.2.101", :adapter => 1
end

will never work, but this:

VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "hashicorp/precise64"
config.vm.network "private_network", ip: "10.0.2.101"
end

will work fine as it actually sets up a 2nd adapter.

Vagrant requires adapter 1 to be a NAT adapter. This is a limitation of Vagrant that we don't plan on fixing soon since it complicates the bootstrapping problem (how does one SSH reliably without it).
