network.ipv4 does not work for debian squeeze

[paneq]

This is related to #31 which however is a very big ticket so I wanted to create a smaller one. Feel free to close it if you already know about this.

• According to my tests this does not work yet:

 config.vm.network :private_network, ip: "10.0.3.137"

• This works for me on Ubuntu Quantal but not for Debian Squeeze container:

config.vm.provider :lxc do |lxc|
  lxc.customize "network.ipv4", "10.0.3.137"
end

Host is Ubuntu 12.04.

@paneq that is pretty weird, I'll try to reproduce it on a VBox VM and will get back to you. tks for reporting

Here is my workaround that I put into Vagrantfile. Definitely not a perfect solution but seems to be working with Debian Squeeze:

  require 'vagrant-lxc/provider'
  require 'vagrant-lxc/action'
  module Vagrant
    module LXC
      class Provider
        def ssh_info
          # If the Container is not created then we cannot possibly SSH into it, so
          # we return nil.
          return nil if state == :not_created

          ip = @machine.config.vm.networks.map do |type, options|
            type == :private_network && options[:ip] || nil
          end.compact.first || @driver.assigned_ip
          {
            :host => ip,
            :port => @machine.config.ssh.guest_port
          }
        end
      end
      module Action
        class << self
          alias_method :original_action_boot, :action_boot
          def action_boot
            action_builder = original_action_boot
            action_builder.insert_before(Vagrant::LXC::Action::Boot, Vagrant::Action::Builder.new.tap{|b| b.use Vagrant::LXC::Action::Magic } )
            action_builder
          end
        end
        class Magic
          def initialize(app, env)
            @app = app
          end
          def call(env)
            @env = env
            env[:machine].config.vm.networks.each do |type, options|
              next unless type == :private_network && options[:ip]
              try ||= 0
              try  += 1
              inter = Pathname.new(@env[:machine].provider.driver.rootfs_path).join("etc/network/interfaces")
              begin
                inter.open("w") do |f|
                  f << <<-INTER_CONTENT
                    auto lo
                    iface lo inet loopback

                    auto eth0
                    iface eth0 inet static
                      address #{options.fetch(:ip)}
                      netmask 255.255.255.0
                      gateway 0.0.0.0
                  INTER_CONTENT
                end
              rescue Errno::EACCES
                puts "Need to use sudo to configure network interface"
                command = "sudo chmod 666 #{inter}"
                puts command
                `#{command}`
                redo if try == 1
              end
              break
            end
            @app.call env
          end
        end
      end
    end
  end

Tks Robert!
Is that needed for other debian versions? Are up for sending a PR? We'd
just need to add a check if the guest type is debian && is the expected
version before writing the file on the guest container ;)
Oh, and another nice to have would be to remove the file on machine halt :)

Seems to be also needed for Debian 7 (wheezy) as it always starts dhcp no matter what network configuration I set in my Vagrantfile.
