概要

新MacOSでVirtualBox × Vagrantの環境構築を試みたところ

環境自体はエラー無く作成でき、またSSH接続で環境内に入ることが出来るが、
作成した環境にpingを投げかけても到達出来ない事象に遭遇した。

環境作成にあたり利用したVagrantファイルの記述は下記。

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

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "centos/7"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.network "forwarded_port", guest: 80, host: 30080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  # config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.network :private_network, ip: '192.168.55.10'

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  # config.vm.synced_folder "../data", "/vagrant_data"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.
  config.vm.provider :virtualbox do |vb, override|
    vb.name = "HOGEHOGE"
    vb.memory = "2048"
    # IPv6
    vb.customize ["modifyvm", :id, "--natdnsproxy1", "off"]
    vb.customize ["modifyvm", :id, "--natdnshostresolver1", "off"]
  end

  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
  # documentation for more information about their specific syntax and use.
  # config.vm.provision "shell", inline: <<-SHELL
  #   apt-get update
  #   apt-get install -y apache2
  # SHELL

  # plugin
  if Vagrant.has_plugin?("vagrant-vbguest") then
      config.vbguest.auto_update = true
  end
end

原因

Vagrantのバージョンが微妙に古く、バージョンを最新化して2.2.19に引き上げた。

そうすると環境の構築段階で下記のエラーが発生。

The IP address configured for the host-only network is not within the
allowed ranges. Please update the address used to be within the allowed
ranges and run the command again.

  Address: 192.168.55.11
  Ranges: 192.168.56.0/21

Valid ranges can be modified in the /etc/vbox/networks.conf file. For
more information including valid format see:

https://www.virtualbox.org/manual/ch06.html#network_hostonly

どうやらプライベートIPがVirtualBoxで定められている範囲外になっている様子。

VirtualBoxのマニュアルにも書いてあるみたい、、

On Linux, Mac OS X and Solaris Oracle VM VirtualBox will only allow IP addresses in 192.168.56.0/21 range to be assigned to host-only adapters. For IPv6 only link-local addresses are allowed. If other ranges are desired, they can be enabled by creating /etc/vbox/networks.conf and specifying allowed ranges there. For example, to allow 10.0.0.0/8 and 192.168.0.0/16 IPv4 ranges as well as 2001::/64 range put the following lines into /etc/vbox/networks.conf:

そのためVagrantファイルの記述を以下に変更した。

-  config.vm.network :private_network, ip: '192.168.55.10'
+  config.vm.network :private_network, ip: '192.168.56.10'

その後、無事に環境が作成されてpingを通ることを確認した。

まとめ

VirtualBoxとVagrantのバージョンの組み合わせは大事！

めっちゃハマったー。
