概要

KUSANAGI for Vagrant マニュアルを参考に Vagrant と VirtualBox で KUSANAGI の開発環境の構築中に発生した問題の解決方法です
vagrant up 後 ==> default: Machine booted and ready! で小一時間止まりました
原因はゲスト OS から名前解決に失敗していることでした
Vagrantfile の config.vm.provider :virtualbox do |vb| ~ end 内に vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"] を追記したりパソコンを再起動したりしたところ解決しました

環境

MacBook Pro (Retina, 15-inch, Mid 2015)
macOS Mojave
Vagrant 2.2.0
VirtualBox 5.2.20

Vagrantfile

config.vm.synced_folder は変更して欲しいんですが、コピペで動作するかもしれません

  # `vagrant box outdated`.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: 22, host: 12222, id: "ssh"

  # 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"

  # 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 "/Users/username/kusanagi/repository/wp-content", "/home/kusanagi/FQDN/DocumentRoot/wp-content",
    owner: "httpd", group: "www"

  # 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|
      vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
      vb.gui = false
      vb.memory = "2048"
  end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # 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
end
