<< BHyVeあれこれ/vm-bhyve による VM の管理・運用の試み/とりあえずチュートリアル >>

3.2 とりあえずチュートリアル

  1. sysutils/vm-bhyveのインストール 
    # cd /var/ports/bhykx/sysutils/vm-bhyve/
# make install
  2. vmを立ち上げる 
    # vm init
# ll -R /vm

  3. とりあえずVMを作ってみる

    　vm(8) の QUICKSTART にしたがって...

    1. `vm switch create public' 
      # vm switch create public
# ll -R /vm

      • /vm/.configにsystem.confとnull.isoが作られる
        • system.confの中身は`switch_list="public"'
          • これはswitchの識別名
        • null.isoはISOイメージのテンプレートか？
      • bridge0インターフェースが`vm-public'という名前で作られる

      • 指定したVMの雛型が作成される
        • default.confにしたがって空のVMイメージを作成
          • /vm/.templates/default.confは予め作っておかないといけない

          • ネットワーク名: public
          • VMファイル名(disk0_name): disk0.img
            • /vm/my-guestにVMイメージ(disk0.img)が作成される
              • デフォルトは20GB (変えたいときは`-s'で指定)
              • `truncate -s 20g disk0.img'しただけ
            • /vm/my-guest/my-guest.confが作成される
              • /vm/.templates/default.conf + "VMのUUID"
