[Vagrant] ネットワークカードが複数搭載されたPCでのパブリックネットワーク設定

有線と無線の両LANカードを搭載したPCのように、ネットワークカードが複数搭載されたPCでパブリックネットワークを設定する場合には、ブリッジされたインタフェースにどのネットワークインタフェースを使うか指定しないとならない。

都度手動で指定する

Vagrantfileにネットワークインタフェースを指定しないと、VM立ち上げ時に聞いてくる。

Vagrantfile

config.vm.network "public_network"

1	config.vm.network "public_network"

VM起動。

立ち上がったVM上でネットワークカードを確認。テストした環境にはDHCPサーバーがあるので、IPアドレス(192.168.1.16)は自動で振られている。
