I build dreamcloud/centos7 vagrant box as practise, it is a dev ready vm:

  • Guest Tool, shared folder
  • gcc/git/python/pip

Here is demo how to launch centos vm from this base, add 2nd host-only interface for private network.

Vagrantfile

Vagrant.configure("2") do |config|
    config.vm.box="dreamcloud/centos7"
    
    config.vm.define "centos7dev" do |ct7|
        ct7.vm.network :private_network, ip: "10.120.0.15"
        ct7.vm.hostname = "centos7dev"
        ct7.vm.provider :virtualbox do |vb|
            vb.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
            vb.name="centos7dev"
            vb.memory=1024
        end
    end
end
