分析：
從上面啟動過程 No guest additions were detected on the base box for this VM! 可以看出 centos/7 缺少 Virtualbox Guest Additions
解決：
vagrant 安裝 vagrant-vbguest 插件互拾，在 Vagrantfile 中配置 synced_folder
- 安裝 vagrant-vbguest
vagrant plugin install vagrant-vbguest
- Vagrantfile 配置共享目錄沟娱，掛載位置不能使用 /vagrant
Vagrant.configure("2") do |config|
config.vm.synced_folder ".", "/share"
end
- 啟動過程會自動安裝 Virtualbox Guest Additions，啟動后配置的共享目錄可以雙向讀寫
