vagrant导出的box不能启动

Question

vagrantfile是这样的：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|
  
  config.vm.box = "centos7"
  config.vm.hostname = "vagrant-dev"
  
  config.vm.network "private_network", ip: "192.168.33.3"
  
  config.vm.synced_folder "d:/wnmp/www/", "/var/www"

  config.ssh.username = 'root'
  config.ssh.password = 'vagrant'
  config.ssh.insert_key = 'true'
  
  config.vm.provider "virtualbox" do |vb|
     vb.memory = "1024"
     vb.cpus = 2
  end
end

打包导出为box的时候是这样做的：
1、注释掉config.vm.network "private_network", ip: "192.168.33.3"这一行。

2、导出box

vagrant package --output centos7

使用导出的box：

1、添加box

cd d:/vagrant_env    //box文件保存在这个目录
vagrant box add centos7 centos7.box

2、启动，这时报错。
启动时开启和注释掉config.vm.network "private_network", ip: "192.168.33.3"这一行都会报错。

cd d:/vagrant_env    //上面的vagrantfile也在这个目录

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

Answer 1

config.ssh.insert_key

这一行去掉试试。
