我正在使用导出的Vagrant盒子 . 文件扩展名为.ova . 我将其导入VirtualBox并将其id放入“/home/user/Documents/vagrant/.vagrant/machines/default”文件夹中的“id”文件中 . 在此之后我运行“vagrant up”命令 . 我得到以下输出

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.

SSH超时，虽然身份验证失败，但我仍然能够使用“vagrant ssh”SSH进入我的机器，但是我没有创建我在vagrant文件中定义的同步文件夹 .

我在用：

Vagrant version: Vagrant 1.8.1

VirtualBox version: 版本5.0.40

Host operating system: Ubuntu 16.04 LTS

Guest operating system: CentOS 7.0

Vagrantfile

Vagrant.configure(2) do |config|
config.vm.box = "oneops"

 # Use the vagrant-cachier plugin, if installed, to cache downloaded packages
  if Vagrant.has_plugin?("vagrant-cachier")
    config.cache.scope = :box
  end

  config.vm.network "forwarded_port", guest: 3001, host: 3003
  config.vm.network "forwarded_port", guest: 3000, host: 9090
  config.vm.network "forwarded_port", guest: 8080, host: 9091
  config.vm.network "forwarded_port", guest: 8161, host: 8166

  config.vm.provider "virtualbox" do |vb|
   vb.gui = false
   vb.memory = 6144
   vb.customize ["modifyvm", :id, "--cpuexecutioncap", "70"]
  end

  config.vm.synced_folder "~/Documents/Share/", "/home/vagrant/Documents/Share/"
end

End Result: 我无法在主机和来宾计算机之间创建同步文件夹 . 当我尝试使用"vagrant halt"暂停机器时，我得到以下输出

$ vagrant halt
==> default: Attempting graceful shutdown of VM...
    default: Guest communication could not be established! This is usually because
    default: SSH is not running, the authentication information was changed,
    default: or some other networking issue. Vagrant will force halt, if
    default: capable.
==> default: Forcing shutdown of VM...

任何人都可以帮我弄清楚这里可能出现的问题吗？

ssh vagrant virtualbox
