Vagrant无法在配置的（“config.vm.boot”超时“值）时间段内与来宾计算机通信

########################

如何解决上述问题?？谁能帮我一下吗？我被它缠住了好几个小时

我应该如何在文件中添加或编辑行“config.vm.boot_timeout”

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.
