我的环境： MacOS 10.12.6 的VirtualBox：5.2.18 无业游民：2.1.4
每次我虚拟化虚拟机时，都会出现这样的警告
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
default: SSH address: 127.0.0.1:2222
default: SSH username: vagrant
default: SSH auth method: private key
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Connection reset. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Connection reset. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Connection reset. Retrying...
它会在这种情况下保持很长一段时间，但几分钟后总能正常工作：
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Connection reset. Retrying...
==> default: Machine booted and ready!
==> default: Checking for guest additions in VM...
我的流浪汉有什么问题吗？
非常感谢！
