推荐答案

虚拟机本质上与物理机没有什么不同.软件无法判断它是在另一台计算机上运行，​​并且可以像在真实PC上运行一样的方式连接到网络或互联网.如果您想保护虚拟机免受诸如入侵之类的攻击，那么答案是肯定的，请在您的VM上安装防火墙.

A virtual machine is essentually no different than a physical machine. Software can''t tell it is being run on one or the other and will connect to the network or internet the same way as if it was run on a real PC. If you want to protect your virtual machine from attacks like for instance intrusion, then the answer is yes, do install a firewall on your VM.
