How to activate the XP system installed by the virtual machine

Q: I only came into contact with the virtual machine. I feel very fun. I can install a variety of systems. My system is Win7. Sometimes I still need to use XP, so I installed an XP in the virtual machine, but I found it in the system. There is no activation, how do you need to activate it? A: The XP installed on the virtual machine needs to be activated? You will not be the official original version of the installation? In the era when XP was already in the past, the next Ghsot version on the Internet will do. However, it should be noted that the virtual machine installation Ghsot system must first partition and format the virtual machine's hard disk, otherwise it will not be able to install. If you don't want to reinstall, XP's serial number is also a large search on the Internet, you can activate it yourself.
