That would depend on the type of virtualization, with hardware virtualization (Xen, ESX, Hyper-V) there is, like D.W. says, no problem.

I suggest you put them on a LAN and your students can surf to them through a VPN setup. It's a lot safer than putting them just on the internet. If you just put them on the internet, you get attention …

Regardless of what virtualization technology you use. Once the attacker has access to the hardware, it's game over.
