So with all this virtualization going on, one computer can run multiple copies of an OS (or multiple OSs), all acting like they own the whole computer. With only some fancy shim layer keeping them from corrupting themselves and everything else, what are the implications for security? Security is an issue that has been raised more frequently as computers have become more powerful and the network more pervasive. I mean, viruses spread fast enough when the World Wide Web was mostly single computers with modems dialing up to servers. In this day of broadband everywhere and constant connections, doesn't virtualization present a special problem? Doesn't a machine running 10 virtual servers just mean that a virus gets to invade 10 servers for the price of entering one machine? Let the SPAM flow! NOT!
