It is capable of running guest operating systems that "believe" they are running on a bare machine. VM could be considered "prior art" for VMWare. Linux runs as a guest OS under VM, along with the conventional mainframe OS, MVS. VM can run many copies of Linux simultaneously. I am not sure it is quite fair to call this a "smoke and mirrors" port. Disclaimer: I don't work for IBM, and someone from the company might like to explain this more accurately?
