The main roadblock to VM-type systems on Intel is the lack of the hardware support (which has been added to mainframe over the years) for efficient virtualisation.

Well it might then be possible to run M$ code on an S/390... that's the best possible reason for never doing any such thing... More seriously, the question would have to be how and why? The performance would *suck* - why waste all those MF mips emulating an Intel chip?
