See http://user-mode-linux.sourceforge.net/slides/wvu2002/wvu2002.htm, which are the slides from a talk I gave at WVU and MorLUG in which I explained this more clearly than I had managed before. The section that's relevant here starts at http://user-mode-linux.sourceforge.net/slides/wvu2002/img9.htm > How would this be better than MOSIX, or other clustering solutions? MOSIX (or Compaq's SSI) would certainly be a way of doing it. It happens that there's a particularly simple way of doing it with UML. You'd partition UML's 'physical' memory between the hosts, and use the fact that those pages are really virtual to fault them between hosts as needed. This would perform particularly badly, but its simplicity appeals to me. Jeff
