Exactly, but I suspect that Rod was actually asking what UML does about the kernel timer... ;-) Folks often "write-off" the timer patch as pertaining only to z/VM, but when we look at it there are other applications (as Johns and Rod have raised). ISTR Alan C. mentioned the UML aspect way back when this list was first discussing whether the patch might get integrated into the kernel. Unfortunately, the timer patch doesn't scratch a large enough itch for the community at-large. As more shops use virtualisation -- not just on z/VM -- in consolidation exercises, we might see that change. Cheers, Vic
