But, using that definition, we haven't done any good virtualization in Linux that I can think of. Besides some vague ranting I heard about zSeries (the real IBM mainframes) I can't think of anything that does this today.

Can you think of any? -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
