Once you are there, you are near the point where you created a virtual architecture, which could run on any real architecture which gets supported by a hypervisor backend. I'd love that :) I know it is tricky to combine this with the upcoming hardware virtualization support. But it's at least a worthwhile thought experiment. tglx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
