I guess a less convoluted way of stating my logic would have been: "Maybe it's just protected mode keeping you from doing it." And/or: "You can do things in real mode that you can't do in protected mode. Maybe this is one of them." And/or "Can real mode even stop you, given the "protections" of protected mode aren't in place yet? Being the "opposite" of protected mode, does real mode even try and stop you from doing anything? Isn't that the point of real mode? Let you do anything to get the system going?"

These "protections" are the processor preventing programs from doing certain things, and I was wondering if one of those things is flipping that VT-X locking bit. > > In real mode things haven't been set in stone yet. There's more flexibility. From real mode the processor can go into one mode or another. But once you go out of real mode, you can't come back without a power cycle. Given the flexibility and "unsetness" of real mode, still being able to flip that bit goes with the theme of real mode in my mind. > > Jake > > Sent from my iPhone -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
