So\nkvm uses virtualized vm86 mode to run real mode code.

On a\ntransition back to protected mode, if we see that the guest did not touch\na forced segment, we restore it back to the original protected mode value.\n\nThis pile of hacks breaks down if the gdt has changed in real mode, as it\ncan cause a segment selector to point to a system descriptor instead of a\nnormal data segment.
