Guest execution in other processor operating modes need to be specially handled by the VMM"; see also lesson 24 how to do this from Linux (not that the code is pretty dated, so might not work as-is with current kernels) more up-to-date code can be found here. Also beware that this sample code is more complicated than strictly booting the logical processor in virtual 8086 mode; its ultimate goal is make some real-mode BIOS calls.
