This is a result of inadequate real mode emulation as required by VT-x. 
This should not be an issue with SVM which can do paged real-mode. Leendert
van Doorn did the initial work but is now at AMD, so it is unlikely that
he will fix it. There is no indication that non-MS operating systems are
important to the Xen community with respect to full virtualization.
