Hmm, I wonder if VirtualBox is hitting the same popcnt bug that was fixed in qemu... Could you please try a patch from here http://thread.gmane.org/gmane.comp.emulators.qemu/174532/focus=174567 ? It should be applied to src/recompiler/target-i386/translate.c, make sure that it goes to a section marked as 'case 0x1b8: /* SSE4.2 popcnt */'. -- Andriy Gapon
