It seems that properties of the host CPU are passed over to the VM guest as indicated here, https://forums.virtualbox.org/viewtopic.php?f=10&t=33954 There is a technical difference between Virtualisation and "Emulation". I found some elaboration about this here: http://www.thefreecountry.com/emulators/pc.shtml QEMU is an emulator, so maybe this would be the tool of choice to study old processors. But I guess while you can test a lot with such a setup, the real proof of the pudding is in the eating, i.e. some bugs will only show out in the wild. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
