A machine (and a virtual environment) can indicate via the BIOS tables or ACPI that there are less "possible" cpus. That is actually very common. The difference between actual and possible cpus only has to be the number of processors that could be brought up later. In a regular system that is pretty much zero. In a fancy system with actual hotpluggable cpus there would be a difference but usually the number of hotpluggable cpus is minimal. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
